WebOct 4, 2013 · Primoridial black holes can be found (hypothetically; there is no experimental evidence yet) of any small size above the Planck mass. Stellar black holes, however, cannot have a mass below the TOV limit (1.5 to 3 solar masses) There does seem to be an upper limit 1 of 50 billion solar masses.
What is a black hole event horizon (and what happens there)? - Space.com
WebThe event horizon of a black hole – otherwise known as its surface – is the boundary where the escape velocity is higher than the speed of light. As this represents the universe’s speed limit, matter falls into the black hole but fails to escape back out of it. Continue reading to discover why we call this area the event horizon and how ...

WebGiven the success of understanding the EVH limit of AdS 5 BPS black holes, it is interesting to know whether the method can also be used to study BPS black hole in other dimensions. The entropy-temperature scaling de nition (1.1) of the EVH black holes requires knowledge about non-extremal AdS geometries at strong coupling. Lim- WebJul 6, 2024 · No, there is no theoretical maximum limit for the mass of a black hole. In practice, one could argue that a black hole's mass can't exceed the total mass of the Universe, but defining what one actually means by "total mass of the Universe would be complicated". If two black holes merge, they simply form a larger black hole.
