Honestly the scariest thing in the universe is seeing an animal being brutally eaten alive. Sure there are existential fears, but an animal being eaten is grounding, and as a living creature, that could be eaten, it should scare you. Death in general is probably most peoples greatest fear

All these people bringing up oort clouds, black holes and the vastness of space alienate themselves from the very real , human reality that we are all about to die soon and we have no idea what that means, probably oblivion

So being excruciatingly torn to shreds by a massive terrifying bear and being cast into nothingness is probably the scariest prospect

Ah nvm just realized im in r/space, so i get it. My point stands
