Special theory of relativity – problems and solutions - Physics

Einstein’s theory of general relativity permits mathematical solutions where time loops back on itself. These structures, known as closed timelike curves, appear in models involving extreme gravity and spacetime rotation. While no experiment has proven time travel is achievable, physics has never fully forbidden it. Time travel remains mathematically allowed — even if technologically unreachable.
