It all starts with a curiosity; primordial black holes




There is a theory that states that primordial black holes may exist, primordial black holes are a theoretical object that has not yet been discovered and they would all form if they had all emerged during the Big Bang.


What is the difference between normal black holes, which form when a massive star collapses, and that primordial black holes can be of almost any size, so originally a black hole could have arisen from the mass of a human being or a cow or a mountain or one of the earth's mass.


The point is that of the less mass of the planet Ceres, which is about 1000 km in diameter, none of those less than that mass should exist, they are theoretical objects, but none should exist anymore,


There is new research this week that bridges that issue, and mentions that none should exist due to Hawking radiation. Stephen Hawking theorized that black holes evaporate over time due to an effect between the event horizon and they lose mass over time, the point is that small black holes lose and evaporate more quickly than large ones, a large one can live billions of millions, we would understand it for eternity, but a small hole with the mass of a human being that could having formed during the Big Bang those last very little, a few million years at most.


There may be primordial black holes of the mass of the moon or the mass of the Earth and those can be around, in fact, there is a theory that maintains that dark matter would be formed by this type of primordial black holes, the problem is Although none have been discovered yet, there may be some walking around the solar system.
