Small black holes can have tubes inside the Earth’s rocks

Two thought-provoking cosmologists have good news for everyone: If a supermassive black hole passes through your body, you probably won’t die.

This unexpected confirmation is part of their larger hypothesis that scientists can find supermassive black holes (PBHs), the smallest, most fragile, hypothetical black holes. In a learning published in the December issue Physics of the Dark Universe and available online since September, astronomers suggest that evidence of PBHs may exist in empty celestial bodies, as well as material here on Earth.

“We have to think outside the box because what has been done to find black holes before has not worked,” said Dejan Stojkovic of the University at Buffalo, who co-authored the study, said at the university. words.

“Classical” black holes, if you can call them that, usually form after the death of stars that fall in. Black holes, on the other hand, may have formed shortly after the Big Bang, when dense matter collapsed back in, before stars existed – so original part.

Scientists have talked about the existence of PBHs for years, but have never seen them. According to this study, some experts say that PBHs may be the only dark matter (a mysterious substance that makes up 85% of the mass of the universe). “Person black holes (PBHs) are probably the most interesting and fascinating objects from the early universe,” the researchers wrote in the study.

Stojkovic and his colleagues calculated that if a high-velocity PBH with a mass of 2.2 x 10^19 pounds (which is 22 followed by 18 zeros) is shot through a solid object, it leaves behind a trench 0.1 micron thick. These are tiny, but still visible with powerful microscopes, meaning we can examine objects around us for evidence of their existence.

Ancient objects have a high probability of having a PBH tunnel, according to cosmologists. The “high chance” is still very low – they calculate the chance of a PBH shooting a billion-year-old rock to be 0.000001 percent – but not zero.

“The chances of finding the signatures are low, but searching for them will not require a lot of resources and the potential benefits, the first evidence of a black hole, could be huge,” Stojkovic said in a statement.

This also brings us to the possibility of PBH digging into your body, which is less than you can move a billion-year-old rock. Even if it does happen, the researchers are confident that you won’t be seriously injured, because human muscle has little stress, meaning PBH can go through without tearing.

“If the projectile is moving faster than the speed of sound, the cells of the medium don’t have time to react,” said Stojkovic. “Throw a stone at the window, it might break.” Shoot the window with a gun, maybe just leave a hole. ” PBH pressure can also inhibit the release of excess kinetic energy within your body.

Stojkovic and his colleague, De-Chang Dai of National Dong Hwa University and Case Western Reserve University, also suggest looking for evidence of PBH in celestial bodies with surprisingly low populations. It is believed that if a PBH hits a body such as a planet, moon, or asteroid with liquid water, it can be trapped inside and dislodge its core, removing it until the outside removes it.

“If the object has water in the core, then the trapped PBH can absorb liquid water, whose density is higher than the density of the outer metal,” Stojkovic explained. On the other hand, space without a liquid core can have small tunnels similar to those in solids on Earth.

As a result, the pair show that astronomers are finding galaxies with densities (which can be calculated from their motions) much lower than expected. They must also be smaller than one-tenth of the Earth’s length, because anything larger collapses in on itself.

Although these parameters are, in Stojkovic’s words, “out of the box,” the researchers emphasize that studies of such concepts are necessary. He said: “The most intelligent people in the world have been trying to solve these problems for 80 years and they still haven’t solved them.” “We don’t need to add directly to existing models. Maybe we need a completely new system.”

Although the average person does not participate in the new search for black holes, this is your signal to alert scientists if something unexpected has happened in your body.
