The Size of the Universe

That would be cool. i think we will die before the humankind’s meeting with the aliens

did anyone post this yet?

Scale of the universe

Isn’t that the theme from Spore? :stuck_out_tongue:

Yes, but that one runs smother than mine for some reason.

I think that the universe is actually much bigger than what we are able to see, because, what we do see far away is the universe when it was younger, but I guess that if we can see that far immediately, not at light speed, maybe we would be able to see incredible thing, but, what if the universe is an infinite space? :fffuuu: This is crazy I know, but think, what if the universe always existed, and that beginning never existed? It crazy when you think about it!

(Sorry for my english, I know it’s awful :retard: )

It’s not crazy and it seemed reasonable at a point in history untill Edwin Hubble proved with the shifting of galaxies that the universe is expanding. This rules out the theory that the universe ‘always existed’ because a universe wouldn’t just “be there” and then suddenly out of nothing start to grow at speeds beyond your imagination (dark energy is causing this).

Also, the existence of matter in our universe (planets, stars etc.) is not eternal. At one point in time the universe will almost be completely empty and the spacetime dimensions will have grown so large you might aswell call it infinite - this is so far ahead in the future though it’s just not possible to comprehend (talking about quadrillions of years here).

late response , and sorry if it’s been brought up before

well erm … i think it is unlimited … you just reject it because you cant grasp the idea … but … if by some possibility the universe does have an end - what’s beyond it ?

Nothing. :retard:

nah … there’s probably spaced out garden gnomes and astronauts with crowbars … im not thinking randomly enough :frowning:

“Nothing” implies infinity to me.

or just more empty space ? … a lot of people consider the end of the universe to be the point where there isn’t anything except vacuum and nothing else …oh wait…

Well, according to the string theory, shouldn’t the universe end where the strings does?

pretty damn long string i guess ? ooh and what color :retard:

I’m not even gonna bother fucking posting here, people don’t even read it even though I’ve posted three times the universe is not infinite and that the question “what lies beyond” is not allowed due to the fact that there is no space nor time.

I read what you said. I don’t see any proof, and I believe you are wrong.

Um. You can’t get BEYOND it because there’s no such thing as “beyond the universe”. It is a gibberish concept in the same vein as “before the Big Bang”.

Time for some mind blowing stuff:

The universe is all that exists. If there was a “beyond”, then that would be part of the universe, too. The universe is finite in size, but has no boundaries. You can’t really get to the edge, technically speaking, because there isn’t any edge. “Edge” is a byproduct of Euclidean geometry and only works in math books.

In Euclidean geometry, the sum of a closed triangle’s angles equal 180 degrees. A right triangle is defined as a triangle with one right angle and two acute angles. It works perfectly…on paper. However, once you get into reality, things get a touch different.

It is quite easily possible for a right triangle in reality to have TWO right angles with the sum of their angles equal to greater than 180 degrees. How? Place a point on the North Pole of the Earth and call it point A. Place a point on two points on the equator of the Earth and call it points B and C. Draw line segments between these three points. The measurement of angle ABC is 90 degrees. The measurement of angle ACB is 90 degrees. A closed triangle with two 90 degree angles.

The surface of the Earth is curved, allowing for this to occur. It is non-Euclidean. You can travel in a straight line to the west forever around the globe and never get to the end because there is no end. You’ll just keep going around the globe into infinity.

Spacetime, also, is curved like this. You can travel forever in a straight line and never get to the end of the universe. You’ll just end up going around the universe over and over again like going around the Earth over and over again. And the space between objects in this finite but boundaryless universe is growing (currently).

This is Stephen Hawking’s and Carl Sagan’s position on this matter as well.

Yes, Mindfuck Central, I know. Causes you to possibly pull this face: :fffuuu:

But that’s the current working theory in our VASTLY ignorant understanding of the universe as it now stands. Could we be wrong? I most certainly don’t doubt that we are wrong, but that’s what the information we have available to us is currently taking us. Into Mindfuck Central.

:freeman:

i watched a Documentary last night. İ heard they perfected a spaceship.That could reach Alpha Centauri (nearest Star System). But the problem is They need negative energy (As i remember) as big as Saturn. And we can only create negative energy size of a microbe (again as i remember). İf They could solve this problem we could go faster than light speed. But the man said. They probably won’t be able to do it in this half-century.

okay , you have a point , i drop the “beyond” b.s.

well i just didnt bother reading all the posts :meh:

Thanks, Danielsango. I said basically that a few pages ago, but much shorter, and I was pretty much ignored :retard:
