Paul I can see any forum members who see you asked me such a question will be pulling their hair and shouting at their PC's...."on no dont get him started on that......""
It is an old concept ... I used to think I was the first person to have the idea but it goes back as far as 1745 first recorded by a fellow by the name Le Sage..
It boils down to the philosophy that thru out the Universe there is a flow of small particles that in effect push ..bodies do not attract but shield each other from this flow of particles and pushed each to the other.
If you Google The Gravity Push Universe you may find a site someone started for me but I have not acted upon other than my general ideas of this philosophy
..ther e is another place I rave on about it
... but the concept works for me
.
Perhaps a quick way of seeing it ...is a Universe with "dark energy" (a recognised pushing force at times related to Dr A's cosmological constant) but
with no attraction in the mix (I don't believe there is a mechanism by which attraction can work and what we interpret as attraction is invariably a push)..
It is figuring out where from that will confuse you..but think that this push is so grand it holds galaxies in place via an external push of all the particles flowing from every where...galaxies can not hold together via an internal force such as attraction but only via an external force to hold them in place ..attraction can not do it..that is if C is the max speed in the Universe...
I am not saying this flow is light but if you think of how light permeates the Universe well replace every light beam with a particle flow that in effect pushes..you we see this push will be everywhere...move your finger tip to a point in the Universe where the light from all does not reach it..takes some time to appreciate the magnitude of that mouth full...
Thank you so much for asking but I suspect you made a few people just about have a heart attack
... it is a subject I tend to be obsessed with unfortunately.It is my hypothesis as to how the Universe may work and although not claiming it as a theory ..as it is an idea..it is my TOE...cause I can link the flow to all energy and unit the forces... but no need to get excited Steven Hawking gets 5 or 6 TOE's each day so he says..its just another idea.
Thanks for asking
and may I take this opportunity to apologize to Bojan for running off a little
