Do black holes cause dark matter?
Primordial black holes, if they exist, were likely created in vast numbers in the first second of the Big Bang about 13.77 billion years ago. If they did exist, these ancient black holes could make up the immense halos of “dark matter” that fringe galaxies, some astrophysicists think.
Do black holes radiate dark energy?
While dark matter are now widely thought to be some form of massive exotic particles, such as primordial black hole formed within the first several second of our universe [3], it seems that black holes have nothing to do with dark energy because dark energy is not affected by gravity, no matter what size the black hole …
What do black holes radiate?
As this article will show, due to vacuum fluctuations of quantum fields in the vicinity of its surface (the so-called event horizon), the black hole emits particles, such as photons (particles of light), neutrinos and others. Black holes, therefore, are not completely black!
Could dark matter actually just be black holes?
An analysis of ripples in space-time suggests the mysterious substance consists of primordial black holes. Dark matter, the mysterious substance that exerts gravitational pull but emits no light, might really consist of vast concentrations of ancient black holes created at the very start of the universe, according to a new study.
Is dark matter composed of primordial black holes?
The most interesting theory is that dark matter is composed of primordial black holes. Researchers looked at the early universe for clues about primordial black holes during the study. They believe the early universe was so dense that any positive density fluctuation of more than 50 percent would create a black hole.
Could a black hole be antimatter or dark energy?
a liquid – with a small volume (antimatter) – into something which is equivalent to a gas with a large volume (dark energy).Dark energy creation in a black hole could stop a singularity from forming in the hole.But it could just be the expansion of intergalactic space lowering the pressure existing dark energy exerts on antimatter, located in intergalactic space, that allows more antimatter to evaporate and form new dark energy.
Is there dark matter present around a black hole?
Dark matter and black holes are some of the most mysterious things in the Universe, so a connection between the two is absolutely thrilling . In a new study, astronomers report a strange link between the amount of dark matter in a galaxy and the size of its supermassive black hole. That’s an amazing new black hole fact!
