In the last years of the 20th century, the astrophysical community was stunned to learn that the universe was driving itself apart. He showed for the first time that the driving force behind the Big Rip if it happens could be the universes cosmic viscosity. LHEA at In 2003, NASA's WMAP satellite took images of the most distant part of the universe observable from Earth. Entropy would continue to increase as well: Star formation itself will end in 100 trillion years as all the matter to fuel them is exhausted. Credit: Hubble Heritage Team (AURA/STSCI/NASA); US Mint, Image to right: The picture on the right was taken three weeks after the one on the left. Jay Norris. Trodden is a theorist for one such planned experiment at the Large Synoptic Survey Telescope, currently under construction, that will image the entire sky every few nights at unprecedented detail. Its hard to imagine anything coming after that, black dwarf supernova might be the last interesting thing to happen in the universe. Theres little we know for sure; in a universe of infinite possibilities, anything can happen. Dysons concept on eternal intelligence was a good attempt at tackling how the universes end might not be civilizations, but like the Big Crunch, it cant overcome dark energys implications. For decades, scientists had known that distant galaxies all move away from us, with the farther ones moving the fastest. You are in the Universe. If expansion continues, the universe will never truly end. measurements But what if theres more out there, and our universe is but a small part of a multiverse? That's just 100 million years . SPHEREx will carry out the first all-sky spectral survey at wavelengths between 0.75m and 5m with spectral resolving power ~40 between 0.75 and 3.8m and ~120 between 3.8 and 5m At the end of its two-year mission, SPHEREx will .

This leaves the universe with only two possible endings: Big Crunch or Big Chill. Planet Venus: 19 interesting facts about the scorching . The team hopes that perhaps a little blip on the otherwise uniform CMB would betray the existence of such a false vacuum in the distant past, as well as provide the first concrete evidence for a multiverse. The Big Crunch:The Big Crunch is a classic scenario for how the universe could end. The region surrounding Sagittarius A*, the Milky Way's own . of the universe centered on either a re-collapsing The Beginning and End of the Universe Cosmology is the scientific study of how the Universe began more than 13 billion years ago, how its properties have changed from that time to the present, and what its eventual fate might be. As soon as few billion years from now, Although the universe started with a Big Bang, analysis of recent cosmological measurements allows a possibility that it will end with a Big Rip. Although NASA maintains the universe will go on forever, the same is not true for human life. At some point, the universe might stop growing because of the gravitational pull of all the matter inside of it, and then it would start to collapse back into itself. Although the Scientists theorized that gravity would eventually slow and possibly even completely reverse this expansion. Despite everything we've learned about our Universe, numerous existential issues have no clear an. The patterns show clumps of matter that eventually formed into galaxies of stars. Their prime target is the cosmic microwave background (CMB), the oldest light scientists can see, which dates back to when the universe was just 380,000 years old. No one knows what dark energy is, so we cant be sure how it will behave in the future. We now know (as of 2013) that the universe is flat with only a 0.4% margin of error. If the cosmological constant continues to dominate, the universe will continue to accelerate and thats it.. (MTU) & Forum piecing it together will likely follow from an own Galaxy will no longer be able to hold itself together. They are very small.

And other parts of the universe, very far away, might be quite different from the universe closer to home. The beings thinking sessions would slow over time, but there could be an infinite number of them through this energy rationing. Once this was used up, the beings would enter a state of non-energy consumption; they'd be in stasis, while the energy remained. Credit: SOHO - ESA & NASA, Image above: How Big is the Milky Way?

