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.

But you want to know what is magic about physics?
Forces. Forces are definitely observable. But they are fictitious. A photon (force mediator of the electromagnetic force) is a packet of energy on the electromagnetic field that creates a curvature in the electromagnetic field such that two particles with opposing charges (intrinsic charge) has that field curved together, resulting in what an observer would see as a force.
Gravity? The thing keeping everything on the ground? Not real. Just a result of the spacetime field being curved by the presence of energy in it. In order to escape the curve, you have to exchange energy, which is to be a force.
The fact that you knew exactly what I was talking about enough to pull up the relevant XKCD is impressive good sir/ma'am/(actually I don't know what the non binary term would be there. I know military it's "Sir" regardless).
