Astronomy Cast - Questions: Relativity, Relativity & More Relativity
Monday, 26 January, 2026
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? We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.
