A somewhat rambling essay attempts to convince us that that is so:
It is true that many events in the Universe can be put into sequential order – but time is not always segmented neatly into the past, the present and the future. Some physical equations work in either direction.
A few theoretical physicists, such as the best-selling writer and physicist Carlo Rovelli take it even further, speculating that time neither flows, nor even exists. It is an illusion.
Of course, although some physicists propose that time does not exist, time perception – our sense of time – does. This is why the evidence from physics is at odds with how life feels. Our shared idea of what the concept of “future” or “past” mean may not apply to everything everywhere in the Universe, but it does reflect the reality of our lives here on Earth.
Like the Newtonian idea of absolute time, however, our belief in how time works for humans can also be misleading. And there may be a better approach.Claudia Hammond, “What we get wrong about time” at BBC
If time were really all in our heads, we would never miss planes. Good thing modern cosmology does not need to be serious.
Some fun with time:
Would backwards time travel unravel spacetime?
Economist: Can time go backwards?
Astrobiologist: Why time travel can’t really work
Carlo Rovelli: Future time travel only a technological problem, not a scientific one. Rovelli: A starship could wait [near a black hole ] for half an hour and then move away from the black hole, and find itself millennia in the future.
Rob Sheldon’s thoughts on physicists’ “warped” view of time An attempt to force complete symmetry on a universe that does ot want to be completely symmetrical
At the BBC: Still working on that ol’ time machine… BBC: “But using wormholes for time travel won’t be straightforward.” Indeed not. Unless everything is absolutely determined, some wise person from the future has already gone back through a wormhole and altered the present so that we can’t go anywhere.
