Earlier this week I found a vibe coded web calculator, that allowed code injection. I thought this would be interesting, finding out which functions would be callable and how to exfiltrate data in a plot.Then I realized the input was evaled and the you could get back text by throwing an exception. Where is the fun in that?The biggest challenges where that everything got converted to lowercase and the json encoding was a bit broken so I had to do some f-string manipulation.
The first half of my comment is the one that matters, the second half is a sleep deprived Wikipedia binge.
The units are kg rounded to the next power if 10. The numbers come from reverse engineering the article and Wikipedia. Sagittarius A* was a the first black hole I could think of. The scale was between mass of electron (like in the article) and mass of an atom (relevant to the post).
"Mass of electron cloud equivalent to black hole" what electron cloud?
An imaginary cloud of electrons similar to the one in the what-if. One that has the energy equivalent of the mass of a black hole. Due to the reduced charge density there would be less energy and therefore black holes, but I am convinced that a lot of objects would collapse.
In the example in from that what if, they are putting a universe's worth of mass in the volume of the moon, so it would create a super massive singularity. That's not what is happening in here.
Not quite, xkcd put a moons worth (by mass) of electrons together, so if we add an electron to each atom we go down four to five orders of magnitude.The black hole came about, because the electric charge creates a electric field in which the electrons have a potential energy that by E=mc^2 is equal to the mass of the universe. If we apply our scaling factor we still end up with black holes everywhere.
Lets play with those numbers:Scale factor between Sagittarius A* and the observable universe 1037 / 1053 = 10-16
Mass of Moon 1023Mass of electron cloud equivalent to black hole 1023 * 10-16 = 1013
mass of electron added object equivalent to black hole 1013 * 105 = 1018That means adding an electron to each atom is enough to rival the black hole at the center of the Milky Way. Even if I miscalculated by many orders of magnitude, at least each planet collapses into one.
https://whatif.xkcd.com/140Not quite the the same scale, but a similar idea is explored by Randall Moore. He explores a lot of weird questions like this and regularly consults scientists.
If you want to load at runtime you can use https://docs.rs/ron/latest/ron/. The structs are a weird combination of the two ways to define a struct in rust, making the ron notation of structs invalid rust, but having proper enums makes it worth it.
Point being, an aerial shot of almost any neighborhood is going to look like that.
No, I just zoomed in on a place in my home city that looked interesting from the satellite view, and took these screenshots a few hundred meters apart:
Everybody wants science to cure cancer, but the moment someone does foundational research they lose their fuckin minds.Guys, the alternative is cutting up mice and pigs.
So Iran is behind the F-35 ejecting it's pilot in a thunderstorm and flying away?I thought it was just trying to get out of South Carolina.
