I find it to be an interesting concept, since what you describe does tie into chaos theory. Though I find the theory itself to be a constant amusement to me (weatherpeople will never be 100% accurate according to the theory).
To be honest, what you said I believe is chaos theory / butterfly effect. The 'what if this hadn't / had happened' bit is basically the basic (but not scientific) definition.
Though 'trace' had me thinking in terms of the internet, where you also leave traces... unless you're a proxy-freak or use Tor or the like, and modify your computer to keep no records. ^_^

What I really was reffering to was physically leave a trace, not a internet type thing.
