Everything can be broken down to a digital signal.

AI Thread Summary
The discussion centers around the concept of dividing lengths and the implications of the Planck length, which is 10^-33 centimeters and considered indivisible. It challenges the assumption that any length can be halved indefinitely, asserting that at the Planck length, locality is lost, leading to a binary state of existence—either present or absent. This raises the question of whether all matter can be considered digital, akin to a digital signal represented by 1s and 0s. However, it is argued that this perspective is flawed; the loss of locality suggests a state where something can be both present and absent simultaneously, similar to quantum qubits, which exist in a superposition of states. The discussion concludes that it is incorrect to categorize all matter as digital due to these complexities.

If we take a segment of length, we can divide it in half. We can take one of the remaining halves, and we can divide it in half again. We naturally assume that this can go on forever. We assume that no matter how small a length we end up dealing with, we can always - at least conceptually - divide any remainder in half. It turns out that this is not true. There is a length known as the Planck length, 10-33 centimeters, that is indivisible.

At that point is loses locality.. so its either there or not.. so to speak it becomes a 1 or a none if you will.

A digital signal is a 1 or a 0...

So is it completely wrong to say all matter is digital?

Of course it's wrong.

You're logic is like this scene from Monty Python.

There is a simple way to figure out if she is a witch or not.

Witches burn, and what else burns?

Wood!

Yes, and wood floats. What else floats?

... A duck?

Yes! So if this woman weighs as much as a duck, then she is a witch!

You are contradicting yourself. If something loses locality, it means that its position is spread out over that spatial location, meaning it is here AND there. So it isn't simply there or not there (1 or 0), but rather there AND not there (1 AND 0). This is similar to the quantum qubits, where in a bipartite system, you do not just have 1 or 0, but also a state of 1 AND 0.

So yes, it is completely wrong to say that all matter is digital.

Zz.
 
Fantastic, Evo! (you were in no position to retrieve that scene and yet you memorized the script exactly) and thanks for the link, Robert. Copying that link shamelessly for using it somewhere else.

10-33 centimeters ---divide that by Pi-----what do you get?
 
Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...
Thread 'My experience as a hostage'
I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
