Nonlocal correlations that define quantum entanglement could be reconciled with Einstein’s theory of relativity if space–time had two temporal dimensions. That is the implication of new theoretical ...

The James Webb Space Telescope has revealed a rare "Einstein ring," revealing two distant galaxies in an optical illusion ...

Machine learning helped show how harnessing the weird effects of Einstein’s special relativity could enable a new kind of quantum computer – and it could also lead to new insights into the quantum rea ...
