Well, in one way anything that happens, be it very small or very large "changes the future of the universe". "Changing the future" is a common sort of a phrase, but in fact it is a complete mis-statement. The future doesn't exist until after the event, so it can't be changed. What each event does is to set the universe in a particular state, which will affect all future states.

This of course assumes that predestination is not a valid concept. If the whole course of the universe is already determined then no event will affect the future.
