The Table should not include elements with existences measured in milliseconds.

“The Table should not include elements with existences measured in milliseconds.”

Why not?

[VanShuyten]

Actually, some theorize that there are stable, super-heavy elements waiting to be created.

The Table should not include elements with existences measured in milliseconds.

In particle physics, a millisecond is an eternity. If you're talking about planck time, you'd have a better argument. That said, even though these elements exist for very short periods of time, you can learn how they behave and interact and it helps verify the physics models.

Even further beyond that is that once it is known how these elements will behave, new interactions with other elements may become possible that creates something very desirable.

To reject the existence of these things because they only exist in an accelerator or only existed in the first few femtoseconds of the universe is silly and shortsighted.
