errr, pardon the interruption. The term used in Physics is "spacetime'" not "space-time"  Search "Einstein's Field Equations"

Quantum321 seems to prefer the hyphen. I have not seen it used by any others. Doesn't seem important either.

I don't believe it is important at all....spacetime, space-time or space/time, it all means the same thing.

I think early versions of joined words have hyphens and then eventually it disappears.

I sometimes hyphenate and sometimes not. (I usually avoid hyphens on the phone cos it takes more typing)
