dark matter - how little we know!
Two physicists sat down to talk about dark matter and what scientists hope to learn from CERN’s Large Hadron Collider in Switzerland.
What do we know about the universe?
5% of it is stuff we know
20% of it is dark matter (??)
75% of it we have no idea
Artist Jorge Cham from PHD Comics put the whole conversation to animation, very interesting!
Watch the movie : clicky
(Here's hoping this isn't too highbrow for NSR
)

"There are known knowns; there are things we know we know.
We also know there are known unknowns; that is to say we know there are some things we do not know.
But there are also unknown unknowns – the ones we don't know we don't know."

The scientists know a good bit about it all of course these days, but the more they find out, the more they cannot understand or explain. They have to have resort to theories which they have not been able to prove so far and find they have to invent something which they have never seen in an attempt to back up those theories.
I hope the LHC was not a waste of money anyway!

On topic, hopefully LHC will start to answer, or at least to start us down the road to answer, some very fundamental questions.

Les, I don't wish to drag this thread off topic, as it's interesting enough in it's own right, but considering your stance in the Heaven thread, dont you consider it a little ironic to lambast scientists for "inventing something they have never seen".....?

I am as interested as you are to see what they discover with the LHC, but I hope it does deliver the goods after all. It would be a terrible waste if it doesn't.
You should realise that my major interest during my education was in fact on the scientific side as it was during my whole career.
Les, not intentionally doing a Clarke!
