Re: Researching an Idea

On a related issue. I remember there was some physist who did an
experiment where he fired a laser in different directions into space
and measured the power used. The theory was that if there was no
electrons along the path that he fired the laser, it couldn't operate
and would use up less power. His results were that the power used was
independant of direction to the accuracy of the experiment.

My understanding is that if the matter in the universe was in a finite
region and the universe itself was infinite, then in theory it would
not be possibile to fire a laser past the edge of the finite region as
there would be no electrons in the "empty space" after the edge of the
region which happened to have matter in it. Matter in the matter
filled region would diffuse into the empty space surrounding it , but
it couldn't move faster than the photon of light.

For example, assuming that the universe was just one star and a few
planets and some gas that is gravitational bound to the star, would the
star be able to emit light to balance heat generated by fusion? Also,
maybe the quantum vacumn would be sufficient ... they photons would be
absorbed by virtual electrons and then re-emitted to be re-absorbed by
more virtual electrons.
