Journey to the edge of the universe
I watched the above named documentary a couple of nights ago. Absolutely mind blowing stuff.
If you didn't, it's a journey to the edge of the universe in one shot - obviously computer generated - we get taken from planet to planet, star to star, black hole to black hole etc., until we can go no futher.
Other than what we DO know (the planets surrounding us in our galaxy etc.), was the rest of it factually accurate? Have scientists found a way to see outside the milky way? Do we know for sure what the galaxies hundreds of thousands lightyears away look like?
This is a link to the National Geographic webpage for the documentary

You can travel yourself by going to the 'Go to the edge' tab.
The documentary is still available on Sky Anytime for those of you who have Sky+ and are interested.

Daft? Daft!... it makes perfect sense if you think about Lakitu... it solves a lot of problems we'd rather not think about, no?
Actually, there's an easy answer to your question that I'm surprised that you haven't deduced. Outside, in blazing sunlight, one would have a shadow, no? I suspect that if you turned on a light bulb or lit a candle, there would be a measurable shrinkage of your sahadow... Although I haven't actually performed the experiment... I'm sure it's valid...

Who's this "we" Geezer
You won't find any Astronomers or Physicists working in Miles in this country and even in the US it's becoming a thing of the past in such circles!.
We do also tend to use Parsecs rather than light years for astronomical distances too.
The reason for this is that a Parsec is the distance where an astronomical object exhibits 1" paralax.
So it can be measured by direct observation. Other distances can be measured knowing the distace of closer ones that are measured in this way.
So the Parsec, KiloParsec and MegaParsec come from observation whereas light years have to be converted into.

OK, you can watch it at anytime you want, Naomi :o)
Press your TV guide on your remote, hit the red button, which will take you to 'Anytime TV' (it's a selection of stuff that's been on over the past week), then click the yellow button, this will take you to the Documentaries and it's listed in there..just press select.
If you start recording it while you're watching it, it will save itself into your planner for you to watch again if you want, but you MUST watch it the first time as it will only record as much as you watch.
