What? where is it called an analogy ?

It's not an analogy buddy but it's just a supposition and it's just a fantasy in the end because it can be seen from the main word mentioned by the OP in his thread starting with “if” and I think we know if it's not an analogy in the end.

Regardless of whether the OP believes or not then when he says that if there is a time machine indirectly it is a fantasy that obviously can't happen right?
A time machine would only be a fiction that exists in movies or cartoons.
