Dark MatterGalaxy

[Geniere]

The faster than expected orbital speed of stars in a galaxy is a problematic issue for astronomers. To explain the phenomenon, Dark Matter is proposed to make up for the missing mass. It would also be possible for dark matter to exist in a galactic formation without any stars; a galaxy containing only Dark
Matter and Hydrogen gas.

Such a galaxy may have been found:

Ty for the post...I was wondering when they were going to find one of these.

I still don't buy dark matter, I remember a guy who just said a simple adjustment in the calculations of the movement of galaxies would solve the whole process. Remember Occam's Razor.

OMG your friend is a genius!

Einstein did the same thing before he realised it was a mistake. You have this simple, beautiful equation, that can explained everything else in the universe... but to explain one phenomena, you have to add a constant to it, and although it 'works', it doesn't make sense.

Einstein never regarded his quest for the ultimate theory of everything as a mistake. In fact the only thing that he worked on that he did regard as a mistake was Quantum physics, I think.

And simple equations do work, on the large scale. E=MC squared still applies.

I don't know if I can buy this "dark matter" that no one can even detect, and only exists because scientists can't think of anything better.

Do yourself a favor and do a search for cosmological constant.

Which Einstein folly are you talking about? Einstein predicted in his calculations, the expanding galaxy, but was religious enough to NOT believe in his accuracy, and went so far as to add a constant to his equations that made the universe 'static' again. When Edwin Hubble discovered and named Red-shift and recorded the recession of several galaxies, Einstein conceeded and revised his equations. I did a paper on the Hubble Telescope and went into Dr. Hubble's background and read a bunch of stuff like that.

:roll:

Alright, maybe i'll explain this in simple terms: Einstein fudged with his equations by adding a constant in to explain a phenomena that he observed, but was conflicting with his equations. This is the exact same thing. The math is telling us we are missing a lot of matter in the universe, but we don't see that matter. Adding in a constant will make the math agree with what we see, but it's a moronic way of doing it. Do we want to fiddle with the math so that it agrees with what we see? Do i really need to go on and explain why we don't?

no, because it's the same reason i read brian greene and have some understand of how much we DON'T know, at least as a species, short of maybe the top 100 minds in teh world. I wasn't trying to counter your opinions, merely to inject what i'd read to maybe clarify for anybody who needed a different view.

IMHO I dont think any of it will make sense to anyone until we actually make the glorious trip to see it in person. In the meantime we can all make good arguments... hehe as this seems to be a common "highly technical" topic
