  • If you’re into hard sci-fi and you’re looking for a good read, they actually dropped a pretty good recommendation with that reference at the end - Larry Niven does a great job of blending real-world theories like Dyson spheres and advanced propulsion drives, with some of the more far-flung standards of the genre like an intra-planetary teleportation grid.



  • I don’t want to be a downer, but… The rats probably aren’t high if they’re just eating weed. Buckle up, y’all, time for a stoner science lesson:

    THC is present in cannabis in two main forms: THCA and Delta-9 THC. Throwing around those delta numbers can seem scary given all of the unregulated Delta-8 in illegal states, but it’s really not. THCA breaks down into Delta-9 THC naturally with time and heat, through a process called decarboxylization… Which is great, because THCA isn’t psychoactive, while Delta-9 THC is. Because of this, smoking a joint or eating a properly made edible will get you high, but eating an entire ounce is just having a terrible salad.


  • That’s actually a really good analogy. Mind if I throw some numbers on it to flesh things out?

    Let’s set that moving walkway going at 5mph, and we’ll put ourselves on that walkway, on a turned-off rascal scooter. The scooter is stationary on the belt, but it’s still moving at 5mph - that’s your tailwind pushing the air around the plane forward.

    Now, let’s turn that scooter on and throttle it up to 5mph. The scooter is plugging along comfortably at 5mph, but it’s actually moving at 10mph. This is your plane flying with a tailwind, performing normally for its indicated air speed, while having a much higher ground speed.

    Curiously, this does make the phrase “supersonic speeds” somewhat debatable. While they were traveling over the ground faster than sound would, they weren’t moving faster than sound would in the air around them.



  • I’m not a scientist, but one could argue that it’s likely that all three planets had nitrogen, but only Earth still has it.

    I don’t know much about Venus, but I know that part of why we have way more atmosphere than Mars is due to Earth’s magnetic field. Earth has a much stronger magnetic field than Mars, and it does a pretty good job of shielding us from the solar wind; meanwhile Mars has been slowly trickling atmosphere into the void for ages because it lacks that shielding.

    Given that CO2 is actually super heavy, it makes sense that Mars would lose almost everything else first. You mentioned H2, but it’s also almost twice as heavy as N2 - because of this, nitrogen would concentrate at higher altitudes, eventually becoming exposed to the solar wind as lighter gases were stripped away.

    As for Venus… Again, I’m not an expert, but a quick search suggests that it has a weak magnetic field as well. With a primarily CO2 atmosphere and a weak magnetic field, one could infer that Venus is in a similar position to Mars, and any significant nitrogen that may have been in its atmosphere has simply been stripped away by the solar wind.


  • You’re talking about an e-liquid tank full of distillate, kind of like this, right?

    If you just filled it, you should just have to let it sit for a while - I left mine overnight before I hit it to let the distillate soak into the coils.

    If it worked for a while before dying, though, then the atomizer might have burned out. You can replace it, but you’ll have to empty and refill the tank, so it might be easiest to just empty it into a spare tank and use that one for a while.

    Hm… Flower vapes certainly reduce the odor, but they do still smell a bit. If you’re looking for absolutely minimal smell, then vape carts and edibles are probably the way to go.

    That said, I’m by no means trying to discourage you from trying dry herb vaping! It smells way less than flower, and doesn’t linger the way that smoke does. I’d recommend against getting an expensive top-of-the-line flower vape to start with, though; a cheaper entry-level one is a good way to figure out if it suits your needs (and, if it does, to figure out what features you want to prioritize in a nicer one).




  • Honestly, it’s kind of like wine: the more kinds you try, the more you start to pick out the differences; and you can learn a lot about them without any sort of formal education.

    An easy way to do that is by starting a weed journal. When you pick up flower, write down the strain(s) that you got, and then when you smoke it, write down stuff like how it smells/tastes, or how it made you feel. Before too long, you’ll start to be able to pick out things that you liked (for instance, lemon and pine scents, giggly and calm effects) and things that you didn’t like (skunky smell, sort of a racy feeling, too sedative, etc.) about different strains.

    And, really, don’t be discouraged if it doesn’t work or takes a long time. When I picked up from a friend, I really couldn’t tell the difference between most of what they had; and when I picked up from a sketchy gray-market delivery service, there was more of a difference, but still nothing super substantial. It wasn’t until I’d been shopping at a dispensary for like six months that I realized that even though I “just liked weed,” I did actually have a preference for sativa-leaning hybrids with a fresh pine scent.


  • Yes and no.

    Your THC is always degrading into other minor cannabinoids, but it happens very slowly at room temperature. Heating it up will speed that reaction up, though not by a ton until it gets pretty dang hot (this is why bud that’s already been vaped tends to be very heavy in CBN). A week in a hot car probably didn’t do wonders for your preroll, but depending on where it was (direct sunlight or shade, in the glove box or on the floor, etc), the amount of actual heat that the preroll was exposed to could vary quite a bit (my center console stays weirdly cool, for instance, but the glovebox gets very hot), so I can’t say for sure if being left in the car degraded the THC.

    That said, terpenes are quite volatile, and tend to influence the entourage effect of the weed, so you also could have lost enough terps to potentially dull some of the week’s expected effects as well.
