Is TIME TRAVEL possible?

Time travel is generally discussed based on Einstein's theory of relativity. The theory suggests that time can be affected by factors such as speed and gravity. For example, when something approaches the speed of light, time is observed to slow down. At the same time, in a region under the influence of strong gravity, time also flows more slowly. Therefore, according to this theory, different time frames may exist at different speeds.

Some theoretical scenarios suggest that under certain conditions, time can be manipulated forwards or backwards. For example, orbiting around a black hole or undertaking a long journey might affect the flow of time.

However, so far, a practical way to apply these theories hasn't been found, and time travel remains a topic mainly in science fiction works and theoretical discussions.

Therefore, to truly understand if time travel is possible, more scientific research and technological advancements are needed.
