More and more scientists are turning to the idea of retrocausality to help explain amazing occurences in the world of quantum mechanics.
We’ve all heard of the “consequences of our actions,” where something in our past somehow brings about something in our future. Another common way to look at it is through the eyes of sowing seeds. You reap what you sow. However, some scientists think that it could also work the other way, through something they call retrocausality, which means your actions in the future somehow influence the past.
It seems a little crazy, and maybe even a little outside the box, to think that we could somehow influence our past by what we do in the future. However, many scientists out there are starting to focus more heavily on this idea of retrocausality and what it means.
Some of the big differences we see between the quantum realm and our own is how quantum objects can often become synced up in what scientists call quantum entanglement. Despite being light-years apart, these objects appear to act on the same timeline. This quantum entanglement throws many of our assumptions about the universe into loops.
For many scientists, understanding this phenomenon requires us to “kill” one of our most treasured physics ideals. For some, that ideal is locality, which says objects shouldn’t be able to interact at great distances which a mediator. Others want to kill the idea of “realism.” For Wharton and others, though, retrocausality seems to be the answer that holds it all together.
