Journey To The End|Scientists divulged a true heartbreaking picture of the universe just like it has comes to its end. Nobody wants the end of something, 'RIGHT'. But nevertheless, everyone has to go one or the other day. Our universe has existed for nearly 14 billion years and people are concerned that it should continue to exist for billions of years more.
According to the last and final paper from the legend physicist Stephen Hawking, detailing his last theory on the origin of the universe predicts that the time itself will end in just 5 billion years- coincidentally, by this time our sun is also slated to die.
This prediction has come from the theory of eternal inflation, which says that some bubbles in the universe have stopped inflating leading to dead space, while some of them never stopped inflating because of quantum effects leading to an infinite number of the multiverse. Our universe is a part of the multiverse. Everything we see in our observable universe is contained in one of these bubbles which has stopped inflating; allowing for the formation of stars and galaxies.
The only problem with a multiverse is that anything that is impossible will happen and must happen, weirdly, an infinite number of times and that makes calculating probabilities - such as the odds that earth-size planets are common - it's just Impossibly impossible.
In this multiverse where there is an unending number of worlds, so this is deeply troubling for calculating probabilities and knowing what physics we can expect to observe. Probabilities are relative. It’s all about how likely one outcome is to occur in comparison to another. But if both outcomes have an infinite chance of happening, it would make calculating any probability pointless.
It's the actual reason for emerging the geometric cutoff— a point after which time no longer exists. This means the number of events would be reduced to a finite amount and the relativity of probabilities again makes sense.

The mathematical cutoffs take a once gargantuan and infinite universe and make it into a limited space where some events can happen.
In fact, many physicists expect that eternal inflation is a natural extension of the theory of inflation, which solved some of the problems with the original big bang theory.
According to early models of the big bang, groups of matter that are now on opposite ends of distant reaches of the universe are too far apart to have ever been in contact with each other. That means the early universe should have been clumpy.
What's more, at the rate our universe is now expanding, its overall shape should have curved over time. Also, the initial moment of creation should have filled the universe with heavy, stable particles called magnetic monopoles.
But observations in the past few years of radiation leftover from the big bang say otherwise: The early universe was uniform, the shape of the current universe is flat, and magnetic monopoles have never been conclusively observed.
Standard inflation theory accounts for all this by saying the universe experienced a period of extremely rapid expansion in its first few moments, eventually leveling off to create the flat, uniform universe we see today.
"A good analogy would be that our theories predict a boiling pot of water, and the origin of our universe is the formation of one of the bubbles at the bottom of the pot. The theory strongly suggests the existence of other bubbles, because when you boil water, you never get just one bubble."
Nobody knows why [eternal inflation] should be wrong, but nobody knows exactly why time should come to an end either.
Inflation aside, there are many theories in physics for how the cosmos might end. In a "big crunch," for example, the universe would reverse its current expansion and shrink into a black hole.
Then there's the "heat death" theory, in which the universe expands forever until it reaches a state of thermal equilibrium, in which nothing can happen.
Yet another idea is called the big rip, in which the accelerated expansion of the universe eventually rips all matter apart, atom by atom.
If the theory of eternal inflation is correct, then even when our universe ceases to be, the larger multiverse will continue.
No matter which scenario sounds most plausible, there's no need to go off and sell your stocks because the universe is going to end in five billion years.
There is a huge journey left for reaching the time meanwhile, we can get the actual story the universe afterward.
