Use of black holes as particle accelerator

After the discovery of the Higgs boss of the great Hadron collider, there was much discussion about where to go from here. LHC is currently the strongest particle accelerator in the world that runs particles in the energy of about 13 TeV. Although it brought this some tips on physics outside the standard model, probably will not solve some of the biggest issues in particle physics. We need a much stronger particle accelerator. There is a proposal to build a Future Circular Collider, which would be nearly ten times the LHC, but construction and management would be extremely expensive and some scientists you wonder if it would be worth the cost.

What if we could use a particle accelerator that already exists in nature? What if you used black holes? We already know that black holes are powerful motors that generate jets of high energy particles that run away from the black hole at almost the speed of light. Unfortunately, all exotic particles with high energy would rapidly decay, so they could not be directly observed. But a Recent article in Physical Review D claims that they could be viewed indirectly through gravitational waves.

In the last few years, astronomers have observed gravitational waves arising from the association of black holes and neutron stars. They can be observed with sufficient sensitivity to determine things such as the initial masses and rotations of the joining bodies, as well as the mass and rotation of the resulting black hole. But with greater sensitivity, you should be able to measure other energy fluctuations that occur in the merger, and that is where this new article comes from.

Turning black holes usually give energy to every cloud that surrounds them through a process called frame drawing. If the scattered cloud of matter was around a black hole, when it began to combine with another, the effect of dragging the frame between two black holes could carry huge amounts of energy on matter. Similarly, the way the satellite can be pushed past Jupiter to reach the external solar system, but much stronger. Known as a super-shine, we would create a particle beam that is much stronger than anything we can create on Earth. And this could create exotic particles beyond the standard model. These particles could not be observed directly, but the particle energy would affect the gravitational waves generated by the black holes. If we are looking for fluctuations in gravitational waves, we can learn that exotic particles exist or at least define the boundaries on which exotic particles do not exist.

The particle accelerator with a black hole would not be as accurate as the one on Earth. But perhaps by studying the gravitational waves, we can realize that there are particles that go beyond the standard model, and that the construction of new particulate accelerators can be worth the effort.
