Black holes 'came before galaxies' ~~>> did u know this ??

Astronomers claim to have finally solved the cosmic chicken-egg problem by concluding that black holes came before galaxies.

For several years, researchers have known galaxies and black holes must have co-evolved. If not all, at least our own -- the Milky Way -- is believed to have massive black holes at its cores.

Now, an international team, studying on the first billion years of the universe's history, has found that black holes predate galaxies.

"It looks like the black holes came first. The evidence is piling up," 'The Daily Telegraph' quoted Dr Chris Carilli from the US National Radio Astronomy Observatory, who led the team, as saying.

In their radio telescope observations, reaching back almost to the birth of the first galaxies, the team found that radio waves received from those and travelling at the speed of light were emitted only about a billion years after the Big Bang which started the universe.
