Heya guys
I have a few general questions.
The first one is about Stephen Hawking. How does he express his ideas these days? I saw a thing about him on TV today and it seemed as though he has extremely limited motor function in his hand, and he can't speak, except for the text-to-speach thing he has. But how does he write the text? It must be a god-awful slow process for him.
The next is about Einstein. The program said according to Einstein if you ran next to a beam of light the beam of light would move away from you. I have a basic understanding of relativity (moving at a fraction of c gives time dialtion, etc), so how does that explain the light moving away from you? Is it because for you time would slow down but the light doesn't?
My next question also involves Einstein. It's about gravity not really being a force or whatever. According to the program the Earth revolved about the sun because the sun warps the space time around it. So if I drop my cell phone and it hits the earth, is this because the Earth warps the space time around it? I don't understand this part.
Thank you kindly
