What will happen at the end of the universe ?

The Big Bang may have brought the universe into existence, but will a similar event bring about its demise?
There is so much we don't understand about the universe and the nature of existence that even attempting to comprehend how anything actually exists at all is enough to make your head hurt.

As things stand, most scientists adhere to the theory that the universe started with the Big Bang, but what exactly is likely to happen in the far future ? Will the universe end as quickly as it began ?

It's a topic that is explored in detail in cosmologist Katie Mack's new book 'The End of Everything.'

The most widely supported theory for the end of the universe is that it will suffer 'heat death', which basically means it will continue to expand and cool until everything decays and fades away - a process that is likely to take trillions and trillions of years.
Another, more 'out there' possibility is that the universe will suffer a more rapid fate through a theoretical process known as 'vacuum decay'.

"You tweak something in the equations and then you find out that it's possible for a sort of bubble of death to materialize somewhere in the universe and just expand out at the speed of light and destroy everything," said Mack.

"The only thing that makes people doubt that it could happen is that it's in that realm where we can't test any of the theory, so we don't know if something changes about the theory in this higher energy situation."

"It's probably not going to happen in the next, you know, trillions and trillions and trillions and trillions of years and so on. But, technically, it could happen at any time."

Whatever the case however, the end of the universe isn't something anyone alive today (or even the human race in general) will likely need to be worrying about.

What part of: are you failing to understand.  Continuing to make provably false claims is making you look more dishonest with every post you make.

Who is he? What are his qualifications? Is his opinion backed up by real science? Where does he actually say it's going to happen soon? He appears to be a blogger, not a scientist. He appears to make pseudoscientific claims rather than using genuine science. Despite that NOWHERE does he seem to say that the end of the universe is imminent.  Using the claims of people that are not experts in the field and using them to back a claim is known as "appeal to false authority". It is a logical fallacy and, therefore not a legitimate argument. See here: [More]

@Damien99Here is an idea for you. The author interviewed for the article has written a book. I have bought a copy. Instead of continuing to lie about what she says why don't you buy the book and actually learn something.  Even if you don't learn something, the time you take to read the book may keep you away from a computer and stop you making a fool of yourself for a while.

Well, our Sun, and therefore--out Solar System will be around for about 5 billion more years.  With this in mind--the universe will still be here when our home is long gone.  But, will the universe keep expanding and then it's energy will fizzle out, or will it then proceed to collapse,and take 20 billion years to collapse?   . . .  Another option--some high advance life will split the God particle(not the Higgs) which will destroy the universe?

Our universe is held within a 4 dimensional sphere on some kids shelf. Just waiting for the great feline to knock it off.

We think is held within a 4 dimensional sphere, but like always, we are damn wrong and know nothing like the amoeba we are. Just waiting for anything that we don't comprehend to knock it off.
