“Thanks to our simulations we know that if our theories of dark matter are correct then the Universe around us should be full of haloes that failed to make a galaxy.” – Professor Carlos Frenk

We already knew that the first generation of stars emitted intense radiation, heating intergalactic gas to temperatures hotter than the surface of the sun. After that, the gas is so hot that further star formation gets a lot more difficult, leaving haloes with little chance to form galaxies.” – Dr. Till Sawala
