I might not feel the ship move but if I look at my surroundings, I can SEE it move. In a car, I feel myself moving.

Lol?
It depends how high you throw the ball.
If I throw it 3 feet in the air it will come right back down in my hand.
If I throw in 30 miles in the air, it's not going to land in my hand.

You need to get a physics book and look at the optics that are at play here. In order to see the curvature of the Earth you have to be about 35,000 up MSL and a wide filed of vision
| You should be able to detect it from an aeroplane at a cruising height of around 10,600 metres (35,000 feet), but you need a fairly wide field of view (ie 60 degrees) and a virtually cloud-free horizon. The reality is that clouds, hills and mountains mean we rarely get to see the kind of perfectly flat horizon where the curve would be most obvious. However, you can detect the curve of the Earth from ground level at the coast with a pair of binoculars – just look for distant ships on the horizon and you’ll see that their hulls start to disappear before their masts and other superstructure. Ancient Greek scientists, who spotted this without any optical aids, used this to conclude that the Earth was round. |
If the Earth is a flat plate, why do you come back down when you jump up in the air? DO you have a name for this magical process?
If you cannot see land you cannot tell the ship is moving.
You feel the car move because of imperfections in the road.
And the only way that could happen is if the Earth is spinning. If the Earth is not spinning, it would come right back down to your hand.
According to heliocentrism, the earth rotates west to east at approx. 1,000 mph at the equator.
Yet, if I fly in a plane east to west, or west to east, the moving earth has no effect.
Singapore Airlines has a flight from Singapore to The Maldives. Both these cities are very close to the equator.
The flight from The Maldives to Singapore is said to take 4 hrs 45 min. The flight from Singapore to Maldives is said to take 4 hrs 30 minutes. The difference is because of wind.
If I am traveling from The Maldives to Singapore (West to East) with the alleged rotation of the earth traveling 1,000 mph, and the plane is traveling 500 mph, then the plane is only traveling half the speed of earth, it means I never would get there.
Going east to west, it should only take an hour because the earth would be rotating under the plane in my favor.
How can both flights take the same time, if the earth is moving 1,000 mph from west to east?
It would have the same effect if space was revolving around earth.
If space was revolving around the Earth, what causes the ball to move?
For your consideration:
During the flight, you need to get up to use the restroom. There's one 10 rows in front of you, and another 10 rows behind you. Does it take longer to walk to the one that's moving away from you at 600 mph than the one that's moving towards you at 600 mph? No, because you're moving at 600 mph right along with it -- in the ground-based frame of reference. In the frame of reference of the airplane, everything is stationary. Similarly, the airplane is already moving along with the surface of the Earth before it takes off. The rotation of the Earth has no direct significant effect on flight times in either direction. That's to a first order approximation. As others have already said, since the Earth's surface is (very nearly) spherical and is rotating rather than moving linearly, Coriolis effects can be significant. But prevailing winds (which themselves are caused by Coriolis and other effects) are more significant that any direct Coriolis effect on the airplane. |

Because the speed of the plane (and wind) is described as relative to the ground not the centre of the earth. The planes speed is limited by the speed and direction of air it flies in (which is about the same as the earth's rotation below it, with differences called wind)

And bang goes that theory. This was from the recent parachute jump from the edge of space. The picture shoes the curvature of the Earth but there is no distortion of the man nor the capsule.Spoiler

1. Is that the Red Bull thing? Filmed with a Go Pro. It has a fish eye lense. Watch the video and you ll see the horizon go convex, to concave, to straight, and back. Is the horizon wavy and constantly moving? Because that's what the video shows.
2. You CANNOT see the curve in the ocean. The ships just get further away and appears to be disappearing. I hate this arguement t that things get smaller when they move farther away so it's curved. No. Things look small and eventually invisible from a great distance.
3. Things fall back to earth because of density. No magic forcefield. Just denser things fall.
Look closely at the picture as it is a single frame. If you wish to discuss camer optics then please at least Google the topic before beginning.
You can from an air liner if you have about a 60° field of vision.
Why do dense things fall back down? What is going on that causes denser objects to fall?

1. You cannot see the curve from an airliner. Any independent observation or film always shows a flat horizon at eye level. There are go pro lense correctors that will fix the distortions.
2. Their density is what causes them to fall. Their density is, itself, responsible for making denser objects fall. Why does there need to be a magic force to suck it back to the earth?
The same reason a Foucault Pendulum would do what it does in a geocentric earth.
That's not a very good analogy considering my feet are touching the plane, and I'm in a pressurized cabin.
How about at the airport, you, me, and another guy gets on one of those movable walkways.
You stand still, I walk east (the direction the people mover is going), and the other guy walks west. All three of us are moving in the direction the walkway is moving, but we gain separation from each other and from you.
And, it would take me much less time to move east 100 feet, then you and the other guy.
you will need a much more precise definition than " eye level" for thus statement to make any sense.
Why? Density is a definition that is unit mass per unit volume. That us all. If you have two balls, steel and rubber, does one fall faster than the other? Let's say you have two humans with the same density, one is 6' tall and the other is 4' tall, do they weigh the same? Why or why not?

1. Eye level is straight ahead.
2. Exactly, they both fall at the same speed. They both are more dense than the atmosphere so they fall back down. At the same speed. It's the density itself. I've heard other theories where "gravity" exists but is dictated by temperature. I'm not sold on that, but it makes more sense than Newton's Star Wars force.
It is a far more accurate analogy than yours. Here's why, your analogy ignores the air.
As the Earth rotates the air above the Earth rotates with it. Wind currents are present but even that are rotating with the Earth. As the plane flyspeck against the rotation it is flying into the column of air. From a reference plane that is not Earth, you would see the plane moving in one direction and the destination rotating towards it. When the plane is flying with rotation you would see it moving much faster towards a destination that is moving away from it. If your reference plane is on Earth, you would not see this effect as the plane is only moving relative to the Earth. From a reference plane on the moon, then you have the Earth movie go and the plane moving and you can clearly see the effect on the planes velocity.
