Dude that’s awesome. How did you make these images??
I didn’t, it’s from a spiegel.de article
That’s not a straight line, although it is possible to follow without changing direction😊
I KNOW IT’S BASICALLY A CIRCLE IN 3D SPACE. There is an exact amount of pedantry at play here, and you’re going over.
Would you say that they… crossed the line?!?! 😏😏😏
In our space time frame of reference, we never change direction, we travel in a straight line. It’s a straight line.
And when Im walking, in my frame of refrence, the houses on the side of the road move behind me.
But following the surface of a sphere causes you to constantly change direction
Correct! Technically :P
Would straight plane be as understandable?
Ridiculous. This line is clearly gay.
It’s bi sectional.
This is bi erasure.
Not even 10 am and I’m being erased.
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?
I really do love convenience!
Lmao at the admission that the entire identity of being bi is claiming erasure and playing victim.
Never thought I’d get to use “bisectional” outside of JD Vance jokes
This whole map is woke.
I dont know much about straight lines, but he sure does look happy.
Why’d they go that way? They could have gone the other way and the line would have still been technically straight, but the route looks like it would have been shorter.
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.
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.
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.
Because going in that route would make it touch land which in the twitter post it says straight line without touching land
What land would it touch?
Alaska, Canada, Russia, a few on the -stans.
This is the longest straight-line all-water route on earth.
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.
I’ve always thought Australia was a trouble maker.
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
The ending really brings the whole video together. Thanks for sharing!
I’ve seen that video a hundred times and it never fails to disappoint
One of the most compelling arguments I’ve heard. I must say I was a skeptic before but this really opened my eyes
Got error: “Sign in to confirm that you’re not a bot”
Hmm, really makes you think…
Don’t know about other clients, but vger shows a thumbnail of the video
You know, I’d never actually thought of it that way. Very informative video for it’s short length. Thank you for sharing.
You’ve made a believer of me.
*folds world map in half
*sticks pencil throughReminds me of the movie Event Horizon.
I honestly believe that sometimes, my genius, it generates gravity.
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.
-The Third Doctor, Doctor Who
HYPERSPACE
Space-time itself is curved, therefore there is no such thing as a straight line.
Space-time itself is curved, therefore everything is moving in a straight line, it only appears to be curved to the outside observer
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. :)
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.
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.
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.
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!
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.
What if we assume the ship is actually a spherical cow
I feel like this is related to the can’t measure the coast’ thing.
Like if you zoom in enough you are always traveling in a straight line.
I don’t know… straight, I would assume, means that I could walk or drive a vehicle and not turn at all, ignoring any external influences like waves and currents in this case.
But your vehicle would itself “curve” “downwards” due to gravity, surely a straight line means that you can point a laser, or a hypothetical 0 mass particle beam, uninterrupted from your starting point to your destination.
in ur every day life if u travel in a car without changing direction would u say that u went in a straight line or in an arc. Clearly u are just trying to be a pedantic cunt for no reason.
Depends on your frame of reference. When traversing the surface of a globe, your described concept of a straight line isn’t intuitive.

You just discovered the field of calculus! If you look closely enough at any smooth function it looks locally linear, and the slope of that linear function is it’s derivative
Not quite what’s happening here, here the problem is if you consider geodesics on a sphere to be straight. In special geometry they are, for all intents and purposes, but in higher euclidian geometry they form large circles
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
Eats the mines
TIL that “straight” can mean “curved”, apparently 🤷
To clarify, as youve not understood the joke, nor read the comments. As far as I understand it, were you to start sailing at the first point, you never have to turn to arrive at the second. That’s why it’s “straight”. On the 2d plane you are completely correct however.
For proper and better informed explanations read the other comments :D
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.
Well there’s the one guy in Northern India who gets a peek at South America from between Madagascar and the African continent.
South America’s reach is incredible, compared to size that is
And it’s mystery is exceeded only by it’s power.
Every line is a straight line in one dimension
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.
Today on the internet: Fun with spherical geometry.
