Chemical names in English are all bullshit, either ancient, or based on a 300 year old scientific understanding, or just some made up shit like picrel. ITT we rename the elements with the benefit of hindsight. Some example ideas:
>oxygen
Breathburnium
>silicon
Transistorium
>iron
Magnesium
>gold
Moneyum
>carbon
Lifeium

Why doesn't anyone question the theory that gravity is the curvature of space time? It's pretty silly if you think about it. Space curves around an object but what is it that moves other objects towards it? The gravity? It is circular reasoning.
Also, think the curving of the space-time would only bring objects closer together once. Space does not curve indefinitely towards the object of greater mass, but only once. However, objects are CONSTANTLY attracted to it. Which implies a constant energy. Where does that constant energy come from? Relativity doesn't explain it.

>you can move through time without moving through space
Again, you're thinking in terms of Newtonian physics. Space and time are not separate things, they are one thing, spacetime. Moving through time means moving through space and vice versa.
>And if the rotation of earth is what makes things move but then their trayjectory is redirected downguards due to gravity, then shouldn't objects move at least a little horizontaly before falling down?
No because they're in our frame of reference, the apple, us, and the earth are all moving in the same frame of reference, hence when you drop an apple it appears to be falling straight, but it would appear to move horizontally with the direct that the earth was spinning in another reference frame.

What are you saying, that between the apple and the ground the spacetime shrinks or something like that? Otherwise idk what you guys mean when you say things move cus relativity.

If only he had a paper demonstrating that.
He's full of shit as usual. On galactic scales QI is just MOND without the external field effect. MOND cannot explain the bullet cluster without dark matter, so neither can QI. He's just waving his hands.
Clusters are not single bodies, they don't really have spins. And I seriously doubt the net rotation of the two clusters is aligned along the collision direction, that's quite unlikely. Another claim he pulls out of his ass.

Wut? No. They were well aware those experiments were dangerous. The demon core had literally killed Slotin's colleague (Daghlian) months before, and Slotin had witnessed him dying a horrifying, agonizing death in the hospital, then continued conducting the experiments exactly the same way. They even had shims that they were supposed to use to make sure the core would never be closed and Slotin moved them out to do the experiment with the screwdriver instead.

They just heard the abyss calling, and decided to see how close they could get.

Do you mean within the United States? Because the hispanics are conquering this dying country and they will get a bigger share of the spoils than some Asian immigrant community.

I'm not sure how this is a /sci/ discussion, but also I don't buy your analogy.
The Philippines is still a heavily Catholic country and many still have Spanish names, and there's up to 1.8 million speakers of Spanish there still... by comparison any Arab speakers in Spain are probably people born in Morocco. Spain expelled Islam centuries ago, crucially, it preceded the hundreds of years of Spanish rule over the Philippines.

Are UFO threads welcome on /sci/? I just saw news of the blockbuster revelation that Albert Einstein's assistant from 1947 stated shortly before dying in 2015 that she and Albert were flown to Roswell and saw 5 bodies wearing suits as well as the craft, which Einstein inspected.

Add this to the leaked CIA memo from 1997 where they state the 1995 film Alien Autopsy is, in fact, the Roswell autopsy footage it originally claimed to be.

When they remove the black from the eyes and it's some kind of contact lens...cosmic ray protection + display/personal computer? that shit makes my skin crawl. doesn't seem like the type of thing someone would just creatively make up.

The CIA memo was part of a trove of verified real stuff from what I read. It states the footage is real.
