Is there another limit in terms of just: how many photons from X object even hit an area of Y telescope apeture size from distance Z in like, say a year? We can't see the thing if no photons from it even intersect our telescope, right?

> I realize now that “a lot of delta-v” is an understatement. 500 AUs is ridiculously far. To get there in under a century you’d need fission-fraction reactors, well beyond our current tech. Voyager 1 is 166 AU away, it launched about 50

Shiny truck trailers have been a failure case. A reflection of the sky in a truck back looks a lot like the sky from the right angle.

I think you could do that, but mass in space is kind of hard to come by. If it wasn't (like if you're on the moon) you could just use the mass for conduction anyway. If you have to ship it up and consume it like that, that's

Yeah, radiative cooling/heating is actually super slow compared to any other type. This is why it's so hard to cool anything in space, it's your only option and it kind of sucks at its job.

True, dust of combustable stuff can be very dangerous if it accumulates, and the things that will combust as dust are not terribly predictable. Eg, flour is a _serious_ explosion risk if it's mixed with the right amount of air.

Closer to home you can get similar things when you grind metals for instance. The sparks are at extremely high temperatures, but won't typically start fires or cause burns (it depends) because they're just too small to impart much

Cool! Is the name inspired by https://www.rockbox.org/ by any chance? That's what it reminded me of, especially given the ~similarities in purpose.

It didn't have the cultural impact of many other shows, though certainly some people know of and have seen it. It's less well known/referenced than even Red Dwarf and other fairly niche shows in my experience.

Science Madness forums may be an okay place to find better references than I'd know about. If you just want to see some fun chemistry and not necessarily take it that seriously or learn to do it yourself, there's some good people

Even if you were okay with all of that, there's still better compounds to use as weapons. It's just not a good one at _all_. It _is_ still dangerous though. A lot of people/writeups discount the danger. You really want to use

If every person price matched every item, they'd be screwed, but: most people don't, many items just can't be, and if eg you're price matching a $20 cpu cooler, you may also be buying a $500 cpu or a bunch of other compo

Someone getting the Nobel Prize and then being assumed correct from then on would be approximately the opposite of science. They can put their ideas out there, and people can evaluate them on their merits just fine, with maybe a bias toward

If it can generate the model (from training data) then presumably that'd be fine, but the iteration time would be huge and expensive enough to be currently impractical. Or yeah if it can modify its own weights sensibly, which feels ...

Doesn't it only practically matter if you're only buying ~one of those things? Who goes to a grocery store and buys one tomato? Feel like that could just round up or round random and it wouldn't be the end of the world.
