Choose your reality. Literally. [Quantum mechanics vs. Materialism 1-0]
Reality doesn’t exist until it’s measured, at least for very small things, new research has found. By replicating a famous experiment where an object is given a choice for how to behave, physicists found that the object doesn’t actually make its decision until it is seen. The finding proves one of the central parts of…

Negative mass. Impossibilities. Dasein.
Matter with negative mass, a seeming impossibility, could actually have existed in the early universe, a new study shows. A novel solution to Einstein’s equations for gravity permits the existence of negative mass in a rapidly expanding universe like our own, physicists Manu Paranjape and Saoussen Mbarek of the University of Montreal report November 14…

Imaginary particles. Explaining tangible things...
Tangible products—like a solar-powered hearing aid—may come from not-so-real particles. More particular, scientists analyze the behaviour of modern materials with the help of imaginary structures called quasiparticles. (1) In physics, quasiparticles and collective excitations (which are closely related) are emergent phenomena that occur when a microscopically complicated system such as a solid behaves as if…

Higgs boson, lack of imagination, modern science.
The Higgs boson — a particle thought to explain how other particles get their mass — is tiny, but it may not be the tiniest particle yet. Theories have long predicted the existence of even smaller particles that might make up the Higgs, and recent research suggests these pip-squeaks, dubbed techni-quarks, are likely lurking in…

Physics constants not so constant. Unless you assume so...
Australian astronomers have combined all observations of supernovae ever made to determine that the strength of gravity has remained unchanged over the last nine billion years. (1) But is this really the case? How solid is such a conclusion? Digging a little deeper makes things more clear... The original paper can be found here. The…
