Ken G,
RE: "I'm not particularly wild about any variants of the AP, they all seem to represent, as someone once said, a puddle in the street wondering why it so miraculously fits to the shape of the pothole. Everything we know about the universe comes through the filter of our perception, so...
Ken G,
I can't disagree with that, it is the place where our models of reality, and our models of our place in reality, bump heads. Is there any concept of "reality" at all that does not require we insert a concept of a perceptive intelligence into it to interpret what we even mean by that...
Thanks Ken G. Its always a pleasure reading your posts.
Doesn't this all boil down to the question of whether an independent reality exists without the presence of a "consciousness"? It seems to me that has always been the real argument involved in the measurement problem.
If reality is...
actually saying a theory of quantum gravity must exist is a sort of straw-man argument. There is obviously some relation which can be described in some way, between qm and gravity. Perhaps gravity is emergent from qm, which would also conclude a relationship between the two.
I am just...
Tom,
"So all these approaches have not yet succeeded in defining a unique theory of quantum gravity. But saying that they have failed is absurd."
You know that science is in big trouble when it hides behind semantic nonsense to deny something we all know to be a fact. That being, the...
As far as i know they've all failed. If you know of one which is now proven and accepted then please do share that breaking news with the rest of us :-)
Its a well-known fact that various approaches to quantum gravity have failed thus far. Otherwise we would all have heard about it as a major breakthrough.
Some theory of quantum gravity must exist? Well that's your opinion. I don't agree.
yes of course. However, considering no-one appears able to integrate qm and gravity..the whole idea of quantum gravity is in itself speculative.
That didnt stop you bandying about the term as if its a fact :-)
My question was simple. Have we been able to measure/sense gravitaitonal effect within a un-decohered quantum state.
But its okay becaus ei found another paper by some guys claming gravity is a macroscopic emergent property from quantum information, so i guess they are arguing gravity does...
redshift doesn't prove gravity at quantum scale. You are talking light which is being measured hence its no longer in coherent state. I am talking about proof of gravity within an undisturbed quantum state.
I was just wondering because it seems there is a contradiction in qm. If a quantum state can only be represented by an abstract statistic then would not gravity be equally subjective until decoherence occurs?
And what about entanglement? It appears to act as a constant (an immediate one)...
Well *if* their brains are quantum mechanical then their ability to predict probabilities and make a choice of outcome would in itself be a quantum mechanical function. Of course Dennett rejects there is anything quantum mechncial about the human brain, but it would be the irony of ironies :-)
