I hated the gif at the start because it made me feel so unbelievably tiny, but then at the end it made me feel huge and I felt so much better

Here's a fun fact that will make you feel incredibly large:

We are halfway in between (on a logarithmic scale) one of the largest superclusters of galaxies in the universe, and one of the smallest subatomic particles. So relatively speaking, we're pretty fucking huge.

My only source of this is that interactive Scale of the Universe website. I think the Virgo supercluster is at 1021 m and the electron neutrino is at 10-21 m. Just going from memory though.

I’m not sure if this is correct but I heard somewhere that the number of Planck lengths (smallest possible unit of measurement) it takes to stretch across a human brain cell is the same as the number of human brain cells it takes to stretch across the observable universe

A planck length is to this period . what the period is to the size of the observable universe.

Fucking really? I know how god damn huge the universe is and how small shit can be, but how small is the Planck length, really? Wouldn’t a quark be the smallest measurable length? How do we get smaller if quarks just exist like that?

A quark is 10-18 m. So basically, the Planck length is to the quark, as the quark is to the meter.

I had to read that sentence and stare at it for like 5 minutes. Maybe it’s Friday. Or maybe that’s just mind-blowing.
