I also am not a physicist. I used to have a fascination with all this stuff and read the classic astronomical and philosophical works from Aristotle through Newton. I would say at the time of Copernicus is when the church and science really went in different directions ... and henceforth there was a lot more reading to be done to keep up!
Einstein wrote a book for you http://www.amazon.com/Relativity-Spe.../dp/1891396307
Do you think light moves in Zero Gravity?
Both light and gravity are properties in this universe. As it's impossible to escape gravity I don't think anyone would know anything about that....people don't seem to want to talk about other universes LOL.
Of course there is gravity in space. Just some places experience a very small effect from it.

"Eh, Phil. That's one I happen to agree with."
I've made up my mind. Don't confuse me with the facts.
A wise man doesn't waste effort telling the world he's wise. If it's true, it will be self-evident.

Sorry, I thought I was editing my post (a simple spelling correction) but ended up double posting. Now I'm past the 10 minute limit and I can't delete the incorrect one.
Think of it as two really hot chick twins- One gets into a rocket ship as and travels in space- the other waits patiently. The space traveler intends to ride at 99.9999999% the speed of light for 10 minutes.
The twin on the rocket ship looks at her watch, and 10 minutes goes by and returns to earth. To this person, the trip felt like lasted 10 minutes. The one waiting on earth sees 80 years go by. The faster to the speed of light you travel, time slows down- unless you are the actual traveler
