What's the highest energy density that has been achieved

>>9133330
Everything explodes under the right conditions.

But black holes have the highest densities inside them, and they can be made not to explode for trillions of trillions of trillions of trillions of trillions of trillions of trillions of years, roughly speaking. (if you know an easier way of writting 10^80, let me know)

human made? concentrated uranium...there are two payloads that separated do not undergo nuclear fission but when combined ta da

wew lad

when you consider mass-energy equivalence, all objects possess enormous energy densities. A black hole is the highest of these, but that's even worse than an explosion. So I would say osmium is the most energy-dense thing out there. Maybe let it build up a tremendous charge at extreme temperatures, but those are statistically insignificant compared to its mass-energy
