Penrose (2004: 603):
At least in this book, I shall refer to what is commonly called ‘quantum information’ as quanglement. The term suggests ‘quantum mechanics’ and it suggests ‘entanglement’. This is very appropriate. This is what quanglement is all about. Quanglement also does have something very much to do with information, but it is not information. There is no way to send an ordinary signal by means of quanglement alone. This much is made clear from the fact that past-directed channels of quanglement can be used just as well as future-directed channels. If quanglement were transmittable information, then it would be possible to send messages into the past, which it isn’t. …
As far as I can make out, quanglement links are always constrained by the light cones, just as are ordinary information links, but quanglement links have the novel feature that they can zig-zag backwards and forwards in time, so as to achieve an effective ‘spacelike propagation’. Since quanglement is not information, this does not allow actual signals to be sent faster than light.

From the perspective of Systemic Functional Linguistic Theory, time is the dimension along which processes unfold. In this view, processes extend in time, maximally from initial to final temporal locations. That is, time is endured, not moved through, whether backwards or forwards.
