    CO2 from champagne bottles can form shock waves like those seen in rocket exhaust

    Popping a bottle of bubbly releases a plume of dry ice that bears a visible type of shock wave called a Mach disk.

    Can time travel survive a theory of everything?

    It’s not yet clear whether a theory that unites general relativity and quantum mechanics would permit time travel.

    A new experiment slashes the maximum possible mass of tiny neutrinos

    The KATRIN experiment suggests that the tiny subatomic particles have masses a minuscule fraction of an electron’s.

    How an astrophysicist chased a star from the Halo games to real life

    Julián Alvarado Gómez has devoted his career to a star called Iota Horologii. His former life as a Halo video gamer helps fuel that devotion.

    Gravitational waves from a ringing black hole support the no-hair theorem

    A new study of gravitational waves from merging black holes agrees with the predictions of the general theory of relativity.

    Einstein’s general relativity reveals new features of a pulsar

    Measurements that rely on the physicist’s theory of gravity are letting astronomers view a pulsar in ‘a whole new way.’
