I just did, and didn't see anything I violated. I could be wrong though, and would love to correct my behavior. I said it was absolutely crazy because if you go frame-by-frame there is literally a flash of white in a single frame, then the explosion. No build-up, no nothing. It happened within 3/24 of a second. If you make some estimate of the scale, you could use dimensional analysis to estimate the energy of the explosion. The time scales are a little large, but it could be done to probably two orders of magnitude.
