If state refers to the entire system, then the state of that system necessarily needs to change in a non-local way when one of the particles is measured. That is, the probabilities for the other particle change because of the measurement of its partner, and that happens in a non-local way...
Bell's inequality theory clearly shows this interpretation cannot be correct. The measurement of a particle must necessarily influence the state of the partner particle. Equally prepared systems on their own without non-local correlation cannot explain the violation of Bell's inequality. This is...
This is not the forum discuss this, but your statements about the origin of life show that you base your science on your beliefs, not on scientific facts.
There are plenty of scientific paper that describe successful experiments that cover different parts of a possible path from inorganic...
I wouldn't treat C# in one breath with C and C++. C# is a higher structured language based on and inspired by Java. Just like Java, it is compiled to byte-code which then runs on a virtual machine (which nowadays uses advanced JIT compiler techniques to speed up the execution). It is not in the...
I don't want to be harsh on you, but this is exactly the kind of thing that we are trying to avoid. If "data types" are mentioned, and you can only think of numbers and strings, then you may have learned a programming language, but have not learned software design.
The most striking...
Among the academic community, particularly in STEM, it is prototyping that is mostly needed, not serious programming. For that purpose Python is a good choice. But the academic community is an extremely small sample of all programmers.
To the general question: "what programming language should...
I can fully support this. As a first programming language, I would always recommend Java. It makes you learn about structured code, forces object oriented thinking, separation of concerns, and keeping track of type-checking, without the added complexities of C++.
Python is great for prototyping...
What I am definitely confused by, is the habit of changing coordinate system if they don't suit your needs. In my mind, coordinates are related to measurements, and you can only (and must) change a coordinate system, if it does not correspond to the measurements you are making.
I can fully...
Yes, I see it myself now. It is ## (1 - \frac{r_s}{r}) c## in the radial direction, correct?
I would have thought that it would be more practical to always use a coordinate system where the coordinate speed of light is c everywhere. But I guess in such a system it is not possible to describe...
The earlier question was about light pulses that are sent from an outside observer, reflect back from the object falling towards the black hole, and then return back at the observer again. They apparently would take longer and longer time to return back, the closer the object comes to the event...
Quick question then (about post #57 of https://www.physicsforums.com/threads/where-is-the-matter-in-a-black-hole.836527/)
You talk about bouncing light signals off the object that is falling into the black hole, and measuring how much time it takes for those signals to return, in order to find...
Thanks, I did not expect such an insightful answer to my philosophical daydreams 🤔
Are there physical situations where it is not possible at all to assign any coordinate system that reflects the measurements? That is, where it is not possible to define a coordinate system where spacetime...
