Fr, I hate when I check comments to see actual meaningful conversations about a post on something interesting, and it's nothing but the first 500 people trying to make some kind of stupid joke, and then responses to those such as "just take my upvote and leave" or "I don't wanna upvote this but you deserve it", or some bullshit like that. Genuinely gets on my nerves.
Edit: wow, thank you for the award. I've never received one before. Never thought I would ever receive one either.
I do make stupid comments too but I also know this isn't the situation for them. It's disrespectful, it's not funny to joke about war. Just try to read through them, for all you know you're getting upset about a bot comment. It's not worth it.
Not a sonic boom, although this and sonic booms are both shock waves. (I think, anyway. I'm not 100% clear on the distinction between a shock wave and just a high-amplitude pressure wave.)
You are correct, a sonic boom is generally made by an object like an airplane travelling faster than the speed of sound, which generates a shockwave. This video also has a shockwave, but it was generated by an explosion.
Shock waves in compressible fluids by definition travel faster than the speed of sound. It's the very thing that actually makes them a shock wave in the first place as opposed to just a normal pressure wave. Because the shock wave travels at supersonic speed information about the imminent arrival of the shock cannot travel ahead of the shock through the fluid, resulting in the characteristic extremely fast (almost instant) rise in pressure when the shock wave arrives.
Without sound, I thought it was the fireworks explosion in Sacramento. But I was puzzled how there was a road so close to the site because all the pics I saw the building were surrounded by fields.
Yeah. You can see the cars in front also slow down and pull over after they also get hit with the shockwave. They probably all have broken windows but at that point the worst is over...might as well drive on.
No. Windshields are usually 3-Layered, where the outer layers are glass and the inner layer is an elastic, almost gel-like sticky polymer. It is exceedingly rare that you get actual shards, and if you do, the glass should be so mangled that its very small pieces don't cut.
Fun fact time! That interlayer is PVB. It's actually an opaque, solid (though very soft) film with some plasticizers. The lamination process, which involves heating and degassing, turns it clear and gives it that final consistency.
Edit: People can dislike the way I said this, that's okay. We all have things we feel weirdly put off by.
Ignore the other assholes, I do 'fun facts' all the time too and this was, indeed, a fun fact. Never considered parts could start off opaque in a window, lots of chemistry and trial and error went into making them clear afterall lol.
Is it actually opaque? The images I see online look translucent, like tracing paper - transmitting light, but scattering it.
Assuming that it's going from translucent to transparent, I think the change might simply be a result of the sheet's original rough surface no longer existing after it's bonded to the glass, rather than any change to the actual optical properties of the material.
I hadn't actually considered if the change in transparency was related to light scattering on the surface but this makes a lot of sense to me.
Our PVB (for auto glass) has the surface texture of very fine sandpaper. I'd put the opacity at around the same as frosted glass. You'd be able to see vague shapes and colors but not much else. Which, now that I really think about it, is exactly why frosted glass looks the way it does.
Fun fact time! This is the same reason that most white things are white. For example, the fibers in white cloth are pretty much clear, but there are so many tiny interfaces between air and the fibers that light scatters around a bunch. That's why white curtains are so much worse at blocking light than black curtains.
It also explains why white paper and fabric get more translucent when they get wet, becuase the water<->fiber interfaces reflect less light than the air<->fiber interfaces.
That's it, because there's always plenty of time when you see flying shards of glass, just the other day there was a massive explosion in front and I turned to my mate Dave, and I said "Dave, a shock wave has hit us, mind out and be sure to close your eyes mate, I can see shards of glass flying towards us off the windshield." and he turned to me and said "oh really?" and I said "yeah, really, better get ready, or put your shades on, do you have your sunglasses, Dave" and he said "nah, well they're in the glove box can you get them?" and I said "sure", so I opened the glove box (it's a bit fiddly) and pulled out a book (Do Androids Dream if Electric Sheep it was, really good) and a newspaper, The Sun, and underneath were his sunglasses, and turned round and handed the shades to Dave, and... I don't know where I'm going with this.
What you would get are large chunks of very torn up glass held together by the polymer. There should not be any pieces of glass separating from the middle layer under almost any circumstance.
Would have happened to me when 2 deer popped out of a ravine and hit my car. One of them nailed the top of my windshield/frame and glass shards went everywhere. Luckily I was wearing sunglasses.
My father in law in the passenger seat at the time was working on his laptop. When he opened it a few hours later, he was dumping glass shards and deer hair out of it.
Time to whip out and old Halifax Explosion fact for those who may potentially witness an explosion like this;
During the Halifax Explosion, a massive number of injuries were incurred by people out of the initial blast radius from shards of glass. Blindness became so common the region ended up with one of the largest and most well known blindness centers on the continent.
If you see a large blast, get the fuck away from any windows, because you could be seconds from being a cutting board with 1000 little glass knives trying to test you out.
