A cool vid in regards to our current knowledge & theories of the life and end of the universe that I feel fits this topic
https://youtu.be/uD4izuDMUQA
I'm not sure if there are any huge issues with the vid but everything in it sounds plausible (or as plausible as our understanding of it could be currently).

I beleive it is NDT or Lawrence Krauss that has a segment talking about how billions of years into the future we won't even be able to see the lights of other stars as everything continuously expands. Everything is distend to be dark, cold and silent.
All the while... entropy
All the while... entropy
What if there is a universal wall? Like a maximum expanse. And the stars collide with it and stop.
That's the mystery of it all, what is beyond the universe? What was there before the Big Bang?
It just means the IF we were to become an interstellar species someday we are hard locked into Milky Way and thats about it.
Unless we find some what to make worm holes to instantly port to other galaxies the Milky Way is the only playground we are going to have.
Lets just hope the supermassive black hole at our center never peters out
No (or, well, who knows, there isn't really a "before the universe"), more space is just continually being created.
Technically yes, but the timeline for it to matter is so vast that it's not really a problem in any real sense.
Was going to post this exact video. Pretty great watch. Amazing how far the symphony of science channel has come in the past few years, also. Melodysheep is genius.
No. Not in our universe at least. Think of it like blowing a gum bubble. Time and space (as we know them) only exist inside that bubble, and the rate that the bubble is growing is faster than we'd ever be able to catch up to, even at the speed of light.
As I understand it, no. Both were created by the universe. The universe is space and time. As the universe expands, so does space and time.
Isn't time a human word for describing entropy, since time isn't one of the fundamental forces
Are we being pushed apart by momentum from the big bang or Dark Matter expanding?
Could that same dark matter also contract at some point bringing us all closer together again? Like a balloon inflating and deflating infinitely over aeons (ok am i describing infinity theory here or not I cant remember)

Maybe I am not thinking this out. So there is nothing, but as the universe goes it creates somthing. Like if i leave the boundary of the universe I would cease to exist because there are no rules there that says I can exist?
What does it mean to you that the universe is expanding 9% faster? This percentage is meaningless to me :/
Space is expanding into more space. The gravitational attraction of galaxies mean that it is only observable in the relative movement of galaxies in comparison to our own.
The water in your example is not expanding. More water is being added. The water would be expanding if it were heated up. However neither that nor any other expansion you would observe in everyday life is analogous to the expansion of the universe. The wikipedia page on the expansion of the universe might help but if you want a proper explanation you have to learn General Relativity (and the mathematics underpinning it).
The water is not expanding in the glass... You're simply adding more molecules of water into the glass. Same principle as if you were adding sand instead of water.
This is different, because it isn't only a question of adding more matter in the universe... But I'm not that knowledgeable in the topic, and so I will leave it there.
It's a scientific discovery. Surely you can't be so focused on yourself that you're only interested in things that directly and immediately impact you personally?
It's not expanding into anything, there is no "outside" the universe. The expansion means that the space between particles in the universe is increasing. It can't be compared to a balloon blowing up where the expansion of the balloon displaces the air outside because unlike the balloon there isn't an edge where the universe stops and another medium begins.
I like that one
Having the Universe infinitely cycle itself in and out helps me reconscile the crazyness of it all
We can't reach any other galaxies at the moment, local or non local. We can barely leave the solar system using probes, and it takes us many years to do that.
it actually triggers me even more.
because if it is a cycle... it duplicates itself or it is all brand new again? @_@ how many times have we had this conversation.
like 4000000 millions years ago
I think we'll actually become an interstellar species given the rate our technology is expanding.
Naw everything is created and then destroyed... and then big bang again?
This guy gets it
