Funny.. spell checked. Apparently gravitational means hrs irrational. Who knew?

New excuse for missing school assignments-
"Sorry, teacher...dark matter ate my homework."

Nah, dark matter is composed of all those missing left socks. . .

Lol. There is no dark matter. There are only false theories.

There is no dark matter.

Dark Matter kills you and removes the memory of you from everyone else.

One physicist is working on a theory that what others are calling "dark matter" is really just the side-effect of the quantization of inertia. He has shown that if you quantize the inertia in Einstein's equations you get the same (or at least similar) effects of suspecting there is some invisible dark matter.

However, astronomers have recently discovered galaxies which appear to have no dark matter. If the quantized inertia theory were correct, then it should be seen in all galaxies.

All in all very interesting stuff.

“Prove, or at least give me a plausibility argument that, say, old age isn’t caused by dark mater induced degradation.”

Well, there are a few animals (and plants/fungus) on the planet that don’t seem to die of old age. What is protecting them from the dark matter?

“Maybe it isn’t real, and it’s something made up to fit preexisting equations?”

I tend to agree. But I can also see how physicists might be inclined to leave no stones unturned before throwing under the bus a set of equations that have been working rather well.

Another possibility might be this. According to Einstein gravity is just the result of warped space, and matter is one thing that warps space, but maybe it isn’t the only thing that does the warping, or maybe space may be “naturally warped” causing what we observe.

“And they make fun of us for “making up” God. ;)”

Badabing! And there’s even more stuff at the other end of the spectrum, quantum mechanics, that stretches imagination and faith to the breaking point.

“Some of the comments about Dark Matter on this thread make Conservatives look stupid.”

You seriously need an injection of a sense of humor.

This is just BS extracted from the mind of nully, but, suppose there really is aether?

The only "proof" we have that there isn't is the Michelson–Morley experiment, an experiment that has only been done on the surface of the Earth. Suppose the aether swirls like the eddies around an oar or water flowing down a drain?

Stuff accumulates in these eddies/vortexes, every planet, every star and every galactic feature is defined by these eddies. If you look at an eddies in the 2 dimensional water model you can see striations on the walls, these correspond to the 3 dimensional arms in galaxies.

Back to Michelson–Morley experiment, done on the surface of the Earth only. The mass accumulation and the rotational velocity mirror the rotation of the aether vortex. The revolution of the Earth around the Sun tracks the swirl of the aether spinning around the Sun. After billions of years the interaction of aether and matter more or less reach an equilibrium. Surface velocity on a massive object is more or less zero, exactly as Michelson and Morley found. In effect, the were attempting to measure the velocity of the wind from a balloon floating freely in and with the breeze.

Why do some galaxies show anomalous rotation? The centers of most galaxies have a black hole where space-time spirals in. Does the fabric of space-time have a yield strength?

If so, as the black hole continues to gain mass, the very fabric of space-time stretches as the gravity well gets deeper and deeper. If at any point the strain exceeds the yield stress of space-time the funnel tears in two at that depth. Everything below that tear falls off into a separate universe.

Everything above? It rebounds. More space pours out of the old event horizon, as the mass that was holding it in place has budded off and as far as this universe can tell, simply ceased to exist. All the matter on the sidewalls above the new event horizon barfs out along with the space and forms the central bar seen on so many galaxies. For a time the bottom of the gravity well looks flat, and this flat gravitational gradient allows the matter to rotate around the core at the same rate rather than faster towards the center (which no longer has a steeper slope) than the edge.

You see a similar effect if you abruptly close a drain valve.

However, astronomers have recently discovered galaxies which appear to have no dark matter.

Their center black hole simply hasn't developed a steep enough stress gradient to bud off. Yet.
