Each and every day I learn something new. I was taught in material science that defects propagate at the speed of sound with a clear scientific reasoning. Now I see that this thesis has been disporved:
DOI: 10.1126/science.adh5563
And a BIG applause for the technique to actually measure the velocity in the diamond!

Does that mean it is actually faster than the velocity of soundwaves in diamond?
I couldn't get that link to work.

It was reported here also:

@sonhouse saidNot really 🙂 New models are proposed and discussed.
@Ponderable
Have they figured out the physics involved yet?
