Is a time machine technologically possible? (with photos)

According to Albert Einstein’s Theory of Relativity, an astronaut traveling at close to the speed of light would experience time much more slowly than a person standing still.

In short, it is possible to build a time machine, but just because building something is possible, however, does not make it easy or likely. Albert Einstein’s Theory of Relativity states that time and space cannot be separated, but depend on each other. Therefore, a time traveler must move through time and space. For example, if a traveler went back in time six months, but didn’t travel in space, he might exit the time machine into outer space, because Earth would be on the other side of the sun. Space-time is the entity through which a time machine must travel.

Time travel is possible. The faster an object moves, the slower it ages compared to a stationary object. If the time machine moves close to the speed of light in outer space, it will return to Earth many years into the future.

The crew of a manned spacecraft technically moves slightly ahead of Earth’s inhabitants in time as they orbit the planet due to the high speeds they experience, but the time lapse can only be detected by accurate atomic clocks.

When people look at the stars, they are seeing the past, because it took light years for light to reach Earth. In theory, the person in the time machine would travel through time, but not age. Humanity has yet to build an engine that will propel a rocket that can transport a human at the speed of light or a rocket that will withstand the pressure and heat that would result.

Tesseracts visually represent the four dimensions, including time and space, that a time traveler would need to traverse.

Science fiction aficionados are familiar with wormholes as a means not only of time travel, but also of filling in the gaps between two distant places. In the Star Trek: Deep Space 9 television series, spaceships travel through wormholes to reach distant corners of other universes. Wormholes can be better understood when we visualize a piece of paper with a hole at one end. The distance between the holes is reduced by folding the paper and placing the holes on top of each other. The small space between the two holes is the wormhole.

The characters of “Dr. Who” use a time travel machine called the TARDIS.

Black holes in space have a greater gravitational pull. Objects in space such as comets, asteroids and even entire solar systems are being sucked into black holes. The black hole’s gravitational pull eventually deflects light and changes – slows down – the speed at which light travels. If Einstein is correct in saying that nothing can travel faster than the speed of light, then time itself has slowed down near the black hole’s mouth.

If a man were to fly a rocket or spacecraft near the mouth of the black hole, he would find himself in a time machine, because the time he is traveling through moves slower than the time in the rest of the universe. As he moves his ship away from the black hole, time would have moved faster away from the black hole, and he would likely be in the future.
