This week we wonder if you can made a black hole by accelerating a mass, but then can you un-make it again? Will the Earth ever be tidally locked to the Sun? And can dark matter crush an unsuspecting space ship? If you've got a question for the Astronomy Cast team, please email it in to [email protected] and we'll try to tackle it for a future show. Please include your location and a way to pronounce your name.
