Join Neil deGrasse Tyson as he explores the dark mysteries of our cosmos, from the infinitesimal electron to the higher dimensions of the multiverse. You’ll find out whether photons have mass, why the Moon doesn’t really orbit the Earth, and how many stars are born each day in our galaxy’s stellar nurseries.


Neil explains how neutron stars could become black holes and why space is anything but dark, ablaze in microwaves and other energy beyond visible light. At times, the science borders on the philosophical, as when Neil proclaims, “We are the singularity writ large across the dimensions of the cosmos.”

But there’s plenty of physics, too, as your own personal astrophysicist answers Cosmic Queries about the speed of gravity, the difference between “aether” and the Higgs field, what dark flow has to do with galactic expansion, and how long we have until we crash into the Andromeda galaxy.
