  • Oh we can rule out actual discourse on Lemmy, this platform’s already dead in the water. There’s too many ass burgers on here who will take an extremely literal and narrow interpretation of the series of words you typed ignoring any nuance or implication and assuming the examples you chose to cite are the only that exist. At least a few of them are probably employees of the Russian, North Korean or Chinese governments instructed to add truckloads of bad faith to every corner of the English speaking internet.


  • By what mechanism does the far side get more sunlight? Because it’s never sees…what would we call them from the Moon’s perspective? Solar eclipses? Terran eclipses? Every single New Moon the far side is fully sunlit, but on occasion on Full Moons the Moon flies through Earth’s shadow?

    The far side can get darker than the near side. During the lunar night, the near side experiences earthshine, which is significantly brighter than the moonshine we get here on Earth (Earth is larger in the sky and has a higher albedo; bigger and shinier reflector than the Moon)

    I propose we call the near side the dark side, because it has almost all of the maria - the dark basaltic lowlands. The far side of the moon is mostly relatively lighter grey highlands and so appears lighter than the near side.


  • Venus is difficult to photograph for the same reason as Titan, thick opaque atmosphere. We’ve got radar imagery of Venus, plus the Soviets landed some probes and took a few pictures of the actual hell that surface level Venus is.

    We can actually get a pretty good look at Mars from here; This is a picture of Mars taken with Hubble. We have active missions in orbit and on the surface of Mars as well so we can look at it as close as we want.

    Meanwhile, this is the best Hubble could do with Pluto. And that’s still inside our own solar system, we’re not getting any photos of the surface of Earth mass planets around other stars.


  • You’ve only ever seen photographs of one planet with oceans and landmasses, and that’s Earth. The only other celestial body that has a solid surface with liquid on it that we’ve taken pictures of is Saturn’s moon Titan. Titan has a thick opaque atmosphere so we don’t have true-to-life pictures of the surface from space. We’ve got images constructed from radar scans, and this amazing image taken from the surface by the Huygens probe that hitched a ride with Cassini. The hydrocarbon lakes of Titan look like…blobs on a circle.

    Every other planetary surface you’ve seen is rocky dirt, icy dirt, straight-up ice, cratery dirt, or opaque gas clouds. Any “earth-like” planet you’ve ever seen is a fictional artist’s conception. And ain’t no human artist who knows shit about plate tectonics compared to the Earth herself, so they draw weird shit that ain’t quite right somehow.



  • You’re an ill-informed English major. You instructed me to call you that, so I did.

    The light source for this image is the Sun.

    “The dark side of the moon” is a phrase that seems to have a strange effect on people; they seem to use that phrase to incorrectly mean the far side of the moon, and then that puts the idea in their heads that the far side is always dark. It isn’t; the far side is fixed, the dark side is constantly changing.

    The Moon is tidally locked to Earth, this means the moon’s rotational speed and its orbital period are the same, the moon rotates once on its axis for every one orbit of the Earth it performs, meaning it doesn’t (significantly) rotate when seen from Earth. No human saw the far side of the moon until the Soviets flew a satellite around it, and only 27 men and 1 woman have ever seen it with their own eyes. Until this week, those numbers were 24 and 0.

    It is hidden from us but not from the Sun; we observe the Earth waxing and waning, being full and then half a month later being new. When the moon is new, the near side is in darkness and the far side is in light. On the Lunar surface, a day and night takes an entire month, while the continents and oceans of the Earth hanging still in space overhead whirl past nearly 30 times.

    Finally…the image above isn’t the whole far side. About half of the near side is visible; the big dark patch to the right is the Ocean of Storms, most of the Sea of Rain is visible as well. Kepler and Copernicus crater are visible, Tycho is just out of shot, if you look closely you can just barely see one of Tycho’s rays across the Sea of Clouds. That one very dark patch just right of center is Grimaldi crater. All those features are visible from the Earth, in fact two of the Apollo landing sites are visible here, 12 and 14. The very large carter, the dark patch to the left of center of the image is Mare Orientale, which is just barely visible on the edge of the Moon from Earth, from our point of view it’s on the “side”. It’s eastern ridge is visible from Earth but we don’t really see the dark mare itself.






  • Because that kit would cost around what a new Civic would cost, and you’re going to get a 16 year old car made worse.

