A fantastic Horizon (one of my favourites) that looks into the research on Dark Matter (with a twist of comedy to it!)...We know what 4% of the Universe is made of. But what about the rest?
There was a time, not so long ago, when science seemed to understand how the universe worked. Everything – us, the Earth, the stars and even exotic-sounding supernovae – was made of atoms which were all created at time-zero: the Big Bang. In between the atoms was nothing, a void: quite literally, 'space'.
But recently things have started to unravel. There is, it seems, a lot more to the universe than meets the eye. According to the best estimates, we only really know what about 4% of it is made of. But if only 4% is made of atoms, what about the rest? The rest is made of mysterious entities about which very little is understood, with equally mysterious names: dark matter and dark energy.

Farhad2000Quite frankly I find it very hard to buy the idea of Dark Matter. Yet I cannot really counter the scientific evidence provided.
fireflyDid they check under the sofa cushions? That's where I find a lot of the stuff that I've lost!
HistNerdThis stuff is wild, we just started it today in my course on Astronomy and Cosmology. Another thing that blows my mind is that we can't see the entire universe, because at the beginning of the Big Bang, it moved faster than the speed of light. This is cool stuff!
