Damn, that’s cool. Everybody always told me that as elements get more massive, they get less stable. Turns out that doesn’t have to be the case. Heavier elements could actually get stabler, they speculate that there could be yet heavier elements out there with day or year long half-lifes. Element 117 doesn’t seem to get you as far, though. More like a few milliseconds.
So, I guess, don’t let chemists tell you anything, there still might be room for Unobtainium (that doesn’t decay within milliseconds) in the periodic table :)
