Time might not have a fixed direction in quantum systems, physicists show
In a nutshell Researchers have demonstrated mathematically that quantum systems preserve time-reversal symmetry, meaning ...
Physicists uncover evidence of two arrows of time emerging from the quantum realm
What if time is not as fixed as we thought? Imagine that instead of flowing in one direction—from past to future—time could flow forward or backwards due to processes taking place at the quantum level ...
