There are aliens out there.. You have been warned, and it's not us. They guard the artifacts.. oh wait.. what artifacts? Pretend I didn't say anything...

At any rate I think you need to be higher than tech level 4 to go through the center unmolested. There certainly won't be the uncovering the entire map in a few days.

3.3 eh? That's getting pretty close to the center. You could always fly a probe towards the milky center and find out what happens. I'm playing as VeriHm, and as ZarkWizard if I am testing something. For the most part you'll find me on as VeriHm. I have no special powers on that toon.
