Why is happiness a factor in what people ought to know?

Humanity just took a picture of a black hole with a multinational telescope array, predicted by decades old math and all that jazz.

All a few (educated) friends had to say is that the image looks like garbage, what is this bullshit on my frontpage.

I was surprised about how upset these reactions made me. But then I figured there must be a multitude of important things of which I do not have even the tiniest understanding or care.
