Sabine tries to clarify the various meanings of "Big Bang" here, but one thing confused me more in her explanation... she says, that Einstein's theory "breaks down 10^-43 seconds before the mathematical singularity" and later "until we reach an energy density that roughly corresponds to that which the Large Hadron Collider probes, which brings us to about 10^-12 seconds before the hypothetical Big Bang Event". Given that she defines the "hypothetical Big Bang Event" as the mathematical singularity, shouldn't that be "after" rather than "before" in both cases?
- ccvannorman 4y agoit is my understanding that Sabine's intention is to say "as you go further back in time, approaching some singularity, Thing Happens at N seconds before you get all the way back to the singularity". So, I think you are correct, and her phrasing has caused this confusion around "before" and "after" terms.
