Mutating Quantum Particles Set in Motion

​Density plots showing how two particles move through bosonic (“0”) and pseudo-fermionic (π) regions after being released next to each other in two different scenarios. Left: The particles start out as bosons and move together (solid lines) left and right before impinging on a 0-π; border, where they are partially reflected (solid lines) and partially split (dotted lines). For each splitting, one particle escapes the bosonic region. Right: Starting as pseudo-fermions, the particles move in a “superposition” of two ways: in one, they rapidly move apart as ordinary fermions and pass straight through the π-0 borders (dotted lines); in the other, they are bound together, move very slowly, and are forever trapped in the fermionic region (solid lines).

Scientists shed light on Mystery of Dark Matter

Scientists know dark matter exists because of its interaction via gravity with visible matter like stars and planets.

Scientists have identified a sub-atomic particle that could have formed the ‘dark matter’ in the Universe during the Big Bang. Nuclear physicists are putting forward a new candidate for dark matter – a particle they recently discovered called the d-star hexaquark.

Up to 80% of the Universe could be dark matter, but despite many decades of study, its physical origin has remained an enigma. While it cannot be seen directly, scientists know it exists because of its interaction via gravity with visible matter like stars and planets. Dark matter is composed of particles that do not absorb, reflect or emit light.

Now, nuclear physicists at the University of York are p...
