Physicists have conducted a famous physics experiment for the first time using antimatter. If you’re new to quantum physics, you may want to watch this video where we cover the basics. Essentially, we’ve got two main ways of explaining the universe; one that works with our idea of gravity, and one that works on the quantum level. The problem is, they don’t agree with each other. Experimentalists and theorists are searching for the magic key that could resolve this paradox for us. What we like to call a “theory of everything”. Some think that the answer lies in a classic physics exercise called the double-slit experiment. Some think that the answer lies in a classic physics exercise called the double-slit experiment.
Here’s how it works: you have a sheet with two slits in it. Behind that, a blank sheet. You have your source of matter, let’s say...cheese balls. If you fire the cheese balls through the double slit sheet, you should get two lines of orange cheese ball dust on that back sheet. Simple enough. But let’s say instead of cheese balls we want to fire something that moves in a wave, like sound. Instead of getting two slit-like impressions on the back sheet, you get a pattern of several lines. That’s because the sound waves, as they’re passing through the slits, bounce off each other and cancel each other out in what’s called an interference pattern.
