Time Capsule

Why is this called “Time Capsule”? Are you aware that capsule is defined as a small container, especially a round or cylindrical one? So what time is it inside the capsule?

Of course I’m aware of the meaning of capsule. For me, the whole idea of a time capsule is irrelevant, because of black holes.

OK now I’m really confused. Do you mean whole idea or hole in time?

Maybe I’m talking about a hole in one, and I don’t mean golf.

I sense that things are going off the rails. I don’t even know what to ask you, and that’s unusual for me.
