#BlackHoles Are Even Weirder Than You Imagined

It’s now thought that they could illuminate fundamental questions in #physics, settle questions about #Einstein’s theories, & even help explain the #universe.

…In recent yrs, the amt of data that scientists have discovered about black holes has grown exponentially.

Today in History, March 14, 1879, Albert Einstein was born. In addition to being one of the most significant physicists of all time, he was also a pacifist. Yet his letter to President Roosevelt warning of the Nazi progress on atomic weapons research was arguably key to the U.S. implementation of the Manhatton Project, a decision he later lamented. In 1955, well after the Cold War and nuclear arms race had begun, he and ten other intellectuals and scientists, including other Nobel Prize laureates, like Bertrand Russell and Linus Pauling, wrote a manifesto warning of the dangers of nuclear weapons. Einstein also participated in the U.S. Civil Rights movement, calling racism America’s “worst disease.” Later in his life he began to support socialism, and he criticized the Bolsheviks for their barbarism. Einstein was also a Zionist, and supported Jews’ right to return to Palestine. However, he wanted a free, bi-national Palestine in which Jews and Arabs shared sovereignty, living peacefully and equally with each other.

Technological progress frequently results in more unemployment rather than in an easing of the burden of work for all. The profit motive, in conjunction with competition among capitalists, is responsible for an instability in the accumulation and utilization of capital which leads to increasingly severe depressions. Unlimited competition leads to a huge waste of labor, and to that crippling of the social consciousness of individuals.

Watching the BBC documentary on via . Transparently obvious that this was made because of , but at the same time it’s an interesting overview of Einstein’s life between exile from Germany and turning up in the US.

I also thought they were taking liberties with his voice until they showed a clip of the real Einstein speaking. Turns out not so much, though I kinda want to watch more of that now.

The Probe lifted off 🚀 atop a rocket from southwestern ’s 🇨🇳 Xichang* Satellite Launch Centre at 📆 3.05pm on Tuesday. The Einstein Probe is led by researchers of the Academy of Sciences and has major instrument contributions from the and the Institute for Physics in Germany 🇩🇪. It can observe an area of sky more than 10,000 full moons’ size at any given time. In contrast, existing large X-ray telescopes, such as ’s Chandra Observatory, can only image a section of sky smaller than one full moon at a time. It means the Einstein Probe could observe almost the entire night sky 🌌 in just three around , or under five hours ⏱️. https://www.scmp.com/news/china/science/article/3247782/einstein-probe-china-launches-powerful-space-x-ray-observatory-understand-flashes-night-sky

• Our #scientific understanding of #gravity was established by #IsaacNewton in 📆 1687.

• In 📆 1915, #Einstein published "The General Theory of #Relativity."

#DarkMatter was first theorized in the 📆 1930s to explain movements of #stars 🎇 and #galaxies 🌌 that couldn't be explained by Newton's laws of gravity.

• Modified Newtonian dynamics (#MOND) was first proposed by Mordehai Milgrom in 📆 1983. https://www.youtube.com/watch?v=Qkl2ASn9yyA

• Recently, a new study has found direct evidence for a modified theory of gravity based on #Gaia telescope 🔭 observations.

There is an even more recent paper that in detail shows that wide binary stars are actually evidence against modified gravity.
