Double-Slit Experiment in Time, Not Space

TheMatt writes "Thomas Young's double-slit experiment is a classic experiment that helped establish the wave-like nature of light. Since then, it has been done with atoms, buckyballs, and biomolecules. It has even been seen in a single molecule, and the single electron version was voted the most beautiful experiment by Physics World readers (covered previously on Slashdot). Now, PhysicsWeb is reporting that Gerhard Paulus and coworkers have conducted the double-slit experiment using a double-slit in time, not space. The "slit" was a crafted femtosecond pulse consisting of one-and-a-half cycles--say, two maxima and one minima--passed through an argon gas. Each maxima has a probability of ionizing an argon atom and producing an electron. The electrons were accelerated to a detector which observed an interference pattern since the detector had no idea which maximum produced the electron."

    Apparently great minds don't know latin. "Minima" is the plural of "minimum", so it's 2 maxima and 1 minimum.

    I would say YES. Because regardless of where two particals are in relation to eachother, there is always some form of time dilation going on. It may be so minute to detect, but I'm sure it goes on regardless if two particles are a few atoms apart or a solarsystem appart. The only difference in the dilation is "how much"
