According to our current understanding of physics, bending spacetime alone does not provide a way to travel through time. While bending spacetime is a concept described by Einstein's theory of general relativity, it primarily explains the effect of gravity on the curvature of spacetime.
Time travel, on the other hand, involves the manipulation of time itself, allowing an observer to move backward or forward in time. This concept is still highly speculative and largely remains in the realm of science fiction. No scientific evidence or established theory supports the existence of practical time travel at this time.
Theoretical physicists have proposed various ideas and frameworks that explore the possibility of time travel, such as wormholes, closed timelike curves, and cosmic strings. However, these concepts often rely on exotic forms of matter or energy, which have not been observed or confirmed to exist.
While our understanding of physics may evolve in the future, at present, time travel remains a topic of scientific speculation and imagination rather than a practical and established scientific concept.
