My thought is you are the second ATSer to cite that Einstein
quote in your OP apparently without understanding the meaning. Einstein's theory does constrain causality which is usually represented by light cones
in space-time diagrams. Within these light cones the sequence of events can vary depending on the reference frame of the observer, which is what
Einstein's quote refers to. This is discussed at the following source:
Relativity Theory and Causality
Among the many interesting consequences of the Special Theory of Relativity (see the exercises) one is that nothing that carries energy and
momentum can travel any faster than light does in the vacuum. This immediately sets a limit on causality and it clearly requires us to be very careful
when we talk about simultaneous events.
The restriction on causality is set because the only way that a "cause" at location x = 0 and time t =0 can be responsible for an "effect" at
location x = L and time t is that c t > L, where c is the speed of light in vacuum. So, two events that are separated in space far enough can have no
causal connection. (Some people prefer to refer to this consequence as the breakdown of locality; i.e. two events that are far enough in space may be
causally connected, but are non-local. But so long as we understand what is that we mean, the rest is terminology). Similarly, two events can be
regarded as simultaneous, or not, depending on their space-time locations! In fact, different observer may view the "same two events" in a different
order in time.
In a similar consideration, this theory now allows us to check causality (or rather the lack of it) by separating events in space such that the light
from one cannot reach the other within the time period of their occurrences. This is in fact how Einstein's theory of relativity relates to quantum
So, please don't pretend Einstein's quote endorses retro causality, because it doesn't. It's an acknowledgement of simultaneity
issues from different frames of reference.

Above is my more complicated response. My simpler one word response is that it looks like
n.(or adj), the way a person is when they uncritically believe unsubstantiated or unfounded ideas. Short for "woo woo".(See Russell's
definition of woo woo)
Shirley believes that in a past life she was the Jolly Green Giant of Rainbowland. Shirley is very woo.
However this doesn't stop scientists from publishing papers on this topic, as discussed at this link:
Bem's Psi Research
This is an involved topic and that link is long, but in short, scientists are very skeptical of these claims and they have many reasons to be
To Daryl Bem's credit, his paper states that his results should not be accepted by the scientific community until they have been successfully
replicated. To my knowledge this has not occurred, though I haven't seen Bem's follow-up paper, which may not have been published yet (if he
publishes a follow-up at all).
