Also, the actual destruction happens much slower than that.

The fastest explosive on earth detonates at a speed of just over 6 miles per second, about a 300th of 1 percent of lightspeed. I very much doubt anything hit by mere photons could deflagrate quicker unless there was an absolutely staggering amount of energy being dumped into it.

Yup. I guess "able to overheat targets at moderate speed" just didn't sound like an exciting enough headline.

Other journalists list a per-shot price in the headline, which is the right thing to emphasise. TBF it's one of the first things mentioned in the article.

All I want is sharks with frickin' Lazer beams, is that so hard?
