Quantum Entanglement: has there really been an unambiguous experimental basis?- troubled non-physicist

I been having bad dreams (a little exaggeration) on trying to contemplate if the arguments stated in EPR paper may have been correct. It is not clear to me whether Bell really did disprove the hidden variables theory. Is the reality of Quantum Entanglement ...

Two White Dwarf Stars And A Superdense Pulsar May Challenge The Strong Equivalence Principle

A newly discovered system of two white dwarf stars and a superdense pulsar, all packed into a space smaller than the Earth's orbit around the sun, could allow astronomers to tackle the very nature of gravity itself. The pulsar is 4,200 light-years fr ...
