How close are we to finding out time travel is real?

Its got to be pretty close which means the apocalypse isnt far behind it.

How high you is

It is real. Google time dilation.

They were talking about using giant mirrors way out in space to see into the past.

To find threads that warrant this response makes me happy.

Wish I could travel back in time and save myself from opening this thread.

If we could travel backwards in time, wouldn’t it already be real?
Posted on 4/25/26 at 11:36 pm to crimsoncoded94
We already know it’s real

A small group of people know its real, but when the world starts to collapse they try to change the future by altering current events then if it doesnt work they go back in time and try over again.

Do they have to come through the time portal naked and alone without weapons?

I cant tell you that

Closed timelike curves are among the most controversial features of modern physics. As legitimate solutions to Einstein’s field equations, they allow for time travel, which instinctively seems paradoxical. However, in the quantum regime these paradoxes can be resolved, leaving closed timelike curves consistent with relativity. The study of these systems therefore provides valuable insight into nonlinearities and the emergence of causal structures in quantum mechanics—essential for any formulation of a quantum theory of gravity. Here we experimentally simulate the nonlinear behaviour of a qubit interacting unitarily with an older version of itself, addressing some of the fascinating effects that arise in systems traversing a closed timelike curve. These include perfect discrimination of non-orthogonal states and, most intriguingly, the ability to distinguish nominally equivalent ways of preparing pure quantum states. Finally, we examine the dependence of these effects on the initial qubit state, the form of the unitary interaction and the influence of decoherence.

If time travel is real it's always been real. It's not like we invent it tomorrow and everything falls apart.
If it's invented in the past, present, or future then we've always been dealing with it without knowing.

Time dilation lets us know that the past and present exist due to relativity.
