A renowned astrophysicist has claimed that traveling back in time could be theoretically possible, thanks to the potential presence of numerous wormholes across the universe. Astrophysicist Ethan Siegel exhorts that based on the rules of theoretical physics, certain conditions may lead to the development of elaborate wormholes that may allow people to revisit the distant past.

The expert added that the key to time travel is harnessing negative mass/energy particles. According to Siegel, these elusive negative particles are the exact opposite of known positive energy/positive or zero mass particles that are found throughout the universe. The scientific community has long believed that negative mass/energy particles are existent, but are yet to be discovered, Siegel added.

“If this negative mass/energy matter exists, then creating both a supermassive black hole and the negative mass/energy counterpart to it, while then connecting them, should allow for a traversable wormhole. No matter how far apart you took these to connected objects from one another, if they had enough mass/energy – of both the positive and the negative kind – this instantaneous connection would remain,” Siegel told Daily Mail online.

According to Siegel, harnessing these negative particles may help build a wormhole that is designed to allow one end to move at the speed of light, while the other remains almost motionless. The expert infers that jumping through the elaborately constructed wormhole may then allow a person to travel in the past.

“If, 40 years ago, someone had created such a pair of entangled wormholes and sent them off on this journey, it would be possible to step into one of them today… and wind up back in time at the mouth of the other one… back in 1978. The only issue is that you yourself couldn’t also have been at that location back in 1978; you needed to be with the other end of the wormhole, or traveling through space to try and catch up with it,” Siegel added.

Time travel remains to be a hot topic over the years

Time travel has been a source of speculations and intrigue for ages largely due in part to various reports claiming the possibility of such an event. A man named Noah has claimed that he was able to go back in time from 2028. In a video posted by the YouTube channel Paranormal Elite, Noah reported that he came back in order to warn people that time travel technology does exist. Noah has also cited that he is 50 years old, and that he has taken secret drugs to bring back his youthful body.

In November 2000, a man named John Titor stirred up online discussions as he claimed to have traveled from the year 2036. According to Titor’s accounts, he used a time machine that is a stationary mass, temporal displacement unit manufactured by General Electric. Titor has also claimed that he is a member of a special military unit that retrieves items from the past in order to help the society recover from a limited nuclear war between Russia and the U.S.

“The people that survived grew closer together. Life is centered on the family and then the community. There is no large industrial complex creating masses of useless food and recreational items. Food and livestock is grown and sold locally,” Titor stated in a Daily Telegraph report.
