Causality is one of those difficult scientific topics that can easily stray into the realm of philosophy. Sciences relationship with the concept started out simply enough: an event causes another event later in time. That had been the standard understanding of the scientific community up until quantum mechanics was introduced. Then, with the introduction of the famous spooky action at a distance that is a side effect of the concept of quantum entanglement, scientists began to question that simple interpretation of causality.
Now, researchers at the Université Libre de Bruxelles (ULB) and the University of Oxford have come up with a theory that further challenges that standard view of causality as a linear progress from cause to effect. In their new theoretical structure, cause and effect can sometimes take place in cycles, with the effect actually causing the cause.
The quantum realm itself as it is currently understood is inherently messy. There is no true understanding of things at that scale, which can be thought of better as a good set of mathematical probabilities rather than actualities. These probabilities do not exactly lend themselves well to the idea of a definite cause and effect interaction between events either....
If this isnt all confusing enough, there are some extremely difficult to conceive of implications of this model (and to be clear, from a macro level, it is just a model). One important facet is that this finding has little to no relevance to every day cause and effect. The causes and effects that would be cyclical in this framework are not local in spacetime, according to the press release from ULB, so they are unlikely to have any impact on day to day life.

You do good things without expecting something from it.

But who knows? Certainly not me. Fascinating stuff, though

(69,803 posts)but this quantum stuff....
it does pretty much make intuitive sense to me, as someone whose da taught stuff about physics while still knee high. fun shit.
tho i will say, fluid dynamics is a lot more practical, esp if you are a farmer.

(4,541 posts)People assume that time is a strict progression of cause to effect, but actually, from a nonlinear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly, timey-wimey... stuff. --The Doctor

(28,094 posts)Asked my hubs a few wks ago if time is nonlinear. He said it all depends on the curvature tensor but we don't know what it is. (I'm just a dodo, he's the physicist.)
