  • Earth is in danger.

  • Scientists are a step away from creating a black hole, a scientific experiment that could lead to the apocalypse.

  • Articles with similar headlines began surfacing in the press in the early 2000s.

  • The Large Hadron Collider, or simply LHC, started up in 2008.

  • It caused a real storm of discussion.

  • While some scientists planned grandiose experiments, others warned mankind of serious danger.

  • How does the LHC work, and is it really capable of destroying our planet?

  • The Large Hadron Collider is installed underground near the French-Swiss border.

  • It's a ring-shaped tunnel with a circumference of 27 kilometers, or 16.7 miles.

  • Two vacuum pipes are installed inside the tunnel, which intersect in some places.

  • 1,232 main magnets are connected to the pipes.

  • Their task is to accelerate protons to a speed close to the speed of light, and then hold this stream so that the particle beams don't crash into the wall.

  • In order for the magnets to work, they're powered by superconductive cables with a total length of about 250,000 kilometers, or about 155,000 miles.

  • If scientists got tired of the LHC, and they decided to dismantle it, these wires could be wrapped around the Earth about six times at the equator.

  • And even after that, there'd be enough wire left to run a power grid somewhere in Antarctica.

  • Although, why a power grid in Antarctica?

  • While they aren't planning to disassemble the LHC yet, however, it could be considered the largest refrigerator ever created.

  • For proper operation, the collider magnets need to be cooled to minus 271.3 Celsius, that's minus 456.3 Fahrenheit.

  • That is, to create a temperature lower than in space.

  • To get this cold, 120 tons of liquid helium is poured into the LHC.

  • Now, look at the refrigerator in your home.

  • In it, there are special substances, refrigerants, that create cold.

  • Liquid helium is one of them.

  • In one household refrigerator, there are approximately 30 to 50 grams, or 1.05 to 1.76 ounces of refrigerants.

  • So we can say that the LHC surpasses this indicator by approximately 4 million refrigerators.

  • Only instead of cooling products, it helps solve the most complex problems of modern physics.

  • For example, what does matter consist of?

  • From school we know that matter consists of molecules, molecules of atoms, and atoms of protons, electrons, and neutrons.

  • But modern science has gone even further.

  • It turns out that even the smallest particles of the atomic nucleus, for example, protons, consist of even smaller particles, quarks.

  • Want to know how small they are?

  • Then imagine that an atom has grown to the size of the Earth.

  • Then a proton would have a radius of about 100 meters, or 328 feet.

  • That's almost the length of a football field.

  • In this case, the quark would have a radius of about 5 centimeters, or 2 inches.

  • That is, it could fit in your pocket.

  • But how can we examine such small particles?

  • This is why the LHC was created.

  • You take two beams of protons, accelerate them in opposite directions, and collide them with each other.

  • What would happen if you put a brick on the ground and threw another one on top of it?

  • Most likely, small fragments would fly off in different directions.

  • Similarly, when protons collide, tiny particles can break away from them.

  • In ordinary language, a collider is needed in order to see what happens when the protons and heavy lead nuclei collide.

  • As the creators of the project admitted, pushing two protons together is about as difficult as getting a needle into a needle, provided that the distance between them is 10 kilometers, or 6.2 miles.

  • And at the same time, they need to collide exactly in the middle.

  • Not so easy.

  • In addition, these small particles are invisible, so physicists can only study them by examining the tracks they leave in their wake.

  • Another task of the LHC is to find something new.

  • It was with its help that the Higgs boson was discovered.

  • This invisible particle can be called the foundation of the universe.

  • After all, it's this particle that gives the other ones, and therefore all matter, mass.

  • It turns out that if it disappeared, all particles would become absolutely weightless and fly around the universe at the speed of light.

  • In addition, with the help of the LHC, it's possible to study other elementary particles.

  • Each of them helps in the emergence and interaction between atoms.

  • And each of these particles is so small that they can be detected only when proton fluxes collide.

  • Scientists register the particles that are then formed with the help of special detectors.

  • Another interesting area of research is antimatter.

  • In our world, atomic nuclei have a positive electric charge.

  • Negatively charged electrons revolve around them.

  • But for each particle of an atom, you can create a double, an antiparticle.

  • It has the same mass and properties, but the opposite charge.

  • For example, an electron is negatively charged, and its antiparticle, positron, has the same mass but is positively charged.

  • The same goes for protons.

  • Protons are located in the nucleus of an atom and have a positive electric charge.

  • But their antiparticles, antiprotons, carry a negative charge and at the same time have the same mass.

  • We can say that antiparticles are a mirror image of ordinary particles.

  • If you approach a mirror, you'll see your reflection in it.

  • If you wave to it with your left hand, your mirrored double will answer you with a wave of its right.

  • Antimatter is similarly arranged.

  • With the help of the LHC, it's possible to not only create antiparticles, they can also be combined with each other to create whole atoms of antimatter.

  • Under ordinary conditions, when one proton and one electron are joined, a hydrogen atom appears.

  • Now, we can take two antiparticles opposite to the proton and electron, the antiproton and positron.

  • Connecting them, we get an antihydrogen atom.

  • It will have the same properties as hydrogen itself.

  • But only when antihydrogen collides with an ordinary atom would an explosion occur.

  • A strong explosion, as a result of which an incredible amount of energy would be released.

  • One kilogram or 2.2 pounds of antihydrogen can produce slightly less energy than was released during the Tsar Bomba explosion.

  • And that was the most powerful of all hydrogen bombs ever created by mankind.

  • Most physicists believe the LHC is pretty cool.

  • There's only one small problem.

  • Scientists believe that one of its future experiments could destroy our planet.

  • Or at least it could create serious problems.

  • In 2008, opponents of the collider, Walter Wagner and Louis Sancho, even went to court.

  • They demanded a prohibition on starting up the LHC.

  • The applicants feared that if protons collided so strongly, they could form a microscopic black hole.

  • The gravity of this object would be so great that it would immediately begin attracting the surrounding molecules.

  • Or it might completely drag the entire Earth into it.

  • But don't worry.

  • None of the past experiments have confirmed the possibility of creating black holes.

  • Even if such objects appeared inside the tunnel, their size would be so small that they would evaporate instantly.

  • So the lawsuit to ban the LHC was rejected by the court.

  • The LHC started up, and so far it's been working successfully.

  • There's another potential threat.

  • Scientists believe that in some places of the universe there are wormholes.

  • These are hypothetical objects in which space-time is curved.

  • We can say that these are tunnels connecting two remote areas of space-time.

  • And if you enter one of these tunnels, you could either travel in time or instantly move somewhere very far away.

  • Even to another universe.

  • Some scientists fear that high energies may create such a wormhole inside the LHC itself.

  • However, this is just a theory.

  • The creators of the LHC claim that such particle collisions occur on our planet even without human intervention.

  • It's believed that for billions of years, various cosmic particles with an energy millions of times greater than the energy of protons in an accelerator have been bombarding the

  • Earth.

  • And this hasn't led to the appearance of black holes on the planet, or other terrible consequences.

  • It's unlikely that such an experiment inside the LHC would transport us to another dimension.

  • But moreover, I'm carefully monitoring everything that happens with it.

  • So if anything ever goes wrong, you'll be the first to know about it.

  • Don't forget to subscribe to the channel to follow along with me on future experiments.

  • And be sure to like this video and share it with your friends if you haven't done so already.

Earth is in danger.
