The headline goes a bit far. They postulate that some elements, e.g. silver, are the result of the fission of extraordinarily high atomic number elements. There are no actual observations of such elements.
- kstrauser 3y agoDo we have the technology to observe such elements if they could even possibly exist? I'd guess they'd be the sort of ephemera that would take a gazillion eV to form, then would decay a femtosecond later.[0] If so, creating an atom in the lab may be outside our engineering skills today.

- pfdietz 3y agoWe've made elements up to mass number 294. https://en.wikipedia.org/wiki/Superheavy_element https://en.wikipedia.org/wiki/Superheavy_element However, the specific isotopes made in the r-process are very neutron rich, right up to the neutron drip line, and I don't believe we've made many of them.
