@Musicman ""Einstein's theory describes the world at the very large scale of stars and galaxies, while quantum mechanics is an excellent description of the world at the very small scale of atoms and molecules."
Simulating time travel
The scientists simulated the behaviour of two photons interacting with each other in two different cases.
In the first case, one photon passed through a wormhole and then interacted with its older self.
In the second case, when a photon travels through normal space-time and interacts with another photon trapped inside a closed timeline curve forever.
"The properties of quantum particles are 'fuzzy' or uncertain to start with, so this gives them enough wiggle room to avoid inconsistent time travel situations," said co-author Professor Timothy Ralph.
"Our study provides insights into where and how nature might behave differently from what our theories predict."
Although it has been possible to simulate time travel with tiny quantum particles, the same might not be possible for larger particles or atoms, which are groups of particles."
