I don't get this.
​
... In the case of the universe, there was no time when the universe did not exist -- there was no "before" the universe since there was no "time." ...
​
It seems to imply that mass/energy is required for time to exist. Could someone explain it or give me some links?

Try to look at it like this: What is north of the north pole?
That's the same question as asking: What happened before the big bang?
​
Time is a part of the universe, itself, not something that the universe exists within. Time doesn't exist if the universe doesn't exist.
​
Thanks, I guess I was just thinking of the big bang as the source of matter in the universe and not time as well. So my question now is why do we assume the big bang created time. In other words is time a function of matter and energy or could there be some other type of universe with a whole bunch of time but no matter or energy.
