If you were given the chance to time travel on the condition that when you return to the present, you won’t be able to remember any of it — would you still take it? That’s not a trick question but a real consequence time travelers might face, suggests a new study. Until now, scientists have mostly focused on science and the possibility of time travel, but there is hardly any discussion on what happens to a person once they’re back in the present. Do they experience any changes? Study author Lorenzo Gavassino, who is a mathematician and postdoctoral student at Vanderbilt University in Nashville, claims that time travel does come with some peculiar side effects.
For instance, one major consequence of traveling in time might be that “Any memory that is collected along the closed timelike curve will be erased before the end of the loop,” Gassavino said . What it simply means is that as soon as a person is back in the present from the past, the memories of his journey will be wiped out — but why? The blame is on entropy A closed timelike curve (CTC) is a concept in general relativity where, under certain conditions, spacetime forms loops. These loops lead to the creation of paths in spacetime that return to their starting point, enabling the possibility of traveling back in time to an earlier point.
However, time travel is not beyond science, and therefore, a person’s journey along the CTC will also be governed by the laws of physics. For instance, when a person tr.