Previously, speculation on the Only about 1 per cent of the stars that exist this day roughly a billion trillion, in all will blow up this way, with others such as our Sun failing to have enough mass to create a supernova explosion. The driving idea: What if the expansion of the universe does not last forever? This is the first time that Chandra has detected this phenomenon from a star other than the Sun, Dark, narrow, 100 meter-long streaks running downhill on the surface Mars were believed to be evidence of contemporary flowing water. As soon as few billion years from now, the controversial scenario holds, dark energy will grow to such a magnitude that our own Galaxy will no longer be able to hold itself together. The first of these black dwarf supernovae is predicted to occur in about 10 to the 1100th years, a length that read out would mean. Now, it depends on the nature of the dark energy, how the universe will come to an end. If you know your browser is up to date, you should check to ensure that Eventually, there will be nothing left to go off and the universe will fall into silence, with nothing ever happening again. By analyzing how gravity affects galaxies light, and analyzing their three-dimensional positions and movements in space, the scientists should have enough information to finally unlock some of dark energys secrets. of gravity. The Big Bang theory describes the expansion and evolution of the universe from this initial superhot, superdense state. & Make a pinwheel galaxy pinwheel! Does it arise from quantum fluctuations in the vacuum of space? U. & The image shows the furthest we can see using any form of light. A scientist has revealed a "sad, lonely, cold" picture of the universe as it comes to its end. Closest known black hole. The Local Group will remain bound, and the galaxies within it will attract and merge. That would be as bad as it sounds. As the universe expands, all the energy needed to keep the stars and galaxies alight will be used up. The Big Crunch is a classic scenario for how the universe could end. ~3,000 light-years. Credit: NASA and J. Blakeslee (JHU), Image above: What is the furthest we can see? In this scenario, dark energy the mysterious substance that acts in opposition to gravity pulls everything apart. Big Crunch or a And while there are no definite answers yet, those discussions have come up with a few interesting possibilities. The Universe is a big, open place. Galaxies will have dispersed, black holes will have evaporated, and the expansion of the universe will have pulled all remaining objects so far apart that none will ever see any of the others explode. dark energy. Braden is part of a research team trying to predict what such a signature would look like. The universe would continue to cool, running down, but after a certain point another half of the remaining energy reserves would be released, thanks to an as-yet-unknown technology created by the beings, allowing them to think once again. NASA's James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. The only way this makes sense is if the universe itself is expanding. recent cosmological A series of stills showing the Milky Way-Andromeda merger, and how the sky will appear different from Earth as it happens. Even the smallest things on Earth are part of the Universe. The results suggest the geometry of the universe is flat and will expand forever. be it galaxies or exo-planets. Big Chill. Although the universe started with a Big Bang, analysis of cosmological measurements allows a possibility that it will end with a Big Rip. The Big Freeze: How the universe will die. If so, our universe would exist in a state known as a false vacuum, where we wrongly suppose that we exist in the most stable state, but its still possible to drop to another one suddenly. If this is true, then dark energy is the major driving force behind the fate of the universe and it will expand forever exponentially. While our own universe is homogenous and roughly the same everywhere, taking such a large view might reveal that its just a tiny pocket with its own physical parameters and laws, different from the larger multiverse. Get unlimited access for as low as $1.99/month. Braden explains this would result in a phase transition, a change similar to how water changes from liquid to gas at its boiling point only for the entire universe. Has the universe always been expanding? For decades, scientists had been trying to link mainstream physics understanding of viscosity with a related concept: cosmic viscosity, which tells us about the universes resistance to accelerating expansion. do, however, is see whether a false vacuum ever existed in our own universe in the very distant past, which could help tell us whether such a collision is likely to happen again. When did the universe begin? That is according to new research from Matt Caplan, from Illinois State University, which has been accepted for publication in the Monthly Notices of the Royal Astronomical Society. NASA Technical Rep.: What scientistscando, however, is see whether a false vacuum ever existed in our own universe in the very distant past, which could help tell us whether such a collision is likely to happen again. NASA's Hubble Space Telescope has captured a spectacular fireworks display in a small, nearby galaxy, which resembles a July 4th skyrocket. At some point, the universe might stop growing because of the gravitational pull of all the matter inside of it, and then it would start to collapse back into itself. NASA's James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Explanation: His work originally focused on bulk viscosity the measurement of a fluids resistance to expansion or contraction and how moving fluids behave when approaching the speed of light. It has since been suggested that they may instead be formed by flowing sand, Morning Aurora: Nasa astronaut Scott Kelly captured this photograph of the green lights of the aurora from the International Space Station in October 2015, Must be at least 6 characters, include an upper and lower case character and a number, Please enter a name between 1 and 40 characters, You must be over 18 years old to register. Jerry Bonnell (USRA) If the density of the universe is less than the critical density, then the universe will expand forever, like the green or blue curves in the graph above. As the cosmological constant continues to drive the acceleration of the universe, all the galaxies outside our immediate neighborhood will be too far away to be visible in a few trillion years their light will simply never reach us. Image to right: Amoebas live on Earth. Specific rights apply. atoms might not be able to withstand the The WMAP satellite measures the basic parameters of the Big Bang theory including the fate of the universe. How did it start? Could these other universes affect the ultimate fate of our own? For now, as with many cosmological theories, well have to wait and see. So how big is the universe? Such a collision would spell an immediate end to our universe as everything changes to a new state. Want to bookmark your favourite articles and stories to read or reference later? Enjoy and share some of Hubble's most stunning images of galaxies, nebulas, solar system objects, and more, or grab some popcorn and take in a show with our science . There was even some speculation that a Big Crunch could produce a Big Bounce right afterward, Big Banging a new universe into creation. As the car goes faster and faster the speed of the velocity change itself increasing over time the car would eventually fly apart in pieces as friction took its toll. The WMAP satellite measures the basic parameters of the Big Bang theory including the fate of the universe. Many current theories suggest dark energy is a cosmological constant, a kind of uniform energy that exists throughout space. Future NASA missions will continue to search for clues to the ultimate size and scale of our cosmic home.

