The TARDIS is the iconic time machine and spacecraft from the popular sci-fi series Doctor Who. The TARDIS functions by folding space using technology that taps into higher dimensions. But is there any scientific basis for this?

We have always wondered whether other intelligent life exists in this galaxy, but for the first time we have the technology to help answer that question. With artificial intelligence, researchers have renewed the hunt for alien life in space and also begun to wonder if an entirely new life form has been born on earth.
The Age of A.I. is a 8 part documentary series hosted by Robert Downey Jr. covering the ways Artificial Intelligence, Machine Learning and Neural Networks will change the world.

Billions of years in the future, The Time Traveler stands before a black ocean, under a bloated sun. The shore is scaled with lichen and flecked with snow. The crab things and giant insects that menaced him on his visit millions of years in its past are gone. Apart from the lapping of dark waves, everything is utterly still.
He thinks he sees something shifting in the waves nearby but dismisses it as an illusion; assuming it to be a rock. Still a churning weakness and fear deters him from leaving the saddle of the time machine. Perhaps this anxiety is just prompted by the ultimate desolation of this world.
Studying the unknown constellations, he feels a chill wind. The old sun is being eclipsed by the moon, or some other massive body – for it is possible that the Earth has shifted into a new orbit around its star.

One consequence of this is there is no guarantee the clocks will tick at the same rate. In fact, many clocks will tick at different rates.
Even worse, the faster you travel relative to someone else, the slower your clock will tick compared to theirs.
Spoiler alert: this article explains a key plot point, but we don’t give away anything you won’t see in trailers. Thanks to reader Florence, 7, for her questions.
At the beginning of the new Disney Pixar film, Lightyear, Buzz Lightyear gets stranded on a dangerous faraway planet with his commanding officer and crew.

After some serious number crunching, a UBC researcher has come up with a mathematical model for a viable time machine.
Ben Tippett, a mathematics and physics instructor at UBC’s Okanagan campus, recently published a study about the feasibility of time travel. Tippett, whose field of expertise is Einstein’s theory of general relativity, studies black holes and science fiction when he’s not teaching. Using math and physics, he has created a formula that describes a method for time travel.
“People think of time travel as something as fiction,” says Tippett. “And we tend to think it’s not possible because we don’t actually do it. But, mathematically, it is possible.”

Time travel into the past is a tricky thing. We know of no single law of physics that absolutely forbids it, and yet we can’t find a way to do it, and if we could do it, the possibility opens up all sorts of uncomfortable paradoxes (like what would happen if you killed your own grandfather).
But there could be a way to do it. We just need to find a wormhole first.

This is the official trailer/short film for the “Time Travel, Temporal Warfare & Our Future” webinar to be held on July 2, 2022. Covers the historical development of time travel technology in Germany and the United States, and how it has been used in a temporal war by different factions of humans and extraterrestrial organizations. Explains how humanity was manipulated through time travel technology, and how that is about to end as we enter a new period in human development due to the arrival of ET Seeder races.
Time travel makes regular appearances in popular culture, with innumerable time travel storylines in movies, television and literature. But it is a surprisingly old idea: one can argue that the Greek tragedy Oedipus Rex, written by Sophocles over 2,500 years ago, is the first time travel story.
But is time travel in fact possible? Given the popularity of the concept, this is a legitimate question. As a theoretical physicist, I find that there are several possible answers to this question, not all of which are contradictory.
The simplest answer is that time travel cannot be possible because if it was, we would already be doing it. One can argue that it is forbidden by the laws of physics, like the second law of thermodynamics or relativity. There are also technical challenges: it might be possible but would involve vast amounts of energy.
