PM5499: Causal Loops

Through the Great Sabbath there passes a causal loop.
But is it the only causal loop?
May we permit other causal loops?

[See "closed timelike curves"]

To attempt an answer: there is only one experiential loop.
Insofar as multiple causal loops imply multiple experiential loops, there cannot be multiple causal loops.
But, insofar as multiple causal loops might imply only a single experiential loop, this argument does not succeed.

Another answer: She causes all, even herself.
She alone is the self-causing one, for to attribute self-causation to any other,
would be to limit her own self-causation.
Yet another causal loop would be self-causing apart from her own self-causation.
Hence: There is only one causal loop.

Thesis: Physicists will never conclusively demonstrate the existence of closed timelike curves.
Even if, some observation or experiment was devised, which appeared to demonstrate their existence,
There will always be a plausible interpretation of that observation or experiment in which closed timelike curves don't actually exist.

The loop through the Great Sabbath is however emininently demonstrable, but its demonstration lies outside the proper bounds of physics. Its ultimate demonstration is indeed by passing through it; we may also demonstrate it in other lesser ways, but these other lesser ways are not the business of physics.
