IIRC, current theory is that the universe is a little more than 13 billion years old.
IIRC, stars become supernova when they exhaust their supply of hydrogen.

How long does it take for a Megastar to exhaust its supply of hydrogen?
Is it surprising that this happened 13 billion years ago?

Hypergiant stars only have a lifetime of a few million years, so it’s not surprising that some were exploding 13 billion years ago.

Megastars burn through their fuel at a very rapid rate. For a Blue Giant star you are talking about only a few million years before it supernovas.
