Sure, we haven't discovered any yet, but according to all the rules of theoretical physics, there's nothing forbidding it.
While every known particle in our Universe has positive energy and either positive or zero mass, it's eminently possible to have negative mass/energy particles in the framework of General Relativity. If we want to scale that up, however, to allow something like a human being through, that's going to take some work. mass/energy, while the other is built of negative mass/energy, the wormhole can become traversible. If one end of a wormhole is built out of positive. If the wormhole lasted for long enough, you could even potentially transport a particle through it, allowing it to instantly disappear from one location in spacetime and reappear in another.Įxact mathematical plot of a Lorentzian wormhole. If you connected these two curvature regions together, you could - for a brief instant - arrive at the notion of a quantum wormhole. A very strong, dense, positive energy fluctuation would create curved space in one particular fashion, while a strong, dense, negative energy fluctuation would curve space in exactly the opposite fashion. These include energy fluctuations in both the positive and negative directions, often very close by one another. In our known Universe, we have tiny, minuscule quantum fluctuations in the fabric of spacetime on the smallest of scales. The place to start is with the physical idea of a wormhole. Positive and negative energy fluctuations can create minuscule, quantum wormholes. large, varied, and important on the smallest of scales. But thanks to some very interesting properties of space and time in Einstein's General Relativity, traveling back in time may be possible after all.Īn illustration of the early Universe as consisting of quantum foam, where quantum fluctuations are. For a long time, there seemed to be no way to go back. Philosophically, there's also a famous paradox that seems to indicate the absurdity of such a possibility: if traveling backwards through time were possible, you'd be able to go back and kill your grandfather before your parents were ever conceived, rendering your own existence impossible. To most people, it's an idea that's relegated to the realm of fiction, as every law of physics indicates that motion forward through time is an absolute necessity. From the time turner in Harry Potter to Back To The Future to Groundhog Day, traveling back in time provides us with the possibility of righting wrongs in our own past. It's one of the greatest tropes in movies, literature, and television shows: the idea that we could travel back in time to alter the past. After decades of research, we may have hit upon a solution that's physically possible. The idea of traveling back in time has long fascinated humans, such as in Back To The Future's.
