The theoretical physicists believe that the universe could end one day – and this process may have begun.
Ente may have never heard about several theories about the end that will be presented below. One of the most interesting things about the universe is, we knew very little about the nature of this. And just as we want to know what happens after we die, science and science is also asking the question, “How Judgement happen?” There are several theories about this, which is very different from one another.
What kind of theories about the end of the universe? See the following reviews :
1. THE BIG CRUNCH
The universe is believed to be originated from a great explosion called the Big Bang about 13.7 billion years ago. How does the universe end? What science does know is called the apocalypse?
There is one theory that was developed to describe the fate of the universe. One of them is called the Big Crunch. According to the theory, the universe will end up being highly incompressible unity. The situation may be called Resurrection.
Based on the theory of the Big Crunch, the universe will expand as a consequence of the Big Bang. However, the development will not continue to happen. At some point, the universe will stop expanding and shrinking. All will be drawn up only the largest remaining black holes.
To be able to justify this theory, some of the characteristics of the universe needs to be explained. One of them is the density of the universe. There must be a so-called critical density to explain that the universe can be compressed again after it expands.
Initially, scientists say, the Big Crunch may occur. Illustration like gif image at the top, like a ball thrown up and at some point will stop and fall. Similarly, the universe, gravity will win and draw all the objects in the end.
Until now scientists have discovered that the universe is constantly expanding. There is a dark energy that makes the universe expands and the object away. Big Crunch theory began to falter. The possibility of a small universe would die.
Researchers are still seeking to know and predict the fate of the universe in the end. Science has not found a definitive answer. Big Crunch is just one theory. There are still other theories, such as the Big Rip and Big Bounce.
If the universe is going to die, prediction, time is still about 100 trillion years into the future. At that time, the last star will be extinguished. The new star birth is not possible. The universe becomes very dark and cold.
2. THE BIG BOUNCE
When Buddhism recognize reincarnation, as well as astronomy and cosmology. One theory in cosmology is the Big Bounce that outlines that there is no universal apocalypse or the end of the period. There was only reincarnation. Big Bounce is also sometimes matched with the Big Bang theory of creation of the universe.
Big Bounce associated with the Big Bang theory or the birth of the universe 13.7 billion years ago and the Big Crunch theory which describes that one day the universe will stop expanding and shrinking up into a single unit.
According to the theory of the Big Bounce, Big Bang and Big Crunch is a process life cycle of the universe in the form. Universe created through the Big Bang, expand, shrink, die in the form of the Big Crunch to finally be reborn through the Big Bang. Big Crunch will always followed the Big Bang.
Truth Big Bounce is highly dependent on the presence or absence of the Big Crunch. While the Big Crunch itself requires higher density values than a certain value, or so-called critical density. Without it, the Big Crunch will not happen.
So far, research indicates that dark matter makes the universe continues to expand. Style because of the gravity of dark matter predicted defeat made all the objects of the universe is interested in the Big Crunch.
Thus, it is still difficult to believe in the existence of the Big Bounce, universes are reincarnated. Big Bounce is just one theory that describes the fate of the universe, there is still another theory, the Big Crunch as well as the Big Rip.
Will humans be able to prove whether or not the Big Bounce. The only way is to experience it. Five billion years, the Sun will become a red giant, making life on Earth disappeared. Humans will not have Big Bounce but can survive the apocalypse Earth and live up to trillions of years to come.
3. THE BIG FREEZE
There are scenarios end of the universe is called the Big Freeze. This scenario, sometimes also called the Heat Death or death of thermal energy. In this theory material will gradually decay into radiation as the universe continues to expand. After trillions of years, even the atoms that make up the remaining material will begin to degrade and disintegration.
The stars will age and disintegrate, the black hole will evaporate and eventually even light particles will disappear.
apocalypse occurs as a consequence of the expansion of the universe because the process indefinitely. The term Heat Death, which is another name for this theory comes from the idea that in an isolated system, the entropy, or simply related to energy per unit temperature will continue to rise until it reaches the maximum value.
