Science says time travel is possible

“My model of a time machine uses the curved space-time — to bend time into a circle for the passengers, not in a straight line,” said Tippet. “That circle takes us back in time.”

Thanks to Einstein’s theory of general relativity, we already know that spacetime is curved. (If it wasn’t, all the planets and stars would exist in a straight line.) The 102-year-old theory states that the massive gravity of large objects forces spacetime to bend around them. It’s the same theory that predicted gravitational waves, which were detected in February 2016.

“Experts in my field have been exploring the possibility of mathematical time machines since 1949,” said Tippet. “And my research presents a new method for doing it.”

It's a fascinating field of research, but it will probably always remain theoretical.

Not unless you have a Delorean, Flux capacitor and Mr Fusion
Superluminal communication. ... Faster-than-light communication is, by Einstein's theory of relativity, equivalent to time travel. According to Einstein's theory of special relativity, what we measure as the speed of light in a vacuum (or near vacuum) is actually the fundamental physical constant c.
 
My thought is, as previously mentioned, time travel does not mean time-space travel.

The meaning of time could be inferior than the meaning of time-space.

Or time does not exist, while time-space does exist. Without space, merely time could not be useful/meaningful enough.

Because of time-space, people cannot change our history due to time travel possibility/reality, nor time-space travel.

Just 2 cents.
