There is a road in Scotland where bicyclists have to pedal hard to ride downhill... but then coast uphill. Why? | For more World's Strangest, visit www.sciencechannel.com/tv-show... Subscribe to Science Channel! | ru-vid.com_c...
a1z4 The amount of accidents that occur on this road is crazy because of idiots (including locals unfortunately) stopping to try this. Cars coming around the corner at the top have no way of seeing stationary vehicles and either plough right into them or swerve to avoid them... Sometimes people get lucky.
Surly you have tried it once before right ? anyway since you know the road and the fact you can find someone in the middle of the street you would be cautious while driving on that particular spot, my point is to leave people alone and who ever want to see it is not your business and just be kind to others and be happy that you are healthy and living .
@@d12parson he probably did figure it out but they just edited a cut out of him saying "Absolutely not" with no context whatsoever. It sounded like him saying "absolutely not" was within a full sentence and that sentence could have been anything or them asking him any question. Don't let manipulative editing/scripting fool you. Any decent surveyor would/should know what's going on.
@@lioncross1849 Not the editor, the producers. They wanted to prolong the mystery to get another "expert" on board to further dumb it down for the viewers.
Vwolf: The landscape is opposite hence the road goes up while the land goes down and vice versa. You could create this in your yard with sand or earth or...and charge people money giving this illusion.
+Pyaar Suravira A level wouldn't tell you anything other than which way is up relative to the direction of the gravitational forces affecting it. It would be mostly worthless when trying to determine if you are experiencing an optical illusion or a legitimate gravitational anomaly. If non-magnetic things are rolling "uphill", a level is *_always_* going to tell you that direction is "downhill", regardless of the actual altitudes of the "top" and "bottom". The only time a level would be useful is if you could find a spot where it suddenly begins reading differently than previous measurements would suggest it should. For example: If while at the top of the hill, the level reacts as you would expect, but as you travel towards the bottom, it begins to reverse which way is "up", then you've just found yourself a genuine anomaly. If, on the other hand, measurements consistently show the same direction as "up" for the entire length of road, you've just wasted a bunch of time and have gotten practically no useful information. Determining the altitude of the "top" and "bottom" of the hill is the only surefire way to determine whether it's an optical illusion or a gravitational anomaly.
+Wells actually, a level would tell you which way is up and which way is down. A level with a small air bubble works using gravity. Supposedly the cars are being pulled "up" br gravity (doesnt really matter whats pulling the cars up). So a simple level will tell you which way up actually is, and you'll be able to see that "up" is actually down. Problem solved!
Shehan Conrad The fact that the air bubble works using gravity is the precise reason it's useless in this particular situation. It is incapable of telling the difference between an optical illusion such as the one in this video and a genuine gravitational anomaly, should such a thing exist on Earth. If the "top" of the hill really were at a higher altitude than the "bottom", and objects are rolling uphill, the level is going to tell you that the top is the bottom. Without knowing the altitudes of the two points, you have no way of knowing whether the level is reporting "up" relative to the center of the Earth, or some other gravitational force. Remember: "Up" is simply the opposite direction of the sum of the gravitational force vectors acting on an object.
the psychologist was totally unnecessary lol. if the surveying results show the real elevations, then the so called 'illusion' can be solved by the engineers themselves.
MarcLloydz Obviously the car would still roll downhill but the point of the video was to explain why downhill looked like uphill and I am sure you couldn’t explain that.
The "five senses" that grade school teaches us is woefully innacurate. We have more senses than that, one being our sense of balance with the main sensing organ being the vestibular system of the inner ear.
I drove this hill 40 years ago, and was convinced that gravity was reversed, until I stopped the car and took a pee at the side of the road, water always runs downhill.
ACTUALLY,its proven by mark shucbin a forensic motion picture analyst.he says that essentially creating a fake landing on the moon would be IMPOSIBLE!! In the 60s
To be fair the more jarring part of that sentence was the "we don't listen to our other senses". Our vision and brains actually do a lot of things to fill in a puzzle, so its not always accurate. However I don't get how other senses would help here. Taste the dirt? Feel the road? Hear the wind hitting the pavement at an angle?
+Alex Parr You just have to be really quiet so you can hear the hill tell you which way is up. But don't be too quiet, because then you might hear it telling you to swerve into the bicyclists.
I don't know, maybe you can't tell if you're upside down or not. We humans got some form of Accelerometer to sense forces and acceleration. Stand in a steep hill see your body's angle relative to the ground. If you argue that under water people can lose their way (as in which way is up or down), sure they do because underwater you get boyency force from the water that opposes gravity so you get less sense of gravity direction. In an airplane, without looking outside i know when the airplane tilts clockwise or counter clockwise. That's totally normal.