At the time of reaching maximum entropy, the heat will be distributed evenly across a very wide area, do not allow any space that allows the use of energy. At that time, the mechanical motion into a system would be impossible. Scenario end of the Big Freeze opposite to the Big Crunch. In the Big Crunch, the universe would be greatly compressed, forming a very large black hole. Meanwhile, in the Big Freeze, the universe becomes very dark and cold.
To determine which scenario is more likely, scientists need to collect data on density, composition, and even the shape of the universe. There are so-called critical density. If the density values were found to be lower, Big Freeze scenarios become possible. So far, measurements by the Wilkinson Microwave Anisotropy Probe (WMAP), which captures the Cosmic Microwave Background Radiation (CMBR) indicates that the density is much smaller than the critical density. Thus, scientists say, the Big Freeze is a universal doomsday scenario is most likely. When did it happen? Still trillions of years.
4. THE BIG RIP
According to the scenario of ‘big rip’, the universe will continue to expand and the rate of development is getting faster every day. Dr Mat Pier on Portmouth University explained that the expansion or expansion of the universe when it was young was slowed by the influence of gravity. However, within the past 5 billion years, the universe begins to expand very quickly due to the mysterious force scientists call “dark energy”.
Eventually, the universe is predicted to swell uncontrollably at a rate equal the speed of light. Impact, galaxies, stars, planets seemed to shreds nothing left to perish.
5. VACCUM METASTABILLITY EVENT
One theory about the end of this explains the idea that the universe exists in a state, which is fundamentally unstable. If ente regard to the value of the particle quantum physics, some people say that our universe was “berjungkat-totter” stability tip. So, some scientists theorize that billions of years from now, the universe will “fall over the edge.” When this happens, somewhere in the universe, a bubble will appear. After that, the bubble will inflate in the speed of light and destroy everything it touches.
But do not worry: the universe still there. This is the universe bubble “similar but not the same.” The laws of physics will change, and perhaps the life cycle itself.
6. THE TIME BARRIER
If we try to calculate the probabilities in a multiverse, we will find the same problem as the universe with infinite time: All things have a 100 percent chance to happen. To overcome this, the scientists used a small part of the universe to calculate the probability that will occur therein. This makes the calculation is done successfully, but the restrictions which they have always cut the universe at the outer edge of a small part of the universe taken as a sample. So, you may cut the top end of Borneo if you draw a circle in the midst of a map of Indonesia.
Because the laws of physics are fabricated in an infinite multiverse, the only way to make the laws of physics makes sense that if the restriction is true, the physical constraints could become more widespread. So, based on physics, the theory about the end of this explains that the sector in time, after 3.7 billion years, we will go beyond the time limit, and that is where the end will occur.
Multiverse theory is the apocalypse did not happen at all. Because the universe is innumerable, and all of the universe is possible into or out of existence. Thus, in another universe the Big Bang might be happening now, and the universe we may end up with a Big Crunch. But it did not matter, because in the multiverse, our universe is one of the universe of universes is not limited in number, and there are still “universe” bigger out there. The universe is everything, whatever it is that manifests itself.
Though time itself can be discharged in another universe, the multiverse theory, a new universe was formed at all times. Based on the physics, the number of new universe will always be greater than the old universe. So in theory, the amount of the universe is increasing.
8. THE ETERNAL UNIVERSE
And the last is the eternal universe One theory about the end, which is always echoed since ancient times. This concept is one of the concepts first created man on the nature of nature, but there is nothing new in this theory a little more serious.
Instead of the start time in line with the Big Bang, time itself might have been there before, and the Big Bang could have terhadi as a result of the collision of two branes (a kind of blanket structures that exist in outer space, which is a higher form of existence). In this theory, the universe was formed a kind of cycle, and will continue to expand forever.
We can know this for certain in the next 20 years. Scientists have launched the Planck satellite which conducted the survey universe for the radiation pattern, to predict the universe theory which one is true. It is quite long, but once humans know the existing radiation pattern, we can further understand how the universe began and how eventually.
