That is assuming the are multiple timelines. There arent copies of you, its just everything is being affected more by time than you are. Remember that time and space are a continium. Think of a black hole. The closer you get to the black hole, the stronger the gravity. Get really close and not even light can escape. A black hole like this one has a dramatic effect on time just like it does on gravity, slowing it down far more than anything else in the galaxy. That makes it a natural time machine.

Contradicting that, i just found this out:

When you think about light as a collection of photons, the bands created on a screen when you shine a light through a diffraction grating actually represent the statistical probability that a photon will hit that part of the screen.

This is easier to understand if you allow only a few photons through to the slits. If you only have one slit, the screen would look like this:

The photons will hit the screen mostly in the direct line of sight
from the slit. Thus, the probability is higher that a photon will hit
in the direct line of sight of the slit than in places far away from the slit.

If you have two slits, the probability changes because of interference:

A higher concentration of 
photons exists at the bands.

But what if you only let one photon at a time go through a two slit grating? You would expect the scatter of photons on the screen to look like the scatter from a one slit grating, since a single photon has nothing to interfere with. After all, if a single photon goes through one slit, how can it "know" that the other slit even exists?

But, to the great surprise of quantum physicists, the scatter of the photons let through one at a time is identical to the scatter of the photons let through all at once! The photon did somehow "know" about the other slit. So which slit does a single photon go through? The answer is the photon goes through both slits at the same time. The photon(according to modern theory) becomes two ghost photons, allowing a single photon to interfere with itself. Hard to imagine? You're in good company.
