Scientists compare two approaches to the nature of time: timeless and with two directions — perhaps our reality is just their meeting point.

Usually time flows like a river, but in the quantum world physicists argue: can you turn it backwards? One approach says the world is frozen, everything has already happened. Another allows that particles live both forward and backward in time at once. Testing this idea might one day give us the key to controlling time.

🎯 If the two-time approach were correct, every particle in the Universe would have its 'twin,' living in the reverse time flow.

🎬 As in the movie 'Tenet,' where heroes move backwards through time, so this model suggests the existence of reverse motion for fundamental particles.
