Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.

Well one is a physical phenomenon and one is a mathematical type of model. So without going further into the article I assume they use topology to model quantum behaviour.
Its like saying light and sine waves are inextricably linked. One is reality and one is the abstract model to help understand that reality
Sorry for not including the link to the article. Edit: here is the published paper
That's a great example, thank you. So we're beginning to discover a way to model of the fabric of reality?
I am no physicist so I wouldn't know lol
I can tell you about topology though, its essentially a way to talk about a space where points don't have a distance to each other. By that I mean there does not exist a function to measure the distance between two points, which is fundamentally different from "all points are so close we cannot measure their distance". In the latter case a distance might still exist in reality, its just our instruments are not fine enough to detect it. What we mean however is that it makes "no sense", for whatever reason, to talk about distance. The main thing of topology then is that we can still talk about properties of a space, for example whether any two points on a surface can be connected by a path, even though they don't have a distance to eachother or to any of the points linking them.
You definitely lose a lot without the possibility to measure distance but not as much as one might expect. Another example would be that it is possible to distinguish between a torus and a sphere (or any other genus).
