Black Holes, String Theory and the Fundamental Laws of Nature with Andrew Strominger

What are black holes? What are they made of? What is string theory? Is everything we see just vibrations of strings? How are string theory and black holes related? What are the fundamental laws of Nature?

For decades, since the discovery of quantum mechanics and Einstein’s theory of relativity, scientists have been trying to combine the two perspectives of the world into one single unified theory. One of the results was string theory: where the strangeness of quantum reality and the weirdness of relativity theory come together and create something even more puzzling – a world with extra dimensions
.
String theory says that there is only one fundamental object in the universe: the string. Much like the strings in a guitar give rise to different sounds when you pluck them, the strings of string theory give rise to the different constituents of the observed reality when you make them vibrate at different energies. Is everything in the world made of strings? If so, what is a black hole? SEE:
