'The Sky at Night.' They went big time this month toying with some of the strangest ideas in physics.
The Multiverse ... suggests there are alternate Universes, possibly an infinite number, with every conceivable combination imaginable. So out there, are an infinite number of forums like this one, with an infinite number of
@staffordjas which means an infinite number of large incoming asteroids. While I am an observer of Clarke's First Law, I do have trouble with this one.
Dark Matter. No doubt it's out there, we can see it in action. What it is, is as yet unknown.
Dark Energy: Two words describing why the expansion of the Universe is accelerating, and that's it. Two words chosen I think because it sounds cool. It only gets a mention, because that's all we know.
White Holes. The opposite to Black Holes, but reversed. (Everything comes out, nothing gets in.) Might be where our Universe came from. Why not ? I say.
Communication with aliens: A subject of interest to anybody interested in radio, although I've personally communicated with aliens numerous times on my way home from the pub.
Interstellar travel. Unless our physics is very wrong, this is tricky. Yes you might be able to fold space, but ... it requires energy far beyond anything we can understand. (However, see Clarke's First Law.)
There isn't another Sky at Night until 2023 now, but I figure this is more than enough to chew on.
