Hmm. "...the team ran simulations of the evolution of the shockwaves emanating from supernovae explosions over several million years." I expect that, to be accurate, such computer models would have to be prepared and executed very carefully. (I create much simpler physics models, and yet I always have to worry about possible errors.) It will be interesting to see if this model stands the test of time.

Agreed. Running different computer models at radically different length and time scales is required for these results. It's a bit of a black art.
