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