Slowing light Hello, This is my first post here, but it seems like there are a lot of very nice people here, so I have a question for you (forgive my ignorance, I was a failure in high school math and never took physics, but as with anything, with age you start to appreciate things more.) From what I've been reading of Einsteins work, time is relative. The only constant thing in the universe is the speed of light. Einstein stated that when light passed an object of great mass, the objects gravity effects the speed and direction of light. It bends it. If this is true, then as light is slowed down, does it regain its speed, or does it remain forever changed? My question might be confusing for no other reason than I'm having a hard time explaining my question. I hope someone can help!
