The scientific community frowned a lot at listening to the news: on the other hand, the topic is not exactly easy to accept.
Astrophysicist Ron Mallett, professor of physics at the University of Connecticut he recently told CNN to have written a scientific equation that could serve as the basis for the future construction of a real time machine.
The academician has even built a prototype device to illustrate a key component of his theory, but Mallett's fellow astrophysicists aren't convinced his time machine will ever materialize. On the other hand, it is also true that building time machines is not yet a consolidated habit in the scientific community.
Time machines have always populated the imagination of scientists, writers and enthusiasts. For centuries we have been wondering how to build a prototype, and from HGWells to John Titor's modern suggestions, the suggestion of having someone who knows how to create a time machine is always damned intriguing.
How does the time machine theorized by Ron Mallett work?
To understand Ronald Mallett's car, you need to know the basics of special relativity theory by Albert Einstein, according to which time accelerates or decelerates according to the speed with which an object moves.
Based on that theory, if a person were on a spaceship traveling at close to the speed of light, time would pass more slowly than it would be for anyone left on Earth.
In essence, the astronaut could whiz through space for less than a week and upon his return it would be 10 years for the people left on earth. A real journey into the future.
But while most physicists accept that jumping in time in that way is theoretically possible, traveling into the past is another matter entirely, and herein lies the crux of Ron Mallett's work. The astrophysicist has a laser-based solution in mind.
As the astrophysicist told CNN, his idea for building the time machine depends on another Einstein theory, the general theory of relativity.
According to this theory, massive objects bend space-time (an effect that we perceive as gravity). The stronger the gravity, the slower the time passes.
The astrophysicist built a prototype that shows how lasers could help achieve this goal.
"Studying the type of gravitational field produced by a ring laser", Mallett told CNN, "I intend to show how such a model can lead on a larger scale to a time machine based on this principle." A model that could be a paradigm of how a time machine is built.
As optimistic as Mallet may be about his work, however, his colleagues are skeptical that he is on the way to a functioning time machine with which to travel through historical eras.
“I don't think his work will be fruitful,” says the astrophysicist Paul Sutter. "I think there are profound flaws in his mathematics and in his theory, and for this reason a practical device seems unattainable".
Is there a time machine?
Mallet also admits that his idea is entirely theoretical at this stage. And even if his time machine worked, he says, it would have a serious limitation. A feature that would prevent anyone from going back in time for (I say any) thwart 11/XNUMX or change the course of past events.
"With this system it is possible to send information back to the past", he told CNN, "But only at the point where you turn on the machine."
