space-and-time-picture

Professor Sir Colin John Humphreys of the University of Cambridge.

This is quite a nice article, although Sir Colin Humphreys holds a Christian faith his thinking does not exclude other religions.
Could the universe exist without God?  How might the answer depend on what “could” is taken to mean?  What are meanings of “necessity”?  Are there any unambiguous meanings of “necessity” between what is actual and what is logically possible?  Are there any meaningful so-called “synthetic necessities” or so-called “metaphysical necessities” that might be claimed to be in between?

Can space and time spontaneously appear from a quantum vacuum?  Is a quantum vacuum nothing? Is a universe from nothing compatible with an incredibly hot, dense, big bang origin?  Is how our universe started a purely scientific question? Is there any input from the Bible?
