But the elements at the current end of the table are so unstable that they decay almost as soon as they’re created in our particle accelerators. Have we reached the end of the line of discoverable elements? There are new rows of the periodic table to unlock, and more stable versions of known heavy elements to synthesize—and while our accelerators are coming up short, astronomers have found a strange cosmic phenomenon that may populate the periodic table beyond our wildest dreams.

3:40 Bismuth-209: I might not be stable forever, but I think I deserve an honorable mention, with my half-life of 19 quintillion years...

I once vacationed on the Island of Stability. It was boring -- nothing ever happened.

I used to joke that if you took a neutral neutron star, threw in a proton, then put an electron in orbit; then you'd have the only gravitationally bound very heavy isotope of hydrogen. Maybe it wasn't really a joke?

Bismuth fascinates me. I have a few crystals of it on my desk. It has no stable isotopes, but it's _so close_ to stability it has a half-life far longer than the age of the universe -- yet at the same time, a lump of it will do the near-impossible and occasionally kick out a positron.

Whenever I hear the word, "kilonova" imagine a bossa nova song that's so good it's killer.

Ah, so trying to take a picture of a kilonova is just like taking a video of my dog doing something funny. By the time I get the camera rolling, the best part is over. 😞

I'm surprised you didn't mention Przybylski's Star! Spectral analysis of this star suggests many heavy elements are present such as uranium and ytterbium. This could very well be remnants of a kilonova explosion which produced island of stability elements which decayed into these rarer daughter elements.

Finally! An episode of Spacetime I understood from start to finish.

I always struggled with Chemistry back at school, to the point where I didn't even really understood what the numbers in front of the molecules's name actually denote, how they correlate, and how one could deduce information on the molecule's stability (or lack thereof) from them. Of course I was later in my adult life able to find out that information through self-study, BUT: your brief explanation with visual aids was _the_ best, most succinct yet intuitive explanation of the this framework that I've seen to date. Very well done, and this also demonstrates precisely why I love this channel... you neither put on airs aka "Everyone _should_ know that by heart", nor do you dumb it down to the lowest common denominator; a great balance, and inspiring for me as an on/off tutor for Y3 to Y8 kids.
