What is String Theory?

Brian Greene explains the basic idea of String Theory in under 3 minutes. Thirty-five years ago string theory took physics by storm, promising the coveted unified theory of nature’s forces that Einstein valiantly sought but never found. In the intervening decades, string theory has brought a collection of mind-boggling possibilities into the lexicon of mainstream thinking—extra dimensions of space, holographic worlds, and multiple universes. Some researchers view these developments as symptoms of string theory having lost its way. Others argue that string theory, although very much still a work in progress, is revealing stunning new qualities of reality. Join leading minds in theoretical physics for a whirlwind ride through the twists and turns of string theory—its past, its future, and what it tells us about the search for the universe’s final theory.

If all physics teacher explain physics like this, i think human civilization will jump to the next level

[crazymaniac]

One of the best graphical representations I have seen!

Whoever edited this deserves a raise.
The simple explanation of the string theory itself deserves an Oscar in the category of "Making complicated stuff digestible for mortals"
But the guy who edited everything so we could not only listen but also see what's going on is a true genius.
Incredibly well made, well done

Holy shit! I do see lot of white strings when I peel off an orange.

[Proloyable]

Whoever made the animations need a raise!!!

[sunshine-uipr]

This is what online school should have looked like

[rexanator]

One of the best and clearest visual explanations on youtube!

But and then, what is the string made off? Let's zoom in some more.

Finally I understood what Sheldon used to work on...

As a musician, the thought that the Universe is made up of vibrating Strings makes a lot of sense and is also the most beautiful idea anyone has ever had. It translates to us living Inside the works of the most unfathomable orchestra. I'm in awe.

Best string theory explanation video under 3 minutes I've ever seen.

Props to the editor, I’m an editor so I can respect another fellow editor’s hard work.

[Threedog]

Well damn, after watching videos trying to explain string theory for YEARS, someone finally dumbs it down enough for me to grasp. Thank you.

[jeffreytiangco]

The only explanation that finally let's me understand what is string theory in simple terms. Thank you for this.

Parents: “Son, we’re not made of money.”
Son: “Hold on, let me pull some strings.”

[shahidjilani]

This visualisation literally blew up my mind! String theory explained in just two-and-half minutes. Brilliant!

[sinebar]

I've always been reluctant to go down the string theory rabbit hole because it sounded intimidating. This video made it easy to understand. Good job Brian!

[angeleyes]

This is why I LOVE science... He kept repeating "If, If, If"... instead of saying this is Truth and anyone who disagrees is WRONG!
