How does the watch work in Interstellar?

In the movie we see him pushing with his fingers on the world tube of the watch’s second hand. His pushes produce a backwards-in-time gravitational force, which makes the second-hand twitch in a Morse-encoded pattern that carries the quantum data.

What is the data transferred in Interstellar?

In Interstellar, they have shown that the astronauts Mann, Miller and Edmunds were sending signals to NASA (Earth) through their beacons. Also NASA is able to send videos recorded on earth to Cooper and his team while they are in all together a different galaxy!

How did Cooper and the robot transmit the information to Murphy?

In the process, Cooper and robot TARS jettison themselves to shed weight and propel Endurance to ensure it reaches Edmunds’ planet. Cooper manipulates the second hand of the wristwatch he gave Murphy, using Morse code to transmit the quantum data that TARS collected from inside the event horizon.

How Morse code is used in Interstellar?

You take your finger and tap the opening. You could feasibly communicate with someone via morse code by manipulating the air flow. Now, Cooper is given the tesseract, which allows him to reach between dimensions of time and space, which the future us have harnessed.

How does Cooper actually transmit information to his daughter?

There’s only one way to get the information required to make Plan A possible: Go into a black hole and record everything inside of the black hole and then transmit information from inside that black hole to your daughter using morse code on the minute hand of the watch you gave her during the movie’s neverending …

How did Cooper get NASA coordinates?

Anyhow, the point is to lure Cooper into the tesseract somehow, which is achieved by the subtle manipulation of gravity in order to form binary coordinates of NASA on Murph’s bedroom floor.
