The answer would be "We do not know". As to the ages of other universes you might not even be able to say that they are "older" or not. Time is a trait of our universe. We do not even know if other universes would have it, but if they had time their time would not be our time. So you could not really say that it is "older".Ok SZ, a thought experiment, given that this timespace universe had a beginning, about which we do not know how or why, hypothetically there is no reason why there are not other timespace universes in existence that began the same way. So the question arises, what separates these different timespace universes.
And furthermore, hypothetically let's say one of these other timespace universes is 20 billion years old, how would you refer to them in terms of one beginning (forgive me but for the moment I willl use the only word I can think of that I can think of to make sense) 'before' the other, is it older and earlier?
You are making the mistake of assuming that our time is universal. Just think of separate universes as separate number lines all of them starting from their own "0".
