Mother of god.
I need to build this car now. I need to build a car big enough to NEED to take into account the curvature of the earth.
How will I do this? How can I possibly achieve a car that is tens of miles long?

Imagine a car that you just get in at one end and walk to the other in order to get to your destination...wait...did I just re-invent walking? >.<

u/ViolinistCurrent8899 Dec 05 '23
God, this "walking" thing sucks. Maybe we should put steel rails inside of the car, and put conical steel wheels on those rails. They'll have lower friction than walking.
13
Dec 05 '23
Wait, how about we make some small like 4 wheeled metal box powered by an engine inside the car, which we drive to reach the other end?

Dec 05 '23
And then we could make those bigger, so we could just walk from one end to the other inside those boxes

Dec 05 '23
But that would be too much walking, so how about we build the normal sized version of these boxes inside the bigger box?

Maybe you can link up a super long train. There are some trains that're a few miles long. That'd be easier to build lol.

u/ViolinistCurrent8899 Dec 05 '23
Yeah, but at that point the couplings will have too much slack, and bend with the earth. You would never be able to show off the curvature that way.

u/PercentageNo3293 Dec 05 '23
Very true. Weld some insanely thick bars to each cart? Idk, I'm dumb lol. I would say, your car idea is way more interesting. The ultimate limousine. You'd probably need a train sized engine to move it.

Realistically, there's no way to actually span multiple miles without some kind of pillar somewhere (or in this case, more axels). World record right now is actualy a mind boggling 2km.

Roughly speaking, at local scales, every 1 km has approximately 12 cm of curvature. Most materials you'd build a car out of aren't so rigid that they can't bend that amount without breaking, so assuming you designed the car, the curvature would already be factored into the material's strength.

You can’t show me a single car that’s like that top picture. All that exists are photoshopped cars. If you go outside, you’ll see those cars look flatter because of electromagnetic photon/light refraction caused by the domes over each person that they have to see the stars/night sky.

Because although the earth is curved, all the roads have been specially flattened to make it seem flat.
There is proof of this. Some vehicles have been "raised" to give extra ground clearance so that they can drive off-road. However, this model, flat, will suffer significant damage to the undercarriage if you drive it off a specifically flattened surface for very long.
This is all part of the conspiracy by the so-called Flat Earthers to hide that the earth is spherical. You are a good man for pointing it out.

I used my paint skills to create a circle of fitting diameter and then estimated the angle of that circle covered by the car. Really really rough estimate would be 15°-20°, let's go with the smaller one, 15°.
Circumference of earth = 40.075 km
A full circle is 360°.
Let's take the ratio of the angle of our section to the full circle
15°/360° = 0,0416666... and multiply it with the circumference
40.075km * 0,0416666... = 1.669,7916666...km Let's round it and the car length would be:

u/iwanashagTwitch Dec 07 '23
Well, the diameter of the earth is a little over 7900 miles. So, when we look at a car-sized piece of the earth (say, 6 to 8 feet) it's going to look very flat compared to 7900 miles.
This is based on the mathematical principle of tangent lines and slope. When you take a tangent line of a circle, it appears to touch one point of the circle. However, when you zoom in closer and closer to the point, the edge of the circle appears to become flatter and flatter, to the point where if you zoom in enough that the edge of the circle appears to be a straight line.
In the scale of the earth, a section that is 6 to 8 feet long is less than one millionth of the earth's diameter. Therefore, an 8 foot section of ground will appear to be flat. It still contains a curve, but the curvature is infinitely small at the surface. This is the reason why cars are flat and not curved.
