[QUOTE=Xakoro;40729696]So there are (probably) multiple universes... and gravity can travel between them?[/QUOTE]
That is probably one of the more interesting implications. If there are other universes, what is in the void between them? And how (and why) can gravity permeate it? Why not other forces? Almost makes me want to become an astrophysicist.

Good luck, there's a good chance there's an infinite number of them.

Given an infinite number of universes, there is at least one where you are the Hulk. Enjoy.

That is one of the more interesting implications (lets assume that there actually are other universes). Gravity is pretty baffling even in our universe (Higgs field was probably a good step forward though), but if it could affect things from different universes, that'd be something. If there is nothing in between (not even space and time maybe?) how would gravity "cross" that?
This is philosophy though, not physics. Pure thought-based ideas and conjectures with very little observations.

Not even a little.
There is a universe out there with a planet of pirates. And on that planet it's legal to share any kind of files, no one cares because they're all pirates!
Okay so how could other universes influence our own?
I don't think infinite universes would necessarily mean everything you could imagine is possible if there's no combination of initial conditions that would lead to that universe.

This is a tiny bit of evidence for a very big claim.[/QUOTE]
You're not going to get much more evidence than this, by definition its not going to be possible to observe potential outlying universes, as the speed their space would move away from us is far faster than the speed of light. Really the only observation you can get is to infer their existance by the effect they have on our surroundings.
[QUOTE=Mingebox;40731075]I don't think infinite universes would necessarily mean everything you could imagine is possible if there's no combination of initial conditions that would lead to that universe.[/QUOTE]What if universes are being generated on the fly by various imaginations throughout the universes? So if you imagine a universe where everyone loves the flavor of semen on top of pizza, your semen pizza chef alternate could imagine a universe where it isn't, etc. What if this universe didn't exist up until that happened? All of our memories, the ice age, dinosaurs, big bang... All of that happened because one semen chef thought it up. Or maybe both of these universes were imagined by my brony alternate self, but that universe was imagined up by a pornstar Gabe Newell. D:
I think I need to stop smoking crack.
I will laugh if it just turns out to be a particle of dust on the lens of the telescope.
[QUOTE=hypno-toad;40731305]You're not going to get much more evidence than this, by definition its not going to be possible to observe potential outlying universes,[/QUOTE]
I don't see how that is the case. Observing their effects is equivalent to observing their existence, or at least observing that SOMETHING is happening which we haven't fully explained.
[QUOTE=hypno-toad;40731305]as the speed their space would move away from us is far faster than the speed of light.[/QUOTE]
[citation needed]
I'm not sure the "speed of light" even has much meaning when you're talking about distance between universes. These are not other patches of stars inside our spacetime, but completely different spacetime manifolds from ours.
[QUOTE=hypno-toad;40731305]Really the only observation you can get is to infer their existance by the effect they have on our surroundings.[/QUOTE]
Sure. That's already what I was talking about. But it doesn't matter. Just because you're not likely to get much better evidence any time soon doesn't mean that you can just shout "OMG OTHER UNIVERSES" because you see a thing that could maybe be caused by them. You have to develop a working model which can make observable predictions and test them with a high degree of accuracy.

I think that the common perception that in an infinite number of universes there must be so many extravagant possibilities is fairly inaccurate. Realistically these universes are most likely near mirrors of our own if not identical. You can make an infinite number of peanut butter and jelly sandwiches and even though they might never spread exactly the same, it's still a PB and J sandwich. Hitler still lost WWII and 9/11 happened. Hopping across universes doesn't land you in a utopian wonderland or an orwellian hell hole, it lands you right in the same old place we've always been.
The only reason I see that another Earth should be so different is by human choice, and it's kind of hard to state that a human will act the same way every time. 1+1=2 always, but humans aren't mathematical, rather chaotic with a very slight underlying order. Unless humans are equally as simple as atoms bonding simply on some basic principle, that humans are merely driven by glorified instinct.

Half-Life 3 spoilers- We ARE the Combine.
If this ends up being true it will be the single most important discovery in human history. It will unravel all concepts of religion (or at least cause them to be re-written)
This is some deep shit
can an actual science person explain what infinite universes would mean and what they would be like
[QUOTE=Blockhead;40731485]I will laugh if it just turns out to be a particle of dust on the lens of the telescope.[/QUOTE]
Reminds me of that big potential discovery where some some scientist detected "pixels" on some ray of radiation. But then it turned out that the pixels where the result of the limitations on the machine they where using.
You would think they would check for those things

This is a joke right? Nobody knows.
[QUOTE=Sprockethead;40726442]Were not talking alternate universes.
Were talking universes with different laws of nature.[/QUOTE]
What says their physical laws are any different than our own? There's really nothing to suggest that at all.

dont see how it would have any religious ramifications at all, no religious text refers to the universe as we understand it now; it could've just been a blanket term for anything and everything, which in the case of the discovery of multiple universes would simply include those as well

There's not much suggesting anything

But almost everything. In an infinite multiverse, literally anything with any positive probability of existing [I]has[/I] to exist. Obviously to have a positive probability, it needs to obey the laws of physics (presumably). But even then, in an infinite multiverse, things will exist that are as close as possible to things that disobey the laws of physics whilst still obeying them.
[QUOTE=BusterBluth;40733167]There's not much suggesting anything[/QUOTE]
It would be more logical to lean slightly more towards the physical laws of other universes being similar or the same as ours though than automatically assuming they'll be different though.
But yes, you're right. There's only slight evidence that suggests they even exist and there's a good chance that maybe something within our own universe that we're not aware of yet could explain their evidence just as well too.
[editline]21st May 2013[/editline]
I think one thing people should probably keep in mind when thinking about other universes is that things tend to follow the easiest path. So unless there's some sort of physical force or something that differs in another universe for some reason, it would end up being more or less the same as ours.

I'm not disagreeing on that point. More of saying that articles like these are comprised of a whole lot of nothing.
so somewhere there's a universe where everyone is a furry and people who cap to human porn are flamed?
also there could be a star trek universe that is actively at war with the star wars universe
What if each of our eyes sees into a different universe, but the two we see are near exact copies.
