When I got across the term space-time, I thought it is just another term for the micro-vibrations in the ether. The vibration pattern are quantizing the ether to space units and to time periods. I know that absolute space-time cannot be measured because observation is based on matter. But isn't matter just modulations on the quantized ether? (Ether deniers call the quantized ether 'vacuum'). The modulations do change their space units and time periods with velocity. We cannot measure any changes when our references change as much as our values. It's the principle of relativity. But there are changes, if we have references of some matter and take the space units and time periods from matter with a different velocity. I thought, it confirms that space-time is generated by the modulated micro-vibrations called matter. The ether was introduced to explain waves. The ether has no references which just means that no values can be assigned to the ether. Energy conservation requires that the ether must be filled with wave energy that cannot get less or more. Oncoming waves become vibrations and vibrations are arranging themselves into a lattice of wave pattern. Wouldn't gravity go into the direction where the wave pattern lattice gets more blurred? Non-mechanical people call the vibration forces 'electromagnetic forces'. It is known that the electromagnetic force carrier 'the photon' can change the different vibration modes of temperature and the vibration pattern of orbitals. Note: This question is also posted on the Physics Forum but the background information to my question was perceived as a fringe theory. I cannot see that my background information disagrees with the standard model. However, my physics education comes mostly from the Internet.
