[rnsmkgjj] Matter disappearing

Astronomy has a few nice examples of large quantities of matter turning into energy.

Of course, stellar nuclear fusion.

A supernova converts a large amount of the progenitor star into neutrinos.  While technically not massless, because neutrinos interact so little with anything, it seems like mass just disappeared.

In a black hole merger, a significant amount of mass gets radiated away as gravitational waves.
