The Big FreezeBig FreezeMost observations suggest that the expansion of the universe will continue forever. The prevailing theory is that the universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future scenario once popularly called “Heat Death” is now known as the “Big Chill” or “Big Freeze”.https://en.wikipedia.org › Future_of_an_expanding_universeFuture of an expanding universe – Wikipedia. Astronomers once thought the universe could collapse in a Big CrunchBig CrunchThe Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach zero, an event potentially followed by a reformation of the universe starting with another Big …https://en.wikipedia.org › wiki › Big_CrunchBig Crunch – Wikipedia. Now most agree it will end with a Big Freeze. If the expanding universe could not combat the collective inward pull of gravity, it would die in a Big Crunch, like the Big Bangthe Big BangThe chronology of the universe describes the history and future of the universe according to Big Bang cosmology. Research published in 2015 estimates the earliest stages of the universe’s existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.https://en.wikipedia.org › wiki › Chronology_of_the_universeChronology of the universe – Wikipedia played in reverse.
By contrast, cosmologists are less clear how it will all end. One possibility is that the expansion of the universe will continue to accelerate, driven by a mysterious force called dark energy. In that case the expansion will be infinite and forever.
Some 13.8 billion years ago, our universe was born in the Big Bang, and it’s been expanding ever since. Until a few decades ago, it looked like that expansion would eventually end. Astronomers’ measurements suggested there was enough matter in the universe to overcome expansion and reverse the process, triggering a so-called Big Crunch.
After the very last supernova explodes, it’s curtains. Using iron, pycnonuclear science, and a computer, one scientist has scheduled the end of the universe. Today’s bright, showy supernovae are huge stars, leaving small stars to smolder much longer. This research calculates when each size of star will begin to react.
How long until universe ends?
22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = u22121.5.
How long will the universe exist?
The universe will cease to exist around the same time our sun is slated to die, according to new predictions based on the multiverse theory. Our universe has existed for nearly 14 billion years, and as far as most people are concerned, the universe should continue to exist for billions of years more.
What will happen to the universe when it ends?
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
Will the universe expand forever?
A popular theory, introduced by Albert Einstein, is that dark energy is a cosmological constant — an unchanging form of energy that’s woven into the fabric of space-time. If that’s the case, and the force exerted by dark energy can never change, then the universe should continue expanding (and accelerating) forever.
Will the universe last forever?
Most observations suggest that the expansion of the universe will continue forever. The prevailing theory is that the universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future scenario once popularly called “Heat Death” is now known as the “Big Chill” or “Big Freeze”.
Does the universe regenerate?
According to the Big Bang theory, the whole universe emerged during a single moment some 13.7 billion years ago. In the competing theory, our universe generates and regenerates itself in an endless cycle of creation.
What happens after the universe ends?
The result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
Will the universe become empty?
So long as energy exists within it — even the zero-point energy of the quantum vacuum is sufficient — there will always be some form of radiation that can never be removed. The Universe has never been completely empty, and so long as dark energy doesn’t decay entirely away, it never will be, either.
Will there be a second Big Bang?
According to physicists at Harvard, who have a pretty good track record when it comes to stuff like this, the Higgs boson — most often described as a quantum particle that gives other particles their mass — will likely become unstable and explode in a second Big Bang.
Will there be another Big Bang after the Big Crunch?
At the time of the Big Crunch, all the matter in the universe would be crushed into an infinitely hot, infinitely dense singularity similar to the Big Bang. The Big Crunch may be followed by another Big Bang, creating a new universe.
Will the universe end with a bang?
In the unimaginably far future, cold stellar remnants known as black dwarfs will begin to explode in a spectacular series of supernovae, providing the final fireworks of all time. That’s the conclusion of a new study, which posits that the universe will experience one last hurrah before everything goes dark forever.
Will the universe be reborn?
The universe could bounce through its own demise and emerge unscathed. A new “big bounce” model shows how the universe could shrink to a point and grow again, using just the cosmic ingredients we know about now.

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.
