(Phys.org) -- A trio of astrophysicists is theorizing that the reason that there is not a larger variety of black hole sizes in the known universe is because those that were spawned first heated up the universe to the extent that it stunted the growth of others. The team members: Takamitsu Tanaka, Rosalba Perna and Zoltán Haiman outline their ideas in their paper theyve uploaded to the preprint arXiv. In it they suggest that the black holes that formed soonest after the Big Band, pulled in enormous quantities of gas and emitted huge amounts of x-rays; enough they say to heat up the universe, preventing other black holes from growing larger.
