    It would work, but only in the impossible world where you have a perfectly rigid unbreakable stick. But such an object cannot exist in this universe.

    Pick up a solid rigid object near you. Anything will do, a coffee cup, a comb, a water bottle, anything. Pick it up from the top and lift it vertically. Observe it.

    It seems as though the whole object moves instantaneously, does it not? It seems that the bottom of the object starts moving at the exact same instant as the top. But it is actually not the case. Every material has a certain elasticity to it. Everything deforms slightly under the tiniest of forces. Even a solid titanium rod deforms a little bit from the weight of a feather placed upon it. And this lack of perfect rigidity means that there is a very, very slight delay from when you start lifting the top of the object to when the bottom of it starts moving.

    For small objects that you can manipulate with your hands, this delay is imperceptible to your senses. But if you observed an object being lifted with very precise scientific equipment, you could actually measure this delay. Motion can only transfer through objects at a finite speed. Specifically, it can only move at the speed of sound through the material. Your perfectly rigid object would have an infinite speed of sound within it. So yes, it would instantly transfer that motion. But with any real material, the delay wouldn’t just be noticeable, but comically large.

    Imagine this stick were made of steel. The speed of sound in steel is about 5120 m/s. The distance to the Moon is about 400,000 km. Converting and dividing shows that it would actually take about 22 hours for a pulse like that to travel through a steel pole that long. (Ignoring how the steel pole would be supported.)

    So in fact, you are both right and wrong. You are correct for the object you describe. A perfectly rigid object would be usable as a tool of FTL communication. But such an object simply cannot exist in this universe.






  • Because it’s clearly being banned, not because of privacy violations, not because of the nefarious impact of a foreign government, but because of the content that is shared on it. It is the only major social media platform with a strong pro-Palestinian viewpoint on it. And the people in Congress have been caught on camera explicitly stating this is why they want to ban it.

    I hate Tiktok. I don’t use it. Never have. But I still don’t want to see the US turn its internet into the Great Firewall of China 2.0.

    The leaders in Congress cannot stand the idea of there being a social media platform that is popular in the US that isn’t hosted in the US. Why? The answer is simple - control. All the US social media platforms are heavily influenced by the US government. Hell, most of them openly contract with the NSA. Facebook is an NSA contractor. These platforms get a ton of money from the US government. And despite what conservatives bitch at in regards to “being censored,” the real censorship is against anything that doesn’t advance US power and influence. Outside of Tiktok, the major platforms heavily censor pro-Palestinian messages and stories. Go to r/worldnews and post anything other than “Palestinians deserve to be vaporized,” and you’ll be banned within 5 minutes. It’s literally that bad. Even when outright bans aren’t in place, the platforms will severely down shift any pro-Palestinian content and keep it out of peoples’ feeds.

    No, it’s about having the infrastructure for it. And even car infrastructure is a huge luxury compared to bike infrastructure. It costs cities 10x to support one car commute as it does to support 1 bike commute.

    Most people just live in areas that demand that luxury transportation be the only form of transportation. That doesn’t mean cars suddenly are no longer luxuries, simply because your area chose to make practical transportation options impossible. You can pass a law making stretch limos the only road legal vehicle. That won’t change the fact that stretch limos are ridiculous luxury vehicles.

    That sounds like an infrastructure problem. If you built roads that were only accessible by literal monster trucks, would you try to pretend that monster trucks are suddenly practical necessities instead of ridiculous extravagances? Your aunt just lives in an area where they decided that it’s OK to require people to make a big luxury purchase just in order to get around. It may be necessary to buy a big luxury in some areas, but that doesn’t mean cars suddenly become the transportation of the working class.

    You have to have to be suffering from a severe case of motornormativity to believe the clown math that a $2k purchase is a luxury while a $40k purchase is a necessity.

    I’m talking the machines themselves. A car costs 10x what an e-bike does. Yes, infrastructure sucks in many places. That doesn’t change the fact that a car is objectively a luxury compared to a bicycle. You live in an area that has made getting around in a luxury vehicle the only practical option. That doesn’t mean cars aren’t luxury vehicles. People who live in areas that mandate that the all homes must be at least 10,000 ft^2 don’t automatically become poor.

    Cars are a luxury, while bicycles are utility. We just build our cities with classism in mind. We build our cities to require expensive luxury travel modes, all in some misguided attempt to keep the poors out.

