One of the topics regularly discussed by the US conspiracy community is all sorts of scientific discoveries with which scientists from time to time shock the public. Especially people are strained by the threat of scientists with the appearance of black holes in certain places, for example, at the CERN particle accelerator.
And so, as recently the astonished world was discovered by astronomical adepts - a black hole can be generated even by a rather powerful sound with a force of only … 1100 decibels.
At first glance, some kind of dramatic error crept into the message of astronomers. Maybe a hundred after a thousand decibels means orders?
Unfortunately, there is actually no error, since decibels are a logarithmic scale. This means that 20 decibels is not 2 times more powerful than 10 decibels, but 10 times more powerful. Accordingly, 30 decibels is 10 times more powerful than 20 decibels, and 40 decibels is 10 times more powerful than 30 decibels. Every time the decibel number is increased by 10, the sound power is multiplied by 10.
If, without remembering the logarithms, we estimate the sound at 1100 decibels according to the loudness tables, then 1100 decibels is, as it were, not so much - ten times stronger than a jet plane taking off. However, in fact, in order to add another 950 decibels to the 150 decibels of the aircraft, 95 zeros will have to be attributed to the sound power of the aircraft taking off. This, as mathematicians say, is quite a lot.
The largest number in existence is Googol, 10 (to the power of 100) - ten to the hundredth power or ten and 100 more zeros. In English, Googol is spelled Googol and the well-known company Google wanted to call itself just that. Unfortunately, the name of the brand was taken by some people that no one remembers now, so Googol became Google.
10 (to the power of 100) is a very, very large number. For example, atoms in the visible universe are assumed to be only 10 (to the power of 81). That is, it is much less than the Googol number, so how to apply it mathematicians puzzled for decades until they were helped by astrophysicists.

Everyone knows the formula E = mc2. This formula implies that energy is in some way equivalent to mass. Therefore, if an energy bunch is created at some point in space, for example, a sound wave, this volume of energy can be considered as a kind of mass.
In particular, if you create a sound wave with an energy of 10 (to the power of 98) watts / meter2 (which is equivalent to a sound of 1100 decibels), a cubic meter of air in which such a wave occurs will be compressed into the microscopic Schwarzschild sphere necessary for this mass, which will be so massive, which will instantly increase its size to the size of the Galaxy and, most likely, will continue to grow and grow.
Based on these considerations, including speakers at home, the theoretical possibility of a black hole in the cavity of the subwoofer should always be allowed and remembered without turning on large speakers too loudly. Physics is a dark science, you never know what there might be in this box? However, if you approach the issue seriously, then all of the above must be borne in mind, when storytellers from CERN appear in another box and start broadcasting something there.
10 (to the power of 98) watt / meter2 is the energy required to saturate a cubic meter of air, which will collapse into a black hole the size of a Galaxy or even a Metagalaxy. But when it comes to particles accelerated to unimaginable speeds, energy is measured not in watts / meter2, but in smaller units. And the particle mass is also very small. Therefore, the transformation of an electron into a black hole is absolutely even real. It doesn't matter that at first the black hole will be small - it will gain size very quickly and no one at CERN knows where its edge will stop.
