  • Also, sour patch kids have a weird ingredient in the coating that most electrolyte stuff doesn’t have. Potassiumsomething something, irrc?

    Probably you’re referring to tartaric acid, potassium bitartrate. It’s added to candy to stabilize invert sugars, keeping them from crystallizing. You can buy it in powder form, usually called cream of tartar.

    I don’t know what it does for hydration, but I suppose it would help top up potassium levels.

    So, yeah, bottom line: you only need a delta-V of about 12 km/s to get out of the solar system, but a delta-V of 30 km/s to get to the sun without going into orbit.

    This is true, but the possibility of gravity assists mostly nullifies the difference. If you can get out to Jupiter you can basically choose: either let it sling you out of the system, or let it cancel out all your orbital velocity so you fall into the sun.

    These are all technically correct but fairly inconsequential. Even just to graze the sun you need to lose 90% of your orbital velocity. And although everything orbiting the sun will eventually fall in, the friction is really low. It will take billions of years to lose enough velocity to fall in.

    Note that although species can be described as tree-like, they didn’t quite look like modern trees do. Also, much of the world was swamp, and much of the dead plant material sank into these bogs and decayed into peat.

    The amount of CO2 trapped during this period caused the atmosphere to be around 35% oxygen. This allowed life with inefficient respiratory systems to grow much bigger in size without suffocating, mainly insects. Think woodlice 6 feet long, spiders the size of dogs, millipedes as big as cars, and dragonflies as big as eagles.
