What then,
What now,What next? Time
is, in many ways, a fabrication of our minds, a superficial construct
that helps us explain the universe, plot our course through existence
and show up when we're supposed to. Albert Einstein once said. "The
only reason for time is so that everything doesn't happen at once."
One thing happens, then another happens, this phenomenon is called "cause-and-effect". It's a notion so deeply ingrained that it's hard to think about things any other way. The concept of “reverse causation,” a fantastic notion suggests effect can precede cause, and the future can influence the past, assuming the past and future actually “exist” in the first place. There isn't kind of consensus in this state of thinking. The whole subject seems just too speculative to deal with either theoretically or experimentally. While reverse causation or retro-causation may sound like science fiction, it is firmly grounded in classical laws of physics. These laws say time is symmetrical, that it moves or should be able to move in all directions with equal ease. Developed equations explain how electricity and magnetism work in tandem. Electromagnetic energy, such as light and radio, travel in waves through empty space at the speed of light. But what about the direction of time? It's irrelevant whether electromagnetic waves arrive after or before they are transmitted. The waves are indifferent to the distinction between past and future.” |