    EV components don’t really swap into the spots that ICE components do. An engine is relatively large, a motor is relatively small. A gas tank is relatively small, a battery is relatively large. Most ICEs designed from the ground up use a “skateboard”-like chassis with the battery taking up basically all the volume below the floor. The motor can be tucked away somewhere, and then the body built on top. You don’t need the volume in the nose for the engine so you get a frunk. a 15 year old ICE car didn’t portion out the room for the batteries, so you’ve got some of the area under the trunk occupied by the gas tank. That’s about the volume that the batteries in a golf cart take up.

    Anyone who’s capable of designing and manufacturing that kit might as well go into production of new cars.



  • The closest to that I can think of is the Tesla Roadster. Which IIRC was basically an electric Lotus Elise, rather than a Mazda Miata. I wonder how popular electric Miatas would actually be, without a manual transmission.

    The most “normal car that happens to be electric” I can think of is the Slate. With the exception of the powertrain and complete lack of a radio, the controls and mechanisms look like they’re from 20 years ago. The more I look at it though the more I think that car is DOA.


  • I think there’s also a problem with the kinds of EVs everyone tried to sell.

    Tesla has seen legitimate success in making EVs a desirable luxury item. The Prius became something of a fashion statement among kale chip eating Californians in the 2000s because of its alleged economy, but it was still an economy car. It wasn’t that nice or luxurious. Tesla made cars people wanted to drive and be seen driving, with an all-electric powertrain.

    Pretty much everyone tried to copy that business model, making excessively fast luxury sport sedanover blobs with price tags that make car shoppers start muttering the word “depreciation.”

    Meanwhile, EVs tend to be the breeding ground for shit features everybody hates, like touch screen HVAC controls. Nobody wants to make a normal car that happens to be electric, which is what a lot of the buying public wants, but can’t find.


  • I ripped my DVD collection a couple years ago, and I watched that change over time happen.

    The earlier DVDs in my collection came in bespoke packaging designed specifically for the film, they had properly interactive menus complete with easter eggs, commentary tracks, alternate angles, remember when DVD player remotes had an “Angle” button? DVD was a prestige format, it was actually as cool as LaserDisc was supposed to be.

    There was the early mass market phase when older movies, or lower budget current releases were put out on double sided discs that had widescreen on one side and “fullscreen” 4:3 on the other, in those half plastic half cardboard cases, remember those? Higher end stuff would be released in what I think of as the standard plastic DVD case. How much plastic was wasted selling them in packaging other than CD jewel cases?

    Later on, you got the cases that had the recycling logo cut out of them, the discs got cheaper, features started disappearing, because it was now the budget option. “It’s just on DVD.” DVDs were cheap to make, everybody had a player for them, Blu-Ray now had the prestige releases. The Direct To Bargain Bin releases weren’t exactly the high point of the format but there’s still fun to be had there.

    DVD still staggers on, they’re not dead the way VHS is, but it didn’t make it as long. DVDs could do things VHS couldn’t, like TV shows. The advent of binge watching happened on DVD; complete TV series on VHS wasn’t feasible but it works great on DVD. On the other hand, because VHS was the only widely adopted vdieo format for most of its run, you can find weird stuff on VHS that never got pressed onto DVD.


  • I could argue that VHS was a superior format to both Beta and Laserdisc because it offered a better blend of features.

    Laserdisc offered cinemaphile farkles like perfect pause and frame by frame, additional audio tracks etc. but a movie required at least three sides of a disc, and thus two discs with at least two changes. Laserdisc was read-only and thus useless for timeshifting and camcorders. The tape-based formats were slightly worse in quality but could hold an entire movie in one go.

    VHS was superior for timeshift and camcorder use than Beta because of the longer run time. There was a mini cassette for miniature VHS camcorders which could be played back on a standard deck with an adapter, Beta never got there AFAIK and insetad Sony went to Hi 8, which never really took off as a home video format the way it frankly should have. VHS was better than Beta at movie distribution because a longer film could fit on an SP VHS cassette, often with room to spare for some commercials at the beginning which helped subsidize the cost.

    VHS was at least capable of everything.

    DVD didn’t fully kill VHS; It unceremoniously killed LaserDisc and shouldered VHS aside a little. Through most of the 2000s VHS was still going strong, DVD-RAM is surprisingly old but wasn’t adopted that widely. Hard drive based DVRs and smart phone based video recording finally did VHS in.