GSFC We live on a planet called Earth that is part of our solar system. The driving idea: What if the expansion of the universe does not last forever? It would take the Space Shuttle seven months to fly there. The answer is that no one really knows. Finally, our universe would end in an explosion, a singularity of literally infinite energy. There is a growing consensus among cosmologists that the total density of matter is equal to the critical density, so that the universe is spatially flat. ANDREW HAMILTON, JILA, UNIVERSITY OF COLORADO. The universe will eventually use up its entire supply of star-forming material and star formation will cease Many trillions of years from now, the last star will burn out and only stellar remnants will remain Stellar remnants will cease to exist in many trillions of years, leaving behind a universe filled with nothing but radiation That's why the sun, which is a million times the size of the Earth, looks so small. Recent speculation now includes a pervasive growing field of Join thought-provoking conversations, follow other Independent readers and see their replies. The results suggest the geometry of the universe is flat and will expand forever. It will also not happen to most black dwarfs. As with the end of the universe, this is a long way off. Find out more about what a galaxy is and how many there are. If the cosmological constant is the dominant thing in the universe, explains Mark Trodden, a co-director for the Penn Center for Particle Cosmology at the University of Pennsylvania, then instead of speeding up unsustainably and tearing itself apart, the universe would just keep expanding forever. The UN's space agency released a video explaining the world didn't end on December 21. The image reveals the black hole at the centre of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster. In the 1970s, Freeman Dyson was one of the first physicists to contemplate the end of the universe using modern cosmology. ultimate fate Observational cosmology uses telescopes like the Hubble to reach back in time to find the faint echoes of the Big Bang. And our galaxy is just one of millions and millions. The final basic possibility for the universe's end is known as the Big Rip. In physics, finding an infinity is likely an indication that we are missing part of the puzzle, he says. Black holes will evaporate, matter itself will eventually decay into radiation and the universe will be a cold, lightless, lifeless place for the rest of eternity. Imagine you go to a very, very large scale much larger than our current observable universe, explains Jonathan Braden, a cosmologist at University College London. One important question concerning the ultimate fate of the universe concerns its inhabitants: Can intelligence and consciousness overcome entropy, the eventual wearing down of our universe? As soon as few billion years from now, the controversial scenario holds . By clicking Create my account you confirm that your data has been entered correctly and you have read and agree to ourTerms of use,Cookie policyandPrivacy notice. Gravity might slow the expansion rate down over time, but for densities below the critical density, there isnt enough gravitational pull from the material to ever stop or reverse the outward expansion. The cosmos will be almost entirely dark, littered with black holes and the remains of stars that have long-since burnt out. Discover the cosmos! Is it just a part of gravity well have to add to the laws of physics? According to NASA There are three possibilities how The universe could end: Big Rip, Big Crunch or Big Chill. NASA always has some intriguing science stuff in it's bag that leaves the world mesmerised. Theyd effectively come back to life, never aware of the break in their thoughts.

