At present, there was no conclusive evidence to prove the existence of time travel. Although there were many science fiction novels and movies depicting the plot of traveling through time and space, scientists had yet to find any evidence that this ability really existed. However, humans 'understanding of time was obtained through observation and measurement of the passage of time. Time is a relative concept, it depends on the position and time of the observer. So we can control and change the flow of time to create seemingly impossible situations, but that doesn't mean that time itself doesn't exist or can be traversed. The existence of time travel was still a controversial topic in science. More research and evidence were needed to reach a definite conclusion.
