Dance of 3 stars confirms Einstein’s ‘most fortunate thought’

Researchers in Europe have now confirmed the universality of free fall – which Einstein called his most fortunate thought – with extremely high precision. To do it, they spent 8 years tracking a triple star system containing a millisecond pulsar. Source: https://earthsky.org/space/pulsar-psr-j03371715-einstein-universality-of-free-fall…

Does relativity lie at the source of quantum exoticism?

Since its beginnings, quantum mechanics hasn’t ceased to amaze us with its peculiarity, so difficult to understand. Why does one particle seem to pass through two slits simultaneously? Why, instead of specific predictions, can we only talk about evolution of probabilities? According to theorists from universities in Warsaw and Oxford, the most important features of the quantum world may result from…
