The concepts 'cause' and 'effect' are predicated on the concept 'change': an 'effect' is a change in the state of an object brought on by a 'cause'. The concept 'change' implies at least two non-identical states for the object in question. ∴ Unless a single object can exist in two places, or otherwise maintain two non-identical states, change can only occur ...

We can't scientifically determine causality's dependence on time until we can measure the smallest amount of time (if it exists). However, some quantum physicists believe quantum entangled particles interact instantaneously over large distances. Implying causality independent of time. According to some interpretations of quantum mechanics, the effect of ...

Well it may be true and seems logical or sensible and as a matter... Of course, science can not touch upon everything there is and isn't and this leaves open nearly an infinity of chances (possibly, literally, an infinity of infinities^i) that there is a distinct personality that exists outside of time and within this being's "mind" exists the "our" ...

I will interpret the question as suggested by Philip: whether an argument to this effect has been discussed in philosophy. It was. A philosophizing mathematician/computer scientist/physicist David Wolpert formalized just such an argument in Physical limits of inference. Wolpert formalizes measurement, observation of a phenomenon, memory of past information ...

Drop a rock in a hole through a planet with gravity and no lava and it would go to the middle and act like a yo yo until it finally stops. It would stay in the middle. Now being its suspended, either way then would be up if it was lifted from either end. The hole would be bottomless being its open on both ends of the planet.

Jimit, let me say first you have my condolences. Here I will provide another way to look at unlikely tragedies. In my previous career I had to deal with finding the root causes of catastrophes in our factories. Fortunately, none of these involved loss of life, but they had huge consequences for our business. What I discovered was that these disasters were ...

What's missing from the picture is entropy; the tendency toward greater entropy establishes an effective 'direction of time' that correlates with our perceived sense of time passing. We see eggs break rather than spontaneously forming from broken pieces. We can conceive of physical trajectories that would 'reform an egg' due to reversibility, but in ...

@conifold- Here is a Spinoza response to a question which tangentially resembles the one here. It concerns ideas which appear to have no reference in reality, in this case a series of rectangles which can be 'pictured' or imagined in the minds-eye' but which have no existence. Not sure I can make any realtime sense of this, any thoughts. Cheers, Charles M ...

The experiment would work in principle, but it would amount to create a superposition of state of the observer+object system. If you don't include the observer, the state of the observed system considered separately will decohere because of the many degrees of freedom of the observer that gets entangled with it. After the observer has interacted with the ...
