How scientists are creating real-life invisibility cloaks - Max G. Levy

--

A spy presses a button on their suit and blinks out of sight. A wizard wraps himself in a cloak and disappears. A star pilot flicks a switch, and their ship vanishes into space. Invisibility is one of the most tantalizing powers in fiction, spanning all kinds of stories. But could this fantasy ever become a reality? Max G. Levy digs into the technologies that could make invisibility possible.

An interesting point: If you became invisible in the sense that all light perfectly bends around you such that observers only see what’s around and behind you, you yourself would be unable to see, because the light is bending around you and not reaching your eyes to give you information.

When they finally invent invisibility cloaks, introverts are going to treat them like pajamas

[Discerned_]

Be sure to make a distinction between invisibility cloaks and invisibility clothes.
You might end up on a list or as foolish emperor who got swindled.

When I was a teenager, I was big into professional wrestling. I got a full back tattoo of John Cena with the caption: “You can’t see me.”. When I show it to people, they respond: “What tattoo, where?”.

Imagine being in your first day at the lab and your boss asks you to hold his invisibility cloak

I actually tried building sound-metmaterial with Coke cans for my physics project 10 years ago… so cool to see this video!

[ThrillSeeker]

Did they deceive Death into giving it to them?

[awesomehpt]

Why not just put a magic ring on? I saw it happen for real in a documentary called lord of the rings

[cutetwirll]

Wow! I'm learning about waves in science, and I remember doing a reflection and refraction experiment. This video is so interesting.

Joke's on you, Harry! I've upgraded with infra-red vision!

That rabbit seemed so nice and cute 🙂🐰

[starsose]

This is so cool! I loved how you guys explained each technique in a simple way. The animation looks like it took a lot of work though 😬😬😬

[Adventurealliancekerala]

Invisibility tech is cool and all, but I’m just here for the awkward fails when it glitches.

[intellectsteps]

This video really opened my eyes to a new perspective on life. Thank you for sharing!

I was not expecting to see a MTG card's flavor text in a TED-Ed video

[vginsprdsobepr]

The temptation to steal money if we were invisible is too strong to be ignored.

@2:23, the correct term in the language of physics should be "refractive indices", not " refractive indexes"

[time_warriors]

It's wild to think that invisibility cloaks might not just be a thing of fantasy anymore! This video really shows how close science is getting to making it a reality. 🤯 From bending light with metamaterials to other new technologies, it seems like we're stepping into a world of magic! 🧙‍♂✨

Thank you for all of your hard work! I love this channel.
