LK-99 may sound like little more than a Star Wars extra, but has been tipped as a once-in-a-lifetime physics breakthrough
But like Clark Kent, sometimes a normal conductor isn't enough. Just as Clark has to put up with glasses and overly tight shirts, copper has to deal with resistance, meaning some electrical energy can be lost as it travels.When Clark swaps his journalist attire for some spandex and a cape, he flies freely through the sky and pretty much nothing can stop him. Superconductors are just as powerful: materials that can carry electricity with no resistance.
The only place you're likely to have come across them if you're not a physicist is if you've had an MRI scan, where those aforementioned magnets are vital to processing accurate medical imaging. The other key attribute lacking from most superconducting materials is the ability to make a practical wire out of it, which is what's made copper such a good everyday conductor for so many years.Just one of the superconductor coils used to form a giant magnet for the world's most powerful MRI scannerIt is said to be a relatively common material called lead apatite, bolstered by some copper atoms.
Wide-eyed optimists on social media were quick to suggest we were looking at the future of trains , but scientists haven't been so quick to drum up the hype.Oxford University professors have described the findings as"interesting, but not yet wholly convincing". Dr Ainslie says:"We're cautious about these kinds of claims. It would be fantastic, but extraordinary claims require extraordinary proof. We're waiting to see what happens with the replication efforts going on at the moment.Image:
