Completed in 1980 but operational before then, the VLA was behind the discoveries of water ice on Mercury; the complex region surrounding Sagittarius A *, the black hole at the core of the Milky Way galaxy; and it helped astronomers identify a distant galaxy already pumping out stars less than a billion years after the big bang.
Extragalactic neutrinos come from elementary particles that collided shortly after the big bang or crashed into each other while orbiting massive objects like black holes.
That would be big enough to see gravitational waves emitted by any merging supermassive black holes that may have existed around the time when the universe's first stars began to shine, about a hundred million years after the big bang.
Big black holes from just after the big bang couldn't have formed the way modern ones do - but they could come from the collapse of the largest stars eBig black holes from just after the big bang couldn't have formed the way modern ones do - but they could come from the collapse of the largest stars ebig bang couldn't have formed the way modern ones do - but they could come from the collapse of the largest stars ever
A hidden population of black holes born less than one second after the big bang could solve the mystery of dark matter
A gargantuan black hole has been spotted voraciously devouring material just 770 million years after the big bang
Black holes that might have been created shortly after the big bang could constitute the universe's hidden mass, but they would have to exist in such abundance that we would likely have already discovered them through other means.
«This chicken - and - egg problem of what was there first, the galaxy or the black hole, has been pushed all the way to the edge of the universe,» Yale University astrophysicist Kevin Schawinski said in a June 15 press conference at NASA Headquarters in Washington, D.C. Schawinski was part of a team of researchers that used two renowned orbiting observatories, the Hubble Space Telescope and the Chandra X-Ray Observatory, to identify a population of black holes in galaxies at redshift 6, which corresponds to a time about 950 million years after the big bang.
But recently, a survey has found several quasars — bright cores of galaxies, powered by matter falling into a supermassive black hole — that existed less than a billion years after the big bang.
As we noted, the LHC will not destroy the world and as George Musser wrote to me after we recorded the interview, «I said something to the effect that scientists had stocked [stoked] concerns about black holes by saying the LHC would create particles not seen since the big bang, but those particles have been seen since the big bang, namely in natural processes such as cosmic ray collisions; therefore if black holes posed a threat, the universe would already be a goner.»
Just a billion years after the big bang, supermassive black holes as much as 10 billion times the mass of the sun were making their presence felt in the universe.
«If we go back to the very earliest point in our universe, just after the big bang, there seems to have always been a strong correlation between black holes and galaxies.
Here's the problem for those who believe a big bang preceded the formation of black holes, stars, and galaxies: black holes are too small to affect something as huge as a galaxy that formed long after the universe expanded, and there is no reason a galaxy should form a large central black hole.
