But I guess, "A Universe From Almost Entirely Empty Space Teeming With Quantum Activity" isn't as punchy of a book title.
I wasn't certain whether Lawrence or the media were pushing the nothing line.
He seemed to go aloing with it and then he didn't.
I guess it goes back to defining nothing as something relative.

But when they decay, what happens is the nucleus splits and we get two or more other nuclei: the matter didn't disappear. These heavy nuclei are formed by colliding two other large nuclei together. They don't just 'appear'.
True,
