A lot of people are saying and thinking that space is infinity but for me I think that the space is not infinite. It is just that we are too small to travel the whole damn space.Do you agree?
| Yes I agree! | 20 | |
| No I do not -.- | 15 | |
| I have not seen it, so I do not know o_O | 11 |
"The universe is shaped exactly like the earth
If you go straight long enough you'll end up where you were"
Thank you Modest Mouse. I don't know if it's accurate but the imagery is beautiful.
Space is infinite. Space is just the space between matte. When we examine Space, we find that there is absolutely not a single thing there. If you find any sort of matter in Space, the matter itself is not Space, it's just there. Like a rock in the ocean isn't the ocean, it's just in it. So Space, meaning empty nothingness is infinite because there is a finite amount of matter, what is not matter is Space. Because there is a limited amount of matter it cannot stretch to be infinite, but there is nothingness, or Space, outside the boundaries of matter. Hope this helps!
Yes, but it depends on what you mean by infinity. Infinity is commonly believed to be a measurement that never ends, and I also assume you are using space as "not on earth". I say it is not necessary to look that far away to see infinity. We need only look with our understanding instead of our eyes. All around us, permeating our existence, are the different dimensions. We exist in the 3rd dimension, while lines exist in the 1st, and planes in the 2nd. We see in 2d, but we use light to decipher depth, giving us an illusion of 3d vision. So the dimensions below us consist of forward and backward(1d lines), and then at 2d (planes) there is forward, backward, side to side, and diagonal. But there is no depth, no up or down; thus a 2d entity could not perceive a 3d entity because there is no such thing as depth to them. A 3d entity would seem to them infinite because it would seem to never end, flashing into existence and then vanishing instantly. So, as 3d beings, we can only truly perceive 2d objects; we never see true 3d. Thus a 4d being would be able to see in full 3d, seeing through us, around us, inside of us all at the same time. Any being above 3d would seem infinite to us because we cannot perceive it. -so yes, space is infinite in the sense that we can never perceive the entirety of our reality.
Spacetime itself is expanding. One common misconception is to think of it as a huge void that was waiting to be filled by the big bang.
Is the universe moments after the Big Bang considered infinite, even if it was "smaller" (if that's the correct way of putting it)?
That's difficult to determine. If it is wrapped-around then it is finite and was thus smaller. However, what's the meaning of distance when nothing exists outside? There's no universal measuring stick to use for reference. At the very least it was denser and hotter, so much so that atoms couldn't form. In fact anti-matter was initially there and particles-anti-particles kept annihilating each other and being recreated from the very gamma rays their annihilation emited.
I know, I studied astrophysics. I was just trying to explain what it means for something infinite to expand in general, and I guess I didn't do that very well. My point was to say that something can expand without having boundaries.
Have you looked into String Theory?
I have wonder if it was infinite. If only there was some kind of scanner or some other device that could prove this. I've always had a hard time believing that it was infinite and that eventually it's growth would stop.
So then where does it end? And the wall that it ends at, is that infinite? Is the space outside of space infinate?
Something has to be infinite.
The universe is huge. Even if we humans wanted to explore it, we couldn't. It's just too vast.
