  • That’s the thing. The math says they’re both correct, and that it depends on the viewpoint of the observer.

    I’m inside a car moving at 60 mph. I throw the ball forward (let’s ignore air resistance) at 30 mph.

    Me, who’s inside the car, sees the ball move forward at 30 mph.

    You, who’s outside the car, sees the ball move at the car’s speed PLUS the throw speed (60 + 30 =90 mph)

    So, the ball is moving both at 30 mph and 90 mph. How can that be? It depends entirely upon your reference frame (inside the car? Outside the car? Inside another car moving at 40 mph?). The ball moves at all these speeds, and they are all “correct” within universal terms.


  • With your example, nothing is “moving”.

    Imagine a giant wave in the ocean that is almost lined up perfectly parallel to the shore. Imagine the angle that the wave is off by is astronomically small (0.0000000001 degrees off from parallel). Also imagine the shore line is astronomically long (millions of kilometers).

    One end of the wave will crash the shore slightly before the other end of the wave at the opposite end of the shore. The difference in time between the two sides of the shore is also astronomically small (so small that not even light could reach the other end in time)

    Now let me ask you: did the wave “crash” travel faster than the speed of light? Of course not. I think that is a similar analogy to the laser movement concept you described.

    Edit: Fun thought experiment. Depending on where you are on the shore (which end you are closer to), you may see one end crash before the other end (one event happening before the other event). Have two people at different locations on the shore, once they meet up with each other, they might disagree on which end crashed first! And they would BOTH be correct! Relativity is fucking crazy

    Few questions:

    How far away is the pizza place? Do you live in a remote area? What time of day is it? What are the driving conditions like (snow/rain/other hazards)?

    You say you can just pick it up for a quarter of that price. Then go pick it up? Is there anything preventing you? Not saying this is reasonable on DoorDash’s end, but there’s a ton of information we’re missing here. So I don’t understand how people can jump to certain conclusions this quickly.






  • Omg the logic in this comment is miraculously inconsistent. I’m honestly impressed with the fact that this came into your brain, proceeded to flow out of you into the keyboard, and not once did you stop yourself to think “wait a second, does what I’m saying even make sense?”

    Congratulations. This is probably the dumbest comment I’ve read in months 👍



  • I think people in positions of privilege can recognize their status, and, in my opinion, have a duty to do more (whether it’s donate to orgs fighting this, or donate time if able to be more flexible with their time and work commitments, etc. ).

    There will be people who will be able to take greater risk because they are privileged. There are less financially secure individuals who won’t be able to take as much risk. That’s OK! We don’t need to turn this into a dick waving contest of “who is doing more”

    What we don’t need is this bickering amongst ourselves. We’re all proletariat. Some proletariat will have more privilege. And getting the less privileged working class to attack the slightly more privileged/wealthy wage slav- I mean “workers”- is EXACTLY what they want!

    DO NOT give the bourgeoisie what they want, c’mon now.
