From Barry Isaacs
We read that the vacuum of space may exist in an unstable state and could spontaneously decay into a lower energy state at any time (2 May, p 35). We are told that this decay would, if it occurs, radiate out from an initial point at the speed of light.
Is there any reason not to believe that this decay could have already occurred at some remote distance, and that the boundary between the two states is now racing towards us? If so, is there any way we could detect the approaching end of everything we understand as reality?
Might this explain the absence of time travellers from the future – in that there is not much future (as we know it) remaining?
