Mini blackholes!Sounds cute right?
What do you think when you hear the name blackhole?Monsters that gobble up everything with a singularity in the centre and that are surrounded by an event horizon Once something comes closer to the black hole than the radius of the event horizon

it is not able to leave: even light can’t escape. So how would a ‘mini’ one be different from their giant cousins lurking out there in space?
Producing black holes turns out to be about mass (energy):

squeeze mass into a sphere with a radius equal to what’s known as the ‘Schwarzschild radius’ - a threshold beyond which gravity causes an object of a certain density to collapse in on itself - and a black hole will form.

For example, in order to form a black hole out of our Earth,you would need to squeeze its mass into a sphere about the size of a marble(radius 8.9 mm).By comparison the Schwarzschild radius of the sun is about 3 km.According to Stephen Hawking, they will not be that black in fact

They will evaporate with time approximately following a black body radiation spectrum. The evaporation rate will be inversely proportional to the black hole mass.Astronomical black holes are so massive that their evaporation rate is negligible

In contrast, mini black holes are hot: unimaginably hot. The core of our Sun is at around 15,000,000 degrees Kelvin - to get close to the temperature of a mini black hole you would need to add another 42 zeroes.’

What this incredible temperature means is that mini black holes of tiny mass evaporate into the far, far colder space around them almost infinitely fastTheir expected lifetime is around one octillionth of a nanosecond so that they pop out of existence aga as soon as they are born

Now you're reading this thread in your phone on twitter with the help of WiFi. Ever thought of how WiFi came into existence? Answer is Blackholes!! Yes those monsters aren't that bad after all.

How did the pure research of searching for black holes give us WiFi?This begins back in 1974, when Stephen Hawking theorised that under certain circumstances, small black holes might "evaporate" — and simultaneously emit radio signals.

These hypothesised black holes were about the mass of Mount Everest, and smaller than an atom. Soon after, the physicist and engineer John O'Sullivan tried to find these signals.If these small black holes were evaporating, they would emit radio signals as they vanished.

But because of their great distance from us, these signals would be hard to identify because they would be tiny by the time they arrived, as well being buried in a background of louder 'noise'. Furthermore, this tiny signal would be 'smeared'
