A team of researchers from Germany, Italy and Hungary has tested a theory that suggests gravity is the force behind quantum collapse and has found no evidence to support it. In their paper published in the journal Nature ...
Quantum mechanics and the general theory of relativity form the bedrock of the current understanding of physics—yet the two theories don't seem to work together. Physical phenomena rely on relationship of motion between ...
