Affiliate Professor of Physics at Brock College, Canada, Barak Shoshani, spoke on the subject of time journey.
Theoretically, in accordance with the scientist, this can be attainable, however this requires applied sciences which can be at present underdeveloped. And in addition it’s obligatory to unravel numerous issues with time paradoxes.
“first, the time machine wants unique matter, that’s, matter with damaging power. In concept, such matter will be created, however in very small portions. However even right here there isn’t a proof that it’s inconceivable to acquire a ample quantity of this matter or do with out it in any respect, ” Shoshani defined.
The second downside with time journey has to do with paradoxes. Probably the most well-known is the paradox of consistency, when a sure occasion happens that adjustments the previous, however the change itself, in flip, prevents the occasion.
Nevertheless, paradoxes can’t be created, since that is solely a theoretical idea that signifies the failure of the idea, and never an occasion that may truly occur.
One try to eradicate paradoxes is the precept of self-consistency, proposed by cosmologist Igor Novikov, who claims that journey into the previous is feasible, however it can’t be modified.
Nevertheless, Shoshani demonstrated that there are paradoxes which can be unresolvable from the standpoint of the Novikov precept, however they are often resolved if we permit the existence of many parallel timelines. The time traveler enters the previous, however in a distinct timeline, the place he can do no matter he needs, whereas the occasions within the unique timeline stay unchanged.
At present, Barak Shoshani teaches physics and astronomy, and, working with a staff of scholars, is making an attempt to construct a concept of time journey that will match into the information identified to trendy physics.
