Title: If gravitons gravitate do they expand the universe?
Post by: jeffreyH on 13/11/2016 23:59:04
Since the big bang there has been a lot of gravitational radiation. Could this dispersed gravitational energy be the cause of the accelerating expansion of the universe? The mechanism would be via a gravitational field generated by gravitons. Thoughts?

Edit: In the expanding balloon analogy it is the dispersed gravitational energy that is now expanding the balloon.

You're thinking of energy?
Like binary stars 'acting' on each other through 'gravity'?

then again, this 'Big Bang' is a local phenomena, isn't it?
Meaning that its 'origin' was 'anywhere'.

I wouldn't bother with it yor_on. It was me as usual putting fingers to the keyboard without thinking it through. It just wouldn't work.

  As I see it, the physical universe that we see and measure is a balance point between dark matter and dark energy.  The more we lose matter into energy, the universe will expand. And thus the universe operates just like a balloon.

Nah man, I like the way you search, Don't give it up
