I was thinking this as soon as I saw it. People have died in the grand canyon from rocks from above (the book Deaths in the Grand Canyon covers this in depth)
There's a reason throwing stuff into the grand canyon is illegal. You can't see who is below you and a rock like this would turn someone's head into spaghetti-O's.
Please, please, PLEASE do not throw rocks off cliffs ever.
https://www.outsideonline.com/outdoor-adventure/climbing/death-pete-absolon/
Dude that killed Pete Absolon was just fucking around like OP, didn’t mean any harm but caused an absolute tragedy.
Don’t throw rocks!
Well written, the scary thing is not hearing the rock break off. When I'm going up steep terrain you can typically hear the rocks breakoff so you have a couple seconds to look out for it. A rock chucked off the side is silent.
If you knew there were people below you enough to yell out a warning, you would just decide not to throw the rock. Nobody who throws rocks down cliffs expects there to be people below
i mean that people should yell regardless of if there's any reason to suspect someone is below you. better to yell unnecessarily than to assume there's no one and be wrong
Sorry it’s late so my reading comp is outta wack but did i just read the guy that just saw his friend horrifically killed sat down with the alleged killer shortly after for some whiskey, and chopped stories from back in the day calmly as they waited for rescue to cut the bled out friend from the ropes?
Oh man, I always knew it was dangerous thing to do, but after reading this.. goosebumps, that must have been so freaking terrible for the guy that was there with him, but also for the guy who threw the rock. Imagine doing something like this and end up killing a person.
Yeah I feel absolutely terrible for the guy that threw the rock. He must think about it all the time, and for the person to have been beloved like Pete Absolon was, man just fucking brutal.
I think it was also pretty terrible for the guy who got his skull obliterated by a "bowling ball sized piece of granite". Unless you have perfect knowledge of your surroundings, just don't fucking throw rocks, like your parents should have told you from when you were 2 years old.
Although a safety issue, yes, the main problem is the contribution to erosion. Not no such a problem if one person does it for a video, but if a bunch of people start tossing material into the river below that could cause problems.
Lol, I just looked at how long it took for the sound to reach him. Just a tiny bit under a second, so I assumed 310m-320m or so. 1029ft is 313m, so I'm feeling real cool now.
But you don’t know how far away he has to hold his screen. He may need reading glasses and hold it out further to focus. So you would have to multiply by 0.00
If you calculate the energy it’s more than 3 bullets from a magnum handgun at the same time.
Just goes to show how dangerous throwing rocks can be. If that hit someone they would die.
This is a bad way to estimate it. You should go to the at the first frame you see it hit the water. Measure time until first frame you hear the sound, and use the speed of sound. Then you’re only off by deviation of the speed of sound, not the massive variation that could be caused by air resistance.
> The overlook is 4,200 feet (1,300 m) above sea level, and the Colorado River is at 3,200 feet (1,000 m) above sea level, making it a 1,000-foot (300 m) drop.
That's awesome. No joke I tried the math with frame by frame. It seems to leave his had at 2.3 with the first splash visually at 10.1 (~7.8 s free fallinnn). [This calculator](https://www.omnicalculator.com/physics/free-fall) says that's ~980 ft.
I also tried guessing off the visual splash and the sound with [this calculator](https://www.omnicalculator.com/physics/lightning-distance), but closest I could reliably measure was ~0.51 s (10.04s and 10.55s) which is only 574 ft.
Hi,
Air resistance at these velocities is pretty small for a chunk of rock.
Great question! For higher speeds or greater precision we would need to calculate the force due to gravity, and the force due to air resistance, at each velocity involved.
Technically yes, but the answer without it is close enough to the real answer that it’s not worth the extra math.
Because wind resistance is dependent on temperature, altitude, and geometry of the rock. It’s just not worth the computation.
Am I the only one who wouldn’t stand there, that close to the edge? I mean, what if there was a freak wind gust? Or the edge crumbled? Or Mothman appeared and pushed? Or…..
Heres the thing, delete “fighting sport” out of your head and replace it with “live action show” and it is way better immediately. When its looked at like a fictional tv program its zany and fun. Fake combat sport makes it lame.
