This new book about Einstein has got me thinking once again about the universe.
Einstein's theory of relativity predicted that gravity would affect light and make it bend. The theory was confirmed with observation during a solar eclipse.
That brings up two questions to my mind:
1. Does light have mass since gravity affects it?
2. If light will bend, then theoretically it ought to be possible to:
a. Make it orbit
b. Catapult it around a massive body and increase it's speed as is done with satellite launches. This would mean light ought to be able to travel at speeds faster than the speed of light.
