"The word 'ether' has extremely negative connotations in theoretical physics because of its past association with opposition to relativity. This is unfortunate because, stripped of these connotations, it rather nicely captures the way most physicists actually think about the vacuum. . . . Relativity actually says nothing about the existence or nonexistence of matter pervading the universe, only that any such matter must have relativistic symmetry. [..] It turns out that such matter exists. About the time relativity was becoming accepted, studies of radioactivity began showing that the empty vacuum of space had spectroscopic structure similar to that of ordinary quantum solids and fluids. Subsequent studies with large particle accelerators have now led us to understand that space is more like a piece of window glass than ideal Newtonian emptiness. It is filled with 'stuff' that is normally transparent but can be made visible by hitting it sufficiently hard to knock out a part. The modern concept of the vacuum of space, confirmed every day by experiment, is a relativistic ether. But we do not call it this because it is taboo." - Robert B.

Laughlin, Nobel Laureate in Physics, endowed chair in physics, Stanford UniversityMatter, quantum solids and fluids, a piece of window glass and 'stuff' have mass and so does the aether.Robert B. Laughlin must be suggesting a type of grid structure pervasive throughout the universe as a relativistic Ether. And if what you are suggesting the Ether has mass for c then energy for c must also be part of c being a constant. A spin of c on Ether particles would satisfy light being a constant wave as is all of the EM spectrum. In that case the Ether would actually be the cause of electron motion and dilate the length between atoms. Those atoms would carry that dilation with them and rotate with a body of dilation moving the electrons within that grid pattern. Yes in a case like this there would be a null result from the MMX. But we have done so much progress without the Aether particles do we really need to go down another path?
The cause of gravity has a simple explanation. Entropy of mass. Mass causes the dilation of space (curved space). This is observed in galaxies as lensing. So dilation of space by mass is an observed phenomenon. In the center of mass is the most dilated space as observed by clock tick rates being the slowest tick rate position on a planet. Red shifted light in GR is considered to be less energy. Red shift is the greatest in the gravitational center of a planet. So we can conclude more dilated space suggests a less energy position in space as an observation. If we consider dilation of space also dilates mass that occupies that space we can understand why light and mechanical clocks both slow equally with greater distances of light and the electron to travel to create physics the same in every frame.In that light we can consider energy being dilated (red shifted light being produced in more dilated space). Now for the potential energy as an attractive force of entropy. We can now follow gravity as simply mass being attracted to a more dilated position in space of less energy. in Relativity light bends away from and curves around dilated space while mass is attracted to a more dilated space position. Einstein appears to be correct in dilation (curvature) of space is the cause of gravity.To give up on the cause of physics is very unscientific. It may always remain a subjective interpretation of cause but explanations need to be consistent with observations.
what i mean is that is it caused by the earth's spinning motion?? or what? if not than what causes the earth to spin?? why is it spinning??Hello Hamza,The jury seems to be definately out on this subject. I suggested it spins to remain stable in space but not all agree with this as the gravitational pulls from the far away stars and galaxies are very small.I will look at the pull between the milky way and Andromeda nextRegardsMike
The alternative theory is that gravitational attraction is mediated by an as yet hypothetical particle the Graviton but the mass of such a particle would be so small that there is no hope of detecting individual particles
What causes gravity?
