It's still Earth-bound "science" and "facts", the universe is such a big smurfing place that even the standard "laws" we adhere to can mean diddly squat.
Except that's not really true. There are only a small number of truly fundamental laws which contain a small number of physical constants. If you can confirm these are the same elsewhere as they are on earth, you automatically get any science derived from those laws (e.g. physics and chemistry, although not biology since you could in theory have a biology based on an alternative chemistry).
I believe as far as we can tell, these laws and physical constants are the same everywhere in the universe, and always have been.
