There will be much discussion of this.
Time did not begin with the Big Bang - Stephen Hawking
"The boundary condition of the universe ... is that it has no boundary," Hawking tells the
National Geographic's
Star Talk show this weekend.
In other words, there is no time before time began as time was always there.
Hawking's an ass that has already been proven wrong before. He mainly gets a free ride because of his disability because he promotes public interest in the field..
Time is a function of space-time, and without space you cannot have time since time is an extension of space. To say that time never began (was always there) is the same as saying that space was always there, which violates every accepted principle of the creation of the universe, that it all expanded from a point of creation.
Before the Big Bang, there was no space for time to occur in, in any conventional reference that we can know. Whatever occurred to spark creation came from another plane, another dimension, and no one, not even Hawking understands it, much less can say what boundaries were and were not there. It's all just a big guess.
