World News
A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Scientists may have solved the mystery behind transporting some of the materials to the pyramid site: a dried-up a river
Fixed the title for you.
The construction of the Giza pyramids is still baffling. Some of the stones are purported to weigh 80 tons. That's four or five times more weight than what modern trucks can pull on paved roads.
It's not so farfetched to presume that this ancient civilization employed technology that is lost to time. I'm not talking about aliens and laser beams, but good ol' fashioned mathematics. They could have exploited a principle of leverage and incline that we simply don't understand or recognize. Or perhaps something entirely different from our six simple machines...
The problem with this theory, of course, is that we like to believe that humanity is always progressing and that we are superior to our forebears by default. That is ultimately a subjective opinion.
For the record we do understand how they built it.
They used log rollers, ropes and lots and lots of people hauling. They brute forced it… which, the reason our trucks can’t haul that much has far more to do with the weight on the suspension and fuel efficiency. They said fuck-all to efficiency and literally threw bodies at it.
That said, We do sometimes need much heavier loads
It’s a fairly common solution- the Moai heads on Rapa Nui (easter island) and stone henge also come to mind. In the case of Egypt, they used a sled (or sled and rollers.)
For getting it up the face, they used packed earth ramps that they later removed. Actually, we still use this technique in construction today. (Specifically to get vehicle access up otherwise too-steep slopes)(and again, threw bodies at it. Lots and lots of bodies.)
There’s really only a few things that are impressive about the pyramids. The first is the sheer ego it took to order it built. Then there is the celestial alignment between all of them. And finally the sheer scale of the project and vast amounts of human labor that went into it.
What they determined is that the river allowed the blocks to be floated much closer than previously thought (even today barges are superior to trains, never mind trucking.)
There's a new theory that the ramps were actually internal. I like it because it means they don't need to bring a lot of extra material and manpower to the site just for the ramps since they're built into the structure of the same material.
I've also heard of this. It seems to me that this theory should be easy to confirm with some sort x-ray or radar or lidar or something, so that we can see the shape of the structure beneath the superficial layers...
