This question is with regard to Miller's planet, where 1 hour is equivalent to 7 earth hours. Dr. Brand and Cooper are present on the surface of the planet, whereas Romilly is on the Endeavour.
From what I have read, if Romilly wanted to look at the planet with a telescope, he would first need to overcome certain problems. First, by virtue of red-shift, the visible light would be shifted into the infrared region. Additionally, the light may appear distorted.
But, if Romilly were to overcome these problems, he would be able to see the events on Miller's planet in extreme slow motion.
However, my question has to do with video footage.
If (hypothetically) video footage were to be transmitted from Miller's planet in real time, would Romilly still see the events in slow-mo (as with the telescope) or in real time? If Romilly were capable of seeing the video footage in real time, he would be able to see the future!
Please, while answering this question, ignore the practicality of this and assume that video footage is successfully transmitted to Romilly on the Endeavour.
