Are cavities and gravities similar?

Question

they're both clingy

Answer 1

no.

Answer 2

Very similar; indeed, the last eight letters of both words are exactly the same.

Answer 3

And both can form black holes.

Answer 4

Cavities are never desirable (unless one is a s****t). Gravities is capable of being desirable, like when one wants to deliver water from a reservoir to a nearby city at a lower altitude.

On the other hand, gravities can be undesirable too. For instance, when you step out of an airplane without a parachute, gravities are not desirable. Thus cavities and gravities are similar in that they both share the possibility of being undesirable.
