What do you call something that will not happen because is contradicts the fate? For example, an anecdote. "One day, a train rushed out from poit A to point B. Simultaneously, another train started moving from point B to point A. They both had high speed, and the crash could have been awful. But the trains never met. Just because ". Thank you!
You may use the expression it was not meant to happen:
verb [usually passive]:
- If you say that something was meant to happen, you believe that it was made to happen by God or fate, and did not just happen by chance.
A common expression that I have heard used is 'written in the stars'. Or in the context of the question 'not written in the stars'.
If you believe that something is written in the stars, you believe that it will be made to happen by a force that controls the future
Shakespeare disagreed, however. Or, at least, he put disagreement in the mouth of Cassius :
The fault, dear Brutus, is not in our stars,
But in ourselves, that we are underlings.
Note: The expression 'It is not in the stars to hold our destiny, but in ourselves' is a common misquote of the above line. See Quora.
