How can we travel back in time?

The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. NASA’s space telescopes also give us a way to look back in time. Telescopes help us see stars and galaxies that are very far away.

How Is time travel possible?

Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.

Is it possible to travel back in time?

As far as we all know, traveling back in time is next to impossible. You can’t even send information back in time, because it can change things that have already happened, which is impossible. For example, you broke your leg while cycling. What if you could have traveled back in time and tell yourself to not go cycling on that day?

Where did time travel come from?

Mallett first encountered the concept of time travel back in the 1950s. “We hadn’t even gone into space,” he recalls. “And people weren’t even sure if we could.” Growing up in New York City’s Bronx neighborhood, and later in Pennsylvania, Mallett’s family struggled for money.

Is time travel possible in real life?

Joining the ranks of movie inventors like Doc Brown of “Back to the Future” are a few real-life scientists currently trying to realize the dream of turning back the clock to travel to the ultimate destination. Among them is Ron Mallett, an astrophysicist who has dedicated much of his adult life to the notion that time travel is possible.

When did Ron Mallett first discover time travel?

Ron Mallett and his family at Bronx Park in the 1950s. Mallett first encountered the concept of time travel back in the 1950s. “We hadn’t even gone into space,” he recalls.
