Good explanation, but he didn't stress enough what the string itself is... energy. In a nutshell, everything started with and is made from energy. Since energy cannot be made or destroyed, the universe is just the sum of all the energy from the Big Bang.

Pure mathematics, with more than 40 years so far and no connections yet made with the empirical world.

New way of thinking and why dark matter / dark energy . It never existed - 10d 6Dfrozen 1/3 flex , geometry space time only .

And here is in one sentence: string theory optimizes internal mathematical elegance at the cost of operational contact, making it stable as an abstraction but untested as a description of reality.

Obsolete theory now

I’m sorry but this is nothing more than a fancy visualization of an introduction to the basic idea of string theory - that all elementary particles are derived from strings. The first half (70+ seconds) of the video is about classic theory, and then 50 seconds on how does string theory go one step further, followed by 20 seconds of examples. How exact did it “explain” the string theory?

Oh Brian - You're so dramatic! Nice! - But no cigar for string theory. You will eventually learn Hierarchy of Energy theory... That time can be sooner or it can be later, BUT it will be! String theory has some good components but it still misses the big picture.

String theory got lot of momentum during our PhD days, I do believe some of the empirical status is still tough to achieve, our physics and math and spiritual understanding are not there yet.

“Nothing but” is a risky phrase. There is such a thing as excessive parsimony.

Dancing Cosmic Symphony of Strings, So in a nut shell Universe is a like a ball room with particles dancing to certain preset vibrations that they will respond to.

Didn't string theory fall pit of favor?

Physics is the magic trick. They show you non sense equations and then nobody checks the math. Meanwhile they invent quantum physics because it was getting to difficult trying to explain why standard physics wasn’t working.

You still haven't explained why it's called an Orange. A Banana is NOT called a yellow. Explain it!

In video games and simulations the system only renders what is needed to save computational power. Physicists are measuring 'the real world' with a VR headset on and not realizing they are in the Matrix.

Wow ~it’s almost poetic blasphemy~the most pedestrian object in your kitchen becomes a portal to a cosmic symphony played on strings too small to ever touch~yet orchestrating gravity light matter time itself

Perhaps not so theoretical 20 years later! Becoming more experimental?

Why stop now We keep being told the final boss is 'Nothing' Then somebody looks closer and ¡Hey presto! Nothing is composed of tiny Somethings Then the adjunct professors all start chanting that way down in there the rules all change and we can no longer talk about time or space
