YES! sometimes ago people thought it signals the end of the world. Come to think of it, if the moon never moved away after totality, it would really mark the end of everything

Are there signs that suggests the moon is moving away?

The moon is a natural orbiting satellite, and would continue in its path (the moon might not even know it is obstructing anything, it is just going and minding its business..lol)
Before totality comes the 'Diamond ring.' After totality comes the diamond ring again to signal the moon has started moving away.

So, the moon might just decide to change its path since it doesn't even know it's helping us.
