The picture was about sailing the longest direct line.
It’s not the longest anyway, but that’s what it was about. Technically one could sail infinitely many times around Antarctica in a straight line.
around Antarctica in a straight line
No, that’s not Earth’s great circle, you’ll be turning slightly. It only seems straight on most map projections because they want latitudes to be horizontal.
It would, however, seem like a straight line to whoever was on the boat, because they’d be traveling due west the whole time, and the course corrections they’d have to make to keep going west would look the same as course corrections needed to account for wind, ocean currents, etc.
I know but you need to be the right amount of pedantic. Too little and any sufficiently large curve seems straight, too much and you point out that there is no straight line on the surface of a sphere.
Well, I stand corrected. I guess we’ll need to wait for the ice on the North pole to melt before we can make a more stupid voyage.
Because going in that route would make it touch land which in the twitter post it says straight line without touching land

India. You would have to set off somewhat perpendicular to the Indian coastline to be perfectly straight.
For some reason I don’t think this is true.
A straight line connecting two things does not necessarily have to connect to said things perpendicular to their border.
Not to mention, India’s coastline is very much not straight on a local scale. You’re bound to find a place where it turns perpendicular to the journey close to the theoretical starting point anyway.
Yeah but, I’m talking about this particular case, not making a mathematical rule. You have to move away from the coast, and then cannot turn, so you have to head towards Africa. You can’t set off toward Australia. Although I hadn’t considered that you can just move the starting point. So, there’s that.
Alaska, Canada, Russia, a few on the -stans.
This is the longest straight-line all-water route on earth.
I’ve always thought Australia was a trouble maker.
Every line is a straight line in one dimension
Today on the internet: Fun with spherical geometry.
THAT would be one god damn brutal sail. Both horns, Southern Atlantic crossing followed up by the Indian Ocean.
The range of foulies you would need to bring would be 3/4 of your pack. Foulies underwear and A sock (you’re going to lose one anyways)
I assume you mean “both capes.” While this line does come within a few thousand miles of the Horn of Africa, that’s not known as an especially hard sailing area but maybe for pirates.
Sailing this line in the other direction would be considerably harder.

Cmon man. Yes I’ve been a few places in sailboats. North sea in the winter for one. You clearly were trying to refer to Cape Horn and The Cape of Good Hope (or Cape Agulhas). Just take the L and don’t be a twat.
OMG I got a word wrong.
Ridiculous. This line is clearly gay.
This whole map is woke.
This is bi erasure.
Saying that it’s bi erasure is gay erasure.
We claimed it is erasure first, and now here’s our flag.
Hey, you even have the eraser right there is the middle! I suppose that makes it convenient?
Lmao at the admission that the entire identity of being bi is claiming erasure and playing victim.
I really do love convenience!
Never thought I’d get to use “bisectional” outside of JD Vance jokes
Not even 10 am and I’m being erased.
It’s bi sectional.
Line that is straight in two dimensions.

And like 5 million other movies
You youngsters with your Einstein Rosen-bridges! Always in too much of a hurry to take the scenic route!
A straight line may be the shortest distance between two points, but it is by no means the most interesting.

I honestly believe that sometimes, my genius, it generates gravity.

Hey that’s neat pulled it up in a 3d globe web app and its pretty close to straight
I dont know much about straight lines, but he sure does look happy.
This reminds me of some maps by Andy Woodruff.
They weren’t made to find long lines, and picking out a single line can be a tad difficult, but it’s very interesting nonetheless.
South America’s reach is incredible, compared to size that is
And it’s mystery is exceeded only by it’s power.
Well there’s the one guy in Northern India who gets a peek at South America from between Madagascar and the African continent.
There is also just the one straight path from the US east coast (Florida) to Asia.
Globists will argue that on a globe this is a straight line. Seen these arguments before, don’t work on me
Nice. Be proud.
Dunno what of, but be proud anyway!
Thanks! I’m very proud of seeing the truth. Watch this short video and you will being to understand. But watch it to the end, it’s short enough
Don’t know about other clients, but vger shows a thumbnail of the video
Better?
The ending really brings the whole video together. Thanks for sharing!
You know, I’d never actually thought of it that way. Very informative video for it’s short length. Thank you for sharing.
I’ve seen that video a hundred times and it never fails to disappoint
You’ve made a believer of me.
One of the most compelling arguments I’ve heard. I must say I was a skeptic before but this really opened my eyes

