The Two-Body Problem in The Talos Principle 2 will have you solving problems on two sides of a wall. Here is a walkthrough on how to complete it.
The Two-Body Problem puzzle in The Talos Principle 2 puts a big wall between you and the Progress Wheel that allows you to complete the test. This means you'll have to work with a body on the other side of this wall if you want to get the challenge done. Two-Body Problem is Puzzle 6 in the N1 hub and requires the use of the Control ability that you should now be quite familiar with.

With this new body, pick up the Connector and Connect to the red Transmitter and then red Receiver on this side. Place it on the ground and make sure that it is all connected up through the hole in the wall.
