1. Would we even need to build space elevators when we have rapidly reusable super heavy rockets like SpaceX Starship? They can launch fast carrying lots of mass to orbit cheaply. The latest numbers I saw for Starship is 150 tons in reusable mode to low earth orbit and 250 tons in expandable mode. With reuse and mass production the prices could become very low.

  2. No, not really. Space elevators would be cool if we had them right now, but they are incredibly technically challenging and finnicky to actually build. We don't even have the technology yet to construct one. Meanwhile as you said reusable rockets are bringing the cost of carrying mass to space down exponentially by the year. There are also other propulsion technologies in development now that could further that growth. By the time space elevators become technologically and economically viable, reusable rockets will be so far ahead there won't be any point in building a space elevator

  3. I love road trips, and traveling in general. There's a whole world out there, now that you have the travel bug there's so many places to explore

  4. Oh.. gd … that’s a lot. Would that cost 16/96 times as much as charging one phone in terms of power used? (I feel like that might be a really dumb question, but I’m also not 100% sure of the answer)

  5. Power is a rate, like velocity. Energy is a quantity, like distance. Quantity is a a rate X a time, for example: if you travel 100km/h for 2 hours you will have travelled 200km. Likewise think of power as your velocity and energy is your distance. Power is the rate at which energy is consumed, energy is the total amount of energy consumed. The electricity provider charges you based on the total amount of energy you consume, not the rate at which you consume it, measured in kWh.

  6. That DOES HELP! Thank you so much for taking the time to write that! :)

  7. One of my biggest pet peeves is when people mock the Imperial system in favor of the metric system is when they say, "It doesn't make sense! 10, 100, 1000 are so much easier! Why have 12 inches to a foot, 5280 feet per mile, etc...?"

  8. Yes, imperial had its uses, but since the industrial revolution those uses have become increasingly obsolete. You say that imperial's advantage is divisibility, but I fail to see how it is more divisible than metric. I'm not sure how splitting up an otherwise arbitrary number into its prime factors proves its usefulness as a divisible number. I don't see how measuring land by km2 is more complicated in any way.

  9. At the equator, the earth is appropriately 40,075km in diameter. The earth takes approximately 23 hours and 56 minutes to do one revolution.

  10. I believe it does. The definition of solid state is not a device that does not move, but rather a device where its components are based on semiconductors. Which this falls in.

  11. Actually the definition of a solid-state device is precisely one that is made of solid and non moving elements. Specifically excluded from this definition are electromechanical devices. Electromechanical devices are ones that use an electrical signal to create mechanical movement. It doesn't matter if that movement is rotation, oscillation, or deformation, it's all mechanical.

  12. As much as I want to use this as another reason to avoid all apple products, my confidence is low that Google doesn't already do this on Android

  13. Make Apple and Google obsolete, take back control over your own computing with non-proprietary software.

  14. I don't see anything wrong with that. A lot of people listen to classical music and most of that is way older than 1910

  15. It doesn’t have metal in it people jfc it’s just static and the powder particles are so light, they can stack like that.

  16. A headland. Specifically, an isolated headland.

  17. Does a headland have to be high above the water with steep cliffs? That's what I seem to keep getting when I look it up

  18. Don't forget about the infinite mass having it's own infinite gravity, that truck is pancaking against the surface of its tow load

  19. Even in that scenario infinite mass would still have infinite inertia and therefore take infinite energy to accelerate from rest, so it would still be immovable

  20. No, there is to balancing force in the universe, but that's not to be confused with consequences. Bad actions often contribute to negative consequences, just like good actions often contribute to good consequences, but that is not a hard rule of the universe, nor does that mean it always happens that way

  21. If you're gonna use paper straws this is the way to do it. At least the plastic lid won't slice through the straw

  22. Interesting question. Sorry I know I'm late to the party here, but I think I have an interesting perspective to share.

  23. No, it will be so much worse. When your hands are frozen even cool water will feel like it's scalding hot. In fact if you try to warm up your hands with hot water when they're frozen you could cause nerve and tissue damage. The recommended way is to run them under ice cold water and gradually warm it up.
