Lara Anderson says anomaly cancellation points string theory to ten dimensions

What was said

"And what they found is that all of this quantum uncertainty, this sort of wiggling and violation of these these principles that we think should hold magically cancels out when you have 10 dimensions. Um these quantum anomalies cancel exactly. So the theory becomes really robust and really rigid."

Lara Anderson says early string-theory work found quantum anomalies cancel only in ten dimensions, avoiding mathematical inconsistency. She argues that this makes the framework internally consistent before asking what it predicts about the Universe.
