A new class of time machine
Presented without comment, except the comment that I know when I don’t know enough to comment:
“A physicist at the Israel Institute of Technology in Haifa has proposed a new class of time machines that seems to avoid some of the difficulties inherent in other theoretical time machines. Like many time machine models, the new proposal requires gravitational fields that curve spacetime in ways that allow observers to travel to their own past. However, unlike previous proposals that have typically required exotic and improbable forms of matter, the new time machine core would consist of a toroidal vacuum embedded in sphere of normal matter. Important questions remain, but at the very least the material required to make the machine exists in our universe.”
