Does the alayavijnana exist in the formless realms?

Does the alayavijnana exist in the formless realms? --------------------------------------------------- Presuably, if we are reborn there. But there is no matter in the formless realms, so my crazy hypothesis for how my mental stream can reoccur outside my body (action at a distance, of gravity) seems to be disproven if the title question is yes (the alayavijnana does not necessarily include form and mass undergoing the gravitational constant). For what it's worth, I would think that supposing there is no rebirth without physical mass, then that would suffice to demonstrate that the strangeness of action at a distance (seemingly involved in post-mortem rebirth) ***itself does not preclude* the possibility of rebirth**, though of course if the identity of mind with body means this this brain is necessary for my mind, then - my mind cannot live without this living brain Currently, I do not see any other motivation for the claim that death is the end of the citta-santana, but I welcome any correction to that.
