WHAT DO SCIENTISTS MEAN NOW BY “THE BIG BANG”? Ethan Siegel on the aptly named startswithabang blog explained in this post on February 10 the implications of the new mathematical theory I posted on a few minutes ago. He describes that paper as “simply another drop in the ocean” of debate about where space and time come from. Siegel says that the definition of the Big Bang which is accepted is: “The hot, dense, expanding state that our observable Universe emerged from, that expanded, slowed, cooled, and gave rise to elements, atoms, stars, molecules, planets, and eventually us”. Siegal concludes: “The biggest thing you should learn from all this? That ‘the Big Bang’ represents where everything we see in the Universe comes from, but it is not the very beginning of the Universe anymore.”
Siegel’s post explains very clearly things that I will never understand. It seems, however, that what I marveled at in that first post still holds true. We have empirical evidence of something that happened 13.8 billion years ago. Everything we experience in the universe comes from that moment.
