David Gross, a 2004 Nobel Laureate in physics, predicted in his tribute to Einstein that spacetime is "doomed", that it is not fundamental. So a Nobel laureate agrees. Also Nima Arkani-Hamed agrees that spacetime isn't all there is.TexasScientist said:There is no consensus among our "best physicists" who state that. Name them. At best the concept of amplituhedrons is another way to describe quantum activity. This all comes from string theory, which is interesting but hasn't really told us anything of substance so far. This may be important in terms of improving perturbative quantum field theory calculations, but it is not a new theory of physics. It's a way to organize quantum field theoretic calculations in the unitarity method. It's interesting and may be important.Doc Holliday said:Also we know for a fact that amplituhedron and decorated permutations exist outside of spacetime and project perfectly down to space time.BusyTarpDuster2017 said:And for the umpteenth time, the math behind the quantum fluctuations must be constrained within limits. This constraint by necessity must exist OUTSIDE spacetime. Spacetime can not constrain the conditions of it's own origin, before it even existed. That's a circular logic failure.TexasScientist said:If spacetime are quantum variables, then spacetime can spontaneously arise with the particles, laws, and energy that make up the universe.Doc Holliday said:Quantum fluctuations do not create spacetime, they are spacetime. You can't point to spacetime/physicalism as causality to further spacetime/physicalism or you have a situation of infinite regress and a paradox of turtles all the way down.TexasScientist said:We know for a fact that quantum fluctuations exist. You don't have to understand every aspect to know this.Doc Holliday said:No.Quote:
There is no cause. Quantum fluctuations are spontaneous and random. This is well established. You absolutely no empirical evidence of any supernatural forces outside of our universe that have any interaction within our universe - only unfounded wishful thinking.
Quantum particles/behavior are still spacetime.
There's absolutely ZERO evidence the brain produces consciousness. There is no mathematical theory explaining the pattern of neural activity that creates consciousness. Science hasn't shown that the taste of chocolate is produced by xyz.
Also posit this: if you think your brain produces consciousness then your brain is hallucinating reality. How do you know what it's presenting to you is fundamental reality? How do you know it's showing you everything?
The fact that when your brain dies, ceases to function completely, or partially consciousness is impaired or ceases. You don't need a mathematical theory to completely explain all aspects to know this. Observation tells us this fact.
What you posit proves what I'm saying. Hallucinations can be chemically induced through action on various parts of the brain. Observation, and what we do understand through neuroscience tells us the brain processes and interprets and stores neurological information received. We test what it presents to us to see if it conforms with what we know to be true of reality. Impairment of the brain function can produce hallucinations, and alteration of personal behavior from what is normal. Do you really think the crackhead shouting gibberish on the street corner is really acting under the influence of god or some supernatural being? Or, do you think they just might have biochemically damaged their brain to the point that it is impaired from normal function. One should give some consideration to the thought that extreme religious indoctrinations, reinforced through time and culture similarly can damage or impair rational neurological processes.
Just because our brains alter consciousness does not mean the brain is where it's derived from. You have no mathematical theory explaining the pattern of neural activity that creates consciousness.
I don't need a mathematical theory to understand what observation confirms. Analogously, we don't have a mathematical theory that explains what gravity is, but we understand from observation and mathematics what it does. Saying god does it is intellectually deficient.
What it points to is the existence of something outside of spacetime, i.e. supernatural. It's funny how you're desperately promoting the idea of quantum fluctuations to get AWAY from the supernatural, when that is exactly what it's leading to.
It's literally an "object" outside of spacetime first discovered in 2013 that we don't fully understand yet. It's a monolith we're staring at. Our best physicists are telling us spacetime is doomed, as in it's not the end point of reality.

There is nothing about this concept that precludes a spontaneous universe.
You're going to have to prove that reductive materialism is all there is. That spacetime emerges from nothing. You also have to prove how spacetime teleologically caused abiogenesis and to what end/purpose. You'll need a theory of everything, which is impossible given godel's incompleteness theorems. You'll need to get around black holes/gravity. You also need a mathematical theory explaining the pattern of neural activity that creates consciousness.
Good luck, because what you have to do to prove up your faith in physicalism is impossible.
Also, are you a nihilist? You must certainly believe that any concept of human meaning is just a byproduct of brain chemicals and serves no real purpose.
