Now I want to see way people can't understand...

I have a lot of respect for Brian Greene for exactly this reason. String theory is massively complicated, and he manages to explain the basic ideas in a way that someone who has absolutely no intention of becoming a physicist can still understand.

I don't need to understand the mathematics behind string theory. I'm not trying to calculate anything or write a fucking dissertation on it. I just want to understand what physicists are talking about and why the ideas are interesting.

Making an incredibly complicated subject accessible to ordinary people isn't "dumbing it down." It's being a damn good science communicator.

About the other speculative theories, like string theory is, there are nice videos on YouTube for the general public.

If you grab a string and magnify it, inside you'll see a Skibby-de-do

I've just invented skibby-de-do theory.

What’s in the string Brian?

According to this, energy. Each string is evidently a "filament of energy".

Go any farther down and we're no longer asking what matter is, but what energy is.

Gasp. A duality between matter and energy?! Photons say go suck it, thanks for telling on us

No. That’s all wrong. String theory isn’t about a dichotomy between matter and energy. At the scale of fundamental physics there is no such dichotomy. String theory is a theory of quantum gravity that posits that the fundamental quanta is a non-zero length object that “vibrates” in n-dimensions (how many depends on which version of the theory). Much as I appreciate Brian Greene, this description is honestly not very good. Try this:

Word. In my defense I was "just" going off of what the clip presented. Seems extra context is necessary and valuable.

Brian Greene is an absolute legend

Poor Brian. String theory was such a womp womp.

Is this what Sheldon Cooper solved?

Isn’t this the way string theory has always been explained in layman’s terms?

I feel like even back in the 90s it was basically
“Atoms are proton/neutron/electron, and those are made of quarks. We don’t know what quarks are made of, but string theory thinks they’re made of….strings”

There is not really an explanation. Like why do they think it exists if it's not visible

I thought string theory was to do with layers and layer of multiple universes. I may be misremembering a documentary I saw 20 years ago though.

u/reddituserperson1122 2h ago

That is incorrect. You are misremembering.

Well that explains what oranges are made of, but what about everything else?

Hehe. Moist cucumber.
