Primordial black holes would have formed in the very early Universe with a wide range of masses, from some as small as an asteroid up to thousands of solar masses. They could constitute an important component of dark matter, as well as being the seeds for the supermassive black holes at th...
Some astronomers have even considered whether Planet Nine, a hypothetical planet far out in the solar system that may be responsible for irregularities seen in the orbits of our known planets, could be a "baby" black hole in the mass range of what could be a primordial black hole. Bu...
Unfortunately, that vision is still a moonshot, with cost estimates breaking the $1 billion mark — that is, if it's even feasible from a technological standpoint in the first place. READ MORE: Scientists propose plan to determine if Planet Nine is a primordial black hole [Harvard] More on...
How Do Black Holes Form? Primordial black holes are thought to have formed in the early universe, soon after the big bang. Stellar black holes formwhen the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part...
Detecting the primordial black holes that could be today's dark matter Jul 14, 2010 #2 zhermes 1,253 3 Interesting idea brainstorm, but there's one piece missing: its not JUST the act of infalling that creates the jets. Whats happening is that, lots and lots of dust and gas and...
In 2000 the same analogy was used to establish the robustness of the spectrum of primordial density fluctuations in inflationary models. This analogy is currently stimulating research for experimenting Hawking radiation. Finally it could also be a useful guide for going beyond the semi-classical ...

How is anti matter created? If space is curved, what fabric/material is space? If the universe is ever-expanding, couldn't there be multiple universes expanding into each other? What is the main source in the universe for the origin of hydrogen? a. primordial nucleosynthesis b. fusion in ...
in the centers of most large galaxies have masses which can masses of millions to billions of solar masses. The formation of these supermassive black holes is currently under research and is not yet well understood. There may also be primordial black holes which were formed in...
