Black holes are fascinating objects but there is a lot that we don’t know about them. With the advent of gravitational wave detection, we can finally start to understand these objects. But performing simulations to understand them better is extremely computational difficult, requiring supercomputers and sometimes months of calculations. This is because Einstein’s theory of general relativity is extremely precise but difficult to compute. Finding alternative methods is significantly worthwhile if it allows us to make approximations to better focus the more complex calculations.
Some physicists have found that they can use the mathematical framework of particle physics – Quantum Field Theory (QFT) – can be used to make some of these calculations. Importantly, they found that they can make similar predictions of the gravitation wave spectrum from blackhole collisions to the full general relativity version, and with significantly less computational burden.
In this video, I briefly describe some of the reasoning behind using this framework and future prospects.
