I'm pretty sure you could claim the other side of the wormhole. As the simulated early turns are just simulating early carrier movements so since you can move a carrier through the wormhole you should be able to claim it the same way.The other reason i believe this to work is just think how screwed the wormhole race (sorry their name eludes me atm) would be if they couldn't claim territory through wormholes in the simulated early turns.
As for asteroid fields & supernovas. If you are the race that can stop in them you can claim them in the simulated turns otherwise you cannot claim them. You as you cannot put a command counter on the asteroid field legally even with antimass deflectors hence why you cannot claim them in the simulated early turns. Same thing with supernovas.
Easiest way to understand the rule. If you could legally put a command counter on that space via a 1 hex movement then you can claim that territory via simulated early turns.
