Title: Gaia is launched

I feel that I must point out that this Gaia is a satellite and not a wind turbine. ;D

Cool, from what I read they are hoping to get more information on how the dark matter holds "our" and all galaxies together, that in turn could shed some light on Dark Energy. Sometimes it does seem a waste of resources to mess about with these cosmological questions, but human nature being what it is I can't help being fascinated by all this stuff.

People are like yeast cells in a gallon jar of homebrew. All gobbling up the energy as fast as they can and polluting the environment. Then a couple of bright yeast cells say 'hey, why don't we spend a bit of sugar trying to work out how to get some more sugar before this lot runs out' and the others say 'Don't waste sugar, there won't be enough to go round'

On stargazing live last week, one of the guests commented that dark matter made up the majority of matter in the universe. What we are made of and understand as matter is a minority component. Therefore, we should try to understand what the majority constituent is. It ties in with all the work going on at CERN and other accelerator facilities. Personnaly, I  would prefer to spend a larger portion of the money pot on Nuclear Fusion R & D.

It was confirmed that I am basically 14 Bn years old, as are you lot too.

Pedants corner alert, only the Hydrogen, Helium and Lithium (if any) in your body will be primordial IE 14Bn years old, all the other stuff will have been made in the cores of subsequent stars which then gets spewed out of supernovea. Mind you cell apotosis would imply that most of your body is between 3 months and a year old, I think only some of our neurons stay with us for life.

Sooo in my case at least, most of my body is made of a load of second hand fall out somewhere between 3 months and 14Bn years old.

Yes, Desp, but where did all the raw material come from originally.  Yep, recycled from the primordial junk.  Good to know recycling has been around for longer than most think.  I suppose context  is everything, in this type of discussion.

The vid Earth from Space, posted by nickel2 (?) is one that is enlightening.  This one may well contribute to fusion development.  Who knows?

I feel so superior,

The raw material as I understand it is the energy of the big bang, don't ask where that came from whistle
 there's a thought Biff, you might get hunted down by the Martian pikeys trying to weigh you in horror:
