"I don't see how something like a massive star... can make a transition into something with as bizarre a structure as a gravastar."

As I recall, black holes were also considered bizarre and beyond liklihood when they were first proposed.

I wonder, though, if a molecular cloud has the same basic properties as a gravastar, yet in growing over time it has become more stable?

Black holes were first proposed long, long before Einstein and Hawkings were even born.
