Learn all about Quantum Gravity in a minute ⚡the holy grail of physics #physics #quantumgravity
Quantum gravity is the holy grail of physics. It's the attempt to unify two of the most successful theories ever: quantum mechanics and general relativity. Quantum mechanics describes the weird and wonderful world of atoms and subatomic particles, where things can be in two places at once, or pop in and out of existence. General relativity describes the majestic and mysterious world of gravity and spacetime, where mass bends space and time, and black holes lurk in the shadows. But these two theories don't play well together. When we try to combine them, we get nonsensical answers, like infinite energies and probabilities greater than one. That's why we need quantum gravity: a theory that can explain how gravity works at the smallest scales, where quantum effects dominate. But finding such a theory is easier said than done. There are many candidates, such as string theory, loop quantum gravity, causal dynamical triangulation, and more. But none of them have been tested experimentally yet, and some of them may never be. Quantum gravity is one of the biggest mysteries of modern science, and one of the most fascinating topics you can learn about in a minute.
