Is it normal to be irrationally afraid of black holes?
They're theoretical. I know. And I hope they stay that way. Forever.
Imagine: a big black hole in the sky, growing larger and larger, until finally it reaches you, a huge black circle of nothingness, sucking in light and air. It disintigrates your everything. You are now neither dead nor alive. You're gone.
Whenever I'm in a ride, like space mountain for example, it freaks me out when, say, I start zooming into a big black hole meant to look like one. I remember going through that and thinking, "very funny."
