Time Travel is Real (And Astronauts Are Already Doing It). What if I told you that time travel is not science fiction? It's a fact of physics, and astronauts like Scott Kelly have already done it, returning to Earth fractions of a second younger than the rest of us. They are real-life time travelers. In this episode, we're unlocking the secrets of Albert Einstein's theory of special relativity to explain how traveling to the future is not just possible, but inevitable for anything moving at high speed. We'll explore the mind-bending reality of time dilation. But what about the holy grail: backward time travel? We'll journey to the theoretical edge of science, exploring bizarre concepts like wormholes that require hypothetical "negative mass" to function. And we'll confront the ultimate cosmic rulebook: the "self-consistency principle," the universe's built-in defense system against the grandfather paradox. Stick with us to the very end to learn about the bizarre concept of a closed timelike curve—a scenario where the past and present are locked in an unbreakable, unchangeable loop. The future is stranger than you think. Subscribe, share this with your favorite sci-fi fan, and tell us: If you could travel to any one moment, where would you go?

The fact that certain people are alive is absolute proof that no one in our timeline ever invents time travel.

WRITER FUEL: The grandfather paradox is just one of the thorny logical problems that arise with the concept of time travel. But one physicist says he has resolved them.

There is a blue swirl in the center of the image; it looks somewhat like a spiral galaxy. In the center, the title is "Grandfather Paradox". Around the swirl is a sequence of phrases. Starting from the top left and following the arrows going around clockwise, the statements are: I'm born. Create time machine. Go into past. Kill grandfather. Father not born. I'm not born. I don't create time machine. I can't go into the past. Grandfather alive. Father born. ...at which point, the circle starts again with "I'm born."

A kind of southern swamp 'Predestination'. Lots of timey wimey family stuff. Interesting Grandfather Paradox story but mediocre directing and storytelling leaves the plot developments confusing and unnecessarily vague.

At the Paris Paradox Museum, there was a Möbius strip with the #GrandfatherParadox, a classic #TimeTravel conundrum. Not easy to film, I tried my best.