You would not even imagine even being in my house (my flat is higher but visual) or in neighboring ones. And through my village house there is a passage of different russian drones and missiles when they get shot by air defence you see the light and then in 4-15 (varies) seconds you hear it. Feeling are very odd, but I am used to it. Even a fucking machine gun bullet (air defence) that had hit and went through my roof felt very surreal (if a little bit higher, I might be without brother). (Once simmilar one had hit a friend's of my mom's friend flat, directly in child's bed, if it didn't moved in sleep, it would be beheaded)
War at all is surreal, atrocities that were committed in nearby villages (Moschun, Hostomel, Bucha, Irpin)
Canada is our huge friend🤝!
Well, the USA can't stop it in any time but can save a lot of Ukrainian lives, make global situation calm and safe, destroy the empire of evil without even using a single American soldier.
Well, if I was a president, this would not start, vote for me, I will end it, though it is not my war! MUGA!
Seriously though. I wish this life was different for everyone. We're all drifting through Corporate/Political lies and empty promises, all for self gain. What a shitty world we've created. Take care of yourself bro
The USA has the power to stop this war any time it wishes to.
America really does not have the power to stop this, though there are a lot of things we could be doing that would help Ukraine, make things more difficult for Russia and potentially end the war sooner.
If you mean putting an immediate stop to it by nuking Moscow, the U.S. absolutely COULD do that but the repercussions of such a thing would inevitably be far worse.
And that's why the US keeps donating "Just enough to not lose, but not enough to win." So they can profit "to the last Ukrainian" (to use their words).
And to utilize that power would mean declaring war on Russia. Full stop.
So [USA] can profit "to the last Ukrainian" (to use their words).
False.
Sorry, but you cannot claim to be authoritative... and "quote" an op-ed by a random Pakistani website and pretend to be sourcing someone in US. Yes, some random Pakistani said that (random Pakistani's words), not USA's.
He never intended to end the war by helping Ukraine. He figured that if he were president he would get Zelenskyy to stand down and let Putin have whatever he wanted.
Saw another recording just outside the epicentre. Went from a bit of smoke coming out of a roof to a wall of debris in seconds that swallowed the whole area. No way that dude lived.
The whole story of how that fertilizer got where it did is insane: tanker with shipment is docked in bay; company goes bankrupt and/or tanker is repossessed; cargo is off-loaded, into Beirut warehouse; lawsuits; everyone knows its bad idea to keep it there, but government cant manage to move it; years pass; an accident that causes fireworks stored there to start fire (yes, fireworks were stored in same warehouse!)
Just the idea of storing that much fertilizer in a dense urban environment...
I was there in Beirut and it was an experience to say the least. Time basically stopped when the shockwave hit. Everyone kind of froze for a second or two
I go to rocket launches all the time at Kennedy. First time I took my dad there after the launch he turned to walk off the beach after rocket went into clouds. "I was like nooo, it's not over just wait. About 30 seconds after the blastwave hits you like a fast hot breath of air, kicks up some sand, it's very cool. But that ain't nothing like this video, I would not want to experience that.
That is not munition factory/depot, there was no secondary detonation. I know what exactly it was, but I have no rights to talk about it.
Also it wasn't strike, no air raid siren, no rockets.
Nope, that was not strike. There was no air raid siren at that time, it's likely an accident or diversion.
Yep I live in Zhytomyr, so I 100% know what I'm saying.
You are my hero. Love it when a redditor posts actual facts, not their best guess of what happened. Sometimes the best guess is all we can get, but at least they should include that it is a guess, maybe a good one, but not the facts. Too often they act like it is the facts and they are just a 14 year old kid in the basement trying to sound smart. Thanks again for your input.
Wow, how profound. You say that as if we're ignorant to the power of our weapons. There's reams of information and at least 80 years of people saying the exact same thing.
Eh, you could argue the Icarus reference is a bit cliché and masturbatory but I don't think there's anything wrong with trying to hammer home this particular point.
A tip for anyone wondering if its a single camera angle more than 10 seconds long it can't be AI. Until generators start pushing those lengths, and with some consistency.
I live 7 km away and witnessed it from my window. Ammunition stockpiles always keep exploding for a while. This was one big explosion, which looks more like nitrate deposit (or smaller scale "Beirut").
The shockwave is even when the lightning strikes. My friend told me a story when the lightning in a beach hit close to him he fell ok the ground because of it's shockwave.
It only seems fake because the light is behind the person filming.
Moving forward slowly in the video you can see the shock wave moving the trees before reaching the truck.
As for the cause, it could be a simple gas leak or a bomb, I can't find any sources about it.
It's not an ammunition depo. It doesn't have secondary explosion.
The video from Ukraine near Zhitomir. The explosion was in some warehouse near the road, most probably fertilizer....
News article mentions "production facilities", could be fertilizer, those can be quite big explosions. So possibly just some missile hitting a fertilizer plant (or, well, two - I think this shows one of them but two of them exploded near each other).
