Some Known Details About Is Time Travel Possible? - Morgan Freeman - Metacritic

Time travel through a wormhole is technically possible under the guidelines of theoretical physicsthe just catch is that we can only ever go backward.In an article for Forbes, astrophysicist Ethan Siegel has actually discussed simply howwithin the realms of Einstein's General Relativitya person might take a trip through a wormhole and return in time.

The different changes would each produce a curved area that opposes the other. If these two were then linked, you would have a wormhole. If it lasted long enough, in theory a particle might be transferred through. Nevertheless, scaling this up so a human might go through would be more challenging.

Once we had this, then we would require to produce a supermassive black hole and negative mass/energy equivalent. This, he states, "ought to allow for a traversable wormhole."As soon as you have a wormhole, you then need the laws of special relativity to deal with the time element."If you take a trip near to the speed of light, you experience a phenomenon called time dilation," Siegel writes.

This is because time travels forwardbut how much depends upon how quick you are moving through area. With This Is Cool , this modifications." [Picture] one end of the wormhole stays near to motionless, such as remaining near Earth, while the other one goes off on a relativistic journey near to the speed of light.

What occurs?"Well, a year isn't the exact same for everybody, particularly if they're moving through time and space differently! If we speak about the exact same speeds as we did previously, the "in movement" end of the wormhole would have aged 40 years, but the "at rest" end would only have aged by one year.
