Astronomy Cast - Questions: Relativity, Relativity & More Relativity
From October 23, 2008.
Hosted by Fraser Cain & Dr. Pamela Gay.
Everyone loves a theme. And this week we've collected together some of your questions about relativity. More light speed spacecraft, twin paradoxes, and the mixing up of gravity, time and mass. If you've got a question for the Astronomy Cast team, please email it in to info@astronomycast.com and we'll try to tackle it for a future show. Please include your location and a way to pronounce your name.
- What would happen if you're traveling close to light speed through the solar system — would you mess it up?
- If I watched my friend accelerate close to speed of light, will I see him get younger or age slower?
- Can parts of the Universe be traveling back in time?
- What form does relativistic mass increase take?
- Why don't photons have mass?
- Twin paradox: Why is the "stay at home" twin's frame of reference preferred?
- Does gravity equal time?
- How can the state of an electromagnetic wave change when the wave exists outside of time?
- How do we know the speed of light constant? Could it be different in different part of the universe?
