Wasn’t as super as hoped. That’s how experimentation works, that’s how knowledge grows, sometimes it doesn’t work out, but that not working out adds to the pile of knowledge that eventually DOES work out.
Yeah, but here’s the thing, everything of higher number than Americium is unstable and short-lived [even Americium is suspect].
What makes us (science) think that ever-higher e-numbers will be stable for more than a few microseconds? What does it contribute to the physio-chemical world other than “GEE, LOOK WHAT I DID!” ?
