Most of Our Universe is Missing


8.30pm to 9.30pm SBS Sunday 29 October 2006

There was a time, not so long ago, when science seemed to understand how the universe worked. But recently things have started to unravel. According to this documentary, there is, it seems, a lot more to the universe than meets the eye and we only really know what 4% of the universe is made of. But if only 4% is made of atoms, what about the rest? From the most advanced deep space satellites to the world's deepest mines, cosmologists are on the dark matter trail. And the stakes are high; whoever finds the elusive dark stuff is virtually guaranteed a Nobel Prize, and could well have paved the way for the biggest prize of all - the elusive 'theory of everything'. Revolution is in the air as we visit the world's most powerful telescopes, fly through outer space, tour a virtual 'dark universe' and travel to the Earth's deepest mines to try to find the missing majority of what makes the universe

It was certainly a good program, laid out the history of the dark matter discoveries & debate very well !

Could not get my hands on a tv (in Sydney in half empty house) did anyone find out how the story ends outta anything I would have loved to see how this subject was presented under an hour. Oh well maybe next time.

I think that's the thing, Dennis. The story isn't over yet!

The program give a pretty succinct account of the history of the development of dark matter theory and the "standard model" with some counterpointing arguments from those who don't believe dark matter and dark energy is necessarily the answer. Some discussion on theories of Newton's laws of Gravitation needing tweaking as an alternative, for example. And also a bit of coverage of the search for neutralinos...

Interesting program Glen.

I wonder if someone can remember the name of the female professor appearing in the documentary I forgot to take note of her name. Her research on galaxies was quite fascinating and I would like to find out a little more about her on the net

Vera Rubin, Barb.

I too watched the presentation. I don't think I learned all that much - apart from some of the historical aspects - but it was pretty well organised, though a little fragmented at times. Still, given that this was compressed into around 40 to 45 minutes, it was well done.

I looked for 'Vera Rubin' on the Net ... the Wikipedia article is very short and many of the links seem to be outdated or have problems.

This seemed to be the best:

Thanks guys........great link Mike

Vera Rubin did some interesting work observing and clasifying super nova I think and was first to grasp the opportunity of using them as standard candles (maybe I am dreaming it is all very hazy) and I think she made the comment that she did not feel comfortable with the suggestion that dark matter could be a particle we can never see and hoped for a more suitable answer . It is annoying I cant recall the book or mag but there must be heaps of stuff out there as I have noticed her name in many locations, I recall she used a large refractor on a English Equatorial mount mmm I think heck the harder I try the dimmer it gets ...forget the dark matter problems I need to address the grey matter problem .
Anyways they are on the wrong track it is ""gravity rain"" they seek, if you can entertain ""gravity rain"" (gravity exsisting as the result of particle pressure acting as a pushing force not one of attraction) as a possibility it solves all those problems that dark matter and dark energy seek to explain...unfortunately I am the only person on the planet who understands how it does this so it may be a little while before it is taught in school
