Decomposed > You ask if the universe might fall into a singularity.


Ummmm . . . Probably poorly written.
Not the Universe collapsing into a black hole - just ALL the matter in a particular 'small' portion of the universe.

I see the universe as having no 'end'. As in no matter how far one goes - there is still more 'universe' one could continue to travel on through.

So, take all the stars and other matter we might be able to see or detect . . . and it is still a fraction the size and amount of matter in the 'whole universe'. But give it a trillion years or more and most of what we can detect (some will manage to escape to other parts of the 'universe'). And some from the 'rest of the universe' manages to get in 'our universe' and, eventually, all the stuff we can detect collapses back into one 'black hole' - or a 'singularity'. Which, when it finally absorbs a 'bite' too much causes it to explode in a 'Big Bang' sort of Super Duper Nova unleashing all the ingredients necessary to make a new 'universe' (Or rather a collection of matter and energy which, some 14 billion years later, might induce an intelligent species to conclude was the entirety of 'their universe'.)

Re: “Any chance that, in reality, within a given region of space (greater than the size of our presumed universe) all the matter will eventually collapse into a super dense black hole . . . which will then 'explode' like a super duper nova - providing evidence of a 'Big Bang'. And repeat several Trillions of years later?”Your supposition is in line with something I read a few years ago which went like this:

The Big Bang can be thought of as a rubber ball on a space-time staircase, inflating as its potential-energy gets released. The small, hot, high-potential energy universe fell from the step on which it was born, down to the next, lower-potential energy step. That fall must have been quite a drop since it is the inflationary period physicists are now investigating, a period in which the universe grew to an appreciable portion of its current size in just a few seconds. Vast amounts of new energy, matter and expansion were unleashed. Since then, the universe has continued expanding and cooling but at the slower pace its ledge and entropy allows. For more than 14 billion years, the universe has existed in relative harmony on that flat piece of space-time.

What the theory can't say is whether the flat space time on which the universe resides is at the bottom of the staircase or if it is on the flat part of one of the steps, moving inexorably toward another inflationary drop.

You ask if the universe might fall into a singularity. By this theory, I think the answer would be 'no' - but only because the approaching precipice doesn't meet the definition of 'singularity.' The universe could drift off of its current safe haven, falling to a still lower potential energy state and, in the process, be ripped asunder yet again.

In case you're wondering, this is called the 'ribit on a stairwell' theory. Is he at the bottom? Or will he keep falling? Nobody knows.
