Dark Matter ? :-?  It can't be seen by any kind of telescope, no one knows what it is, but they say it has to exist and there are various large experiments etc searching for it.

...and now some experts say there's something called Dark Energy...and this is something they really do not like. Apparently it is not good  :o

then multiply that by the age of the sun.....say 5 billion years ago

I found it fascinating! 8-) 8-) :y :y

The best bit for me was the description of how in (I think) 5 billion years time the Sun will become a Red Giant star, expanding some 200 times it's existing size, taking out the Earth in the process, before the Sun implodes. 8-) 8-)

How's that for global warming!! :D :D ;)
