Why do we care about the heavy elements like 119 and 120 that decay in like .00002 seconds? What could we possibly use it for?

why do we care tho? to prove we can?

Producing and studying them allows us to constrain theoretical models of nuclear structure, and possibly atomic structure as well.

There are around 3000 known nuclear species and about 7000 predicted to exist. Many of these 4000 undiscovered nuclides are either producible using existing technology, or will be within the next few years.

Why *shouldn't* we study them?
