I'm listening to old coast to coast episodes.

The salient points:

1. Most of the universe is dark energy, which is killing it. (the universe, that is)

2. Parallel universes are trendy but Michio Kaku is avant garde.

3. We might have to move to a "baby universe", if we're even around because...

4. The Royal Astronomer of England thinks we have a 50/50 chance of making it to the year 2100, and he's quite optimistic.

On the bright side:

5. we may eventually use sea water as a fuel supply!
