Today I Learned
What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

I have such a hard time accepting that this isn't something almost everyone knows. It's such basic knowledge, it's taught in schools and mentioned often enough in any kind of media etc. Seeing this thread is like finding out people don't know that fries are made of potatoes.
I can't speak for anyone else but I definitely didn't have gravity explained in school as the rotation of an objects 4-vector due to a temporal gradient.
Hey everyone get a glimpse of this loser!
The understanding I got from school was that gravity might be some kind of force and basically one mass attracts other mass, like electric potentials do
Keep in mind, that was 20 years ago. Our understanding might have changed and tbh I wouldn't expect a high school physics teacher to be on the bleeding edge of research in all physics fields
If this surprised you...You're in for a world of hurt when you realize how little we all know
Start to specialize in one thing like a trade or a hobby and you'll find the world chock full of information with no possibility for anyone to learn or even familiarize themselves with
Hey now, I wouldn't say that. I'm a super-interested individual when it comes to physics, astronomy and the like and I feel like I have a decent grasp on the lay-versions of what we seem to know as of 2024. But I also know that I'm constantly on the hunt for new information, documentaries, etc. on the subject. Ain't no way that "almost everyone" is putting nearly the same amount of time being interested in this subject matter. This isn't pop culture (though maybe it should be😉).
Yaaay. Here, for your skills in understanding of space and time better than random internet you get the "I am smart" award.
I'm sure I've read about this before but I couldn't say I really "know it". It's not something that ever comes up in my day to day life so I haven't internalized it and probably wouldn't be able to answer correctly if someone asked me how gravity works. I'd probably give the if first explanation about objects attracting each other with mass because that's much more intuitive to me for whatever reason.