Your dad and I think you should start looking for a job.
I can’t legally work in my country I’m not old enough
But still, don’t you hunger for the mines?
Toiling in the meme mines.
Edit: I have just finished reading The Neverending Story and this reminds me of the last part where Bastian works in the picture mines until he finds the right picture.
Fuck it

There was a conversation I read a while ago that showed how a sailboat could travel a straight line over water from Halifax, Nova Scotia in Canada, travel southeast and end up on the west coast of British Columbia.
Basically sailing from the east coast of Canada to the west coast of Canada in a straight line.
The line was published by David Cooke in this YouTube video. It lies on a plane but is not quite a great circle (in practice, you’d be turning slightly) and good luck sailing over the Antarctic ice shelfs this decade.
Space-time itself is curved, therefore there is no such thing as a straight line.
Please correct my layman understanding if I’m wring here. But isn’t everything traveling in a straight line until an external force is applied. For example the earth orbiting the sun is traveling in a straight line in a curved apacetime. Also if you jump, the moment you leave the ground until you touch it again coming back down you were traveling in a straight line.
In my understanding, since gravity is acting on us, an external force is applied when we jump. That’s why a jump is a parabola. “Gravity’s Rainbow”
What they are getting at is that gravity is not a force so much as your mass trying to travel in a straight line through curved spacetime. The weight you feel is because the surface of the earth is in your way.
Get into low earth orbit and that straight path has you going in apparent circles around the planet. You are very much within the earth’s gravity but you don’t feel “weight” because the surface of the earth is no longer blocking your path. You still have mass and inertia and all that, of course.
Yes, that’s exactly what I meant :D
I dunno lol
Also if you jump, the moment you leave the ground until you touch it again coming back down you were traveling in a straight line.
relative to the body of earth, including its rotation it would be an arc path, and including it’s tilt it would be 3d, if we also include the travel around the sun in orbit, that elongates it around the orbit, so uh.
Space-time itself is curved, therefore everything is moving in a straight line, it only appears to be curved to the outside observer
Not true, as when space bends, it bends the rulers and compasses too. We experience no spatial distortion.
A person traveling near the speed of light doesn’t feel like time is slower for them (but it is and we can measure it)
The principle is equivalent.
That said, it’s not a straight line in any topology standard I am aware of.
Sure you could CREATE a topology framework where this would be considered a straight line, but there is no real world model that could come even close without so much mass being concentrated in static relative areas, and EVEN THEN it would only be straight for a predetermined instant before the mass deforming spacetime began interacting with each other.
That’s the problem with spacetime deformations, almost no layman takes into account the ridiculous amounts of static mass to make those strange topologies.
We have geodesics for that.
If anyone wants to grasp the basics: here is some fun reading (leading on to some beautiful math). Changing the idea of parallelity leads to hyperbolic geometry and other fun stuff. :)
Low IQ: it’s not a straight line
Medium IQ: it’s a geodesic on a sphere, so it is a straight line
High IQ: it’s not a straight line
He’s right, you know.
About the line?
About everything, damn it!
It’s a straight line through non-euclidean space
unfortunately in reality it is a curved line on a sphere
In actual reality there would be wind and water currents diverting any ship sailing that route from the depicted “line” anyway so the whole argument is pointless
The only straight line paths in the universe are followed by electrostatically uncharged non-accelerating objects in free fall in a vacuum. Or massless particles.
What if we assume the ship is actually a spherical cow
Whole Universe eh? That exists and is bounded on a curved space time.
I’m just joking, but you can really take this to the extreme lol
Spacetime is curved. Inertial paths through spacetime are straight.
Euclidean space is not the only space where straight lines are possible.
Nuh uh. My fifth grade math teacher told me that if I drew a line with an arrow on graph paper and no other line intersected it, that it would continue on into infinity!
