The universe is where our home is located, everything that ever existed every civilizations that has risen and also fallen all existed within the universe.
Like every thing has a beginning and also an ending. Our universe came into existence 13.5billion years ago and since then it has evolved over time to become the universe we see today.
Our universe is a violent region where creation and destruction are taking place every day,from the birth of a star, to the death of a star, to a Blackhole swallowing an entire Star, to region of intense activity that not even life can exist.
Among all odds life existed in our solar systems a miracle some people do call it.
Well just as life always come to end, our universe is not excluded from these universal law of nature, everything that has a beginning in time will surely end.
From the steady state theory which believe that our universe was not expanding bit it was static, to the current big bang theory which explained that the universe we live him was expanding rapidly.
End of the universe
According to physics and astronomy, the end of the universe will be determined by 3 things
Gravity force, dark energy , and the matter density of the universe.
Gravity:
Gravity is the force of attraction between two bodies, since gravity act on everything that has mass, so the force of gravity is active every in the universe.
Dark energy: above I told you about Scientist later discovery that the universe was expanding rapidly and it is not slowing down at all, the energy which is believed responsible for these expansion is called dark energy, they call it dark because we don't know much about it.
Matter: for centuries we always believed that matters is anything that has mass and can occupy space. Well in later years Scientist finally came to realised that the matter that made up human body and the visible universe only comprises of 5% of the total matter that made up the universe, and the most dominat matter in the universe was actually a hidden form of matter called Dark matter. These force of matter could not be detected by our equipment, but Scientist measure the Dark matter by the way it interact with gravity.
How the universe might end!!
The above 3factors mentioned above are the three things that we determined how our universe will end. There are three possibility depending on how those three factor interact with each other.
Big crush:
The hypothesis is a symmetric view of the ultimate fate of the universe. Just as the Big Bang started as a cosmological expansion, this theory assumes that the average density of the universe will be enough to stop its expansion and begin contracting. The end 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.
Big Rip: these second hypothesis is believed that if the universe keeps expanding rapidly, Dark energy may over power gravitational force on a small scale, and these could lead to dark energy ripping stars apart.
Heat death(big chill): As the universe keep expanding at an accelerating rate, existing stars run out of fuel and cease to shine, the universe will slowly and inexorably grow darker. Eventually blackhole will dominate the universe, which themselves will disappear over time as they emit Hawking radiation. The universe will become cold and everything that is needed to sustain life will no longer exist. The heat death is believed to be a possible candidate since the expansion of the universe could not be slowed down.
Well there are other possibilities which can be found online, but these are the three major candidate that dominate the possible fate of the universe.
Who knows when the end of the universe might be, but the universe is all that we have now. Let us all just enjoy the ride.
Thank you all for reading!!!
