Universe’s first stars may have been ‘dark stars’


The universe’s first stars may have been bloated behemoths powered by dark matter, suggests an intriguing, if speculative, new study. These ‘dark stars’ might have delayed the creation of heavy elements, which make up everything from planets to people, as well as cosmic reionisation, which made the universe transparent to light billions of years ago. Theorists believe the first stars formed in cradles of dark matter, condensing from clouds of gas until their cores became so dense that nuclear fusion ignited, preventing the cores from collapsing further. This could heat up the cloud so much that it would stop contracting, so that it was supported by the annihilation of dark matter rather than by nuclear fusion, like normal stars. Such a ‘dark star’ would be about as massive as the Sun and would glow at infrared wavelengths. But it would be much larger – depending on the mass of the neutralino used, the star could span anywhere from the distance between the Sun and Uranus in our solar system to nearly 60 times that size.

    The problem with the Big Bang Theory is that the Big Bang didn’t happen. What did happen, is happening and will happen, is Galaxy Spin.
    Like satellites around planets, and planets around stars, and stars around the galaxy, the galaxies themselves are turning in orbit.
    The Big Bang is based on two premises. One, there is cosmic background radiation everywhere; and two, the galaxies are going away from each other causing their light to be red shifted.
    With billions of stellar furnaces out there it would be surprising if there weren’t background radiation. As for the galaxies flying off to Neverland as the Big Bang tells you, it’s not happening.
    The red shift is caused because our galaxy in its’ orbit travels faster than some, thus the red shift, and slower than others, again the red shift.
    But there are also blue shift galaxies, ones that are coming toward us. With everything being blown apart by the Big Bang, how do they explain that? Well, they don’t. What is happening is we are gaining on some detected galaxies that are in an outer orbit, thus the blue shift, and some on an inside orbit are gaining on us, again the blue shift.
    If you believe in the Big Bang theory you have to believe in large sums of dark matter and dark energy. Dark matter because the light from distant galaxies is shifting; and something has to be making it shift. Dark energy because as the galaxies go away from each other they are accelerating, and, well there must be some energy causing them to accelerate. Nobody seems to know what dark matter and dark energy is.
    There is no dark matter. What is causing the light to shift is that the galaxies are turning in their orbit around a central unknown I call Tipperary because it’s a long, long way to go. And as for the galaxies accelerating to infinity and … They are not.
    This is what’s happening. Say you are in a car going ten miles an hour, and another car next to you is going ten miles an hour. There is no acceleration going on. But say the car next to you takes an off ramp. Then suddenly it appears to one another that the other car is going faster and faster, even though you are still both going ten miles an hour. Every galaxy is on its own off ramp appearing to be accelerating, but it’s still going its same orbital speed.
    Sexy stuff; dark matter and dark energy. I wanted to put them in my theory, but I didn’t know what they were either.
    How far away is this central unknown, Tipperary. Your guess is as good as mine. If we compare it to our place in the galaxy: the distance to the nearest star; Proxima Centauri is 4.2 light years. The distance to the center of our galaxy 182,400 light years, which gives a multiplication factor of 43,428. The distance to the nearest galaxy; Andromeda is 2.2 million light years. Multiplying 2.2 million by 43,428 gives a distance to the center of galaxy spin as 95.5 billion light years. It could be a lot closer or a lot further. As of now we can only see less than fifteen billion light years; we are going to need better glasses before we see Tipperary.
    I call this galaxy spin entity a Whirly; I call this Whirly we are in the “S.R.T.E. Whirly”. Are there other Whirlies out there? Logically. All spinning around something even bigger.
    It’s time to place the Big Bang theory where it belongs, next to the flat earth theory. Thank You.
    If you would like to see my demonstration, it is on YouTube as (Big Bang A Bust). I would appreciate any comments (rants or raves) you may have. My email address is galaxyspin@yahoo.com.
    Sincerely, Jeff Mitchell (The Galaxy Spin Guy)

    Wow that is an interesting theory and one that i had not thought of yet. It is true that all we can perceive is called the visible universe. Therefore there is stuff out there whose light has not had enough time to travel to us yet from across the cosmos. If anything is for certain all things seem to be like gyroscopes to me. Electrons zip around atoms, planets around stars, stars around a galaxy, galaxies around super clusters so why stop there super clusters spin around tipperary. I’m no expert, but I would like to see how this fits in with the other theories out there. After all everything is relative!!!!
