in the show the stargate's wormhole emits a good amount of light, i mean you cant make the event horizon itself do that (at least if the mod/minecraft work the way i think they do however i dont know much about java) anyway what about making the base block emit light when the wormhole is there

I'd love to do this unfortunately I haven't figure out a way to do so after a bunch of attempts.

Added to the to-do list.
