I had a good question from Paul Gilligan about my theory on Dark Energy being cosmic gravity. “Here's the thing. Even in a vastly bigger, perhaps even infinite Universe, there would be pretty much the same amount of mass pulling the distant galaxies towards us as away from us. The net effects would cancel each other out! Something else is afoot!”
I replied saying that this is something I thought a lot about before going public.
Here is a fuller explanation.
What do you think this is a picture of?
Well this image of the sky could have been taken 50 years ago 100 years ago even a hundred and fifty years ago. In fact it's a picture taken by the Hubble telescope in the last couple of years.
The point is that the universe has always been much bigger than we thought. If we could take an image of the cosmos it would probably show a similar pattern of objects only they would be dark matter or black holes so bright shiny lights.
BUT THE PATTERN OF DISPERSION WOULD BE SIMILAR ie RANDOM.
At the moment of the Big Bang the source of our universe would have existed in a gravitational equilibrium with the rest of the cosmos. Not static, but dynamic, just like the stars and galaxies in our universe.
The initial expansion of the universe was fueled by the enormous energy released at that time. Just as the standard theory explains.
Thanks to phys.org for the image.
The universe expanded quickly but some theories suggest that it may have been slowing down under the force of its own gravity. Without Dark Energy it may have reversed - the big crunch.
But about 5 billion years ago it started to accelerate out towards the cosmos.
Today it's said that the universe is 93 billion light years across. 5 billion years ago it was about 50 or 60 billion.
It was at this point that the outer galaxies had moved far from the centre of gravity of the universe and into the gravitational pull of the cosmos.
The answer to Mr Gilligan's question is that with the universe stretched out to 50 billion light years the gravitational pull of the cosmos would be skewed and not equal in all directions as he suggests.
Dark Energy is the gravitational pull of the cosmos.
As I say in my website, if we could accurately measure the accelerations of the outer galaxies - but we can't yet - we could show that it fits this model.
Although the maths of the model is beyond me, it's pretty simple stuff. Just need someone to do it.
