No light in vacuum space

Stupid scientists think light traveling in space at light speed, they don't know the light is alternating current in the medium, light must coexist with the matter, there is no light in vacuum space.

Light speed is the electrostatic force propagating speed in the medium. Light induces light simultaneously throughout space, light speed in space is infinite.

All the lights in the universe shine simultaneously at forever ongoing now, light has no past and future, all existence is at forever ongoing now.

How to prove it?

If light exists in the vacuum space, the night sky will not be dark. If light exists in a vacuum space, the color laser beams will not disappear in a vacuum glass bottle.
