The Cosmic Symphony of Strings

Imagine I have a beautiful tree that's filled with oranges. And I ask myself, "What is the orange

made of?" How do I answer that question? Well, I want to look deeply

inside the orange, so I magnify it. And I magnify it again, and if I keep on

doing it, deep inside, sooner or later I begin to see molecules come into view.

But molecules are not the end of the story because the molecules, I can enlarge them.

And if I make them big enough deep inside, I begin to see atoms. Atoms are not the

end of the story too, because we have electrons zooming around the nucleus,

deep inside mostly empty space in the atom, but deep inside we see the nucleus.
