If 85% of the universe needs to be composed of dark matter for general relativity to work the way it does, isn't it simpler to conclude that general relativity simply doesn't work the way we think it does?
When you presume that the standard model is correct, and that dark matter is needed for it to work, you're way more likely to just point at the few bits of evidence for dark matter detection and ignore all the failed attempts to detect it.
You've already decided on the conclusion beforehand. The experiments and research don't matter.

God is already omnipotent. But, this reality is also here. Very confused, I think we must be in heaven or something else maybe? One theory is that, we don't have to do anything, we don't even need to eat. But, on the flip side, nothing good ever happens unless god wants it. That's what's happening bro I'm pretty sure. So, I may be the most perfect creation because I'm Jewish. You're all like half people. You are warriors of light and you will be sent to the forges of hellfire and brimstone to forge iron goylem made of steel. My IQ is over 300, I've taken over several minor Latino colleges and have been tricking them to breed with niggers. This is going to create the Messiah, an army of niggerspics whose generics are ultra perfect. This new race of sapiens will develop. They will be sent to work in the forges casting iron made of pure steel to press into spoons to feed my slaves. I will be constructing more forges in Africa as my race of genetically perfect super beings level up.

Apparently not!
A new, comprehensive preregistered meta-analysis found that, whether the diversity was demographic, cognitive, or occupational, its relationship with performance was near-zero.

i work with many foreigners. Im a foreigner too. Basically at my workplace we have self-organized in tribes according to general ethnicity, it solves the language problems.
As to productivity, we work as hard as anyone else. Our tasks are mostly individual with barely any need for team work.
Team work is bullshit for the most part, it brings in coordination problems and personality clashes that simply dont exist when you work alone. Team work brings in opportunities for sabotage and dilution of responsibility. Managers promote it as it reduces worker's power and increases management's power. Diverse team work is the same idea but turbocharged.

Why is it controversial to say that human races have mental differences between them? It just doesn't make any sense. Yes, humans have a genetic bottleneck but humans have diverged since coming out of Africa that their physical features can be wildly different. We have the blacks, the pinks, the yellows, the abos. All look very different from each other physically.

There are differences in Race when it comes to medicine. White People are more prone to skin cancer than any other race due to a lack of melanin in their skin. Black people are at higher risks for high blood pressure, certain types of cancers and diabetes. Asians are at higher risks for liver disease than other races. Mixed race individuals are more likely to have these risks offset due to being biracial or multiracial but in some cases their risks of diseases prevalent in their heritage might be higher. Just like there are differences in biological sexes for treatment. Some humans like the Badjao or the Tibetans have evolved higher lung capacity compared to the average human.

So we have all these physical differences, affecting even diseases and medical treatment but somehow mentally we are all the same? That's kinda fishy no?

>A review of the world literature on brain size and IQ by Rushton [Rushton, J. P. (1995). Race, evolution, and behavior: a life history perspective. New Brunswick, NJ: Transaction] found that African-descended people (Blacks) average cranial capacities of 1267 cm3, European-descended people (Whites) 1347 cm3, and East Asian-descended people (East Asians) 1364 cm3. These brain size differences, containing millions of brain cells and hundreds of millions of synapses, were hypothesized to underlie the race differences on IQ tests, in which Blacks average an IQ of 85, Whites 100, and East Asians 106. The validity of the race differences in brain size, however, continues to be disputed. In the present study, the race differences in brain size are correlated with 37 musculoskeletal variables shown in standard evolutionary textbooks to change systematically with increments in brain size. The 37 variables include cranial traits (such as jaw size and shape, tooth size and shape, muscle attachment sites, and orbital bone indentations), and postcranial traits (such as pelvic width, thighbone curvature, and knee joint surface area). Across the three populations, the “ecological correlations” [Jensen, A. R. (1998). The g factor. Westport, CT: Praeger] between brain size and the 37 morphological traits averaged a remarkable r = .94; ρ = .94. If the races did not differ in brain size, these correlations could not have been found. It must be concluded that the race differences in average brain size are securely established. As such, brain size-related variables provide the most likely biological mediators of the race differences in intelligence.

These measurements aren't cranial volume, but volume to body mass, or something like that. If it were purely volume asians wouldn't have the largest (they are on average much smaller peoples than blacks or whites). Regardless it's not volume of the brain that is most important, but how "wrinkled" or contoured it is, coupled with the size and development of the frontal lobe?

if gay is based on identity then it isn't natural since identities are social constructions. if a biological male identifying as a male is attracted to a biological male identifying as a female, and identity is by word alone, not physical characteristics, and that attraction i mentioned between those two people is classified as 'straight' by lgbtqia+ people, then that's all you need to know that gayness isn't natural and is a social construction.

>Last September, astronomers in Japan detected a series of objects in the Kuiper Belt – described by the BBC as a "doughnut shaped region of icy bodies" beyond the orbit of Neptune – that had unusually warped orbits around the Sun. Researchers Michael Brown and Konstantin Batygin, from the California Institute of Technology (Caltech) in Pasadena, speculated that only a massive planet's gravitational pull could explain these "orbital anomalies", said Live Science.

>Then in February, scientists narrowed down the "likely hiding" place of the "elusive" planet after they "whittled away" 78% of the "hypothetical world's suspected orbital pathway", said Philip Plait in Scientific American.

>Qrd?

A species of phytoplankton algae (native to the pacific ocean) has managed to successfully envelope, and assimilate, a species of nitrogen fixing bacteria into its' body as a new organelle. The bacteria is no longer symbiotic, but an actual permeant addition of the phytoplankton's physiology and gets replicated when it replicates and passed on when it has whatever it considers sex.
This is significant for two reasons:
-Nitrogen fixing has previously been the sole domain of bacteria.
-This is observable documented evidence of -I can't remember the word for it- that theory where progressively complex organisms evolved by forming permanent long-term relationships with other bacteria to form their organelles and to in effect become "creatures in a trench coat".

Cherry blossoms bloom in Tokyo, 15 days later than last year, 5 days later than average

https://www.japantimes.co.jp/news/2024/03/29/japan/society/cherry-blossoms-bloom-tokyo/

Cherry blossoms finally burst into bloom in Tokyo on Friday after heavy rain in the morning, marking the latest blooming in over a decade.
The declaration of the blooming made by the Meteorological Agency came 15 days later than last year and five days later than in an average year. Private forecasters had also expected this year's bloom to come much earlier.

Friday’s blooming is the latest in Tokyo since 2012, when cherry blossoms were declared to have blossomed on March 31, according to the agency.

Cherry blossom forecasting is big business in Japan. As early as in January, companies start to issue forecasts for when cherry blossoms will first bloom and reach their peak.

The weather agency, which began forecasting the annual bloom in 1955, sets a government standard for observing cherry blossom trees. For consistency, the meteorological agency only uses data gathered from the Somei-Yoshino variety, which produces pale pink blossoms.

Running off into the ocean is the problem. If it were economical to extract phosphorus from the ocean then we wouldn't be mining it. The best you can get right now is composting seafood waste, but that's not enough to support all of our agriculture.
