If they are unrelated Lua states, they do not need to be locked from 
each other; the Lua interpreter does not use any globals at all. You 
may need to lock internal (i.e. non-Lua) datastructures; the lua_lock() 
mechanism will not help you with that.

I can't see what else you might mean by universes accessing each other. 
You cannot randomly access a Lua state's stack while that Lua state is 
actively running a script.
