Dr. Who’s box that travels through time and space might be possible to build, with the right materials
Physicists have devised a plan to build a time machine that is mathematically consistent with known physics. And this is the best part: they have called the machine a “Traversable Acausal Retrograde Domain in space-time”. Whose acronym is actually TARDIS.
For those who are not fans of the science fiction television program ` ` Doctor Who , ‘ ‘ TARDIS is the fictional spacecraft that travels in Doctor’s time. (Although in the program, TARDIS means “Time and relative dimensions in space”).
The real life machine imagined by physicists; It is like the fictional box-shaped TARDIS, which is capable of carrying passengers back and forth through time and space. All it takes to build it is the materials.
“Humans think of time travel as something like fiction. And we tend to think that it is not possible because we really do not, ”Ben Tippett of the University of British Columbia, the intellectual author of the invention, told Phys.org . “But mathematically, it is possible.”
Tippett and his colleague David Tsang of the University of Maryland. They have used Einstein’s theory of general relativity to arrive at his mathematical model for time travel. They claim that the division of space into three dimensions, over time into a separate dimension in itself, is incorrect. Instead, his model conceptualizes space-time as a continuum, in which different directions connect within the universe’s curved structure.
Tippet also reminds us that time is curved in the same way as space. ”The time-direction of the space-time surface also shows curvature. There is evidence that shows that the closer a black hole is, time moves slower. The time machine uses curved spacetime to fold time in a circle for passengers; Not in a straight line. That circle takes us back in time. ”
It is very exciting to think about this; But another thing is to imagine a machine that can transport passengers in a feasible (and safe) way through time. If the box-shaped device provided by Tippett and Tsang were really going to work. It would have to be built with extremely exotic materials … and that is the problem. These materials are so exotic that they have not yet been discovered.
So, although building a TARDIS is mathematically possible. The materials with the necessary properties to open a hole through space-time and also resist a jump through it are merely theoretical. That does not mean that such materials cannot be produced one day.
Of course, there are also several paradoxes of time travel that we would have to deal with. Like the grandfather’s paradox (if you could travel back in time and kill your grandfather, would you have been born in the first place?) So maybe time travel is not something we really want to mess with, even if it’s possible .
On the other hand, could you resist the temptation if a TARDIS suddenly appeared in your neighborhood?
