Great minds don't need to be good at math. Now a great mind that also was one of the deepest theoretical physicists of all times being bad at math just don't make much sense.

Well, yes, there is this brown crispy patch just here but that could also be due to sitting on the toaster.

If you eat dietary charcoal it gives you dark matter. 😕

Is it real or is MOND a better explanation of the strange behaviour of galaxies? Are physicists just making it up as they go along or is there some truth in this dark matter malarkey?

I have to declare an interest here, I am currently researching how stars move in galaxies and what might be causing them to move too fast. The favoured explanation is dark matter but there is currently no real evidence for the existence of dark matter.
haha so i take it you saw the episode of the "futurama"? yeah, it was awesome, i love the little black monkey dude

How do you measure the speed at which stars are moving using MOND? It's been a while, but I understood Newton to have used free bodies moving in straight lines as his clock, yet there are no free bodies in the universe upon which to base such a clock.


As an aside, i'd be interested in knowing how one can determine accurately the speed of a moving object since relativity suggests this is very difficult for an observer to gauge using data from only one fixed point in space.
