Hubbles Replacement

DRCORTEX (Lance) · #1 14-01-2006, 04:58 PM

I saw the 15 years of Hubble documentary ( great production if you havn't seen it - well worth the search ) - and they mentioned the Hubble replacement, due 10-15 years from now.

The resolution from the new scope is expected to be 15X that of Hubble. Now, considering that Hubble has bought us to its' limit, and the deep, deep space exposure that was taken over 20+ days, bought us to the limit of the scope, and so the documentary says, close to the limit of space/time, my question is

What happens at the end of space/time - is it a brick wall, with the word "God was here" or such ? How do you measure the boundary ? and what defines the boundary ?

There is a really extensive conversation about that exact topic in here somewhere Lance. If I can find it I will place a link in here to it.

There are some very interesting points put across from all sides!

G,day Lance

I believe our universe is finite and has no boundry. Hubbles replacement will see the first generation of stars shortly arter the big bang and who knows what eles?

I too believe it goes on forever, but that wasn't everyones view. I'm still looking for the thread about it.

Hope to see the link - a really interesting topic

It wasn't just matter that was created in the big bang space was also born. For the last 13.7 Billion years space has been expanding with the matter in the universe, there is only a finite volume of space in the universe so space is not infinite and it has no boundry because remember the big bang didn't occur in some pre existing void, space was created with the big bang. There is no edge to the universe, you cant 'go' beyond space into something else so therefore has no boundry.

I hope I havent too badly confused anyone

It is clear in my mind but my grasp of the english language is not great.

Cool subject, hey

Micko, I think you just supported both sides of the argument in one statement

ballaratdragons (Ken) · #8 14-01-2006, 10:38 PM

Lance, I found it. It was started 10 months ago. Feel free to add to it.

OH NO!!!!!
This is where vings straw propulsion started

Sorry wrong thread

Best of both worlds! Or is that 'best of both Universes'

Slick, don't tempt me to ressurrect the 'Ving Straw Propulsion Theory' thread!

Lance

The end of space/time is a singularity, inside a black hole. But as I said previously space has no boundry there is no wall or thing at the edge of the universe.

Yeah

The best explaination I have heard is that the big bang created the fabric of "'Space/Time" everywhere at once!
The effect of the passage of "Time" as we experience it (keeping in mind that the passage of time is relitive to the speed which you are travelling). Is that the fabric of Space/time is expanding, that is to say that all the clumps of matter in space time are streching further apart.
The evidence at hand as of now is that it will stretch to the point where matter as we know it will cease to exist!

A long long time from now (I think it was something like 10 to the 32 billion years) Then there are parrellel universes etc.

Luckily we just have to live on our little bit of rock, and do our best to expand our minds, enough to realise we are all in this together (so we had better learn how to get along)

Sounds good to me

If it was finite wouldn't it have boundaries?

Space was created with matter and time in the big bang. because this happened a finite time ago (13.7 billion years) space is finite. But before the big bang there was no pre existing space so there is no edge of the universe as such. You cannot keep going until you find some boundry because space time is curved.

That my thoughts on the subject anyway
