When I was answering some older Interstellar related question, I had to re-watch some parts of Interstellar. I've noticed one thing about wormhole and data they were able to send (back) through it.
At the beginning, when Cooper with Murph reached the NASA station and Brand, Doyle and Romilli are explaining them the mission details, Doyle said
Data transmission back through the wormhole is rudimentary, simple binary pings on annual basis give us some clue about which world has the potencial ...
Which means ships sent to the wormhole had enough power to send binary data back through the wormhole.
Signal from the Earth got through the wormhole to the endurance quite well, since Cooper had 23 years worth of messages.
If I would send some space ships through the wormhole, I would probably try to equip these ships with as good transmitter as possible and state strict protocols for communication.
My question is (according to be able to send binary data back through the wormhole) why they didn't use some protocols for more complex communication - e.g. being able to send data from sensors, images - possibly encoded using base 64 to binary data and send back through the wormhole.
Maybe it would help spotting giant waves on Miller's planet, or getting true data from Dr. Manns sensors - so he would not be able to fake them.
And if they just could not send such complex data, may anybody explain why ?
