Superkilonova! Double Detonation Of Two Bizarre Objects is The First of Its Kind

Correctly, “first time we’ve seen” one.
Now that my silly comment is out of the way - thank you for this extremely interesting video! I look forward to hearing more about double boom booms as more is learned! Thanks!
Personally, I prefer your "Double Boom Boom" name for it. 🤣
At the beginning you distinguish nova vs. supernova as white dwarf vs. massive star, but type Ia supernovae which (according to an AI query so maybe completely not right ) is about half of all known supernova and comes from a white dwarf. Yes, sorry, picky, but perhaps relevant: why couldn't it be a case of a supernova of a massive star with a closely orbiting white dwarf (or an orbiting pair of white dwarfs, with one flung in and one flung out by the supernova) then causing the kilonova. Seems more likely than a subsolar mass neutron star forming rapidly out of an accretion disk or core fission... I only had 2 years of undergraduate physics, but I don't see how that holds together.
The fact that so many elements on earth came directly from a supernova makes me wonder how likely it is we get hit by another supernova in the future
The change from red to blue is because it was feeling chilly afterwards
