Can You Travel Back In Time?

Can we go back in time?

In all time travel theories allowed by real science, there is no way a traveler can go back in time to before the time machine was built. We could travel 10,000 years into the future and age only 1 year during that journey. However, such a trip would consume an extraordinary amount of energy.

Is it possible to travel to the past?

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, transversable wormholes, and Alcubierre drives.

Is it possible to go back in time and change the past?

It’s possible that you can go back in time, irrevocably change the past, but still exist in your original state despite the change. Of course, this doesn’t touch on many other time-travel challenges, but that’s conjecture for another time.

What if you could travel back in time?

If you travel close to the speed of light, you experience a phenomenon known as time dilation. Due to time dilation and length contraction, you might reach your destination in only a year, and then come back in just another year. But back on Earth, 82 years would have passed.

Can we travel to future?

We could travel 10,000 years into the future and age only 1 year during that journey. However, such a trip would consume an extraordinary amount of energy. Time travel to the past is more difficult.

Who built the first time machine?

For an Iranian scientist has invented The Aryayek Time-Traveling Machine. Or, at least, he says he has. According to today’s Telegraph, 27-year-old Ali Razeghi says that his much-needed creation can take you eight years into the future, so that you can see what you look like after that surgery you so covet every day.

Is it possible to build a time machine?

“While is it mathematically feasible, it is not yet possible to build a space-time machine because we need materials—which we call exotic matter—to bend space-time in these impossible ways, but they have yet to be discovered,” Mr Tippett said.

Can we travel at the speed of light?

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.

Is time a paradox?

A temporal paradox, time paradox, or time travel paradox is a paradox, an apparent contradiction, or logical contradiction associated with the idea of time and time travel. In physics, temporal paradoxes fall into two broad groups: consistency paradoxes exemplified by the grandfather paradox; and causal loops.

Can u go back in time?

In all time travel theories allowed by real science, there is no way a traveler can go back in time to before the time machine was built. We could travel 10,000 years into the future and age only 1 year during that journey. However, such a trip would consume an extraordinary amount of energy.

What are the rules of time travel?

Rules for Time Travelers

  • There are no paradoxes.
  • Traveling into the future is easy.
  • Traveling into the past is hard — but maybe not impossible.
  • Traveling through time is like traveling through space.
  • Things that travel together, age together.
  • Black holes are not time machines.
  • If something happened, it happened.
  • There is no meta-time.

What would you take back in time?

The first way is to build a battery after you go back in time. It wouldn’t be too hard.

Some Other Ideas.

  1. A time machine. This way you could go Back to the Future and get some other stuff.
  2. A computer (solar powered laptop).
  3. Smart phone.
  4. Scuba diving gear – or maybe a rebreather.

Why would you time travel?

Einstein’s theory of special relativity says that time slows down or speeds up depending on how fast you move relative to something else. Approaching the speed of light, a person inside a spaceship would age much slower than his twin at home. Also, under Einstein’s theory of general relativity, gravity can bend time.

Can we go in past or future?

As one scientist points out, we all constantly time travel — but it’s in only one direction. We’re inevitably moving 1 second at a time into the future, and we could go faster if we wanted. “Indeed, we can jump forward into the future as much as we want.

Can we travel a light year?

This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.

How fast will spaceships travel in the future?

The fastest outward-bound spacecraft yet sent, Voyager 1, has covered 1/600 of a light-year in 30 years and is currently moving at 1/18,000 the speed of light. At this rate, a journey to Proxima Centauri would take 80,000 years.Travel
