Is the universe infinite?

I can understand thinking you have everything figured out and then someone comes along; asks a question that burst your bubble and your own universe is sent spiraling. But you need to calm down though, it's a friendly discussion.

What are you talking about? Is it something in my explanation that you didn't understand? Did you find the answer inadequate? If so, specify why.

We're talking about the universe. I understand your 'expanding into the future' scenario. I do find it somewhat inadequate. Because you're not certain if the universe is finite or infinite to begin with.

Whether it's infinite or not is irrelevant, according to general relativity -- which makes no postulations of an infinite universe, hence the density parameter relations mentioned earlier -- it's expanding in the direction of time.

The only problem with assigning Ω ≤ 1 is that the sphere anecdote would lose relevance, it wouldn't say anything regarding the direction of the expansion.

Furthermore Ascendancy asked the question in regards to the model of a finite space, hence the use of the sphere anecdote.

Indeed. It's just strange to think that traveling on a linear path, let's assume this time at faster than light speeds, you would still wind up at the same point. It doesn't fit with any "standard" model of thinking about our relation to the things around us. I've only taken Physics I though, so I have yet to delve into anything highly theoretical other than what I have seen on Mechanical Universe, Big Thinkers, Nova, etc, etc, ad nauseum, quid pro quo semper fi.

A fun (though certainly impossible) way of producing an infinite space, it's basically Xeno's paradox enforced through silly physics. You seem to have taken it quite seriously.

Well now you're just acting transcendent.

I was more pointing to your extremely poor phrasing of something you thought sounded clever.

Anyway, no, you can't use Xeno's paradox does not generate infinite space. Xeno's paradox divides a finite distance into infinitely many sections that when added together still converges to the same finite distance. Unless you decide to attribute our universe with characteristics that it doesn't have such as: location based time, it's not going to come together.

No offense, but I don't find stupidity funny.

You mean something based on imaginary physics is going to require some imaginary physics in order to work? Shocking.

You were already proposing spatial dimensions that there is no evidence for.

Wow, you really are taking this too serious.

Do you even know what a spatial dimension is? Do you even know what a dimension is?

this is wonderful

Don't be so hard on yourself.

Astner is obviously really on edge and I don't particularly care about arguing for the sake of arguing so I'm out.

Hah, I've come to see that our universe in fact must be infinite; it impossible to believe that any finite space could contain some of the egos I've witnessed on these forums in my short time here =p

you realize that statement in itself is pure egoism?

Ah, who knew you'd show up so quickly?

I made a new friend today 😄

Are you still mad over that I pointed out your pseudoscience? Burry the hatchet already, you'll only make things harder on yourself.

No you attacked my position with a statement which clearly displayed your ignorance of the topic, and so I asked you if you knew what a dimensional was.

What I suspect happened was that you looked it up, realized that you were wrong, and then backed out to spare your ego. Rather than doing the sensible thing and concede that you were wrong.

I'm not sure if you're just incapable of understanding glibness, or if you're chronically dependent on always being right to the point of being obstinate--either way, don't read too far in to other people's haphazard musings lest you be seen as desperate. You've been doing that a lot in this thread.

I don't care whether I'm right or wrong. But if you make a serious statement with without reasoning to back it up, then I'm going to mess with it.