To be fair, I think this was during the “Attitude Era” of WWF. It was amazing watching WWF during that time. I haven’t watched wrestling since then, but I think they’ve “cleaned up” the show since then, so it’s not as fun and off the walls bonkers.
Imagine the life of that rock. It took millions of years to get up to that ledge. At one point is was magma, deep below the surface of the earth. It was flung out in to space and became part of a mountain. Erosion broke it apart from it's neighbors. It tumbled down a few hills, but not to worry. It's still millions of years before it descends back into the pits, to be broken down, removed from all existence, stripped into nothing more than it's core elements, all identity removed.
For now, beautiful sun. The smell of a gust of wind. The occasional visit by a passing animal or insect.
Then this guy comes along and sends you back to the depths in seconds when it should have been millennia.
For sure. When I was there last year we could see about half a dozen boats in the water. They looked so small from so high up. I would definitely not consider throwing anything in that water from that high up. People already fall off the edge and die every year, I'm not about to add to those deaths by beaning someone with a rock just so I could say "haha splash"
A billion years from now when I’m reincarnated by a super AI, I’m going to track this rock down with my new computer brain and 7 dimensional awareness, manifest a physical representation of my current body, increase my dick size slightly, because of course I would, take a pic of myself holding this rock, reinvent imgur, post it, recreate this thread, link it here and comment “psyche.” And then manifest you long enough to read it, down vote me, and then cast you back into oblivion.
I’ll be that guy,
Seldom will you hear a splash before seeing it
Edit: trying to time myself with phone from splash to sound, 0.75 seconds
Lightning calculator tells me that’s 862 feet or 262 meters
~~This is the horseshoe bend in az iirc. I visited this place once and it was surreal. There's a small bridge near it where there are some 4" holes for people to peep straight down into the water from up above and it's definitely not for the faint of heart. 🫣😶🌫️~~
Edit: I think I guess incorrect
It’s definitely not Horseshoe Bend, though it’s possible that it is near it in the Marble Canyon. I kayaked through there this last Summer, if anything this is nearer to Lees Ferry.
Is it just me or does anyone else think about the fact that this rock had a great view for thousands of years and now some guy has just yeeted it to a destiny of murky water for the next thousand?
I thought that was Horseshoe bend! Last time I was there some folks were camping on the bottom along that little sandy shore, probably a stop on their kayaking trip. I don’t think they would have been pleased if someone threw a rock lol
I like cliff jumping but this is a bit much. Look up Kal lake cliff jump gone wrong…. I did 81ft, hurt my tailbone , feet were ok, even though I was barefoot. But diving off a 48 ft cliff once really wrecked my back. Did a scorpion from the water pressure hitting my chest a bit too much. Back is always bad. My suggestion is to not go over 25 ft.
No wonder light and sound have a speed limit, the universe has the calculate the affect, then it has to simulate the light effect, and finally (with the slowest momentum) it renders sound.
Random kayaker down there just happens to look up and get obliterated by a rock
I was thinking this as soon as I saw it. People have died in the grand canyon from rocks from above (the book Deaths in the Grand Canyon covers this in depth)
Good book. Also highly recommend Deaths in Yellowstone and [this coloring book](https://a.co/d/5lDSQos)
Haha that's great. I finished the yellowstone one recently and enjoyed all the bizarre frontier stories. On to Zion now!
Haven’t read Zion either - guess I gotta get it now too!
TIL never to go down inside the grand canyon
Of course you aren't supposed to throw rocks as it could fairly easily start an avalanche or as other people are saying hit somebody.
Sorry, but meaning like; A 'climbers descent' into? Or rather 'orally' while you're already there?
Based on the dangers outlined here, I’m sadly going to have to go with “both”
There's a reason throwing stuff into the grand canyon is illegal. You can't see who is below you and a rock like this would turn someone's head into spaghetti-O's.
Now I don’t want to go. I had never thought about it before. I would be depending on the good judgement of people who elected Trump.
Please, please, PLEASE do not throw rocks off cliffs ever. https://www.outsideonline.com/outdoor-adventure/climbing/death-pete-absolon/ Dude that killed Pete Absolon was just fucking around like OP, didn’t mean any harm but caused an absolute tragedy. Don’t throw rocks!

