Posted By: Andrew Palfreyman"Weak measurements" in QM work something like an integrating detector, and Heisenberg can be broken with sufficient time.
Posted By: AngusI think I was the one who said that so you must be having a violent agreement with me. I'm not sure how Andrew feels about it.

Suppose this is the case: we're inside a simulation designed by a freckle-faced superkid for extra credit in her fifth grade science class. Is this something we could discover, or must it, like so many aspects of Theory 2, be forever hidden from our scientific investigation? Surprisingly, this variety of Theory 1 is quite amenable to experiment: neither revelation nor faith is required. What would we expect to see if we inhabited a simulation? Well, there would probably be a discrete time step and granularity in position fixed by the time and position resolution of the simulation—check, and check: the Planck time and distance appear to behave this way in our universe. There would probably be an absolute speed limit to constrain the extent we could directly explore and impose a locality constraint on propagating updates throughout the simulation—check: speed of light. There would be a limit on the extent of the universe we could observe—check: the Hubble radius is an absolute horizon we cannot penetrate, and the last scattering surface of the cosmic background radiation limits electromagnetic observation to a still smaller radius. There would be a limit on the accuracy of physical measurements due to the finite precision of the computation in the simulation—check: Heisenberg uncertainty principle—and, as in games, randomness would be used as a fudge when precision limits were hit—check: quantum mechanics.

It's interesting that the information content of a black hole event horizon happens to be the same as its surface area measured in square Planck distances. Who knows what that means?
Posted By: AngusUncertainty of energy at that scale must imply a length much smaller than Planck's?That is a really good point, profound in fact. How big is nothing? It must be very tiny indeed.

Not everyone has been here forever. Are you the same Anus in the politeness thread?

That the universe is a two dimensional hologram ... a book with 10^500 pages?
Posted By: AngusThat's a vast return of speculation for a tiny investment of fact. As well as being metaphorical to the point of incomprehensibility.
designed by a freckle-faced superkid for extra credit in her fifth grade science classI usually express this as "designed by a pimply video-game-playing teenager from the 15th dimension". Rather like my son, in fact.
