is the time travel is possible on Earth
Answers
Answer:-
Time travel is actually already happening. Astronauts living on the International Space Station are moving faster than the people on Earth. This means that astronauts age slightly slower in space than they would back home.
One example of a time traveler was cosmonaut Gennady Padalka, who arrived back on Earth in September 2015 after breaking the record for the longest stay in space at 879 days.
"When Mr. Padalka came back from his adventures, he found the Earth to be 1/44th of a second to the future of where he expected it to be," wrote Princeton physicist J. Richard Gott in his book titled Time Travel in Einstein's Universe. "He literally traveled...into the future," Gott wrote.
Meanwhile, a real time machine has also already been built. It does not look anything like a DeLorean, but it is actually rather popular in the field of science, namely the Large Hadron Collider.
The Large Hadron Collider propels proton at nearly the speed of light, which is a speed that makes the relative time of the protons move around 6,900 times slower compared to human observers. In essence, the protons are being sent into the future.