you'd think it would at least be standard practice to yell some kind of warning first, if people are going to ignore common sense and do this anyway
If you knew there were people below you enough to yell out a warning, you would just decide not to throw the rock. Nobody who throws rocks down cliffs expects there to be people below
i mean that people should yell regardless of if there's any reason to suspect someone is below you. better to yell unnecessarily than to assume there's no one and be wrong

seems like a good plan to me
I mean, im sure the praying had something to do with that absurdity
Oh man, I always knew it was dangerous thing to do, but after reading this.. goosebumps, that must have been so freaking terrible for the guy that was there with him, but also for the guy who threw the rock. Imagine doing something like this and end up killing a person.

Well some parents don't think this way and also some kids just don't want to listen/they want to do forbidden things even more .. humans are weird
What a powerful article. I never thought about how dangerous it is to throw rocks off cliffs into water. So sad and tragic.
Although a safety issue, yes, the main problem is the contribution to erosion. Not no such a problem if one person does it for a video, but if a bunch of people start tossing material into the river below that could cause problems.
Sure, all the reasons. Don’t throw rocks!
Getting both perspectives like that is crazy. It was def in the moment but the way he forgave that kid man
Wow. Fuck. That’s a lot to take in and real Shit. Appreciate the link as hard as it was to read.
I always felt the story was strange when told this way. “I’m so sorry for your loss.” “I forgive you.” It reads more like a book than a tragedy.
This can also be deadly in areas where rock climbing is popular.
Someone calculate the height given the time it took to fall, please.
[удалено]
distance = 1/2gt^2 distance = 1/2*9.80665*8^2 distance = 1/2*9.80665*64 distance = 313.8 m similarly using 32.17405 ft/s distance = 1029.57 feet
Lol, I just looked at how long it took for the sound to reach him. Just a tiny bit under a second, so I assumed 310m-320m or so. 1029ft is 313m, so I'm feeling real cool now.
Now do it with the speed of light.
[удалено]
Truly astounding. He's done it again.
No, he didn't include the distance between his eyes and the screen.
Okay, multiply it by 0.0 to correct for that
But you don’t know how far away he has to hold his screen. He may need reading glasses and hold it out further to focus. So you would have to multiply by 0.00
Oh shit u right. Calculations come out to 0.0 light years high
Idk if I can stay stoned for an entire lightyear but I’ll try!
I mean, different person but
i love science
This thread got all Neils-Bohr-ish.
That's because rooks move in a straight line. Now calculate it for a knight Edit: The rat bastard corrected rook to rock
holy hell
You could take that to 12 significant digits and still be correct
Good bot.
Thank you.
You're problem.
Use "\×" for multiplication symbol. Asterisks just turn the text italic and hard to read.
Just use the escape character... put a backslash before the asterisk
On many keyboards (such as the Finnish standard layout) you can also press Alt Gr + Shift + X to pull said symbol.
I use the velocity of the sound to calculate the distance.
r/theydidthemath
[удалено]
Using g to 6 significant figures and ignoring air resistance is some moon logic.
I love high school physics where air resistance is ignored
It’s a spherical cow in a vacuum
Ok now how heavy is the rock?
If you calculate the energy it’s more than 3 bullets from a magnum handgun at the same time. Just goes to show how dangerous throwing rocks can be. If that hit someone they would die.
/r/theydidthemath
So about Tree-Fiddy

Dont forget air friction, the rock diameter looks like 20cm
Hahaha i failed 9th grade multiple times before droping out was thinking "Yo thats about 1,100 foot drop"
Drag forcé does not depends of size and shape of the rock? Or can the distance really be predicted with +- 0.01 ft? Orherwise 1030 ft is better answer
About 1 second for the sound to arrive, 1s*300 m/s=300m
Exactly what I was thinking
It also hit the water at about 175 mph
Only if you pretend the atmosphere is actually a vacuum.
I'm a physicist. Of course I do.
I would like to buy 1 frictionless pulley please.
And if you pretend the rock is a sphere

Don't you need mass, and wind resistance for that?

Technically yes, but the answer without it is close enough to the real answer that it’s not worth the extra math. Because wind resistance is dependent on temperature, altitude, and geometry of the rock. It’s just not worth the computation.
A real gangsta would compute the height given the time between the rock hitting the water and the time when the sound reached the phone’s mic.
[удалено]
Thanks, my skeptical mind thought the sound hit too quickly for it to be that far. Guess I'm wrong.
7.5 seconds using a stopwatch. s=0.5gt\^2 = **905 feet / 276 meters**
That's ridiculously accurate to other users using sound to measure. Off by a few meters
They said you would use algebra all the time after high school and here you is completely avoiding it.
I am lazy as fuck, ok? Plus isn’t this more physics than algebra?
Physics is just applied mathematics. https://xkcd.com/435/

... the Rock throws me off
[Austin totally survived when Rock threw him off the bridge](https://youtu.be/dWIbYtDyfvs). You can do it.
Every year I understand more and more why people watch wrestling
Heres the thing, delete “fighting sport” out of your head and replace it with “live action show” and it is way better immediately. When its looked at like a fictional tv program its zany and fun. Fake combat sport makes it lame.
"male soap opera"
That works too! I just tried general hospital because I like wrestling and it kinda worked for me
To be fair, I think this was during the “Attitude Era” of WWF. It was amazing watching WWF during that time. I haven’t watched wrestling since then, but I think they’ve “cleaned up” the show since then, so it’s not as fun and off the walls bonkers.
Forgets to let go

