How Dark Matter Might Have Snuffed Out the First Stars »

A team of researchers is proposing that massive quantities of dark matter formed dark stars in the early Universe, preventing the first generations of stars from entering their main sequence stage.

Once again, blame it on the blacks. Throughout the entire universe, it's the dark ones keeping the white ones from progressing

Shouldn't this be in the humor catagory ?
Anyway no such thing as dark matter, just an electric universe.....">http://www.thunderbolts.info/">universe.....

Okay buddy then let's support your G*d theory. Is g*d a white or black star? or maybe just the space between the stars... I know... I do. I DO!! G*d is the space between the stars that are feeding upon each other... kinda like the great pacifist unifier of the universe.

FooFighter - Well, you may be winning - I'm am getting bored now following your threads. You have even begun to repeat your slogans. You are boring, because there's no real point you make. Now, being a fine young lady as you are, I'm sure that your keep track of the family tree in the family Bible. Which one of your relatives was still making making maps insisting that the world was flat in 1900?

General Relativity Resolves Galactic Rotation Without Exotic Dark Matter
Authors: F. I. Cooperstock, S. Tieu
(Submitted on 26 Jul 2005)

Abstract: A galaxy is modeled as a stationary axially symmetric pressure-free fluid in general relativity. For the weak gravitational fields under consideration, the field equations and the equations of motion ultimately lead to one linear and one nonlinear equation relating the angular velocity to the fluid density. It is shown that the rotation curves for the Milky Way, NGC 3031, NGC 3198 and NGC 7331 are consistent with the mass density distributions of the visible matter concentrated in flattened disks. Thus the need for a massive halo of exotic dark matter is removed. For these galaxies we determine the mass density for the luminous threshold as 10^{-21.75} kg.m$^{-3}.

A long time ago before there were CD's there were LP's and if you listened to music with headphones on; between songs was dark matter and a void and it was scarey,then...all was cool again till the next void.

Dark star crashes
pouring its light
into ashes
Reason tatters
the forces tear loose
from the axis
Searchlight casting
for faults in the
clouds of delusion
shall we go,
you and I
While we can?
Through
the transitive nightfall
of diamonds
Mirror shatters
in formless reflections
of matter
Glass hand dissolving
to ice petal flowers
revolving
Lady in velvet
recedes
in the nights of goodbye
Shall we go,
you and I
While we can?
Through
the transitive nightfall
of diamonds
spinning a set the stars through which the tattered tales of axis roll about the waxen wind of never set to motion in the unbecoming round about the reason hardly matters nor the wise through which the stars were set in spin

If stars are created by gravity, as the paper indicated, and gravity was not able to take hold in the early universe then how would a dark star evolve without gravity?

If the only way you could see out of your room, for your entire life, was with binoculars and cameras mounted on remote control devices; do you think you would be able to give an accurate description of how the world looked, acted and operated?
explain an airport through the eyes of a camera mounted on a remote control car. the ocean? explain how a nuclear reactor works by only observing its operation from a distance.
are you seriously going to tell me that scientists know how much matter is in the universe? or if some of it is unaccounted for? unaccounted for? by what accounting method exactly if we cant get further than the moon with any seriousness?
a nobel prize was awarded to the men who promote dark matter not long after these men published this math supporting general relativity on a macro scale. and the scientific community ignored ot b/c they were too heavily invested in god, oops I mean dark matter.

sorry capn. not trying to come off as a hater. I love science, I'm just a little passionate about the fact that dark matter and string theory have no more support than Intel. Design, yet they are considered sciences only because they were invented by scientists.

I thought "dark matter" was when a person was ambivalent about something (and basically thought "It doesn't matter.")
