fascinating!

I heard about three years ago that a scientist playing around with sub atomic particles had done this ...

he hooked up a 'frequency modulator' (similar concept to FM radio) to a particle stream
at the other end he had a receiver, connected to a tape recorder

... he played music from a local radio station in one end and recorded it at the other end ...

... except he kept recording the end of the PREVIOUS track
(presumably before he had pressed the record button)

On the scale of fundamental particles, time dimension is symmetric, that is there is no distinction between past and future.

But on the scale of statistical systems such as organisms, buildings, humans, economy etc, time seems to be asymmetric; the past affects the future but not vice versa.

The so called 2nd law of thermodynamics and entropy give rise to the directionality of time on the macro scale. This difference between the micro and macro scales regarding time is a paradox of course which did not find a sufficient resolution as yet.

Perhaps time does not exist at all?

From a view point of human consciousness, if every mistakes will be correctable, no people will educate themselves and they even won't try not to reproduce the same mistakes. Also, if this becomes possible, sports competitions like Olympics will be fairly boring, since its wonderfulness is acquirable in that performances is by no means reproducible. Of course nothing is better than to have less mistakes, but I'd like to say that to regard every mistakes should be denied isn't admirable.

If such a thing is really possible.
