Redshift over cosmic scales: Anyone here know if it makes events appear to last longer? For example, if we measure an event to last exactly one second in our galaxy, would an observer 13 billion light years away also measure it to last one second? Seems like if the light 'stretches' from blue to red then the 'total length' of the light waves that are observed would need to increase too, right? Since the length of the wave increases, it would take longer to pass through the far-away detector, which would appear as a longer event.

Anyone know, and if there are any megabrains here, do you know by how much the time of the event would increase by? Since we're talking nanometers of shift from blue wavelength to red, it seems like it would be a very small increase, right?
