Ok, how did people get -that- meaning first time?
I think considering such things simply beyond us is probably a very sensible standpoint. So you mean infinite, in the sense of "math"/intelligence? What does that have to do with time/space being at the same point?
And BTW it could not be infinite energy, which is just something in the nature of our own specific universe, i do not see how that could be possibly be relevant. You might aswel talk about impulse too, being relative. Why do you not add temperature and electric charge, electromagnetic fields.
