Rosenbaum points out how some scientists fudge "nothing" so that they can "prove" the universe erupted from nothing. But Rosenbaum is quick to catch the bogus arguments, such as the one that claims a vacuum is the same as nothing. It's not. He also blows up the argument presented by one eminent scientist that the universe could have exploded from a single gram of matter, begging the obvious question, where did the gram of matter come from.
Rosenbaum also points out how some scientists point to the "laws" of quantum physics to explain something from nothing, except there is no proof that the laws existed before or after the Big
The best we can do is ask how anything came to exist at all.
