All IMO of course.
As far as I can tell, they're based off of Newton's Laws of Motion. Come on man, that's SOOOO old school, everyone know's Einstien is where its at.
Seriously though, Objects at Rest tend to stay at rest, objects in motion tend to stay in motion, stuff on Earth falls at 9.8 m/s^2 until it hits terminal velocity, etc. all that stuff can be calculated on a core of a dual core proc, or with the spare cycles on your GPU.
When it can calculate time dilation in my space sims, that's when I'll buy one.
(this would allow me to whip around the sun and go FTL without a warp field on, allowing me to go back in time on my Star Trek Legacy missions when I screw something up)
