Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics. Physicists have shown that simulating ...

The quantum world operates by different rules than the classical one we buzz around in, allowing the fantastical to the bizarrely normal. Physicists have described using quantum entanglement to ...

Circuit diagrams for (a) standard and (b) PCTC-powered weak-value amplification. Time progresses in the laboratory’s rest frame as one proceeds upward along the central, vertical axis. Black lines ...
