How can we say there is no time before Big Bang? Matter i think i understand but how time cant exist before big bang?
In: Planetary Science
Any question regarding something prior to the big bang is inherently speculation. It can’t be answered, as all laws of physics breakdown as we approach the first nanoseconds of the big bang. There is no way to tell if there was anything prior to it. We have no way to tell if time worked differently, if physics worked differently.
From a purely logistical standpoint, having the big bang as the start of time also makes a lot of sense. Since the singularity serves as an information event horizon, we can’t measure anything prior (if there is a prior). So we have the start of time be from the big bang, 13.8 billion years ago, and everything counts forward from there and we dont have consider things like “negative time”.
