But there *is* a way to find the center of the galaxy, isnt there? We devised that way even before actually observing the center of the galaxy.

Do you have any method of figuring out where that "Tipperary" is? How would we find it and prove the theory correct? This is a necessary part of devising a good scientific theory - figuring out the "How to prove it" and figuring out what would prove it WRONG.

Otherwise it's not quite relevant as a scientific theory.

How could we find this Tipperary? hypothetically, even.. lets say you have the most powerful telescope out there.. where would you look? how would you 'recognize' that you found it?
