Tidbits (stars for the top two ideas):
*
-* "Or, more accurately but less evocatively, “find gravity inside quantum mechanics.” Rather than starting with some essentially classical view of gravity and “quantizing” it, we might imagine starting with a quantum view of reality from the start, and find the ordinary three-dimensional space in which we live somehow emerging from quantum information."
- "If we perturb the state a little bit, how does the emergent geometry change? (Answer: space curves in response to emergent mass/energy, in a way reminiscent of Einstein’s equation in general relativity.)
It’s that last bit that is most exciting, but also most speculative."
- "But the devil is in the details, and there’s a long way to go before we can declare victory."
- "In some sense, we’re making this proposal a bit more specific, by giving a formula for distance as a function of entanglement. "
- "We’re quick to admit that what we’ve done here is extremely preliminary and conjectural. We don’t have a full theory of anything, and even what we do have involves a great deal of speculating and not yet enough rigorous calculating."
*
-* "Perhaps the most interesting and provocative feature of what we’ve done is that we start from an assumption that the degrees of freedom corresponding to any particular region of space are described by a finite-dimensional Hilbert space."
- "A finite-dimensional Hilbert space describes a very different world indeed. In many ways, it’s a much simpler world — one that should be easier to understand. We shall see"
My 1 cent:
I don't know enough about this subject but...it's this creative thinking that is desperately needed in the sciences. I'm not trying to tear down others but instead just say that this is what happens when education advances. When enough (abstract) people focus on a subject, we will find a breakthrough.
