There are trillions upon trillions (actually unknowably more) of paths taken every second in the universe.
----------------------------
If you get a drink of water before going out to work, everything has changed. The evolution line is disrupted. In one way, you just delay yourself from the universe by a few seconds. In another way, everything has moved massively.
If you look at an apple and think... since this apple has a shade of red on it, does that mean that if you put it in shade, it's actual colour will change? It will stay red, yet turn into a different shade of it. Thinking of that also delays everything by a few seconds, then thinking that you have delayed yourself or the universe (perspective wise) delays you from the evolving universe. However, trillions of paths are changed upon every movement. Every time you stop and think, cars are in a different position than they would be, people have walked several meters farther, which changes your life. Why? Think of the billions of coincidences you have every day. You may not notice them, but a one-in-a-billion chance will happen every second, since the earth has billions upon billion of objects and thoughts to have a coincidence with.
If one of those coincidences are disrupted, they all change. Reading this, it is possible that you have changed the world.
If you had not read this, when you and your lover have sex, maybe a genius would have been born, or maybe the opposite would have happened, as now it won't. If your mom would not have given that last fake moan, you would not have been born.
The thing is, with trillions upon trillions of coincidences happening to you every step you take, how can you be so sure of something in the future?
Since you have read this, when you cross the street, each car will have a chain reaction, one person having one or more of five senses aware, which will continue to spread until final person/people don't have any of five senses triggered, consciously or not.
The chance of a car hitting you or anybody else when you walk across the street will highly differ, whether the chances go up or down (from car to car). But then, the reaction continues. Since one of the people have had their sense distracted, when they arrive home, since they arrived one second earlier or later, they will say hi to their lover 1 second later or earlier, changing billions of coincidences and pathways in his life, which will start back at my second paragraph.
One moment of wait, and you spread your coincidence change far faster than a germ.
It is funny how relativity in the form of coincidences can change so violently without us being aware of it.
