Time Travel Is Possible Through Wormholes—but You Can Only Ever Go Backward
Time travel through a wormhole is technically feasible under the rules of theoretical physics—the only catch is that we can only ever go backward. In a blog post for Forbes, astrophysicist Ethan Siegel has explained just how—within the realms of Einstein’s General Relativity—a person could travel

But then going back past the beginning, may propel into the future in theory,if indeed time-space is curved
Basic physics says, for every action, there is an opposite reaction. Surely that means there must be a way of going forward too?
My dream of being a real-life Biff Tannen remains intact!
What if you go through the back side of the wormhole? 🤔
Probably because technically you can go forwards by approaching a large enough gravity well as time slows dramatically as you approach the event horizon.
That is what portals are for to go forward.
More than anything I want to travel to the 1970s or 1980s!
Looks good on paper.
Since we have never been visited by a visitor from the future, the clear implication is that time travel will never be possible.
