I’m just glad we finally, today for some reason, have the ability to determine what will and won’t ever be possible with physics. It’s also crazy to me that we know fusion so thoroughly we cannot reliably perform it but we know it’s possible to do but we also know it’s impossible to do for extended periods.

You should inform nuclear physicists and engineers of your new-to-mankind knowledge.

Did you know we once argued over whether or not to close the patent office because “everything had already been invented”? This isn’t the Galileo concept, it’s recognizing we’ve only been doing global hard science as a species for like 50 years.
