"Y'alll are wimps. I'n my day mountains were taller! " 😂😂😂1
“And time moved faster for us at two feet higher, so we always got more done in the same General Relativ(ity) amount of time as you take now!” 👵🏼👴🏻
I dunno, man. I’m in Colorado now, and I’m pretty high.
🤣
Duuuuuuude....
whoooa
🫡👌🏽
Im in Victoria Canada, my body may be at sea level.... 🌳🌳🔥🔥💨💨💨
Climb a 14'er easier than ever before, with one simple trick mountain guides don't want you to know!
This isn't true, I actually saw a guy at the tops of the mountains with a big hacksaw
Change is the only constant
For cities and towns it was only arbitrary anyway depending on where the elevation was established.
Also, cities are not completely flat, there are hills and valleys in them just like anywhere else, so not all of a city is at the same elevation.
Usually at the town hall or courthouse. Woodland Park, where my daughter lives, has two very different elevations on US 24!
@@russlehman2070 People are prone to forget that HALF of Colorado is essentially flat. Certainly compared to anything west of the Front Range.
my grandfathers best friend steve did a lot of the origginal topographic maps of the 1950s
Now this is news worthy… for about a few hundred of us 😂
For anyone curious, the (fantastic) podcast Let's Learn Everything has a segment about the tallest points on earth (there are two depending on how you define it) and it goes into the sea level concept in-depth, basically it's a really great detailed expansion on what this video introduces. Highly recommend that segment and the pod in general! It's always a hilarious and fascinating time lol
Edit: For anyone planning to look up this podcast segment, I checked and it's in episode 39!
Thank you, I was wondering more about what this is all about and how it works and why.
@@babybirdhome Right on, I'm so glad my comment has reached people who are curious! I just looked at the LLE episode list to find the specific one, and it's episode 39: The Pill, The 2 Highest Points on Earth, and Period Products. (They used to do three topics per episode but recently changed to just two.) They're really fun science communicators lol, I hope you get to check it out!
Not sure I understand why elevation has anything to do with gravity. For layman like me, elevation above sea level means vertical difference between actual sea level (say in Florida) up to top of a 14er, not between the imagined sea level under the mountain and the top of the mountain
The closer you are to an object (Earth's center), the greater the pull of gravity. That is why objects dropped above the Earth fall with an acceleration, not a constant velocity.
As for the part about the mountain, I'm not sure what the point of it is. They are re-setting the standard with something that seems imaginary but I don't know why and how it is being done.
If you're in Colorado, do you use the sea level in Florida or California? Based on what they're saying, the sea level in those places would be a bit different due to the topography, so it's more accurate to come up with a 'local sea level' that accounts for the topography at any point.
Base it on sea level at the same latitude as that point in colorado.@@masonlewis5491
What do you mean when you say "vertical difference"?
This is the core of the problem that is hard for most people to understand (I'm a field surveyor)
If Earth were a flat plane, what you're saying would make sense. But we all know Earth isn't a flat plane, and we have to account for that somehow. That's what the ellipsoid model he mentioned in the video is for, to account for the odd shape of the earth when measuring elevation. "Sea Level" doesn't exist in Colorado, so we can't just measure straight up from there. Earth isn't a perfect sphere and has an irregular shape, so simply carrying relative elevation from physical sea level is going to be inaccurate for a number of reasons.
Honestly it's amazing that they were *only* off by about two feet in most places given that they weren't using any digital equipment like we use now.
It really is incredible how close they were.
Rocky Mountains apparently grow an inch every decade. So in a few hundred years, all the plaques will be correct again.
the explanation in this video is incomprehensible
This "height above ellipsoid" standard is going to be very useful for 9-1-1 technologies when determining cellphone caller locations.
Does water boil more accurately now? I would think that the boiling point would have been off if the altitude was incorrect.
Lol
Barometric pressure is always changing.
This is the new sea level. It doesn't matter if there is water there or not. It's easier.
This just seems more complicated and difficult to me.
@@adamofblastworks1517 The more complicated they make it, the easier for them to gaslight us. If they tell us this is sea level and we can see there is no water there and there has never been water there and we still believe them, then it's on us for being easily led sheep.
@@adamofblastworks1517 It's easier to determine the height this way if you use a GPS machine. And 99% of people will use GPS.