    I’m just talking basic economics. A car costs 10x what an e-bike does. A car is, by any logical definition of the word, a luxury purchase compared to an e-bike. You just live in an area where you’ve decided that everyone needs to get around in luxury vehicles, and you’ve built that into your infrastructure. This would be like building all of our infrastructure to only accommodate stretch limos, and then trying to argue that limos are a necessity. It’s comically absurd. It’s a clown world.

    Why are you talking about infrastructure? You’re changing the subject. Obviously the infrastructure needs to support them, just as cars are pretty damn useless without good road infrastructure. But cars are objectively an order of magnitude more complex and expensive than e-bikes. Cars are a luxury, bicycles are a utility. The key problem is that many cities are built to require you to use the luxury means of travel instead of the affordable utilitarian ones.






  • A third term really isn’t that much of a stretch. The 22nd Amendment was poorly drafted. Or perhaps more specifically, poorly drafted for our political era.

    In order to approve a Trump third term, SCOTUS really wouldn’t need to come to an incredibly stretched conclusion. According to the letter of the Constitution, the requirements to be president such as term limits only apply to being elected president. Read from a strict literalist perspective, these requirements don’t apply to achieving the powers of Acting President through the line of succession.

    So Trump could get a third term through being appointed Acting President through the line of presidential succession. He would have two flunkies run for President and Vice President. They run promising to immediately resign after being sworn in. MAGA arranges to have Trump appointed Speaker of the House. When the two flunkies resign, Trump would immediately become Acting President and serve the remainder of the flunky president’s term. In terms of actual powers, there is virtually no difference between being President or Acting President.

    Again, it really wouldn’t require a super stretched interpretation of the Constitution for SCOTUS to rule this as a valid method. The writers of the 22nd Amendment wrote the amendment to say, “No person shall be elected to the office of the President…” They should have written it, “No person shall be elected to or hold the powers of the office of the President…” They didn’t consider that someone could try to deliberately become president in a way that doesn’t involve being elected president.

    There’s never been case law on this, because no one has ever been vain enough to try and use this loophole to get a third term. But according to a strict reading of the Constitution, someone can absolutely serve a third term this way. Hell, this would also be a path for someone like Elon Musk, who is not a native-born citizen, to become president.



  • And if those walk out or sit ins were successful, would people not also die? Imagine a vast coordinated effort. Thousands of climate protesters break into various oil processing and refining plants and do everything they can to disrupt operations without killing anyone directly. They throw emergency stop switches. The close valves and epoxy them shut. They drain critical pipe segments and then cut them open with torches. And they chain themselves to equipment. Or maybe they just force everyone out of the facility at gunpoint and set the whole place on fire. Through their efforts, they substantially reduce US oil production for a period of time. That’s what a disruptive protest of the kind you’re suggesting looks like. Direct action against the most offending industries, done in a way that takes no human life.

    And yet, people would still die. What good is an unblocked road if you don’t have fuel? People would lose their jobs because they couldn’t afford the fuel. People in critical condition would die, unable to get to the hospital.

    The point is that any event that actually seriously disrupts the operation of any major company or industry is going to inevitably hurt regular uninvolved people as well. We live in a system and all that.

    And the point of blocking roads is not to “draw attention.” The point of direct actions like that is to cause economic disruption. The key thing to keep in mind is that the truly wealthy are highly diversified in their investments. Those with the real power to change things aren’t moved by a single factory somewhere being inconvenienced. Change in societies like ours really only happen when the reform movement, whether peaceful or violent, grows to such an extent that it risks taking a serious chunk out of nationwide GDP. All the people at the top really care about is money. And there really isn’t any way to hurt them financially without throwing a wrench into the gears of the entire economy.

    That is ultimately what it took for the Civil Rights movement to secure its victories. Black people then were around 12-15% of the population. That number of people is never going to be able to secure their rights on their own through the ballot box. But even 1% of the population working together through direct and indirect action can be enough to grind an entire national economy to a screeching halt. Historically, that is what it has taken for any group to ever secure rights from their oppressors. Asking nicely never works. It always comes down to, “compromise with us, or we will (metaphorically or literally) burn this whole place down.”

    Change and reform are disruptive by nature. There is no such thing as a successful reform movement that only hurts a few narrowly defined perpetrators.
