How can we see the center of *** universe?

colinuk · 12 Jul 2007 at 17:20

Would the distane fromt he object matter? as in if the object is say 50 ft away, then the light would be hitting you quiet a lot, but if you move it away, say 500ft, are only say 10% of the light rays now going to hit you and be seen?

Like if you take an apple, cover it with lasers, the further away you are, the less lasers will target you, or do light particals act in a way not like a laser?

Dam, this is deep......

I will stop now.

colin, sorry to anyone getting a headache

The current theory if I understand it correctly is that the shape of the universe is like that of the plastic part of the football. The big band set the universe expanding but there is nothing inside it, there is no inside actually.

That helps to explain the curvature of space. If you set off in any direction in a perfectly straight line then you'll eventually end up back at the point in space you started. Theoretically..

Well the ball metaphor works for the x and y axis.. the z axis (depth of the plastic of the ball) it does not quite explain. Somehow that curves around too to end up at the same point. Probably something to do with a 4th dimension.

The bang has to come from somewhere and start from somewhere.

Or - are you saying its like a linked mine field? one goes up and the whole field goes with it, now that throws new light on it.... o.O i can feel my toes twitching lol..

that would explain why there is no centre too... to many bangs.

one other question.

why did the forum filter take the word 'the' and *** it out? lol...

You are assuming that there was space before the big bang in which it occured. This is not the case. There is no before-the-big-bang (that we will ever be able to know about, i think). The singularity of the big bang was ALL of space - it did not occur at a position within a pre-existing space.

colinuk · 12 Jul 2007 at 17:26

So, in the 1st place my view of a bang being a BANG is not quite right, so if i start off wrong, no wonder it doesnt add up...

fair enough, will go work it out with the help of a few strongbow ciders tonight in leeds..

Good to be able to talk somethign out with you guys, cheers.

Colin - aye - i know, i lied, i posted again lol..

Slam62 · 12 Jul 2007 at 17:27

yeah right!

space didnt exist before space uh because the big bang created it.

no, no and no

everything has been here forever dude, space was always here so was stuff

matter is neither created or destroyed everything is somewhere man

No, because the earth is travelling slower then the speed of the, the light that comes out of it 100,000 years ago was already coming in this direction at a speed greater then us so unless we learn to go faster then the speed of light we'll never catch up with it.

hmm. we can see stars going super nova millions of years after the event took place. if earth was in the position of one of those stars, wouldnt we see it?

hehe, mind bending

Think of a light bulb. If you're close to it, it's bright. As you move further away it gets dimmer.
Your only error is that as you move 10 times further away you're actually only seeing 1% of the light you were seeing.

This is because they are so far away from us. If an event happened at a distance 20 light years to us, we won't observe the event til 20 years later.
With earth being rather close to us we observe events immediately. If earth was in the position of one of those stars, and we were on a star in earth's position then sure, we'd see it, if it's bright enough.

i think the real question is ... if the universe is infinite then that means there is infinite possibility .... does this mean that on a distant planet there is someone exactly the same as me currently masturbating on top of the empire state building aiming for the lizard people?

bingo bongo! so, if the earth 100,000 light years closer to the center of the universe, 100,000 years ago, then we perhaps could see earth if we looks in the right direction....maybe.

heres another one

If the big bang started our universe off, that would mean there was a huge mass existing before the explosion, how was this great mass created? and are there any more mass's big enough to create another universe in the infinite world of space.
Think ive just confused myself :confused:

We can see those stars because they're that distance away when the event occurred.

We can't see the earth 100,000 years ago because we are on the earth.. You can't see further back in time then the distance from the observer to what you are observing. Essentially if I looked at you I'd be looking back in time a tiny tiny fraction of a second. When we look at the moon we're looking back in time about a second. When we look at the sun we're looking back in time 8 minutes. etc...

Yes, but if there are infinite possibilities then I really don't want to think about some of them. Let's just say they involve you and sweaty old men who like to be called daddy.

The big bang wasn't an explsion in stuff. It was an explosion of stuff. There is no "before the big bang" and the question is basically irrelvent.

UnusualSuspect · 12 Jul 2007 at 18:04

The only problem I have with the big bang is where the bang came from. Why are we living in a bubble formed billions of years ago? Whats outside the bubble? If theres something outside the bubble then what went bang to create this universe, and did it have a devestating effect on whatever was living there before it happened? And if something was living there, then where were they? How can something simply not exist and then exist? It makes no sense at all.

Maybe it was God? But where is God and how does he exist? Where does he live? If he lives somewhere then what was there before he was?

The universe, to me, simply makes no sense whatsoever, whichever way I look at it.

Maybe but energy can neither be created or destroyed, so what caused the chain of events that caused all this energy to convert to the expansion of the universe.
Any info on the "nothing before the big bang"?

We don't know what was before the big bang and we can never know. Yes, energy can never be created, and I believe thats one of the flaws of the big bang model.

What I'm saying is that we dunno if there was anything before the big bang, which is why there is no "before the big bang". It's why the question is irrelevent because the question can never be answered.

Bare in mind that the big bang might not even be how it began, just right now its the only theory that explains a lot of whats went on.

The laws of physics as we know it only exist in our universe, and hence only valid post big bang (and even then some people think the laws of physics have not always been static after the big bang, talking millionths of seconds after).
