My lord, who wrote this article?
Imperial College London physicists have discovered how to create matter from light - a feat thought impossible when the idea was first theorised 80 years ago.
They didn’t discover it, as they say in the same sentence this is an 80 year old theory, rather they demonstrated it in a lab rather than observing it in nature. That sentence also makes it sound like this process may have been considered impossible until they demonstrated it in the lab, and that is just not true.
Plus this stupid site clipboard hijaacks. Feh.
- mirimir 8y agoThe article implies that they "demonstrated it in a lab". But actually, they just imagined a way to do that. And as far as I can tell, it hasn't yet been tested. How is it that some physicists seem to talk about results of modeling as if they were experimental results?
