(Phys.org) —Is it possible that a moving object could have zero energy? The common sense answer is no, since motion itself is kinetic energy, but this answer has been challenged recently by the concept of quantum time crystals. ...
Astronomy experiments could soon test an idea developed by Albert Einstein almost exactly a century ago, scientists say.
