There is a wiki on pair-instability supernovas. Antimatter (in the form of positrons) is a key factor.

I just want to live long enough for space telescopes to evolve exponentially to observe kilonovas in the visual spectrum

I mean laser interferometers are an amazing advancement but just imagine seeing an earth-sized chunk of gold pop out of a kilonova (probably not my lifetime but eventually a human will see it happen)

Thank goodness this administration did not frack with Nancy Grace Roman Telescope, I thought the name alone would make them cancel it or rename it after him, wait maybe I shouldn't even mention that idea...
