Although Einstein’s theory seems to make time travel difficult, some researchers have proposed other solutions that may allow time to jump. These alternative theories have an important flaw: As far as scientists know, it is impossible for a person to survive the gravitational and pulling forces required for every solution.
The Theory of Infinite Cylinders
Astronomer Frank Tipler proposed a mechanism (sometimes called Tipler’s Cylinder) that can draw matter 10 times the mass of the sun into a very long but dense cylinder. The Anderson Institute, a time travel research organization, described the cylinder as “a black hole passing through a spaghetti factory.”
According to the Anderson Institute, after rotating the black hole pasta billions of revolutions per minute, nearby spacecraft can follow a very precise spiral around the cylinder and return to it in a “closed, time-like curve.” past. The main problem with
is that for the Tipler cylinder to become a reality, the cylinder must be infinitely long or made of some unknown substance. At least for the foreseeable future, endless interstellar pasta is out of reach.
Time Donuts
Amos Ori, a theoretical physicist at the Technion-Israel Institute of Technology in Haifa, Israel, proposed a time machine model made of curved space-time: a doughnut-shaped void surrounded by a sphere of normal matter.
“The machine itself is time and space,” Ori told Live Science. “If we were to create a distorted area like this in space and let the timeline close by itself, it could bring future generations back to our time.”
has some warnings about Ori’s time machine. First of all, the past visitors cannot travel to the era before the invention and construction of the time donut. Second, and most importantly, the invention and construction of this machine will depend on our ability to manipulate the gravitational field at will; This feat may be theoretically possible, but it is certainly beyond our direct ability.

Time travel has long held an important place in novels. Lisa Yaszek, a science fiction studies professor at the Georgia Institute of Technology in Atlanta, told Live Science that in the ancient Sanskrit epic “Mahabharata” compiled around 400 BC. C., humans dream of warping time.
Each travel novel has created its own time-space version, bypassing one or more obstacles and scientific paradoxes to meet the plot requirements.
Some people agree with research and physics, such as the 2014 film Interstellar directed by Christopher Nolan. In the film, a character played by Matthew McConaughey spends several hours on a planet orbiting a supermassive black hole, but due to time dilation, observers on Earth see these times as decades.
Others take a more whimsical approach, such as the TV series “Doctor Who”. The protagonist of the series is an alien “time lord” doctor, who travels in a spaceship similar to a British police blue box. “People think,” explained the doctor on the show, “time is a rigorous process from cause and effect to result, but in fact, from a non-linear and non-subjective perspective, it is more like a big ball than shake time. it’s long. ”
Long-standing franchises, such as the “Star Trek” movies and television series, and comic worlds such as DC and Marvel Comics, take up the idea of ​​time travel again and again.
