“It’s important to emphasize at this point in time, whatever that means, that retrocausality is not the same as time travel.”
The funny line there is at this point in time. The whole article is about how the future influences the past so… at some point in time retrocauslity will be the same thing?
- lupire 4y agoRetrocausality is like time being cooked spaghetti instead of dry. Or even macaroni. The world line is not "parallel" to the time line. Like the One Electon Universe idea ofositrons as time-reversed electrons. The article doesn't define time travel precisely, but presumably they mean discretely jumping ahead or back without passing through interventing moments.
