Special relativity was proved correct.
Most sci-fi film directors applied this principle in their films to
show the impossible which can be made possible by physics,
maybe not now, but in near future. And, through the grandfather
paradox, a much bizarre phenomenon was proposed, time travel.
Time travel and the future
In the movie Justice League of 2017 Superman died, one of
many heroes of DC Studios. Flash was also another hero, who
had the ability to relativistically accelerate, approaching speed
of light such that time within his vicinity would slow down and
move back into the past. This ability enabled Flash to traverse in
time, into the past, to an instant during which Superman was
alive. That’s how the hero was brought back to life.
During the year 2009, Stephen Hawking held a party of which
he didn’t invite anyone to attend it. He believed that, if time
travel was possible, he was going to have visitors from the
future who already knew about the party before he even held it.
Unfortunately, no one attended the party. This left Hawking
dubious as he asked, “If time travel is possible, where are the
visitors from the future?”
