But apart from that, what have the Romans ever done for us?I would say key concepts are phase transitions, quantum tunnelling, space-time geometry, false vacuum, bubble nucleation, spontaneous symmetry breaking etc.

Space is big. Really big. So big it's hard to imagine just how big space really is.

So, feel free to get a book on the universe, but just remember that you don't really exist.None. Although you might see people from time to time, they are most likely products of your imagination. Simple mathematics tells us that the population of the Universe must be zero. Why? Well given that the volume of the universe is infinite there must be an infinite number of worlds. But not all of them are populated; therefore only a finite number are. Any finite number divided by infinity is as close to zero as makes no odds, therefore we can round the average population of the Universe to zero, and so the total population must be zero.
Thanks for the recommendations, particularly to Hitch for putting so much effort in.
I'm going to go with Prof Pointy's recommendation at first,with Marin's duly logged (it is bloody expensive!) and with Hitch's also logged.
There are two moons? Jesus! I really do need to catch up with my reading!!!If you fancy an online course there are a couple of astronomy related ones on FutureLearn. I've done both Moons and In The Night Sky: Orion - both very enjoyable.
