@The Dude phil,
It is being assumed here that something exists. But it is impossible to demonstrate this, thanks to the unfalsifiability of solipsism. Of course, solipsism requires the existence of experience, but the existence of this is undemonstrable.
For a strictly scientific view, therefore, the existence of mental and corporeal phenomena is an assumption. Yes, I know this might seem like a pointless philosophical splitting of hairs. But it is crucial. The moment we say that the objects of the everyday world are truly real we have dismissed all worldviews for which they are not, and thus prejudged the issue.
In Three Roads to Quantum Gravity
Lee Smolin writes this.
"When we imagine we are seeing into an infinite three-dimensional space, we are falling for a fallacy in which we substitute what we actually see for an intellectual construct. This is not only a mystical vision, it is wrong."
From the logical proofs given by the second century Buddhist sage Nagarjuna, and by Francis Bradley, Hegel, and Kant (in my interpretation), and others, we see that this vision of an infinite three-dimensional space would not only be fallacious and wrong, it would also be the opposite of a mystical one.
If one respectable scientific view is that extended space and time are a wrong-headed vision, then this puts a differerent complexion on the question about Nothing.
