In the study, researchers from the Universities of York, Munich, and Cardiff explored the phenomenon known as backflow in particles that are not ‘free.’

Free quantum particles exist without any external forces, but the researchers note that this setting is idealized.

Through the new analysis, the researchers estimated the strength of backflow and found that it applies to all quantum particles, not just free ones.

You are very lucky that you ended up about the size that you are today, somewhere between one and ten feet tall and weighing somewhere between one and one thousand pounds. This is a very good size. Not to body shame, but if you were, say, a quadrillion times shorter and weighed a nonillion times less (that’s one followed by 30 zeros), that would be very inconvenient for you. Everything would be very inconvenient for you.

One thing you take for granted as a human-sized thing, for example, is that when you push things, they move forward. But a team of researchers realized that this is not necessarily the case if you zoom into the quantum world, where particles might decide to go backwards, no matter what kind of outside force you put on them.

Humanity is advancing rapidly towards a place where the news sounds an awful lot like science fiction. In fact, yesterday, Chinese scientists reported that they “teleported” a photon over hundreds of miles using a “quantum satellite.” But this isn’t Star Trek. It’s the real world.

Which happens to mean it’s a lot less exciting than Star Trek-style teleportation, unfortunately. But it’s still really cool, I promise!
