So if space would expand with 70kms/mpc and we would be able to observe an event 10mpc away, would two photons coming from the event separated at the event by 1 second arrive with a time separation of 1 + (10*70/c) on our location?
Asking this to see if I understand some of this expansion. I guess in reality you would be lucky if both photons arrive over such a fast distance and encounter so many different influences that this delay is not measurable.
