Why falsifiability is a false guide to what is and isn’t science
I had a liberal arts education, which means that I mostly use what I learned to post nonsense on Twitter. However, thanks to my advisor, I got a solid grounding in the philosophy of science. While I’m certainly no philosopher myself, I also (hopefully) have a less simplistic view of how science works and doesn’t…

A glowing filament shows us where the dark matter hides
Astronomers have identified a filament in the cosmic web, which is the pattern formed by dark matter. That web in turn dictates the distribution of galaxies, since the dark matter attracts ordinary matter — atoms — through its gravity. However, it’s hard to spot the filaments connecting the different halos of dark matter, because…
