Dark Matter Makes a Stunning Comeback
After being written off by a team of European astronomers, dark matter has made a surprise comeback thanks to the training and support of two researchers from New Jersey.
What's the Latest Development?
Last month, a team of researchers found dark matter mysteriously absent in the region around our sun. Having mapped more than 400 stars, spanning a region roughly 26,000 light years in diameter, the European Southern Observatory identified a quantity of material that matched what could be directly observed, such as stars, gas and dust. Because all the matter in the region could be directly accounted for, doubt was thrown onto the strength of the dark matter hypothesis, which posits the new, yet-to-be-observed matter as a mathematical necessity.
What's the Big Idea?
Astronomers from the Institute for Advanced Study in Princeton, NJ, however, now argue that the European team made fundamentally poor assumptions which resulted in incorrect measurements of stellar mass. "The researchers point out the stars within the local neighborhood move slower than the average velocity assumed by the ESO team, in a behavior called asymmetric drift." When the velocity of the selected stars is adjusted, the calculations not only suggest the presence of dark matter but that its density is unusually high around the area of the sun, up to 20% greater than has previously been measured.

Is it "perverseness," the "death drive," or something else?
A disturbing interview given by a KGB defector in 1984 describes America of today and outlines four stages of mass brainwashing used by the KGB.
- Bezmenov described this process as "a great brainwashing" which has four basic stages.
- The first stage is called "demoralization" which takes from 15 to 20 years to achieve.
- According to the former KGB agent, that is the minimum number of years it takes to re-educate one generation of students that is normally exposed to the ideology of its country.
It's up to us humans to re-humanize our world. An economy that prioritizes growth and profits over humanity has led to digital platforms that "strip the topsoil" of human behavior, whole industries, and the planet, giving less and less back. And only we can save us.
- It's an all-hands-on-deck moment in the arc of civilization.
- Everyone has a choice: Do you want to try to earn enough money to insulate yourself from the world you're creating— or do you want to make the world a place you don't have to insulate yourself from?
