The first stars in the universe may have been very different from the stars we see today, yet they may hold clues to understanding some of the mysterious features of the universe. These "dark stars," first theorized in 2007, could grow to be much larger than modern stars, and would be powered by dark matter particles that annihilate inside them, rather than by nuclear fusion. In the early universe, dark stars would have emitted visible light like the Sun, but today their light would be redshifted into the infrared range by the time it reaches us, and so dark stars would be invisible to the naked eye.

Inside these stars, weakly interacting massive particles (WIMPs), a candidate for dark matter, could accumulate. Since WIMPs can be their own antiparticles, they could annihilate to produce a heat source. If the dark matter density was high enough, this heating would dominate over other heating (or cooling) mechanisms, such as nuclear fusion. Compared with fusion, WIMP annihilation is a very efficient power source, so that only a small amount of dark matter is required to power the star.

They really cannot figure it out can they?

They are so utterly confused and bewildered by the daunting questions about the universe.

I mean look at them, they are chasing fairy dust. lol

Dark matter did it! Thats like hardly any better than telling me God did it.

Oh well maybe one day they will come up with an explanation.

Dark matter theory is starting to lose it's usefulness.

Perhaps we should come up with something new to explain things? And maybe the so called "scientific community" should be alot more open to peoples ideas?

IMHO every person in the world who wants to think about it needs to suggest ideas. This will give us the best odds of getting novel answers.

Did you even read the article muzzleflash? They're not saying how the universe started, merely explaining stars that are fueled by dark matter that may have been the some of the first stars born and how they compare with modern stars

muzzleflash is quite correct in his views ... we still have NO idea whatsoever what "dark matter", assuming it even exists, is composed off and what it's properties may be.
So to postulate early stars being composed/fueled with dark matter is basically just whistling in the dark and generating wild sounding possibilities and then following up with unprovable statements such as "may hold clues to features of the universe".

Thats about as valid as me stating that gravity is produced by dark matter and that may also hold clues to features of the universe.
