> it's possible for a black hole to have a lower density than water

But that density is not homogeneous. It's much denser in the middle. As you cross the event horizon you wouldn't notice anything happening (as long as the BH is big enough that the tidal forces were small so you didnt get spaghettified). But things would feel very weird as you got closer to the middle.

Probably. Nobody has proved any of this but it seems likely.

You can't build an ordinary 3-sphere in 3D Euclidean space; a 3-sphere is a hypersphere. Are you considering 4D spacetime as the container of the 3-sphere, or did you just mean the volume of the 2-sphere in 3-space (as opposed to its shell area)?

> at 43 percent a lightning strike will cause the entire atmosphere to ignite since it is so high in flammable oxygen

Good article except oxygen is not flammable. Oxygen is the stuff that makes other stuff flammable.

And here I thought there was nothing I would ever suggest we rename after Trump.

I got a used M2 Air a year ago and it's the best Apple laptop I've ever owned. And I've owned dozens.

Plus it runs Asahi linux on the metal.

Yeah it was my cat. One bite and the screen turned black. He was a kitten at the time. Kittens chew on everything.

That happened to my MBP without OLED. Fortunately I had Applecare.

He has a lot of company.

I used to think this was a universal law but then there's Warren Buffett, who's rich but doesn't seem stupid. Of course he's not a tech billionaire.

And then there's Mark Cuban, who is a tech billionaire but who also still seems to have a working brain.

You know how on a computer screen you can just drag any corner of a window to resize it? I had a dream once where I had a phone that worked that way. Want a bigger screen? Just drag one of the corners of the phone. Shove all the corners together and drop it in your pocket.

I used the hell out of that phone all night. Then I woke up and spent about an hour trying to figure out how to build one. I think I could do it in one dimension (i.e. make the phone wider) by rolling the screen around a tiny roller in the edge of the case, and having the case telescope. But that won't work in two dimensions at once. I never figured out how to do it in two dimensions.

When somebody builds one of these, I'll buy one.

Look at this thing. Now tell me how long you think it would last under an assault of, say, three modern $50k military drones controlled by trained Ukrainian operators.

My guess: 35 seconds.

How are running local ones going to become cost prohibitive? Indications are that Nvidia has been channel stuffing (artificially inflating perceived demand), which suggests massive oversupply of GPUs.

LLMs seem to be very good at detecting vulnerabilities caused by using C and other forms of human stupidity.

So yes.

My paramedic colleagues were using fentanyl decades before you heard of it in a recreational context.