Scientist predicts how the universe will end: 'A bit of a sad, lonely place', {{ #verifyErrors }}{{ message }}{{ /verifyErrors }}{{ ^verifyErrors }}Something went wrong. Big Rip. Its a big question all right, but weve made surprising headway toward an answer. As with the end of the universe, this is a long way off. In this universe, there is sufficient mass in the universe to slow the expansion to a stop, and then eventually reverse it. Its very difficult to tell how the universe will end just from local measurements, explains the University of Pennsylvanias Mark Trodden. You can opt-out at any time by signing in to your account to manage your preferences. Each email has a link to unsubscribe. In the new article led by Jim Green, the agency's chief scientist, a NASA group offers a sample scale to use as a starting point for discussions among anyone who would use it, such as scientists and communicators.They envision a scale informed by decades of experience in astrobiology, a field that probes the origins of life on Earth and possibilities of life elsewhere. The balance of forces and energy cause the Universe to expand, first accelerating, then decelerating and then accelerating again. Imagine a driver who keeps a foot on the gas pedal of a car with no top acceleration. This merger will begin occurring roughly 4 billion years in the future . Over unimaginable eons, each orders of magnitude longer than the current age of the universe, expansion will pull galaxies apart, snuff out stars, and tear matter into its elementary constituents. A similar thing happens to a universe with relentless acceleration: Galaxies would be destroyed, the solar system would unbind and eventually all the planets would burst asunder as the rapid expansion of space rips apart its very atoms. Welcome to the Universe. After that, stars, The results are interesting, but Disconzi acknowledges that Big Rip theories still require a bit of work to make sense, particularly the part about infinite energy being released. NASA SEU Edu. The WMAP satellite measures the basic parameters of the Big Bang theory including the fate of the universe. In our model, Proxima Centauri (and any planets that might be around it) would be another quarter, two soccer fields away. According to NASA, the prediction that the world would end four . Michigan Tech. This suggests that the Universe is infinite in extent; however, since the Universe has a finite age, we can only observe a finite volume of the Universe. dark energy will grow to such a magnitude that our How far away is the nearest star to our sun? Once this was used up, the beings would enter a state of non-energy consumption; theyd be in stasis, while the energy remained. When it switches on in 2022, the telescope will study billions of galaxies every night, giving astrophysicists an unparalleled ability to test galactic behavior. Such a prehistoric false vacuum would necessarily be much smaller than the scale of our universe (just a bubble within our bubble), but it might still leave behind a hint that something curious happened long ago. Is A Subatomic World Possible And What Would It Look Like. Unless it turns out dark energy can change its nature dramatically, the Big Crunch seems an unlikely way for the universe to end. It could be billions of years from now, or it could be tomorrow. Regions of space such as this are where new stars are born from a mixture of elements and cosmic dust, The first ever image of a black hole, captured by the Event Horizon telescope, as part of a global collaboration involving Nasa, and released on 10 April 2019.

The results suggest the geometry of the universe is flat and will expand forever. Stars less than about 10 times the mass of the sun do not have the gravity or density to produce iron in their cores the way massive stars do, so they cant explode in a supernova right now, said Professor Caplan. NASA Found A Giant Glowing Wall At The End Of the Universe. Last observed supernova in Milky Way. allows a possibility that it will end with a Basically, our cosmos might be like one of the bubbles boiling in a pot of water, he says, just one of many with their own sets of laws and constants. mysterious repulsive energy that rips virtually everything apart. This black hole resides about 54 million light-years from Earth, Pluto, as pictured by Nasa's New Horizons spacecraft as it flew over the dwarf planet for the first time ever in July 2015, A coronal mass ejection as seen by the Chandra Observatory in 2019. NASA - National Aeronautics and Space Administration, Image to right: Our sun, the nearest star, is 93 million miles away. But there are still many details to fill in, and scientists like Vanderbilt University mathematician Marcelo Disconzi will provide those details. The universe is modeled as a fluid, in large scales, so Disconzis work proved instrumental in starting to understand cosmic viscosity. universe's fate is still a puzzle, How will our universe end? (That can happen in extreme astronomical situations, such as an exploding star.) As such, while some theorists have speculated our future descendants could transfer information to new baby universes via wormholes or black hole formation, it appears inevitable that after some point, intelligence in our own universe will simply be impossible. SPHEREx, the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and ices Explorer, isa NASA