@@letsburn00 why is it easier this way for GPS?
@@adamofblastworks1517 Did you watch the video? GPS operates using a non spherical earth reference frame to account for the whole earth. The original sea level reference frame is based on a "true" frame vs the sea. But given gravity is relevant here, that applies.
The real story they aren't saying is that GPS is extremely tightly defined using gravity because it was designed to aim nuclear missiles. This aligns the geodesic to GPS, since it's more commonly used than guys with sticks
What happens when sea level rises? Falls? Maybe we should just pick a point, call it 0ft. and go from there... quit worrying about the inconsistency of water levels!
My understanding from this is that the real sea level doesn’t matter. It’s the height above the ellipsoid plus the difference between the force of gravity and the ellipsoid. Did I get that right?
If you watch the video, they are removing water level from the formula.
@@TeachAManToAngle Gravity is an acceleration, NOT a force... so who knows what they are doing!
@@kc0itf The last I heard, gravity is still one of the 4 fundamental forces, which include, electromagnetism, the weak nuclear force, and the strong nuclear force. Acceleration is related to the intensity of the gravity.
Exactly. NAVD88 is an orthometric height system based on 1 single point.
And the Pacific Ocean and Atlantic Ocean aren’t the same height. Mean Sea Level is not a datum. As sea level varies by latitude and tidal forces. MSL is local which is why marine charts have MLLW specific to a given port.
Who’s going to update all the charts & data pilots use?
thanks!! feels the same, though.
Yeah they’re constantly eroding, hence the rocky features in the rocky mountains.
Seems like not having the same fixed distance for every height your not actually measuring elevation. Why not measure the height at a specific location to something in space or maybe compare the local gravity to zero gravities?
It sounds like the heights weren't wrong, the sea level was wrong. Regardless, it seems like height above ellipsoid is a more useful measurement than height above sea level.
More useful to whom? For what?
@@ninjalectualx I would say it's more useful for almost any kind of survey. Your altitude number shouldn't change just because ground water changes. You can figure out your height above ellipsoid easily because it's just your GPS coordinates.
Just wait until the planet Nibiru flies nearby. The deformations in the crust from the tidal forces will make all this work for naught😉
BILLY JOEL JUST REAFFIRMED ROCKY MT HIGH.
Don’t we have satellites that measure stuff down to the centimeter? I think with the ocean they have 10cm wave height info.
This guy is so proud of this discovery.
Just extend the poles by two feet it'll be cheaper
" Depending on how you count, ten times more accurate..." So in other words , it depends. Thus, none of this is settled even now?
Colorado has bad gravity.
It's a "dry" gravity.
So is the Geological Service going to change all the plaques on each 14ers.
No, the money for that project went to Ukraine.
@@samrichardson2641
Lol you're adorable. Bless your heart. 😊
@samrichardson2641 Israel*
I don't recall seeing government plaques on fourteeners.
Very cool
First pass estimate plus or minus 10%. 'About' 14,000 ft
Heck, those mountains ain't even worth climbing now.
What does this achieve?
Nothing, it just gives them a job to do. Otherwise, they're just playing cards.
@@stevegabbert9626 likely.
Turns out, accurate survey data is REALLY important for tons of different industries. Construction, mining, and forestry are the big ones I've encountered.
sea level is the top of the liquid part of Earth's atmosphere, should measure from the lowest point of Earth's rocky crust.
Might be flat wrong
Does this mean you'll finally adopt the "Metric" system as well?
Don’t be daft man!
@@JohnSmith-gb5vg Cubits and furlongs it is then.😅
No way, man!
Nope. We're keeping our banana-washing machine-football field method!
colorado government is more worried about money than anything...
What is a 14er?
Nevermind, the video answered my question. 😂
Maybe. If You don't know: Urban Dictionary.
@@TheJustinJ no. bad. no treats.
He works for the USGS and called levels “telescopes”??? 2:12
👍
a mountain takes so many physical steps to climb its shouldn't be based on someones feelings that gravity cheats actual height. yes earths sea tides are a thing and a based starting point should be on land surface with 0' feet representing Near Sea Level
their cups level is half full 😅
The "physical steps" would be the way to measure a mountain's height. I would depend on the mountaineer's ability, training, the length of his/her legs, tiredness, that day's weather - and everything would change with every measurement taken by a different mountaineer. Not to speak about the shape of the mountain: the height *is not* the length of the trail to arrive at the summit, but the vertical height from a determined point down, up to the summit. If steps where the only way to measure mountains, lower mountains hard to climb would be ranked higher than high mountains easier to climb.
