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

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

How, uh, far back in time did you want to go?

That's probably the guy that offered people a few dollars and a chair to watch all of earth's history.

Earth moves with somewhere between 230-500km/s, long term average should be 370 km/s

The solar system and earth formed 4.6 billion years ago.

https://numbat.dev/?q=370+km%2Fs+*+4.6+billion+years+-%3E+ly%E2%8F%8E

That means the solar system travelled 3.45-7.67 million light-years (5.67 for the average speed) since then.

That plural form (millions of light years) is borderline, but actually not incorrect.