MIDEX mission planned for launch in 2024. It's this that would last long after the rest of the universe had faded to black, with those black dwarfs turning supernova and illuminating the universe even as everything else had disappeared. The Sun is now a microscopic speck of dust, as are its nine planets, whose orbits are represented by the flat disc of the coin. This site is protected by reCAPTCHA and the GooglePrivacy policyandTerms of serviceapply. The most massive black dwarfs will explode first, said Professor Caplan, and the smaller ones will follow. This article originally appeared in print as "Game Over. An accelerating universe means that eventually parts currently in contact will be isolated from each other, and energy stored in these areas would be inaccessible. Who would mind slow thought processes if time stretches on forever? No one had successfully modeled how a viscous fluid would act at relativistic speeds, but working with colleagues in the Vanderbilt physics department, Disconzi successfully did it. Things you can't see are in it, too. Even at its very end, no matter how far into the future we go, the Universe will always continue to produce radiation, ensuring that it will never . Further study of the dark energy with future experiments and space missions is needed to understand its nature and effect on the rate of future expanison. If the density were high enough, then gravity would eventually slow the expansion of the universe and cause it to re-collapse in a "Big Crunch." NASA's next big telescope could tell us if the universe will rip itself apart Evan Gough NASA's Nancy Gracy Roman Space Telescope won't launch until 2027, and it won't start operating until. The End of the Universe: Fire or Ice? Even though the explosion is as bright as a billion suns, it is so far away that it is just a speck of light. Take a . Authors & editors: Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Recent observations of distant supernova have suggested that the expansion of the universe is actually accelerating or speeding up, like the graph's red curve, which implies the existence of a form of matter with a strong negative pressure, such as the cosmological constant. Today, smaller stars that cannot explode into a supernova shrink down into white dwarfs, changing the trillions of years that are left before the universe dies out. It's a small part of the Milky Way Galaxy. Current theories predict that if this so-called Big Rip is in our future, it will take another 22 billion years to arrive. Further study of the dark energy with future experiments and space missions is needed to understand its nature and effect on the rate of future expanison. But when cosmologists calculated just how much its slowed down, they got a negative result the expansion of the universe is speeding up! The cosmos will come to a close through a cold and lonely death called the Big Freeze. Thats it might not sound like much, but its a bleak way to go. How To Build An Emergent Spacetime In The Laboratory, 3 Science Hoaxes Of Today: From Theranos To Fake Fossils, Winter May Seem Cold, But It's Nothing Compared To Outer Space. Given all the matter in the cosmos, the force of gravity should be slowing down that expansion. It could result in a combination of the two universes, or it could create something new entirely. Further study of the dark energy with future experiments and space missions is needed to understand its nature and effect on the rate of future expanison. The only thing we can be sure of is that, eventually, the world will come to an end. Imagine that our entire Solar System were the size of a quarter. Its famous and extremely high-tech James Webb Space Telescope has captured some of the most stunning images from space. An improved theory might show that the universes expansion rate doesnt really go all the way to infinity, no matter how large the Big Rip becomes. First, as the end times approach, the beings would need to store a finite amount of energy in the universe; they would then use half this energy to power their thoughts (the only remains of their super-advanced lives). javascript is enabled. The other scenarios weve considered assume that our universe is all there is. What Happens To Us If Earth Falls Into A Black Hole? What time does the Artemis 1 Orion spacecraft splash down on Dec. 11 to end NASA's moon mission? Unfortunately, the discovery of dark energy dealt the Big Crunch a deathblow, since it suggests the universe will expand forever. We don't even know how big the Universe is! Dark energy is so baffling that it has taken the better part of two decades to understand the theory enough to even design experiments to study it, let alone figure out if the Big Freeze lies in our future. ", Most Distant Dark Matter Ever Found Dates Back 12 Billion Years, A New Idea for How Dark Matter Came to Dominate the Universe. If dark energy in fact plays a significant role in the evolution of the universe, then in all likelihood the universe will continue to expand forever. He proposed that in the distant future, intelligent beings might figure out a way to cheat a Big Freeze-like scenario. planets, and then even How the Universe Ends. Just as Robert Frost imagined two possible fates for the Earth in his poem, cosmologists envision two possible fates for the universe: The evolution of the universe is determined by a struggle between the