Gravity is not "a feeling," is a scientific fact that can be measured accurately. Google "Gravimetry."
And check at the David Butler's channel the playlist "How far away is it?"
That's a gross exaggeration of Earth's ellipsoid shape.
Yes, but a factual representation wouldn't have illustrated the point. At that size it would have just looked round.
@@M.Campbell Yeah but they need to make it clear that it's exaggerated and they didn't. There are a surprising number of people that really think the Earth is squashed like a football because of careless use of these representations.
So what…Colorado “mountains” are tiny anyways…14,000 feet from sea level yeah, but all these “mountains” start at such a high elevation…they’re more like hills that just happen to be 14,000 feet above sea level
Come & summit these small hills.
You don’t know what you’re talking about.
@@jray4131 I don’t know what I’m talking about? What I said isn’t opinion, it’s fact….
Most of Colorado mountains when measured from base to summit are about 5,000 ft average…
By the way, I live in Alaska….. with real mountains….
"Anyway," not "anyways." Hey go climb a few. Chances are you won't make it unless you have spent at least a week altitude acclimating. And maybe not even then.
@@frequentlycynical642 😂😂😂😂😂🤡🤡🤡🤡🤡🤡
Brother are you seriously gatekeeping mountains. Grow up friend
Please say "height" instead of "heighth"
Colorado was a great state until the California yuppies destroyed it!!
California was a great place until the Rust Belt refugees destroyed it.
@@DPT663 Those Rust Belt refugees picked the crops during the First Republican Great Depression, then manned the armament and vehicle factories during WWII. I moved to CA in 1981 and it still was an amazing place.
They shrank, they didn't shrunk. Please use a dictionary.
They shrink; they shrank; they have shrunk.
Present, past, past perfect.
No, no, no... This is government work. Therefore it is shrinked; they shrinked the mountians, the mountains shrinked, the mountains have shrinked, the mountians will shrinked, the mountains will have been shrinked by then.
@@Laudnumify
Your brain is government work, they live there rent free 24/7/365😂
@i-love-comountains3850 The government doesn't usually deal with mountians so this concept doesn't seem to make much sense. However, if you apply the concept of "shrinked" towards the national debt you'll see that it makes perfect sense. "The government has shrinked the national debt every year since Reagan was in office and the national debt will be shrinked every year from now on regarless of who gets elected".
@@i-love-comountains3850 I'm sure they would be surprised to learn they have no mortgage.
So, we've measured sea level and elevations for 250+ yrs but we need to put that aside and use "gravity" data. Regardless, the sea levels are not rising. My guess is the 2ft difference will be used to claim sea levels have risen 2ft and then tax you again.
What about all the islands that have disappeared to rising sea levels in the past 50 years? Psyop?
@@phaedrus000 No islands have disappeared because of rising ocean. There are many islands around the world that are only a few feet above sea level and they are still there....I've listened to this nonsense since the 1960's. The latest claim I've seen says ocean levels are up 8" in about 100 yrs. Nonsense.
@@TheHypnotstCollector Psyop, got it.
Sea levels aren't rising? Are you merely uninformed or an idiot? Sea levels are rising all over the world, and quickly. America's Gulf coast has been severely impacted in just a few decades.
How many ways can we spend taxpayers money!
If you can't understand the public utility of accurate survey data than we wasted far more taxpayer money on your schooling.
@@zacharywiedner327 Spot on!
If you can't understand how money is squandered on nonsense.......@@zacharywiedner327
Are people going to finally realize the surface of the earth is flat
All these scientists and none of them have the capacity to realize we are not on a ball
At what point are all these people going to start being honest and teaching the children the truth
If you can see 20 miles we are not on a ball people are very strange
If you can see 20 miles that means you are looking downhill. The only thing strange is how anyone at all can take flerf theory seriously when it's been so thoroughly debunked and all observable evidence is consistent with a spherical Earth.
Nice bait mate.
