Really enjoyed this episode. Thanks to Fraser and Paul. The regular explanation of virtual particles and Hawking radiation I've heard and read so much that I can recite it. But this gives some new depth to get my head round. Muchas gracias Diario Universal!
Okay, here is a related aspect of this topic that I can't find an answer to: You know how they say that a large black hole will evaporate slowly over eons, and a microscopic black hole will evaporate very quickly in a burst of energy? 1. Can we get a layman's explanation of this? 2. Why does it evaporate faster when it is tiny and not faster when it is large? (ie: what is the underlying explanation of this proportionality?) 3. Considering that we haven't observed this behavior directly, how can we be so bold as to desire the creation of a microscopic black hole at the LHC?
Did you see the episode on why black holes evaporate? The gist is that the temperature of black holes is inversely proportional to their size. So, the higher the temperature, the faster it evaporates. I'll do an episode on why it's safe to make microscopic black holes.
Awesome! That was the best episode yet, and a great blooper!
