Listen to these sounds of black holes merging and falling into one another and the "white noise" of the Big Bang. A TED Talk with Janna Levin that stirs the mind.
An astrophysicist who studies the shape of the universe, Janna Levin has also explored her science by writing a novel about two pivotal 20th-century mathematicians, Kurt Gödel and Alan Turing. Both men pushed at boundaries where mathematics presses on grand questions of meaning and purpose. Such questions, she says, help create the technologies that are now changing our sense of what it means to be human.
