Well, you've decided to get fancy with your wormholes, haven't you?
According to the totally-not-made-up laws of physics, if you create a big enough wormhole, you'll:
1. Disturb the fabric of spacetime in an epic way, possibly causing a nearby star to go "poof!"
2. Get stuck in a never-ending loop of wormhole maintenance, because, you know, they're a real pain to clean up after
3. Be hailed as a hero by the Physics Nobel Committee, because who doesn't love a good wormhole-themed trophy?
