We took a bit of a detour last week, into ideas about warping of space and time, that we’d originally intended to put off until this week. No problem with that — science at its very essence is about taking unexpected detours. So this week, we going to try to go back to last week (or rather the last week that never was) to talk about what the implications of the constancy of the speed of light are for mass and energy, and how this leads to atomic bomb, and the ability to create weird and wonderful new types of particles in particle accelerators like the Large Hadron Collider. And if there’s any time left over, we may get to Einstein’s theory of general relativity, what this means for gravity, and how mass causes space to bend.

And remember, BigScienceFM is not a monologue but a conversation. We want you to butt-in, whenever the spirit moves you, with questions and comments, via the @BigScienceFM twitter feed and hashtag #BigScienceFM.
