A long - standing question in astrophysics is whether the universe's very first black holes came into existence less than a second after the Big Bang or whether they formed only millions of years later during the deaths of the earliest stars.

Not exact matches

With the black hole merger, general relativity has passed the first such test, says Rainer Weiss, a physicist at the Massachusetts Institute of Technology (MIT) in Cambridge, who came up with the original idea for LIGO.

Last week at the American Astronomical Society's meeting, astronomers announced the detection of a second type of radio static from the heavens, and although it may not come from an era quite as ancient as TV snow does, it may probe the period immediately afterward — an equally mysterious time when the first stars and black holes were lighting up.

«In essence, this black hole has not had much to feed on for a while, and suddenly along comes an unlucky star full of matter,» says Dheeraj Pasham, the paper's first author and a postdoc in MIT's Kavli Institute for Astrophysics and Space Research.

Galaxies or black holes: Which came first?

MAKING WAVES The first gravitational wave signal detected by LIGO came from the merger of two black holes spiraling inward, as depicted in this numerical simulation.

Dark matter hitting black holes could be the source of some fast radio bursts — mysterious blasts of radio waves that come from billions of light years away, first detected 10 years ago.

But astronomers have long wondered which came first, the black holes or the stars.

Studying these quasars will also deepen our understanding of why nearly all galaxies have supermassive black holes at their cores, begging the chicken - or - the - egg question of which came first, the galaxies themselves or the black holes, or whether the two arose interrelatedly.

Other stellar - mass black holes — such as the one in Cygnus X-1, the first black hole found — came to attention because hot gas swirling into the black holes emits x-rays.

Some of the strange mathematical properties of black holes, coming from Karl Schwarzschild's first solution of the Einstein field equations of general relativity in 1915, still puzzle the scientists.

The very first gravitational waves measured directly came from two merging massive black holes — of all things!?

Webb's investigations of our own black hole and the relationship between black holes and galaxy evolution could help solve a cosmic chicken - and - egg problem: Did black holes come first and galaxies form around them, did galaxies form first and develop black holes, or did the galaxies and black holes develop together?

If more such objects are detected, it would not just help scientists create a better model of how the first supermassive black holes in the universe came to be, but also help understand how the one in the Milky Way's heart formed and evolved.
