Exactly. All we can go for with bigger and better telescopes is better resolution and higher sensitivity to light.mikenet2006 said:So this means the more powerful telescopes on the drawing board today will actually not see much further out than hubble at all, but will see the things within the current visible universe better and with less glare so we can directly view planets outside our solar system?
I remember reading about it in SA a couple months ago. Can't recall the name of the telescope though, so I can't google it.mikenet2006 said:"" I saw a little about a dual lens telescope that looks like a pair of binoculars that will see planets orbiting other stars without the blinding glare you get with a single lens telescope while aiming it near a distant star """
This should be in construction by now because the special I saw on this is now five years old. I havent heard much on it lately though.
If the big bang was simply a giant explosion, that could certainly work. However, this is a misconception. Big bang didn't happen in a pre-existing empty space - rather, space itself "unfolded" out of the big bang. I think the balloon analogy has already been mentioned sometime earlier in this thread, look it up. Anyway, since there was no universe for other hypothetical big bangs to happen in, the point is moot.mikenet2006 said:That would strictly depend on whats beyond what we are currently seeing today though. To be visible it couldnt be connected to our set of galixies. It would have to be part of an independent group of galixies that were created by a big bang of there own, but this big bang would have had to occured ages before ours to alow the light to travel in this direction long enough to be visible from here.
As I said above, I don't think that our current conception of the big bang allows for more than one of them. However, what you say might hold for an oscillating universe that cycles between expansion and contraction, every contraction being followed by another big bang (ie. big bang -> the universe expands -> expansion stops -> the universe contracts -> big crunch (or gnab gib) -> another big bang -> etc.). Now since the early universe was not permeable to light, using telescopes wouldn't get us very far in this regard (as we wouldn't be able to see past the first 300,000 years or so). It is not inconceivable, however, that some sort of different traces of a previous universe might have survived the big crunch/big bang and are waiting for us to discover or recognize them.mikenet2006 said:in a sense maybe space has a record of all ancient universes that formed long before ours, just waiting to be viewed. In the form of the light they produced when they exsisted still remaining and traviling outward from there point of origin.
