Good morning everybody! Thanks for your interesting article. Nevertheless, as far as I remember, quantum entanglement experiments show that the effect is instantaneous. If causality travels 4 times the speed of light, it is still a bounded speed. I will review the experiments and check if they demonstrate that quantum entanglement is instantaneous or they only show that it happens faster than the speed of light.
Good point! I checked some experiments on Quantum Entanglement (QE) and found a few things. First, the max we have been able to observe QE is around 1200kms. But here is a more interesting discovery - though mostly QE is said to be instantaneous, there has been an experiment done by some Chinese physicists at a distance of 15.3kms and they found the QE to propagate at speed of 3trillion m/s, which is 10^4 times the speed of light - https://futurism.com/chinese-physicists-measure-speed-of-quantum-entanglement-2
Not sure what conclusion to make out of this, but a good experiment to refer nonetheless.
Thanks a lot for the reference! I just read it and the experiment proves that quantum entanglement’s speed is AT LEAST ten thousand times greater than the speed of light! That would be much faster than 4 times. Wonder where is the origin of the discrepancy. Your reference point me to the original experimental report: https://arxiv.org/abs/1303.0614 Have a great day and congratulations for your Substack!
Yes, things aren't matching up, for now. We'll be diving deep into it. David, If you don't mind me asking, are you a physics hobbyist like me too? :) feel free to not answer my question...just curious!

No problem 😉! I am a physicist by career, but these amazing subjects are not my speciality, and therefore here I am a hobbyist as well! 😃
