It’s possible but not likely or common. Glass is stronger than most people give it credit for. Most “hollywood” glass is actually panes of sugar. You could certainly arrange things so that the gun’s pressure wave has a good chance of stressing and breaking glass, but it would take special preparations and effort and the gun would probably have to be very close to the glass. It’s almost unheard of for it to happen normally unless you specifically shoot at the glass.

Someone like mythbusters could probably test this pretty effectively, but based on my experience around guns and glass, I suspect they’d come to the same conclusion.

A not directly related but still interesting video was done by the slowmo guys on youtube

It’s veeeeery not standard in Canada. I use it on my phone and most people who see it on the lockscreen treat me like I’m an alien, and it’s about a 50/50 mix of people who simply think 24 hour time is weird (but at least recognize it) vs. people who seem genuinely baffled by the digits they see appearing on my phone and don’t even seem to recognize it as a time at all.

No good reason, just historical inertia and resistance to change. People stick to what they’re familiar with, either the imperial system or to common metric units. Making a “metric ton” similar in size to an “imperial ton” arguably helped make it easier for some people to transition to metric.

Megagram is a perfectly cromulent unit, just like “cromulent” is a perfectly cromulent word, but people still don’t use it very often. That’s just how language works. People use the words they prefer, and those words become common. Maybe if you start describing things in megagrams other people will also start doing it and it will become a common part of the language. Language is organic like that, there isn’t anyone making decisions on its behalf, although some people and organizations try.

I don’t think they know about metric prefixes, Pip.

Imagine if the marketing people discovered that they could advertise that it has 19 million uWh (in Doctor Evil voice). Don’t say it too loudly though, someone at Apple might hear.

If you can prove beyond any reasonable doubt that someone is ignorant of facts, and then sure you can call it obvious and good. But when nobody can agree what is reasonable, why is your perspective of good the one everyone must follow? It’s not always obvious. Don’t pretend it is. And things that are reasonable and obvious to you aren’t necessarily reasonable and obvious to others. You aren’t willing to embrace the diversity of human experience and opinion, so you won’t get the benefits of that diversity. Just because someone else has a different idea doesn’t make it wrong. If you think literally every idea that isn’t exactly the same as yours is wrong, then we’re wasting our time here anyway.

So again, why is your path the one we’re picking? Even if I do agree with it, I am not willing to agree to it blindly, I want to know why we’re supposed to follow your advice/instructions/demands. At gunpoint or otherwise. And that’s why I’ll never follow a totalitarian, because totalitarians never have to explain themselves, and generally won’t. I hope you brought enough bullets if that’s your plan.

Musk is the richest man on Earth, give or take a few billion here or there. He can keep it running as long as he wants. It’s nothing but a toy to him. The problem will start when he finally gets bored of it, because he has already broken it to the point that nobody else will want it. He has killed it, it’s just not dead yet as long as he keeps swinging it around and paying its bills. But one day he’ll stop doing that, maybe once he finds a new, shinier toy. We just don’t know when.

Does the change in gravity gradient across your body kill you right now? No? You are currently orbiting the supermassive black hole in the center of the milky way.

It was implied by “accretion disc” and by the fact that we’re talking about gravitational gradients at all that we’re talking about a close orbit. Gravitational strength gets smaller with distance according to the inverse square law, so by the time you’re a few light years out from the galactic core the gravitational gradient is already extremely insignificant.

brb replacing all my bodily fluids with LSD, will let you know how it goes

I’d argue against that. For one thing it is impossible to imagine a situation where there is no change in the gravitational gradient across your body over time. Your orbiting a black hole situation is a perfect example of a situation where the gradient alone would tear you apart. The conditions you’ve specified are tautological. There’s no way to maintain a zero gravitational gradient while also simultaneously having extremely high gravitational field. The two are mutually exclusive in any conceivable scenario.

It’s like saying a human being in a hypersonic wind stream won’t necessarily hurt you, burn you alive and rip you to pieces (not necessarily in that order) as long as there is no turbulence and you have a sufficient boundary layer – but you’re a non-aerodynamic human body in a hypersonic wind stream, so of course there will be turbulence and the boundary layer will not protect you at all, you’re going to die, basically instantly.

Call the local fire department non-emergency number and ask if they can schedule a visit to inspect your fire alarms and provide recommendations on the situation. The fire department is genuinely interested in your safety, because it’s also important for their safety so they don’t have to come rescue you. If anything is a fire hazard, the professionals can explain why and explain how to fix it. But they’ll probably say “WTF” because the landlord is most likely just being a fuckface, as landlords do. Assuming the latter, ask them if you get the “WTF” in writing so you can wave it in the landlord’s face when you tell them to fuck off and die.
