A Nobel Prize-Winning Physicist Just Cracked Time Travel–Here’s How It’s Possibl

> By entering the wormhole here on Earth and traveling to the black hole, you can essentially wait for a billion Earth-years to pass, then pass through the wormhole again and emerge in the future.

> Alternatively, you can pass through the wormhole to the black hole and emerge in the “past.”

This is not time travel any more than I'm travelling into the future right now at the rate of 1s/s. For it to be time travel I'd have to come out the other end before I entered, not just traveling into the future faster/slower than the other end while passing time I don't get back whatever the ratio.

It's possible until the end of the article, where they explain that it's not possible.

Travel just one day into the past and you will die in the vacuum of space.
