Ah, right. Sorry, I forgot about that.

Anyways, What do you guys think about that bouncing theory?
From what I know, that theory was thought up because of the one major problem of the original big bang theory. The problem of course being causality. What caused the big bang?
The bouncing theory eliminates that problem by stating that there was no cause, our universe has simply, always existed. It's just in an endless cycle of expanding and contracting, as explained in the video.
I find this really fascinating because of the concept of infinity. How could something exist forever without having started anywhere? How do you wrap your head around something like that? lol.

It's kinda like the "What came first? The chicken or the egg?" question.
Well... that's causality again, right? The egg, is the result of the chicken, and the chicken is the result of the egg. So where does it begin when the effect is also a cause of a new cause?

How do you know she's not? :P

what personal gain would she get out of this video? I'm pretty sure she doesn't expect to become a celebrity from this.

Besides, she isn't claiming to have thought of any of these theories herself. It's just an educational video man. lol

I am not defending her. I just said I thought it was interesting that you came to that conclusion.

I have a question.

She said something like the Big Bang could possibly be the result of another universe collapsing or something along the lines of that...

I'm curious as to where that universe came from. And if the answer is "it came from another universe collapsing," then where did that universe come from?

That's a great question. I don't know how we could ever know the answer.

Read a few posts earlier, I talked about this.

If you give me proof that everything needs to have a start (source), I'll answer you.

Thinking about this really hurts my head. You kind of get that feeling of not being able to comprehend something, and that feeling that people describe as being very small. Like a spec on a huge universe.

I can't understand infinity because nothing in my world is infinite. People say that numbers and such are infinite but such things are not physical.

You could walk around a sphere for infinity, but as a human I think that a person will die, and nothing can go on forever. It's just something I can't picture or imagine. It's a really weird feeling.

Anyway, off on a bit of a tangent. I find this whole thing really interesting. I have a strong feeling that I want to know what really happened, even in my lifetime I know I'll never know.

If you talk about physical, you are infinite. When you die, you'll turn into dust or whatever and in case some chemical reaction happens it would just change. Physically, you'd never end. Unless you say being infinite in the same form, which defeats the whole subject we're talking about... the universe has undergone many changes to become what it is now and probably will change.

Can you explain what your definitions of nothingness and emptiness are? You're saying that they're two different things, but I don't really get what this difference is.
Are you talking about a vacuum?

And also, you said:"Therefore it's safe to make a theory that the universe always existed, in different forms, and the big bang is the one who made it expand to what it is today."

Aren't you contradicting yourself there?
If the universe always existed, then there was no big bang to begin with. The bouncing universe theory doesn't rely on a big bang taking place, because the universe ALWAYS existed. There's no need for a big bang to start the universe if the universe has no start.

haha, I know what you mean. We really are insignificant though. Not only in size, but also time. The universe is presumed to have existed for about 14 billion years. (if you don't believe in that bounce theory) "Anatomically modern humans" have been around for about 200 000 years. Even if we live for another 3 billion years (I chose 3 billion cause at that point in time the milky way will collide with another galaxy and pretty much destroy all life lol) we will still only have existed for a small fraction of time (in relation to how long the universe will exist).

We really are a spec on a huge universe.
