Determinism

Free will doesn't exist. It's all just a bunch of physics rules.

What happens when you mix red and blue paint? You get purple. What happens when you put mentos in coke? It fizzes. If you put two magnets next to each other with similar polarities, they will repel. These are just things that happen automatically. They do not "choose" to happen.

Human personalities and thoughts are just more complicated versions of that. We do things based on our previous experiences. Our personalities and decision-making processes are just complicated algorithms. It's like a more complicated version of Conway's Game of Life. We have no say in the matter.

If you knew the position of every particle in the universe, you could know the future, because we are all just interacting in linear ways.

People cite dumb shit like the uncertainty principle, as if not knowing the position or speed of something means none of this is true. Other people cite pseudoscientific metaphysics bullshit. But at the end of the day, 2+2 does not choose to be 4. It just is. Similarly, Everything we do is already determined based on the interactions of particles in us and around us.

Quantum Experiment Confirms Causality Is Fuzzy (physicsworld.com) 109

"An experiment has confirmed that quantum mechanics allows events to occur with no definite causal order," reports an article shared by long-time Slashdot readers UpnAtom and jd. Researchers at the University of Queensland in Australia believe this could link Einstein's general theory of relativity to quantum mechanics, according to Physics World:
In classical physics -- and everyday life -- there is a strict causal relationship between consecutive events. If a second event (B) happens after a first event (A), for example, then B cannot affect the outcome of A. This relationship, however, breaks down in quantum mechanics because the temporal spread of a particles's wave function can be greater than the separation in time between A and B. This means that the causal order of A and B cannot be always be distinguished by a quantum particle such as a photon.

In their experiment, Romero, Costa and colleagues created a "quantum switch", in which photons can take two paths. One path involves being subjected to operation A before operation B, while in the other path B occurs before A. The order in which the operations are performed is determined by the initial polarization of the photon as it enters the switch.... The team did the experiment using several different types of operation for A and B and in all cases they found that the measured polarization of the output photons was consistent with their being no definite causal order between when A and B was applied. Indeed, the measurements backed indefinite causal order to a whopping statistical significance of 18 -- well beyond the 5 threshold that is considered a discovery in physics.

Science Magazine applauds the experiments for "obliterating our common sense notion of before and after and, potentially, muddying the concept of causality.
