I was reading "A Universe from Nothing"written by theoretical physicist and cosmologist, Lawrence Maxwell Krauss, I only just started reading it but I was really interested in a specific chapter so I skipped to it which is chapter 9 "Nothing Is Something" and it basically states, unless I mistook it having not read all the previous chapters, that something can come from nothing. It goes on to say in a brief summary "that something can arise from empty space precisely because the energetics of empty space, in the presence of gravity, are not what common sense would have guided us to suspect before we discovered the underlying laws of nature."

I cant remember who said that the universe cant come from nothing but I'm pretty sure I saw it on this site a while back, so I'm curious why is it wrong to think the universe came from nothing?
