What On Earth Is Wrong With Gravity? SBS Doco

[Enchilada]

Just a quick note.

Tonight on free-to-air SBS at 7.30pm is science doco about gravity.

This is an English BBC Horizon programme made in 2008

Heaps related to astronomy...

Looks interesting. :thumbsup:

What on Earth is wrong with gravity??

Well, everywhere else gravity is exciting and does bad things but here it just sucks:P:P:D:D

mmmm gravity does not suck in my view:eyepop: both from the aspect of being an interesting subject to think upon and from the mechanical opperation ...

no gravity does not suck :D..

well if we believed that gravity did suck we would need to introduce wild notions to explain why the outter stars of galaxies move faster than our current sums say they should...and we would have to entertain these wild notions if we are to fit the sums to the observations...

perhaps we would need to imagine some form of matter that although undetectable via the normal means would show its presence by the gravitational influences we detect, that without this new matter would make our sums dubious ...

if we elected to find gravity did suck we could content ourselves that our math did agree our observations
we could say gravity sucks or we could simply realise gravity does not suck which is a simple choice that gives on the one hand an impossible notion of how the universe works or on the other a reasonable explanation requiring a universe where we can observe all there is without further nonsence requiring hidden matter to make up some 80-90% of our universe...

if it did believe gravity sucks we would have to tolerate the stupidity of a universe where most of the matter will remain hidden from us..if they ever find a graviton at the end of a piece of string it will be found to push;)...if we find the HB it will be found to push:P ..how else could these things work if not by push:shrug:...now none of the science as to strings or HB's suck so why would gravity suck:D?

I heard about the show from a nice lady at the pub but we got thrown out before it came on...the show that is:D

Thanks for the "heads up!", Enchilada. I caught it and enjoyed it.

:doh: I missed it again :rolleyes:

Very ordinary stuff with a few clangers in the mix.

(For example the time correction factor for GPS satellites as "proof" of space time curvature is wrong.)

This what happens when you get a particle physicist attempting to explain GR.:)
