Hi, it’s Stephen Wolfing, science correspondent at the Greenygrey. Watching Channel Four, I was thrilled to see that my human version in the parallel universe planet Earth thingy, Stephen Hawking, opened the London Paralympics 2012 last night, with an inspiring message about reaching for the stars.
The opening ceremony went on to provide lots of fun, moving and spectacular displays, including some greenygrey ones:
Horizon: Mapping the Universe
The opening ceremony’s emphasis on science and space was nicely timed after the BBC‘s Horizon this week covered the attempts being made to make a 3-D map of the universe, and the current theories on the size and contents of the universe or universes.
Amongst many things, it thoroughly explained how our understanding of the observable universe is limited to what light has had time to reach us, and that galaxies are not moving away from each other; the gaps between galaxies are widening because the universe is still expanding.
It ended by showing how the universe is thought to be infinite, and could be one of an infinite number of such universes.
