$\huge\sf\blue{Answer ✓}$

Unfortunately, nobody has ever managed to find one. This is where string theory comes in. It describes a string that looks exactly like a graviton: it spins in the right way, is massless and travels at the speed of light. For the first time, general relativity and quantum mechanics had found common ground.
