An experiment to disprove FET

I have an experiment for all you FErs that proves that earth is spherical. If you were to watch the a sail boat as it is leaving port, the ship would slowly go farther and farther out to sea, becoming less visible. But if you were to watch very carefully the last visible part of the ship , that can be see will be it's highest point (the sail) on the horizon, while the rest of the ship will not be visible. This is because as the ship moves father away from you it is essentially moving "down" relative to your point of view, and the lower portions of your ship are too "low" to be perceived, while the higher portion still remains visible. If the earth were flat, all portions of the boat would dissapear equally until the boat was too distant to be perceived.

LOL you're new here.

Tom Bishop: It's F-ing WAVES, Dumbsh*ts!
OK, Tom.  Just calm down.
Tom Bishop: WAVES!

I was not aware of this property of F--ing waves Enlighten me.

Ok.  Tom Bishops seems to think that there is a vanishing point on the horizon just below the waves.  He says that when the ship get far enough, puny little waves are going to obscure the ship.  We've had arguments on this: Wave Crests and Sunsets
Obviously, no wave will obscure a ship and make it appear to sink.  But Tom Bishop uses flawed reasoning.

Another theory is atmospheric distortion.  To put it in a famous Tom Bishop statement: AIR IS BLUE.

Yeaaaah...

Tom's theory is that the waves in between the boat and the observer will make the boat appear to disappear from the bottem up, as the farther away it gets, the more likely a wave that can block the view of the bottem will occur. The flaw with this is that no wave is going to block a ship tens of feet tall.

I have one for Tom to disprove that he won't be able to, but it's late, and I don't have the energy or the brain power to post it in a way that others will understand. It involves two seperate viewpoints and the blockage of the ship.

Tom doesn't have any theories. He has a random text generator. We have covered this children. 

Example:

Tom, what about the horizon?

Tom:

There's a voice that keeps on calling me. Down the road, that's where I'll always be. Every stop I make, I make a new friend. Can't stay for long, just turn around and I'm gone again. Maybe tomorrow, I'll want to settle down, Until tomorrow, I'll just keep moving on.

Top Cat! The most effectual Top Cat! Who's intellectual close friends get to call him T.C., providing it's with dignity. Top Cat! The indisputable leader of the gang. He's the boss, he's a pip, he's the championship. He's the most tip top, Top Cat.

80 days around the world, we'll find a pot of gold just sitting where the rainbow's ending. Time - we'll fight against the time, and we'll fly on the white wings of the wind. 80 days around the world, no we won't say a word before the ship is really back. Round, round, all around the world. Round, all around the world. Round, all around the world. Round, all around the world.

Wow. You came up with the most overused example ever. And you didn't even read the faq to do so. You should really get an award. That example is everywhere.

Actually, everywhere that it is, it has been disproved. So he was well withing his rights to post it here. It is also not in the FAQ.

I disagree.

On which part?

I agree.

I think my theory was better, with the ship-eating whales

Waves oscillate. If a wave appears to block the sail at one moment it should not do so the next. If Tom is right you would see a ship... No ship... A ship... No ship...

Is this what is observed?

Didn't think so.

This is explained by the acceleration of earth.

Earth accelerates up through the lower light path, obscuring the lower part of the ship, then more and more as the ship gets further to sea.

Like, Wow.

Which bit of the FAQ do I have to read before that makes sense?

Which part is confusing (I had a typo I fixed).

In what manner does Earth "accelerate through the light path"?

The earth accelerates upwards.
The light travels at a constant velocity.

This means the longer the light travels parallel to the earths surface, the closer the earth will come to it, until, eventually, it blocks the light. This phenomena starts with the light closest to the earths surface, or the light that reflected off the lowest parts of the hull.

The further the ship is from the observer, the more of the ship, starting from the bottom and working up, will disappear from view.

Nope. Do the math. The acceleration isn't enough to make even an inch of difference. The RE Primer contains a worked example.

I have done the math. The math in your primer is incorrect and, considering the source, expectedly false.

That would produce a linear horizon drop-off (x amount of vertical change in y distance) , not one consistent with a curve, ie, it would be easy to test. See if a ship of height 2x disappeared over the horizon at twice the distance of a ship of height 1x.

Oh do enlighten us by posting your math here. Oh, and let us know about the error you've discovered in the RE Primer so we can correct it.

That is correct. Observations show a linear visual regression of ships.

How tall are these ships? I'm guessing they'd have to be enormous before the effect became distinguishable from a linear one.

Option 1

That would produce a linear horizon drop-off ... it would be easy to test. See if a ship of height 2x disappeared over the horizon at twice the distance of a ship of height 1x.

Option 2

Pick your argument, that I might reject it.

Actually I was talking bollocks. The drop-off would follow a parabolic function, you already said a linear trajectory was observed - which would neither fit an accelerating FE, nor a spherical Earth paradigm.

Either you lose, or you admit to making it up as you go along.

I like that response....(Working on Math)

Ummm is the math even relevant because if the light from the boat is bending while the universe is acclerating, then wouldn't the light from the waves/water around it also bend to an equal degree? So the boat wouldn't appear to be anymore underwater?  Could be wrong just throwin some idea out there.

I don't think he means it's bending the light. He means that as the light travels across the Earth the Earth moves upwards and cuts off the light.

Thinking about it more: If the Earth was accelerating upwards, then the horizon would be shrinking all the time. The suggestion only works if the Earth is moving upwards at a constant velocity.

Take a ship 10m tall and assume a 'horizon' 30km away. This means, according to an accelerating earth model, that in the time light travels 30,000m horizontally the Earth has moved 10m vertically; ie in about 1/10,000th of a second. Meaning that the vertical velocity of the Earth at this point in time is about 100,000m/s.

After a day accelerating at 1g (call it 10m/s/s) the Earth will now be moving at approximately 100,000+(10x3,600x24)=964,000m/s. The horizon distance of the same ship will now be, well about a tenth as far away, obviously.

I think that kills that
