Please excuse my ignorance .. I know very little about this subject so this is why i am asking the following questions.
I have just watched a programme about Jocelyn Bell Burnell who discovered Pulsars in the 60's .. very interesting indeed.
One of her last comments were about scientists of the present/future and questions they will be finding the answers to .. Such as why is space accelerating faster than at any time in the past?
Like i said .. Knowing very little on the subject, i have just grabbed a pen, done some freaky little diagrams, and made notes .. So if you know the answers to any of these questions then i would be grateful for your insight in this matter ..
Could the universe a particular shape that could explain the acceleration?
Is it a shape at all?
As energy is being used, you'd expect to an extent, de-acceleration over a period of time .. That would be the simplest of answers .. This is wrong or inaccuate to them .. But if something is churning up all this energy (both my index fingers are going in a circular motion there) couldn't the motion build up to actually increase acceleration?
Or could possibly as the big bang happened at a particular point and has been extending outwards since .. Could not maybe the space it's now entertaining be filled with something different (maybe denser) than what it has in the past?
And lastly .. the big bang happened 14 - 15 billion years ago .. If we have gained the knowledge to witness the beginning of time (big bang) then why can't we go past that to see just where the universe actually ends???
That is very black and white, i know.
A stupid question is only one that is never asked ..
