The second half is from... whatshis name... Sorry, i will never remember it but you can find it poking around.
He talks at length about things going back in time and changing results.

Like an experiment where a student, wearing earphones, listened to a tape.
There was left ear buzzs and right ear buzzs. And they were to count them.

Next they were told to think about getting more right ear buzzs.
(the tapes were recorded by a RNG machine without ever being heard before)
And lo and behold, there were more right ear buzzs.

So, the students thoughts affected the past.
