Questions Show: Undoing Inflation, Searching for Water, and Seeing Everything a Black Hole's Ever Eaten

Expansion of the Universe

If there was enough mass to cause a big crunch, would inflation go backwards too? How do spacecraft know that hydrogen is bonded to water? And why can't we see everything that's ever fallen into a black hole?

Questions Show: Decelerating Black Holes, Earth-Sun Tidal Lock, and the Crushing Gravity of Dark Matter

Artist's impression of a black hole

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?
