🌏🇪🇺 🇭🇷 Constantly morphing; time is irreducible. It is not space-time, it is time...space. U(1) & △ is enough.








A company claims to have developed a microchip that can extract "unlimited power" from the vacuum. I've had a look youtube.com/watch?v=sEteCJ…










I am allergic to this! No, this does not mean “negative time officially exists,” time travel was observed, or causality failed. What was measured is a negative group delay / negative weak-value dwell time for photons transmitted through a rubidium atom cloud. That is a signed quantum/statistical quantity obtained from weak measurements over many trials, not a stopwatch reading showing a photon literally leaving before it entered. The University of Toronto group itself says the experiment does not claim photons travel backward in time or that time machines are possible; it is about the long-known phenomenon of negative group delay. The actual paper reports that the measured atomic excitation-time signal is proportional to the photon’s group delay, which can be negative near resonance. (cqiqc.physics.utoronto.ca) So the accurate headline is: “Physicists measured a negative weak-value/group-delay effect in light–matter interaction.” Not: “Cause and effect broke.” Not: “Photons exited before entering.” Not: “Negative time exists.”




This is eye-opening. A fast food job in the US pays significantly more than AI developer jobs in France or Germany, which have higher salaries than most other European countries. Europeans simply don’t notice how poor they become compared to others. Choices have consequences.
