And as far as the ship video is concerned, how large a wake do you propose a cruise ship would make?

It will only make a wake to the rear of the ship, with a bow wave spreading out from the sides, always behind the bow.

So, in the video above, where one ship goes away, the other approaches the camera, the second one will have no wake between it and the camera or observer.

Let's do the long hotel corridor, then;

The corridor is 12 ft high from floor to ceiling. You, the observer, are 6ft 4ins tall, so your eyes are at exactly 6 feet above the floor, and 6 ft below the ceiling.

Let's ignore what's happening in the far distance for the moment. Yes, the ceiling, floor and walls APPEAR to converge to a point, but we all know the corridor does not get narrower or shallower.

Do you agree that the floor is, at all points, below your eye level? Eye level is parallel to the floor, at 6 ft above it, so you must be looking downward when you look at the floor, right?

Do you agree that if you look at a point on the floor some 20 ft away, your line of sight to that point, from 6 ft above the floor, passes through a level of 5 ft, 4, 3, 2, 1, 6 inches, down to zero?

It's a straight line of sight, isn't it? No refraction, fog, or other atmospherics to distort it? It doesn't curve upward, then back down to reach the floor. You're looking straight at the floor. Right?
