> 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.
Right, oxygen is an oxidizer, not a fuel. A world with 43% oxygen would have some pretty terrifying wildfires, but the sky wouldn't just burst into flames
You mean that the corner was damaged, not that a cat also chewed on the corner of your MBP, right? I'm still in shock that a cat would chew on glass and metal enough to damage it - two cats doing it is too much in one day!
It doesn't mean the money they have couldn't be put to better use serving others.
If there's a law of dimishing return on money owned, the only rational thing is to share with the less fortunate knowing that, say, $5,000 is not even a penny on the ground to you but could feed a family for a year in most parts of the world. Maybe you fed the next Einstein, or helped the next Peter Thiel develop empathy.
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.
Could be 4 screens overlapping each other. Pull the corners and the lower screens pull out from below the upper ones. There would be a visible seam at the boundary, but maybe there's a trick you could use to disguise it.
This reminded me about phones from the TV show Upload. They are wristbands that project a holographic screen. Feels like a cool concept, and just as impossible to build with current tech, heh
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.
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.