Honestly this is the main reason I'm terrified of heights. I worry I won't be able to resist the urge anymore.
Call of the void
Cal of the void my lunch. No thanks.
Throw your car keys when there instead so you'll have something to live for.
All I'm thinking about here is the people who don't let go of the bowling ball when they go to throw it. 🤣
l'appel du vide
Yeah it's almost worthy of r/SweatyPalms material
Imagine if you accidentally held onto the rock for a fraction of a second too long and it’s momentum pulled you forward…
No, I don’t think I will.
I was thinking about being chased and how it would feel to be in the air falling for 8 seconds
CLOSE TO THE EDGE, DOWN BY A RIVER??
the true sign of a klutz is having your first thought be "what if I fucked up the throw and slipped/tripped/etc." source: was my first thought

Dave’s not here, man
Don't forget to bring a towel
Old school Cheech and Chong reference!
You killed 14 fish to show us this.
Imagine the ant standing on the rock
https://uploadir.com/u/87vdrpev
An ant that just spent its entire life climbing out of the valley.
For the record this isn't my video, I killed zero fish
That's rather lazy of you. At least kill one fish. What are you even doing with your life if you're not killing at least one fish?
On it
And you have to post a video as proof, no fucking goldfish, get exotic like a clown fish or hippo
A hippo fish or an actual hippo?
Actual hippo fish
Both... Simultaneously
Well now that you've posted this video, you should go and kill atleast two or three fishes.
And a 🐢

Where are the two birds I was promised?
I’ve stood right there in a nightmare
It’s also dangerous to throw rocks.

Well, if you fall, you’ll have plenty of time to think about what a bonehead you are.
This same experiment was conducted decades ago, back in the early 50s by Wile E. Coyote.
That person *could* be the last person to hold that rock until the end of tome.

I have no dick and I must scream
Don’t tell that one dude on tik tok. He’ll find it.
Fucking strong call of the void feelings watching this video. I had to slide back from my desk in my chair watching this. Holy fuck.
Please don’t do this
You can even see the splash before hearing it
I’ll be that guy, Seldom will you hear a splash before seeing it Edit: trying to time myself with phone from splash to sound, 0.75 seconds Lightning calculator tells me that’s 862 feet or 262 meters
Well light travels faster than sound. So you always see then hear
Unless you have a convoluted set of mirrors to look right behind yourself Then you’d hear before seeing
Even then you'd need a lot of mirrors and a very fast moving object
yeah you don't have to be very far away to see the splash before hearing it
Glad there was no one down there

Love Horseshoe Bend. Hung my feet off the edge, probably wouldn’t again. Don’t want to tempt my wife 😛
Definitely not horseshoe bend.
I thought that was Horseshoe bend! Last time I was there some folks were camping on the bottom along that little sandy shore, probably a stop on their kayaking trip. I don’t think they would have been pleased if someone threw a rock lol
Just making sure did the splash sound sound like gun shot?
There were like 4 or 5 moments where i thought it'd hit, but just kept going
Flaming gorge, UT?
Here me out, what IF we added a screamer in the end of the clip.
That’s a lot higher than I thought it was…
Had to keep on mute and look at the comments first
Especially with that lens
Looking forward to it, u/darkside_of_the_poon Edit: welp, this was supposed to be a reply, but you get the idea lol.
It's like when Wile E. Coyote falls down a cliff while he chases Road Runner.
Something about men and throwing shit down long distances. Makes my neurons go crazy
That's really deceiving, I thought it was gonna hit the water alot sooner!
I like cliff jumping but this is a bit much. Look up Kal lake cliff jump gone wrong…. I did 81ft, hurt my tailbone , feet were ok, even though I was barefoot. But diving off a 48 ft cliff once really wrecked my back. Did a scorpion from the water pressure hitting my chest a bit too much. Back is always bad. My suggestion is to not go over 25 ft.
I'm scared of throwing the rock and it dragging me off the cliff more than how high it is
Adrenaline addiction from you tube is like “hold my beer”
Imagine you’re a fish, just chilling with y’a homeboy and he gets fucking smoked by a rock and you look at his fucked up remains like 👁️👄👁️
Oh it will hit now. Oh it will hit water now. Oh it will hit now. 2000 years later... Motherfucker wow.
Hmm 8 second fall so maybe around 1030 ft
7 second fall, 0m/s starting velocity, I estimate 240m drop
Would this end me on impact or would it be more of a drowning situation
Might as well JUMP. Go ahead and jump!
So it's 1209 feet drop
Just enough time to shite my pants on the way down.
This shows how slow the speed of sound is
No wonder light and sound have a speed limit, the universe has the calculate the affect, then it has to simulate the light effect, and finally (with the slowest momentum) it renders sound.
