Alright, so before I start off, I just want to say that I'm not very far into my physics career, but as I was reading on the forums here, I got to thinking about something...but, before I say my thoughts, I want to apologize if it's a stupid question. But here it goes: So, I was reading on the relativity forums today about how space and time are linked, which I think understand (or, understand as much as anyone can). I was wondering something; there is a force on something if it is accelerating (F=ma). Time is going forward at 1 sec/sec at a constant rate (far as I know?). If time were accelerating somehow...not exactly sure, but if it were, would that apply a force? I mean...if time had a constant positive acceleartion throughout the universe, would everything in the universe be pushed backwards in time (equal and opposite reaction, and all)? So I guess what I'm asking is can time be dealt with the same way as a spatial dimention? Sorry for maybe an odd question, but something that had been on my mind at work all day. Thank you!
