Frankly to you dkv!

Did you mean speed instead of "spread".

Any way we, right now, do not know if some distant Galaxy is sending light to us that is traveling on its way faster than the speed of light we measure in this locale. We do know that Einstein and about all academics contend that there is a limit to the speed of light and use the measure we make here as a likely limit.

You appear to be talking about something else as if the "information form" or their "nature" is a factor and you lost me there. Any way it is nice to hear from you again.
