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.
