Physics, Astronomy & Cosmology / Re: Is space elastic?
« on: 20/10/2016 23:45:08 »
Of course if you stretch something, something must do the stretching. This could be achieved in the case of space by photons which end up at the edge of the universe. Space doesn't necessarily have to follow Hooke's Law because it is not a material.

Physics, Astronomy & Cosmology / Re: What is the force exerted by the sun on the earth
« on: 17/10/2016 11:44:29 »
So, it would seem that Newton's theories of gravity predict correct results but are not rooted in reality. The earth is not attracted to the sun via gravity, both warp the space (spacetime) around each other and travel in the lines of force that this warping generates (this seems to imply that gravity if just momentum acting along a line of force - is this a reasonable conclusion).

It could be argued that Newtons laws are digital simulations of the spacetime continuum and ditto for quantum theory. Possibly even these simulations also take place in our minds (and therefore that our minds are outside spacetime). A continuum, of course, can be approximated by splitting it up into points. The smaller the points, the closer the approximation.
