Gravity and Light
Does light have mass? If light is made up of photons, then it must have mass. According to scientific experiments beginning in 1919 with Arthur Eddington, light’s mass is acted on by gravity.
This fact raises a conundrum. From where does light get the energy to accelerate to a speed of approximately 186,000 miles per second? How much energy does it take to accelerate one photon from 0 to 186,000 miles per second and maintain that speed across millions of light years. (A light year is the distance light travels in one year traveling at 186,000 miles per second.)
Still puzzling, if the photon is coming from a star(sun), would not the mass of the star cause gravity to “suck” the minuscule photon into the massive star? Something does not seem logical here.
Of course, scientists might point to nuclear energy. Yes, we have atom bombs and hydrogen bombs which they liken to a miniature star. The problem there is that the star disappears after the initial explosion. The “hydrogen star” blows itself apart and disappears. If the excuse is that it is so massive that the “hydrogen star” gravity holds its mass together, then photons, which are extremely light, would surely be sucked back into the star and no light would be emitted.
Just a question.
How does light photons travel with so much gravity in the universe?
