Metaphor at the Edge of the Human

Posted by in categories: space, time travel

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.

In the New Disney Pixar Movie Lightyear, Time Gets Bendy. Is Time Travel Real, or Just Science Fiction?

Posted by in categories: space travel, time travel

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.

Is time travel real? What Pixar’s movie Lightyear shows about Einstein’s theory

Posted by in categories: entertainment, space travel, time travel

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.

Researcher uses math to investigate possibility of time travel

Posted by in categories: cosmology, education, mathematics, physics, time travel

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 . 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.”

Can wormholes act like time machines?

Posted by in categories: cosmology, physics, time travel

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.

Manipulating Humanity through Time Travel: How it Began and Ends

Posted by in categories: military, time travel

Dr. Michael Salla


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.

Can we time travel? A theoretical physicist provides some answers

Posted by in categories: energy, physics, time travel

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 in fact possible? Given the popularity of the concept, this is a legitimate question. As a , 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 , like the or relativity. There are also technical challenges: it might be possible but would involve vast amounts of energy.

Supernova reveals its secrets to team of astronomers

Posted by in categories: cosmology, time travel

An international group of astronomers led by Benjamin Thomas of The University of Texas at Austin has used observations from the Hobby-Eberly Telescope (HET) at the university’s McDonald Observatory to unlock a puzzling mystery about a stellar explosion discovered several years ago and evolving even now. The results, published in today’s issue of The Astrophysical Journal, will help astronomers better understand the process of how massive stars live and die.

When an is first detected, astronomers around the world begin to follow it with telescopes as the light it gives off changes rapidly over time. They see the light from a supernova get brighter, eventually peak, and then start to dim. By noting the times of these peaks and valleys in the light’s brightness, called a “,” as well as the characteristic wavelengths of light emitted at different times, they can deduce the physical characteristics of the system.

“I think what’s really cool about this kind of science is that we’re looking at the emission that’s coming from matter that’s been cast off from the progenitor system before it exploded as a supernova,” Thomas said. “And so this makes a sort of time machine.”

Stephen Hawking’s final book suggests time travel may one day be possible — here’s what to make of it

Posted by in categories: futurism, time travel

“If one made a research grant application to work on time travel it would be dismissed immediately,” writes the physicist Stephen Hawking in his posthumous book Brief Answers to the Big Questions. He was right. But he was also right that asking whether time travel is possible is a “very serious question” that can still be approached scientifically.

Arguing that our current understanding cannot rule it out, Hawking, it seems, was cautiously optimistic. So where does this leave us? We cannot build a machine today, but could we in the future?

Let’s start with our everyday experience. We take for granted the ability to call our friends and family wherever they are in the world to find out what they are up to right now. But this is something we can never actually know. The signals carrying their voices and images travel incomprehensibly fast, but it still takes a finite time for those signals to reach us.
