Gathering matter into one place heats it up, and prevents it from cooling (more or less - the outside can cool but thanks to the square-cube law that's basically negligible on universe-sized masses.)

If you wait for the temperature to drop, and the universe is expanding, distant galaxies will recede to the point that they are now moving away faster than the speed of light and their matter is no longer available to contribute.

650 AU is quite far away. To get there in a reasonable time frame (a few decades), you have to be going quite fast, on an escape trajectory out of the solar system. If you wanted to be on an elliptical orbit, the orbital period would be ove

Yes, you'd need to get quite far from the Sun to use it as a lens - about 650 AU is where it starts becoming practical. It would also not be re-orientable, so any "telescope" launched to that location would only be able to ob

The forces are pretty much shear forces in the plane of the PCB, which traces can handle reasonably well. Also, the amount of force per trace is very small - the motor only has significant torque because there are many traces per PCB multip

You could do a lot in assembly (which uses instructions like JNZ for "if"), as long as you don't need any floating point math.

Why would you do that in JS rather than just using cron for it?

I still use Sailfish OS, but it's becoming more frustrating with more and more things locked into proprietary apps (which are only available for android and ios) with no option to do things over a web interface. Just the other day I ha

interesting. They claim 0.3 seconds on a consumer GPU; I thought that might scale to 30 seconds or so on CPU but gave up waiting after twelve minutes.

It's $26 on Mouser, which seems like a reasonable price.

My biggest issue with mcmaster's website is that it doesn't provide any sort of navigation hierarchy - if you go into, say, the "rounded head screws" subcategory, there's no option to get back to the general "s

Also, many pieces of software whose "documentation" is just some examples of its use.

If we did have a tennis-ball-sized black hole out beyond Neptune, it would be far beyond our capabilities to locate and track - we can barely track debris that small in low Earth orbit, and black holes aren't even courteous enough to p

Yes, but that only becomes a win if the new panels cost less than 20% more than existing ones.

No. SpaceX's Dragon spacecraft has a cargo variant which regularly makes uncrewed missions to the ISS and back (and was doing so for several years before they ever flew with people). There are other uncrewed spacecraft such as Cygnus,

Apollo 11 was close to running out of fuel during landing, as it turned out the planned landing site was full of large boulders which couldn't be seen until the astronauts were actually there.

Not all state is necessarily transmitted over IR. For example, my unit has a button on the remote to turn the LED on or off; over the air this is just a toggle, only the AC knows which state the LED is in. (That said, that particular issue

While stepper motors produce torque based on the current flowing through them, electrostatic motors produce torque based on the voltage applied across them. As long as the motor is stationary, the voltage does not need to change, which mean

This looks like an interesting project to follow! Given the current lack of a portable option from Sony it would be interesting to see how this might run on the Steam Deck.

While that's true in the ideal case, there are still many areas in America where you need significant range to make it from one charger to the next. I have a Leaf which can fast-charge via Chademo, but the low range means that if I go

How much tolerance does that have - can it run directly off a 3.7v lithium ion battery?

Surely it's not an atom because it doesn't have electron orbitals? (Although I suppose electrons could orbit it, in the classical sense rather than the quantum sense!)

Is it VRML or something related?

by skykooler 2y ago
Doesn't VR generally require high framerates at high resolution? Gaussian splatting seems to be one of those borderline-realtime things right now which can't run at 4k120fps yet on consumer hardware.

It depends on the representation. SDFs can be pure mathematical functions, in which case there is no grid, or they can be a grid of values representing distances to the implicit surface, in which case they do use a grid. The latter represen
