We started with EMW, not needing a transmission medium. Both charge and gravity exert themselves in the vacuum of space. Can waves carrying momentum along a time axis, from the previous posts, transmit across vacuum space, \(x_3\)?
Yes.
We receive heat from the Sun in the same way. Heat, not positive hydrogen, protons that combine with \(O_2\) in the atmosphere to give you sunlight and heat.
Have a nice day.
