He believes that if they are detected they would be evidence of extra dimensions in space, and give new insight into the formation of our universe. A black hole is an object so dense and with such a high gravitational pull that nothing can escape it, not even light. Any object or radiation that passes too close to the edge of the black hole, across an area called the event horizon, would be pulled inside.
The most well-known type of black hole is the astronomical kind, found in the centers of galaxies. These are thought to be formed by the gravitational collapse of giant stars. When the internal pressure of a star is not enough to offset its own gravity, it will collapse in on itself to reach very high densities, creating a black hole.
During the LHC's construction, much press was given to the theory that the accelerator would be responsible for the formation of rapidly expanding cosmic-type black holes. If this were to happen, the effects would be devastating, and spell the end of our solar system. You probably don't want to get into their valence quarks , unless you really understand quantum physics and don't mind your kids tuning you out.
As for why they're doing it, it boils down to the search for the Higgs boson , also called the "God Particle," which is the only elementary particle that has never been observed by science.
If your kids ask why that 's so important, point out that it was nuclear research that led to the creation of the Internet, and they may just finally understand why science is so important! Now, the other question is a bit tougher, because you I assume don't want to outright lie to your kids, but you don't want to alarm them, either.
It is actually possible, as I understand it, that the experiment will create subatomic black holes that will last a tiny fraction of a second before collapsing. But the likelihood of these black holes becoming the more well-known kind of black hole is nearly nonexistent.
That being said, if you've raised your kids in the proper GeekDad fashion, they'll have read a lot of science fiction by the time they hit high school. And sci-fi is, of course, full of stories about scientists with good intentions going too far and causing horrible consequences.
Although there are a number of particle accelerators around the world, each was built for a unique purpose. Scientists are hoping the LHC will be able to answer some of our most puzzling outstanding questions about the nature of the universe, including how stuff gets mass, what makes up dark matter, and why the universe is made up of matter and not anti-matter.
More than 8, scientists from almost 60 countries will collaborate on LHC experiments. The green light for the project was given 14 years ago, though some physicists have been planning the LHC since the s. The planet shields the accelerator from radiation that could interfere with the experiments. Not to mention buying that much land aboveground would have been really expensive! Hadrons are particles made up of bound quarks. A quark is a building block of larger particles such as protons and neutrons.
The LHC will manipulate two kinds of hadrons — either protons or lead ions — because a they are charged this allows them to be accelerated by the electromagnetic forces created in the machine and b they do not decay and are heavy so they will not lose too much energy as they are accelerated along the ring.
The God particle is the nickname given to the theoretical Higgs boson , a particle thought to explain why some things are more massive than others.
