The concept of using light waves to travel through time is largely speculative and based on fictional or theoretical ideas. While it is an interesting topic, it is important to note that our current understanding of physics does not support such time travel methods.
In established physics, the theory of relativity, as proposed by Albert Einstein, provides insights into the nature of time and its relationship with space. According to this theory, time dilation occurs as an object's velocity approaches the speed of light, but it does not allow for backward time travel or the ability to traverse time using light waves.
If, hypothetically, light waves could be used to travel through time, it would have profound implications. One potential consequence could be the violation of causality, where cause and effect become disconnected. This could lead to paradoxes and logical inconsistencies, making it challenging to imagine how events would unfold or how the universe would maintain consistency.
However, it is important to emphasize that time travel through light waves remains purely speculative. While scientists continue to explore the nature of time and investigate various theories, such as wormholes or the concept of closed timelike curves, there is currently no scientific evidence or widely accepted theory that supports the practicality or possibility of using light waves for time travel.
