How does the grandfather paradox cause a causal loop (and therefore a bootstrap paradox)?


  • Hi - Can you elaborate on this question, please ? It's very briefly worded.

It doesn't.

The Grandfather Paradox indicates a situation in which the outcome of a visit to the past negates the possibility for that visit to happen in the first place.

A causal loop is the state of something (an object, information, or an event) existing without origin and end, as it was caused by what it will generate.

They are mutually exclusive: in the first situation the origin is cut off (but the end is maintained), whereas in the second situation the origin must be causing the loop.
