A scientist, who became a physicist at the death of his father, suggested designing a time machine. In this respect informs Guard.
Professor Ronald Mallet lost his father in 1955 at the age of 9, the man died of a heart attack at a relatively young age. At the age of 10, the boy read HG Wells’ Time Machine, which tells about time travel, and he decided to become a physicist to invent a similar one, to go back to 1955 and save his father. Mallett’s scientific career was successful, he was able to defend his doctoral thesis and study black holes, and is now professor emeritus at the University of Connecticut.
Now Mallett understood the principle of time travel, as he put it, and found a way to apply it. To bend the space-time continuum, it is necessary to create a rotating circle of laser radiation. “It turns out that spinning black holes can create gravitational fields that cause time loops to appear and allow you to travel into the past. Unlike an ordinary black hole, a spinning black hole has two event horizons—one inside and one outside—a surface that limits the area where electromagnetic radiation cannot escape. Between these two event horizons, inertial frames of reference drift, a phenomenon predicted by Einstein’s Theory of Relativity.
Since humanity will never be able to artificially obtain a black hole in the foreseeable future, the physicist proposed replacing it with rotating laser radiation. “Light can create gravity…and if gravity can affect time, light itself can affect time,” Mallett explains. As an example, the scientist draws a square that “spins” in one direction with arrows next to it. As a result, a time loop must be created that allows time travel.
The present invention has three major drawbacks. Firstly, it is an abstract theoretical concept that has not been validated in practice. Second, according to critics, its implementation would require a laser ring the size of the visible universe and the energy of the stars of many galaxies, the author agrees. Additionally, travel back in time will be limited to the time the loop was created, meaning you can’t go back to 1955 anyway.
