Are railroad track completely parallel - if so why do they meet at the horizon every time?

By what black magic does this occur?

Gravity cant bend steel rails.


They don't really meet at the horizon. The distance between them eventually gets to an angular size that's too small for an average human eye to resolve. But this all depends on the eye and the distance to the horizon and the distance between the railroad tracks. It also has nothing to do with the horizon itself. Any two parallel lines will appear to converge the further away they get, regardless of direction. If you were to lift a railroad track vertically, so it points to the sky, you'd see the exact same effect. This is clearly apparent with tall buildings, crepuscular rays, and any flying object like an airplane.

No black magic, just very very simple geometry. This is the kind of thing you'd probably study in grade 7, give or take a year. Most high school students wouldn't have any trouble explaining the effect and actually calculating the angles and distances.

LOL.

Okay.

So what if I say that ChivasRegal is the one who does not understand perspective & convergence?

Looks like we are now at an impasse, with both using the same argument to disprove the other's claims.

In your solid scientific methodology, how do we now proceed to decide who is actually right?


didn't answer my question, dodge more

cool, you have an IQ below 60, thanks for proving it.


That's for everyone posting Santa emoji's and proving Santa is a conspiracy kids are tricked into by every parent
