Plastic Fantastic: How the Biggest Fraud in Physics Shook the Scientific World
Okay, kiddo. So, scientists really like to study the tiny, tiny things that make up everything in the universe. These tiny things are called subatomic particles. One of these particles is called a neutrino.
A long time ago, some scientists thought they found something very interesting about neutrinos. They discovered that sometimes, when neutrinos move around, they change into a different type of neutrino.
This was a big deal because it meant that neutrinos had a very, very small amount of mass. And at the time, scientists thought that neutrinos didn't have any mass at all.
But then, another group of scientists wanted to replicate this experiment and see if they could find the same thing. They built a big experiment called the Oscillation Project with Emulsion-Tracking Apparatus, or OPERA for short. They used a big machine called a particle accelerator to send neutrinos from one place to another and see if they changed.
But when they did this experiment, they found something very strange. According to their experiment, the neutrinos were moving faster than they were supposed to. And not just a little faster, but a LOT faster. This was a big surprise, because it seemed to break one of the basic laws of physics, which says that nothing can move faster than the speed of light.
Everyone was excited, but also skeptical. So the scientists did the experiment again, and again, and again. They made sure everything was working perfectly. But every time, they got the same result - the neutrinos were moving faster than they should.
But then, something very embarrassing happened. Another group of scientists came along and said that the OPERA scientists had made a mistake. They had forgotten to account for some things in their experiment that were slowing down the neutrinos.
It turned out, the OPERA scientists had been using a kind of fiber optic cable to send signals from one end to the other. And this cable was made out of plastic. And the plastic cable was causing the signals to arrive a little bit early - which made it look like the neutrinos were moving faster than they actually were.
So in the end, it turned out that the "faster than light" neutrinos were just a mistake. The OPERA scientists had accidentally used a plastic cable and it had messed up their experiment. It was a big embarrassment for them, but it's also an important reminder that scientists need to be very careful and make sure they're not making mistakes before they make big claims.
