Then you'll have to do a degree in experimental physics!

The idea of a disk confuses the issue that within the disk you have particles being accelerated towards ##c##. Each of those particles has kinetic energy tending to infinity. It doesn't matter how complex your overall structure is, a particle with mass cannot be accelerated to ##c##. Note that...

That's a physical inevitability. Nevertheless, the kinetic energy of a spinning disk tends to infinity as the speed of rotation tends to some finite value - depending on the radius of the disk. It's not even theoretically possible to have part of the disk moving at ##c## from a calculation of...

Why not simply accelerate a particle at constant acceleration until it surpasses ##c##? That's what you are doing to a particle on the edge of your disk.

Theories can only be tested so far. It's an open question whether a cat could tunnel through a wall by sheer randomness. The probability is so low, that we can't hope to test it. The question is generally irrelevant to understanding QM. For example, you could become undefeated world chess...

Just to add that electron tunnelling is a specific phenomenon that is useful in microelectronics. But, everything about the macroscopic world is essentially determined by the probabilities of large numbers. Everything we learn about macroscopic processes is not strictly speaking fully determined...

If you've lost your cat, don't blame Quantum Mechanics.

Whether two 3D vectors are perpendicular depends on the frame of reference. Imagine a particle is moving along the x-axis and the force on the particle is in the y-direction. Now change to a frame of reference moving in the y-direction. The force vector still points along the new y'-axis, but...

In simple terms, if the set of natural numbers is finite, then there is a largest whole number. If not, then the set must be infinite (that is to say, not finite). More formally, the set is defined to be infinite by the Peano axioms. And, within set theory, there is the axiom of infinity...

Can you state the uncertainty principle?

A better analogy would be computer viruses. How successful are we in catching and prosecuting cyber criminals? I can't take seriously the idea that you are going to trap a rogue AI by offering it a bone and then looking at the tag round its neck to see who owns it. Even if you prosecute the...

I fear that the legal system moves (at least) an order of magnitude too slowly to be of much use in combatting AI. It takes years to tackle new things. And, AI will be a fast-moving target. In fact, AI could move faster than any previous development.
