This question may have been posed here before. If so, it was before my time.

I'm just wondering if any of you ever ask yourselves: Does the Universe have an end, like an outer wall? Of course we know that is a paradox and seemingly impossible to answer because what is beyond the outer wall?

Do these type of questions fascinate you, bore you, trouble you ?

Will the universe continue to expand forever? Or will it implode and go into some kind of reverse cycle and then start over again... and keep cycling in and out?

I wrote a poem about this concept once -- a sonnet called 'Bang-Bang'. I don't know if I still have it on my hard drive or printed out somewhere.

To be honest, we won't know till we get there. Since that will probably be in the way distant future I see no reason to worry about it.

Interesting subject though!

The collapse upon itself theory is called the "Big Crunch", and though it's not completely out of the question, mainstream science thinks we're facing, instead, a "Big Freeze". Essentially, the thinking is that the universe will continue to expand until everything rips apart and there is, literally, nothingness existing at (or near) absolute zero.

Regardless, it's farther in the future than the big bang is in the past.

Thanks for the link, DentalFloss. I look forward to checking it out.

Pamela, I've always been concerned with the possibilities of the future - I was apparently born that way :-) Not that it's particularly healthy for the mind.

Heartsong,

Here is a recent program that aired on NOVA. This specific episode is on what we currently have learned about the expansion of the universe and its ultimate fate.

NOVA | The Fabric of the Cosmos


The topic is 45 minutes into the video. Just move your cursor to 45 minutes along the slider at the bottom of the video frame, at "chapter 5 - the expanding university." But if you can make the time, this is a great series to watch.

Me too.

In order to save what little sanity I have left after raising 5 kids, I try to limit such things to what may happen in my lifetime though.

I have wondered on many occasions if the Universe had an end and if it does, what's on the other side? I personally don't think that it has an end, it's never-ending and there's so much we don't know about it. Maybe someday but right now all we can do is sit and wonder and marvel at it's vastness and hope that it doesn't implode anytime soon.

I like the "new" idea that part of our universe can "bubble" up and form a whole new universe.

Then, too, since we don't know a whloe lot about black holes, there is the fascinating idea that we are in a black hole, and black holes are mere entrances to other universes.

Difficult though it is to comprehend, the Universe at its outer limit doesn't end in a wall, and there is no vacant space on the other side. There is no other side. To say there is nothing there is misleading. Space-time simply ends. There is no 'there'.
