If you have a tree to the east of you and a cabin to the west of you, you are essentially claiming that you can lay down and pull out your string, connect the two, and prove that the tree is pointing at the cabin. What kind of argument is that?
I genuinely don’t know how a tree can “point” at a cabin. What are you talking about?
You are laying down on the ground and see a tree on one side of your vision, and a cabin on the other. You take out the string, connect them together, and have "proved" that the tree is pointing at the cabin.
That is exactly what the "string experiment" is. You are proclaiming "It's an illusion, see proof. The Moon is pointing at the sun and the string experiment broke the illusion!" In reality it did no such thing.
Take the string and hold it out an arm's length at the tree and the tree will project into space. The same occurs with the moon.
If you are laying down on the ground and see the moon pointing upwards on one side of your vision and see the sun setting on the other, a string connecting the two will no more prove that the moon is pointing at the sun than it would prove that a tree is pointing at a cabin.
The upwardly pointing Moon in the east is directly anagolous to an upwardly pointing tree to your east. The Sun on the horizon is directly anagolous to a cabin to your west. The whole string thing is an erroneous thought experiment originated by a desperate astronomer