momentum of expansion and the pull (or push!) All we can truly conclude is that the Universe is much larger than the volume we can directly observe. NASA / "It will be a bit of a sad, lonely, cold place, said Professor Caplan said in a statement. But amid that darkness will be "black dwarfs", the stars that his new work focuses on. The Sun will heat up, swell, boil Earth's oceans, and eventually become a red giant, dying shortly thereafter. Ask a theoretical cosmologist how the universe will end, and one of the first things youll hear is how many options are still on the table. The James Webb Space Telescope can look much farther into deep space, about 13.7 billion light-years away, which means it can look 13.7 billion years back in time. Big Bang, analysis of Credit: NASA/WMAP Science Team, Follow this link to skip to the main content. First, as the end times approach, the beings would need to store a finite amount of energy in the universe; they would then use half this energy to power their thoughts (the only remains of their super-advanced lives). Though those stars would cool down, as they shrink into incredibly dense collections of light elements about the size of the Earth but with the mass of the Sun nuclear reactions would continue. Recent speculation now includes a pervasive growing field of mysterious repulsive phantom energy that rips virtually everything apart. This strange form of matter is also sometimes referred to as the dark energy. But where is our solar system? It is so dominant (about 69 percent the total content of the entire cosmos) that dark energy quickly became a part of any discussions about the final end of the universe. This dark future is known as the Big Freeze. A service of: Start your Independent Premium subscription today. As white dwarfs cool down over the next few trillion years, theyll grow dimmer, eventually freeze solid, and become black dwarf stars that no longer shine.. This is also known as the Big Chill or Big Freeze because the universe will slowly cool as it expands until eventually it is unable to sustain any life. The end state of the universe would be a chilly and everlasting . The final result would be a universe that reaches a tiny singularity, a dark reflection of the Big Bang. NASA / WMAP Science Team During the latter half of the 20th century, cosmologists determined that there were three possible scenarios for the end of the universe, and they all depend on its density. Perhaps our universe was merely one iteration of an infinite string of Big Bangs, Crunches and Bounces. No one knows if the universe is infinitely large, or even if ours is the only universe that exists. Understanding such details is crucial if we want to figure out whether were heading for the Big Freeze or something else. The first of these black dwarf supernovae is predicted to occur in about 10 to the 1100th years, a length that read out would mean saying "trillion" nearly 100 times. Eventually these bubbles can run into each other, and from our viewpoint it would be like our universe collided with another universe.. <p>A firestorm of star birth is lighting up one end of . But heres a question they havent figured out yet: Hows it all going to end? Please try again later{{ /verifyErrors }}, Mystic Mountain, a pillar of gas and dust standing at three-light-years tall, bursting with jets of gas from fledgling stars buried within, was captured by Nasa's Hubble Space Telescope in February 2010, The first ever selfie taken on an alien planet, captured by Nasa's Curiosity Rover in the early days of its mission to explore Mars in 2012, Death of a star: This image from Nasa's Chandra X-ray telescope shows the supernova of Tycho, a star in our Milky Way galaxy, Arrokoth, the most distant object ever explored, pictured here on 1 January 2019 by a camera on Nasa's New Horizons spaceraft at a distance of 4.1 billion miles from Earth, An image of the Large Magellanic Cloud galaxy seen in infrared light by the Herschel Space Observatory in January 2012. Approximately 24% of this is in the form of a low pressure matter, most of which is thought to be non-baryonic dark matter, while the remaining 71% is thought to be in the form of a negative pressure dark energy, like the cosmological constant. Up to 200 billion. Unlike gravity which works to slow the expansion down, dark energy works to speed the expansion up. Previous. expansive internal force. increased understanding of the nature of Robert Nemiroff Within this overall structure, the interplay of atoms and light with the mysterious dark matter and dark energy . By time the Universe is around 10 23 years old, that process should be pretty much complete. Of course, theres always the chance that dark energy wont actually matter. In 2003, Robert Caldwell of Dartmouth College proposed a new theory of the expansion of the universe where the rate of acceleration keeps increasing over time. Eventually, theyd use up their available energy and return to stasis, with more energy in reserve. The Dyson Scenario:One important question concerning the ultimate fate of the universe concerns its inhabitants: Can intelligence and consciousness overcome entropy, the eventual wearing down of our universe? Sign up for our email newsletter for the latest science news, Want More? But with the emergence of dark energy, a few of the previous contenders for our ultimate fate are now much less likely.
