Universes. Is one a sign of others?

[luckyme]

One implies more.
When I first run across a new (to me ) situation, entity, process, I tend to assume it isn't unique and that it's existence suggests others with related properties rather than it in the only example of that type in the universe.
Does such thinking apply to the universe I know itself. Having stumbled across this universe, it suggests to me that 'universes of some sort are possible', not 'boy, this is obviously the only one of this type of thing that could occur'.

Straighten me out.
