  • New experiments with vibrating drums push the boundaries of quantum mechanics.
  • Two teams of physicists create quantum entanglement in larger systems.
  • Critics question whether the study gets around the famous Heisenberg uncertainty principle.

  • The Dutch physicist Erik Verlinde's hypothesis describes gravity as an "emergent" force not fundamental.
  • The scientist thinks his ideas describe the universe better than existing models, without resorting to "dark matter".
  • While some question his previous papers, Verlinde is reworking his ideas as a full-fledged theory.

A New Hypothesis Suggests That Parallel Universes Might Interact after All

A new conception of quantum mechanics rests on the idea that parallel universes exist, and that they interact with our own to create weird and wonderful quantum phenomena. 


Quantum mechanics is hard to do. The great physicist Richard Feynman once remarked “It is safe to say that nobody understands quantum mechanics” and that statement was regarded as correct. The problem isn’t in the math, even an undergraduate can use Schrödinger’s equation, it is in what the math means.

Scientists Discover The "Angel Particle" That Is Both Matter and Anti-Matter

Researchers succeed in an 80-year-old quest to find the elusive "angel particle".

A team of scientists found first evidence for the existence of a Majorana fermion, a hypothetical particle proposed 80 years ago that is its own antiparticle.

The life and death of Schrodinger's cat, and what it really means

Schrodinger's cat is one of the most famous thought experiments of all time, but what does it mean for science, and what happens to the poor cat?

If you feel the need to put this cat in a box, you might be a physicist.
