Rob Sheldon unpacks the new “backwards causation”quantum mechanics research

QM is all about microstates and their measurement, but not about macroscopic properties that you and I normally associate with everyday objects–smoothness, ripeness, tools like “hammer and nail” or biology like “chicken and egg”. So indeed we can entangle QM microstates, but can’t entangle chickens and eggs, and therefore using those terms creates a semantic muddle.

Does time exist and do we experience it?

That’s a perhaps surprisingly contentious topic among theoretical physicists: You see, whether time flows forward, or doesn’t flow at all, or moves back and forth, our resulting subjective experience would be identical in all cases: we would always find ourselves in an experiential snapshot extending smoothly backwards in memory and forwards in expectation, just like Read More…

Is there a crisis inside the physics of time?

Did Carlo Rovelli, start a fashion for debunking time with The Order of Time? Here’s science writer Marcia Bartusiak, author of Dispatches from Planet 3, asking whether it is time to just get rid of time: You might say that quantum mechanics introduced a fuzziness into physics: You can pinpoint the precise position of a Read More…

Rob Sheldon’s thoughts on physicists’ “warped” view of time

Further to Carlo Rovelli’s views on time travel (only a technological problem, not a scientific one) and the order of time in general,  views, as set out in The Order of Time, our color commentator Rob Sheldon offers, — If I can speculate about what goes on in physicist’s heads, this issue about time is an attempt Read More…
