How to image a #wavefunction?

Fundamental particles, such as electrons, cannot be pinned down to one single location. Instead, a particle is described by its “wavefunction” – but imaging the wavefunction is a major challenge. Researchers @ our Uni managed to image the 3D wavefunction of a nanometer-sized organic molecule by combining state-of-the-art photoelectron spectroscopy with powerful mathematical algorithms: https://www.uni-goettingen.de/en/3240.html?id=8252

A #cosmic shape could explain the fundamental nature of the #universe

#Physicists have created a 3D shape called the #cosmohedron, which can be used to reconstruct the #quantum #wavefunction of the universe - and potentially do away with the idea of space-time as the underlying fabric of the universe

#Consciousness & #WaveFunction

#SabineHossenfelder: "The reason that [Sir Roger] #Penrose thinks that the collapse of the wave function creates consciousness is that he believes consciousness can't be computed. And since we know everything besides the collapse of the wave function is computable in #physics, the collapse must be it."

additional information : Additional insight on Carlo Rovelli's take: He views the wave function not as an independent physical reality but as a tool for calculating probabilities of interactions. Unlike the Many-Worlds Interpretation, Rovelli argues that the wave function lacks "ontological weight" and should be seen as a practical device rather than a fundamental entity. This perspective simplifies quantum mechanics, focusing on interactions rather than abstract complexities. #QuantumMechanics #Rovelli #WaveFunction
