Had to go out just when I noticed the additiond here.. talk about hurry back this stuff is what I live for.
I agree that gravity is the key and I have been doing my best to solve the problem. My view is gravity does not act in an attractive manner at all..our human experience interprets it so, however I strongly believe that is pushes...contrary to popular views and idioms ...gravity does not suck
.
Maybe it is impertinent to offer a solution but the reality there is so little out there that gives any approach.. I can not go along with string theory and its attempt to explain gravity as a weak force that is actually a strong force that "leaks" some of its energy into "änother dimention" so as to leave it , in our dimention manifesting as a weak force. I can not review string theory because my math sckill in below the level required to work in that area.
However if gravity acts as an attractive force that requires a sort of "radar"approach..there being required a message to one body to another and back again ..to determine its presence etc and a return of the message. This indicates that gravity must travell at twice the speed of light to get there and back and still show gravitation acts at C. Whereas I see gravity as a universal pressure produced from the outpouring of energy/particles from all bodies in the Universe such that we are not held to this planet by attraction but by this energy or particle pushing us against its surface.
My answers were posted elsewhere including the possibility of such a Universal pressure to answer many of the current dead ends faced by our current understanding.