I remember an old student teacher I had back in grade school that told the class about her trip to Scotland and how they stopped their car on an uphill road and it moved forward on its own. I had no idea wtf she was talking about, NOW I know what she was talking about almost 20 years later. This is so cool!
The psychologist has it figured out. How cool. The same landscape phenomenon occurs here in Gold Hill, Oregon on Sardine Creek road. They have a mystery house set up here and they demonstrate water flowing uphill. Much like some of the rooms at the Winchester Mystery House in San Francisco there are rooms that will make taller people look shorter than others.
There’s also a road like this in Barbados! I went on vacation there and we took an Uber and he showed us a road he backed up and put the car in neutral and it pulled the car upwards! It was a sick experience!
I cant believe a video this long is required to explain why it looks like things are rolling uphill... is it not obvious? Did people truly believe that gravity was wrong on that particular road?
LAMOOOW maybe the way it was before made less sense before... we don’t know. It could’ve had a punctuation mark in the wrong place that confuses the reader. At least they had the “Ego” to care about what their comment appears to look like. ...Or they had a spelling mistake. We don’t know.
I remember a television programme years ago about a road in Scotland (probably the same one), that did this and I always wanted to see for myself. The fascination is not that gravity has been defied, it's the shape of the whole landscape that creates a false illusion. I still haven't seen it, but I fear that with all the head scratchers crawling in neutral along there, the Scottish highways authority will be placing armco barriers with built in bubble levels, very carefully set out with lasers beamed off satellites to avoid any confusion; and the illusion will be lost
It is most likely a similar optical illusion. NASA and DLR launched a joint mission known as GRACE which mapped the earth's entire gravitational field with astonishing accuracy. I highly recommend reading the Wikipedia page on the mission, it is quite fascinating how they pulled this off. Anyway, it was found that the min/max magnitude of earth's gravity anywhere on its surface is 9.7639m/s^2 and 9.8337m/s^2, which you likely would not even notice. As for it's direction, this can of course also fluctuate ever so slightly depending on location, but only if you had very very precisely calibrated equipment. As far as human senses are concerned gravity is effectively a constant magnitude and points directly towards the core, regardless of where you are on the planet. Hope I could provide some interesting information.
In certain situations it's hard to tell if you're going up or down hill. When in doubt get out and have a pee and see which way it flows. (= It's not that complicated!
We have one of these roads near to where I live in south Ireland. Little stream beside looks like it runs uphill and cars go “uphill” too. Always fun with friends to freak them out 😉
There is a similar place at Jenkinstown on the Cooley peninsula north of Dundalk in Ireland. It is known as Gravity Hill or Magic Hill. It is eerie to stop a car at the bottom of the hill and then see it roll uphill. I have long maintained that it is an optical illusion and, in fact, the car is actually rolling downhill. Thank you for confiming this. I now have a reference to show people in future.
There is a similar "slope" just east of Rome, in Italy. It is a very steep climb, which then levels out to almost horizontal and then climbs very steeply again. To the human eyem, it looks like one is going "up, then down, then up again", but if you measure the gradient, it is "hard slope, gentle slope, hard slope". It is really just an optical illusion, albeit on a very large scale. Very amusing to the turist ;)
1:33 "This looks like the top of the hill ,right? - No? - And this looks like the bottom of the hill, right? - Absolutely nope, no, you drunk? - WRONG. - Told you so..."
Thank you. I bicycle on a trail where a quarter mile segment of that trail seems to have the same effect as this road. I always thought it might be a wind current, but then even on a calm day I'm peddling "downhill." Case solved.
The whole presentation was dubious, and rather than the landscape playing tricks it appears that the presenters are playing tricks, first they get a load of complicated technology, then they get a orwellian to talk about "conspiracy theories" (God musta conspired with Himself when he made the dude and set the law of gravity), then they get a psychologist - All they had to do was get a water level commony found at a local builder's merchant or 99p shop and put it on the road. or if unconvinced and needing a bit more drama, one vertical stick and a protracter to measure the angle (-90* / +90*) ?or even more dramatic - two upright sticks of the same size and a long horizontal stick with a water level between the two, and see which stick is higher than the horizontal stick and use a bit of pythagoras theorem to clarify the angle.people were just left feeling inadequate and wondering at the complicated nature of the tests and hypothesis and some were even left to speculate since the displayed "horizon" wasn't level
I was in a minibus that stopped on that road when I was about 12, the driver was telling us all about this magical phenomenon. I looked around the place and concluded, optical illusion, drive on.. Next they’ll be telling us the earth is flat.
