For example, whoever proposed blackholes. How did they think of it? Was it through an equation and what about this equation made the person think up the idea of a blackhole? If not through an equation, how was it figured out?

Same for wormholes, how were they proposed? Through an equation or combonation of theories or what?

Again, same for the idea of tachyons. Was there an equation they were derived from or combonation of theories or what.

Forgive me if the answer to these questions are too complex for an online post. Maybe a website or book recommendation is in order? I just really would like to know how people think up these kinds of things without us actually observing them (especially tachyons as something that goes >c doesnt sound like something that can be derived from an equation or two).
