Dark matter at least accounts for a discrepancy - sure, I don't accept its existence, but at least it has that going for it haha
If you don't people making fun of your beliefs, don't have such funny beliefs. - - - Updated - - - Dark matter. Gravitational lensing. Keep up with the times.
Gravitational lensing is the discrepancy. Just because your forehead is hot doesn't mean you have a cold.
The dependency is the fact that galaxies do not fly apart by their own momentum. Gravitational lensing is a means of observing dark matter.
Yes, but we have no way of knowing that it's actually any sort of matter that's causing it. Our theories could simply be wrong.
True. But since it's behaving exactly like gravity would if there were a large mass, the most logical conclusion is that there is a mass causing it, rather than invent a more exotic theory out of whole cloth.
I find this rather ironic. German philosopher Friedrich Nietzsche once proclaimed... "God is dead." Meaning humankind had no need for deities or supernatural mumbo-jumbo...God is irrelevant in modern society. Nietzsche lived a long time ago, in the 19th century and he's long since dead himself. Apparently he can't rest in peace though... Source: http://www.spiegel.de/international...sal-threatens-nietzsche-s-grave-a-543222.html Rest in Peace...Friedrich Well maybe not.
I'm sure Nietsche wouldn't care. I'm not sure believers care, either. You know the story of the catacombs in Paris, right? How they fill them with the bones of bodies removed from full graveyards so they can reuse the graveyards for new burials? Moving bodies so the land can be used for other purposes is a long tradition, even for the religious.
He has a nice tombstone, in a nice quiet cemetery in a quaint German town. I think it's mildly amusing that the very progress he talked about, replacing the need for God... is infringing on his final resting place. He was a nihlist afterall...he thought life held no real meaning or purpose... that our lives mean nothing, we fade into oblivion. They found coal in the area...and progress will roll over his legacy like a bulldozer; literally a bulldozer. Sorry the irony escapes you...
I guess I don't see the irony. He wouldn't care, so it totally wouldn't be an issue that his gravesite is being disturbed. For me, the ironic part is that he had a nice big gravesite in the first place. But then, those are for the survivors, not the dead.
It's regarded as an historic site...alot of people who admire his philosphy, which is often associated with Nihlism...a philosophy with a foundation based in atheism, visit the grave. Auf Wiedersehen Coal is more important than a 19th century philosopher. Although the article cited is from 5 years ago, so I don't know if the site was preserved or not. Perhaps it's just a question of time.
What else would cause a curvature in spacetime that would act exactly like matter? You are splitting hairs over a non-issue.
If it walks like a talks and talks like a duck.... You are splitting hairs over nothing. - - - Updated - - - It exists because it has been observed. Keep up with the times.
show it and prove it's not just a large mass of hydrogen that hasn't formed into stars...or even strings.
you're the one with the faith in an object that was invented to fit the present model of the universe. it's no different than you asking theists to prove god exists.
What faith is required? Galaxies are heavier than they should be, and oh my god Batman, there is a veil of invisible matter surrounding galaxies. How is faith related to observational evidence? Thing is, you don't understand the subject, I suggest you stop acting like an authority on it. - - - Updated - - - Dark Matter: Strong Gravitational Lensing http://lsst.org/lsst/science/scientist_dark_matter Whoops!
yeah, i'll take the word of someone that can't post a link after +10k posts. the facts remain, transparent is not invisiable and mass can only be estimated...and dark matter isn't theorized to be clumped around other bodies, just occupying the vast emptness that is space.
Dark matter is not theorized to be clumped together? Then why is it theorized that dark matter clumps around galaxies? http://physicsworld.com/cws/article/news/2013/jun/03/do-dark-matter-discs-envelop-galaxies Dark Matter Clumps This map shows the distribution of dark matter in a portion of our universe. It was created with the help of "weak gravitational lensing" -- a natural phenomenon that occurs when light from distant galaxies is slightly warped by the mass of galaxies and clumps of dark matter in the foreground. Astronomers use complex imaging software to analyze images of these warped galaxies, and ultimately to create dark matter maps like this one. This map derives from the largest ever survey performed by NASA's Hubble Space Telescope -- the Cosmic Evolution Survey, or COSMOS. http://www.nasa.gov/topics/universe/features/great20101206-i.html http://www.space.com/3319-astronomers-create-3d-map-dark-matter.html Educate yourself before ever commenting on this subject again.
do you have the slightest understanding of what your saying? dark matter allegedly has gravity, and clumps around other matter, but doesn't form cohesive bodies because it is invisible and can't be touched?....yeah, your faith in an invention of imagination is up there past the fundies.
Dark matter without gravity is not dark matter now is it? Please provide evidence that dark matter does not clump around matter.
Theories explain facts. That the facts exist isn't evidence of your explanation. That's what I'm saying. General relativity wasn't proven by the fact that it fit our observations, it became accepted by making very accurate predictions (for example, the precession of Mercury). If Dark Matter can do the same, and hence move from the "useful hypothesis that fits the observations" column to the "has made undeniably accurate predictions" category, then we'll be onto something.
