I'm not convinced that this would disprove free will. Perhaps our choices are one of the things that operate retrocausally.

We metaphysically decide on some course of action, and that retrocauses back to the physics of our brains.

That seems about as plausible to me as the "what you think and feel inside your head is just an improvable illusion" theory.

A few years from now I already made my reservations at Douglas Adam's Restaurant at the End of the Universe


My BS meter and sniff tester are burnt out.

SiggeLund - you should read "Thrice Upon A Time" by James P. Hogan--It's about exactly what you describe, sending messages back to yourself.


Does anyone else read the Wheel of Time fantasy series, where time just keeps repeating itself over such a long period of time, that no one really notices?


lets see you predict who's going to win the cricket world cup


Dude, I saw the headline and my BS meter started screeching like a frickin' fire alarm


Smart Ass. I wonder if Gene Roddenberry is glowing with the same air of "I got it first (publicly)". Do you think the writer of Planet of the Apes will turn in his metaphorical grave, when the earth is run by apes and humans are but their slaves? How would Jules Verne describe his feelings when finding that most of his fiction has become truth?

However, I dissect your statement to pick the points I like and the ID statement concerning humans has a very good ring to it, even though I have already seen it in Douglas Adams second Dirk Gently book (I think), where a guy has a kind of time gate going back to beginning and dying there is the initiation point of evolution (again)...

Being a smart ass myself I have to say that the evolutionary process will never fully end until the host (i.e. the earth) ceases to exist. As scientist regularly are trying to point out, we are NOT the pinnacle of evolution, we are not the termination rule of a random process!


Although your post was titled "Retrocausality", I read "Retrocasuality". I was anticipating a hilarious post about old, outdated clothing, music preferences, hairstyles, etc. What a bummer when I read the actual post. Oh, well. It's Monday. I should have know it was too good to be true.


Okay, I'm a little late, but I have to (no free will you know) chime in on this one.

As far as anyone proving intelligent design, I must refer to the Master... Douglas Adams:

The argument goes something like this: "I refuse to prove that I exist," says God, "for proof denies faith, and without faith I am nothing."
"But," says Man, "the Babel fish is a dead giveaway isn't it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don't. QED"
"Oh dear," says God, "I hadn't thought of that," and promptly vanishes in a puff of logic.
-- Douglas Adams, The Hitch Hiker's Guide to the Galaxy (book one of the Hitch Hiker's Guide to the Galaxy series), p. 50

Of course this would only apply to the Biblical God. Any other God's waiting in the que still have a perfect right to lead their non-free willed ethereal existences.


This experiment has the same problem as a lot of physics experiments, and theories. It equates human knowledge with physical reality.


Oh damn ... i think i'm spooky too cuz i too have the same kinda theory though i never voiced it fearing fatal injuries. But since u've managed to survive so far, may be i too shud write about what i feel...


Sounds to me like the world is ready for a Dilbert Future 2: The Donut Theory written by Scott "Spooky" Adams.

The experiment doesn't prove retrocausality AND the non-existence of Free Will, it proves that at least on of the following is wrong:
1) Causality is only forwards in time
2) We have free will.

Off course, both might be wrong, but the experiment only proves that one of them are.
^C = ^A + ^B
(In English: If A is true and B is true, then C is true. However, C isn't true, so A or B or both must be untrue too.)


I think if I went back in time (or forward, however you want to look at it), I wouldn't have invented people. They're too complicated and messy. I can imagine coming up with fire or something, though. Fire rocks.

Mike B

Dating back to Newton's laws of motion, the equations of physics are generally "time symmetric" -- they work as well for processes running backward through time as forward.

This doesn't mean that in real life a process CAN run backwards as well as forwards, it's just that the maths equations don't care. The maths isn't real, it is just a way for humans to describe the world. In any physical sense it is impossible for me to have -1 apple, but negative numbers are a concept that is fundamental to maths.

I don't know whether Scott Adams is deliberately winding us all up or is illustrating the problems of a clever man with an inadequate education.


Too cool.

The article is two months old though, any updates on the progress for these guys?

But the thought of this is shocking. If the pattern can be determined a few microsecs before actually occurring, it is easy to imagine the nerds extending the period to an hour. And then sending a bitstream through... What could be done if some people were able to send themselves a warning an hour earlier? Now THAT'S a cool cellphone application. This freaks me out.

Proof of retrocausality would not be proof of intelligent design by humans. It would only show that it is possible, not that it happened. If they show that retrocausality is possible we will probably find that the universe has included some fine print to make sure nobody actually does anything like create themselves.

I won't be impressed until they can un-ring a bell.

Kevin Kunreuther

You sound like a twenty-first century Immanuel Velikovsky: you attribute to yourself other people's heavy lifting, dress it up in surrealist situations, bow for the applause and applesauce equally and rake it in. Hats off, gentlemen, hats off.


Do you know what this means? Assuming the experiment is a success you could hook the Wave/Particle detector at the end of the 6 mile long fibre optic cable to the binary output of a CPU. Hook the other sensor for the entangled proton to a binary input of the same CPU. Now you can send data and receive it before you send it. You’ve just created a faster than light CPU … I think I will call it a Retrocausium CPU. If you can receive data before you send it you can create a loop that will process data backwards. The more data and bigger the problem the further back in time it will finish. It could solve global warming using a mathematical weather model of the earth in -10 seconds. It could analyse all the data from all radio telescopes and find intelligent life on other planets in -1 minute. It could analyse the human genome and cure all known diseases in -1 hour. The possibilities are endless … it could revolutionise the computer industry ... but I should get back to binding more project files from 1997 my boss is watching.

We may circle around to where we started, in a way. There is a tribe of monkeys starting to use spears to hunt with. Starting the evolutionary process all over again being as you monkeys got it wrong.

I hope they get it right next time being as you idiots screwed up your brains so much and are destroying yourselves. Make sure you leave well documented history's of all your fuck ups with your stupid religions and maybe they will.

The TRUE donut theory -

And Iran is NOT acting like a democracy, USA has STOPPED acting like one. God! These Americans!!


Are you a messiah and/or may we start a religion that celebrates Adamsism?
