Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Mass in seconds? How? I get mass in Joules, but seconds?
There are two possibilities I can think of:
Size doesn't say much about mass though.
I thought stars of similar masses were also of similar sizes. They're not?
I'm no astrologer but from what I've learned, we also need to look at the color to glassify stars into categories. It varies a bit though in each category so it's a blunt tool.
Then there are other objects like gas clouds and even galaxies. For those, we have no idea of the density distribution, so radial size gives us even less info.
I measure the mass of my stool by seconds it takes to discharge
Well the modern definition of a kg is based off of the second and the metre https://en.m.wikipedia.org/wiki/Kilogram :P
The amount of time a mass M attracts a unitary sphere up into CoM.
