Actor and writer Natasha Rothwell takes the stage for “On the Spot,” TED’s rapid-fire Q&A format. Answering a stream of unexpected questions, she dishes on everything from creativity and representation in TV to love, the first “pinch me”...

Don't second-guess what "distracts" you, says actor-producer Yara Shahidi; that's your curiosity coming through. The star of hit shows like "black-ish" and "grown-ish" tells how she learned to spot clues to her own future — and how you...

Time travel stories are cool because both the past and future are somehow more interesting that the present and because everyone wants a redo. But so far it appears we’re doomed to live consumed by regret in the eternal, boring present....

Causality is meant to move in one direction: forward. But the Quantum Eraser experiment seems to reverse causality. How and why can this happen and what are the implications of this experiment on how we understand Quantum Mechanics and...

This is a map of the multiverse. Or in physics-ese, it’s the maximally extended Penrose diagram of a Kerr spacetime. And in english: when you solve Einstein’s equations of general relativity for a rotating black hole, the universe does...

You and the professor have driven your DeLorean back to the past to fix issues with the spacetime continuum caused by your time traveling. But another DeLorean appears with older versions of you and the professor. The professors panic...

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

Hank tells us about the Mayan calendar & why December 21, 2012 will not be the end of the world.

Squeaks is feeling nostalgic today, so he and Jessi are revisiting times in the past that he had tons of fun with all his friends at The Fort!

By choosing the right path and the right reference frames, any superluminal motion can lead to information or objects returning to their origin before they depart.

If you could travel back in time, and you killed your grandfather, would you be killing your future self? What do physics, complexity theory, and computer science have to say about this famous murderous time-travel paradox?

You've discovered a habitable exoplanet, but so has an an evil interplanetary mining corporation. Can you get to the planet before they strip it bare and leave it unsuitable for life? You're going to need a ship, the Lorentz...

For ages I’ve been thinking about doing a video analyzing time travel in fiction and doing a comparison of different fictional time travels – some do use wormholes, some relativistic/faster than light travel with time dilation, some...

Hank tells us about the Mayan calendar & why December 21, 2012 will not be the end of the world.

Time travel is a staple of science fiction stories, but is it actually possible? It turns out nature does allow a way of bending time, an exciting possibility suggested by Albert Einstein when he discovered special relativity over one...

Three Simple Ways to Time Travel

Is the Time Stone in the Eye of Agamotto from Marvel's Dr. Strange based on real science? Yes! The Time Stone is in fact an example of an object that physicists have recently dreamed up and actually made, called a...

Traveling forward in time is not a problem. You're doing that now. Can we travel backward in time? There is a theoretically possible way to do it using wormholes.



One solution to general relativity...

Time travel is nothing special. You’re time traveling right now into the future. Relativity theory shows higher gravity and higher speed can slow time down enough to allow you to potentially travel far into the...

Is time travel possible? Of course it is…into the future. You and I are travelling in time right now. And travelling into the far future also is also a reality using Einstein’s principle of time...
