In simpler terms, a person, thing, entity, or event exists both in your universe and in ours, in a similar form, which is how we found you. And in some way, you're directly connected to one of those - the constant might even be you, but I can't say that for certain right now, because your signal is still a bit off. That's the best I can explain it... It doesn't make a lot of sense to me, either, I'll admit. My Head Engineer understands it better than I do, and he's run off to ADS again...
Are there any questions you have? We'd like to know more about your universe for research purposes, but I understand it might be daunting for a complete stranger to just start asking you things. So far, all the people who've responded to our message have known who I am already.
