The universe is incomprehensively vast. Nonetheless, some day it will cease to exist as we currently perceive it. The sun will use up all its fuel and die in about 5 billion years or so. At that time the solar system will no longer be habitable. Will humans be around at that time? No one knows.
The theory that currently has the most support in explaining what we think will end the universe is one called "The Big Freeze". The big freeze theory claims that the universe will continue to expand until it reaches nearly absolute zero and all things cease to move. This is supposed to happen in about 10100 years. For comparison the universe is currently 13.7 Billion years old (13,700,000,000) where as the big freeze would happen in approximately 10100 (100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000) years, and the entire history of the human race is a mere 200,000 years.
It is important to note that even if/when the big freeze occurred, the universe would still exist. it would merely be lifeless and void of all movement. Also, because matter and energy are nearly synonymous as far as physics is concerned (E=mc^2), there would still be movement on a super-subatomic level. The most recent theory regarding this being the string theory, but back to the main question.
It is possible to theorize that since the universe has a defined beginning, as calculated by Stephen Hawking, that it could have a legitimate end as well. speaking purely philosophically, it would seem that a finite universe, which has a beginning, may necessarily have an end that we do not know; the other theory would be that the universe could cease to exist upon the same grounds, which brought it into existence. I speak philosophically here because physics cannot be used to define knowledge of events that took place outside of our universe and thus outside of our laws and confines of natural science
Answer: No, the universe is Bounded, no beginning or end.
The Universe will change not cease to exist.
Answer: Although the Universe has a clear beginning (with the Big Bang), it seems it won't have a clearly-defined end - it will just continue expanding. However, a time will come when it won't be able to support any type of life, because of the Second Law of Thermodynamics. In other words, all useful energy will have been used up.
No, the universe does not have an end. Many people believe that there are many universes in something called the Universe of Universes. When we look at telescopes we see a green blanket at the end of 4 trillion light years and can see nothing past it. This is because it would have taken light 4 trillion years to reach us and we cannot see it.
actually it might have cause everything has an end............this question is very puzzling, dson't strain your brain
just ;,v;l,gafld
Whether Universe has an end depens on whether it has enough Mass or not. The current view is that looking at the remnants of Big Bang the 3 Deg K radiation and its granularity it is Flat and Open Universe.
It is currently believed that it will continue expanding forever. That means there is no specific ending date, but a time will come when there is no more available energy, which is required to sustain life. For more reading, do a search on "heat death of the Universe", for example on the Wikipedia.
No, dark energy does not exist, it is a misunderstanding of the workings of the Universe. What is called dark Energy is the vector energy of motion, mcV,
missing from theories. Newton's Gravity Theory is based on E=-mu
/r which neglects the vector kinetic energy mcV.
It is as if Newton assumed that the earth was not moving under the gravity of the sun., but the earth is moving. And the energy of motion is mcV.
Einstein understood that gravity as Newton saw it should have collapsed the universe, but the universe had not collapsed, so Einstein added a cosmological constant to account for the lack of collapse. The cosmological constant is a form of Dark energy.
The common sense answer is there is vector kinetic energy that provides a centrifugal (outward) force that balances the inward centripetal force of gravitational potential energy, with the centrifugal force from kinetic energy. Kinetic energy (Dark energy) is a sign of a closed stationary, never ending, universe.
Excellent question. Too bad we don't have a clue.
Scientists are divided on the topic, and everybody has great mathematical reasons why their answer is correct. But the answers are all different.
My take on this is, it's 50/50; either it will, or it won't.
We honestly have no idea yet. There are some theories that suggest that the universe will continue to expand forever, with all the galaxies flying apart as the stars fade out until everything is cold and dark.
Other theories suggest an "oscillating" universe, one that expands and contracts. In this framework, the "Big Bang" is the transition between cycles, to be followed some unknown number of billions of years from now with a "big crunch" as all the galaxies and stars fall together into an incredibly dense cosmic mass containing all possible matter - which then might explode in another Big Bang, to begin the cycle anew.
Scientists currently do not believe that there is enough mass in the universe to halt and reverse the expansion. But other theories suggest that undiscovered but suspected "dark matter" might make up 95% of all matter, thus providing enough (?) mass to close the cycle.
Ask your question again in another 50 years or so; perhaps we'll have started to find a few hints by then.
EVERYTHING comes to an end; but we don't know what kind of end it will be, or when.
Not as we know but there are theories, many galaxies exist within the universe. Different solar systems black holes ect.
Dark energy. The current estimates for the distribution of mass/energy in the Universe are approximately: 68% dark energy 27% dark matter 5% baryonic (i.e. "normal") matter
Dark energy.
There are several pieces of evidence for dark matter. For example: * Our galaxy, and many other galaxies, rotate way too fast for the amount of known matter. * Evidence from gravitational lensing.
Dark Universe - film - was created in 1993.
No. It's generally believed that the universe has insufficient mass density to slow or halt its expansion (and in fact, there's some evidence that the rate of expansion is actually increasing due to "dark energy", which is a slightly more academically acceptable way of saying "we don't know what").Excellent answer!The Universe (our universe) will probably end in a «Big RIP» or a «Big Freeze» scenario, after the «Dark Era and Photon Age», about 10100 years from now.Please rememer that after the «Dark Era» age, what happens after this is speculative.There could even occur a new «Big Bang», supereons after the «Dark Era».Or else the «String Theory» is correct, and our universe is a «membane», or «Brane», and may collide with another «brane» sooner, creating a new universe, God nows what type of universe would be created...
Dark energy -- whatever it turns out to be -- constitutes about 74% of the energy in our Universe.
Yes. Dark energy is responsible for the expansion of the universe.
Yes. Due to dark energy, the Universe is expanding faster and faster.

No. What is killing the Universe is the Second Law of Thermodynamics.
Dark energy is the force that is driving the expansion of the universe
The mysterious substance which is believed to accelerate the Universe's expansion. Look up "dark energy" on Wikipedia for more details.
there are the energy that mostly makes up this universe and its had been here since the beginning of the universe and also they are invisible.
The one where the universe is expanding and accelerating.
Current theory states that it's "dark energy".
Dark energy is the term to refer to the force that is causing an expansion of the universe to accelerate. It is estimated that the universe is 68.3 percent dark energy, 26.8 percent dark matter, and 4.9 percent ordinary matter.
