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
We simply don’t know.
Our laws of physics stop working during the big bang, and some people think the laws got created by the big bang.
But it’s all speculative. There could have been time before just like we know it. There could have been time that worked completely differently (for example 2D time where travelling backwards in time is very easy), and there could be an entirely different kind of physics that doesn’t need time. Or existence itself wasn’t a thing.
The only the we know is that our current understanding of physics did NOT apply
