Word/Phrase when you've identified a grand, but sort of irrelevant, injustice/tragedy?

Question

I was trying to tweet about some cosmic injustices and wanted to describe it better than just saying "unduly sad", or "unfair". Any suggestions?

Examples of the emotional state I'm trying to describe: When you realize that mankind will likely never expand beyond our local global cluster and you feel sad, even though the local group is still pretty big.

We should be thrilled about recent increases in life space, but when you are actually unduly feeling cheated because Adam and Eve maybe lived to 900, even though you know that probably isn't even accurate.

When you are sad to learn the sun will expand and burn up the earth in few billion years, even though that is a ridiculously long time from now.

Answer 1

I'd say this is a case of weltschmerz.

Weltschmerz (from the German, meaning world-pain or world-weariness, pronounced [ˈvɛltʃmɛɐ̯ts]) is a term coined by the German author Jean Paul and denotes the kind of feeling experienced by someone who believes that physical reality can never satisfy the demands of the mind.
