Philosophy is constrained by the questions asked and the concepts used. Certainly race, time, spirituality and antigravity exist under certain definitions of them.
If (under my definitions) you mean are there any particular consequences to any racially specific genetic traits, I'd so no since the affects are basically negligible.
I think that human concepts talk about something we call time. Whatever this thing is, we call it time and it exists.
A spiritual world (i.e. a place in time which is none material) might exist, but I've never seen it and have no good reason to make an inference to its existence.
As for antigravity, I've seen it done (on TV), correctly charge something (with huge amounts of electricity) and it will float.
If you term a force which will oppose gravity "antigravity" then I can create it by lifting a finger. Floating is done regularly with two rather weak magnets with like poles facing each other. Actual negative gravity may be active with anti-matter. I am not sure.
I've done some quick research and it seems matter and anti-matter most likely both react the same to gravity. Since matter and antimatter react extremely violently when put in contact actual experiment is difficult.
