darkness, devouring the sky

On top of the circle there is an arc showing a small frog jumping and landing with RIBBIT and PLOP sound effects.] [caption] More practically useful than the Schwarzschild radius, the *Jumping Frog Radius* is the radius at which an object’s gravitational pull is so strong that even a champion jumping frog can’t escape.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:cz73r7iyiqn26upot4jtjdhk/bafkreie7ex2amt4r4e6xhwf2pvxfejdyi6mv56d3hdfha64wjmp3gkltti)

May have gone a little bit overboard, getting the diagrams just right for the black hole notes I’m writing up for my students.

In 1916, Einstein devised the equations of general relativity. Shortly thereafter, Karl Schwarzschild came up with the first exact solution. His findings predicted the existence of black holes. buff.ly/4kaLDWZ

For those wondering why the two effects are the same order of magnitude, note that the gravitational time dilation is set by the Schwarzschild radius of earth relative to the height of the satellite (local gravitational potential) and the square of the orbital velocity is set by the same quantity.

Le rayon de Schwarzschild d’un objet est le rayon en deçà duquel il faudrait comprimer toute la masse de l’objet pour qu’il devienne un trou noir.

Here's the wormhole equation, briefly seen in on a PADD in #StarTrekSNW's "Off-Hour". My friend Timo, a Physics and Maths teacher, tells me it features a "Schwarzschild metric" but I have no idea what that is... ;-)

sex isn't enough, i need her to compress my body down to it's schwarzschild radius
sex isn't enough, I need them to fold me in half more than 7 times
sex isn't enough, i need her to bite into me and drink my blood

Chicago Fact! Chicago is so small that it recently went under its schwarzschild radius and became a black hole. we call it "the bean"
Chicago Fact! It takes a straight man approximately 3 minutes to walk from one end of Chicago to the other. During such a walk, he will crush seventeen city blocks under his feet
Most don’t know this but Chicago’s nickname is “the smallest city in the world” on account of its minuscule size.

if i don't get my coffee i collapse into an infinitely dense point in spacetime and begin consuming all information within my schwarzschild radius

Antimateria – En 1928, Paul Dirac predijo su existencia y en 1932 Carl Anderson descubrió el positrón, confirmándola.
Agujeros negros – Karl Schwarzschild los describió en 1916 basándose en la teoría de Einstein, pero no fue hasta 1971 cuando se identificó el primer candidato real: Cygnus X-1.

I need to get my old textbooks out. Calculating the Schwarzschild-Radius for a hog is difficult.
