A new concept of time travel has scientists interested. Theoretical physicist Amos Ori at the Technion-Israel Institute of Technology in Haifa has been working on a groundbreaking new idea on the principles and mechanics of time travel.
Previous scientists looked to gravity to bend space and time but many dismissed it as impossible due to the need of an exotic form of matter with so-called “negative energy density.” Although this matter may exist, scientists concluded that it was in such small amounts that you could never get enough of it.
Ori’s research found that you do not need this matter to bend time and space and therefore he has eliminated a barrier of time travel.
It all starts with a donut-shaped hole enveloped within a sphere of normal matter.
