Explain bendy water, you tell me how remains on a spinning ball, you explain to me why if you jump feet first at the top of your ball you don't come feet first, you explain to me crepuscular rays if the sun is 93000000 miles away. You explain to me how visable landmarks don't disappear behind the curvature when the calculus of 8 inches per mile squared is applied.

Please explain to me why there is a world wide conspiracy, involving every government, scientist and place of learning, to deceive us into thinking the world is a ball?
I really struggle to understand how someone who thinks your way gets on with their daily lives.
You believe every authority in the world has some sinister plan to make you think the world is round, yet you get up and go to the shops or work and live life as a normal person (I’m presuming).
I just don’t understand it at all.
You don't have to worry about me pal, I am a normal person that gets by just fine Why all the assumptions , it's simply I don't believe the earth is a spinning ball you might but I don't You believe everything that your government tells you, weapons of mass destruction, Hillsborough, and so on just a thought.

Gravity pulls it down towards the earth. That effect will always pull the water down. That’s why when you put water on a football it falls off towards the centre of Earth, the mass of earth being greater than that of the football.
Can you ask that one again in English? I have no idea what you’re trying to say.
Despite seeming to converge at a point, the rays are in fact near-parallel shafts of sunlight. Their apparent convergence is a perspective effect, similar, for example, to the way that parallel railway lines seem to converge at a point in the distance. The sun rays do converge to the sun, but the sun is much further away than the rays might make it look like.
Met Office in on it as well:

One typically sees further along the Earth's curved surface than a simple geometric calculation allows for because of refraction error. If the ground, or water, surface is colder than the air above it, a cold, dense layer of air forms close to the surface, causing light to be refracted downward as it travels, and therefore, to some extent, to go around the curvature of the Earth. The reverse happens if the ground is hotter than the air above it, as often happens in deserts, producing mirages. As an approximate compensation for refraction, surveyors measuring distances longer than 100 meters subtract 14% from the calculated curvature error and ensure lines of sight are at least 1.5 meters from the ground, to reduce random errors created by refraction.
However, ignoring the effect of atmospheric refraction, distance to the horizon from an observer close to the Earth's surface is about:
where d is in kilometres and h is height above ground level in metres. The constant 3.57 has units of km/m½.
Examples:
- For an observer standing on the ground with h = 1.70 metres (5 ft 7 in), the horizon is at a distance of 4.7 kilometres (2.9 mi).
- For an observer standing on the ground with h = 2 metres (6 ft 7 in), the horizon is at a distance of 5 kilometres (3.1 mi).
- For an observer standing on a hill or tower of 100 metres (330 ft) in height, the horizon is at a distance of 36 kilometres (22 mi).
- For an observer standing at the top of the Burj Khalefa (828 metres (2,717 ft) in height), the horizon is at a distance of 103 kilometres (64 mi).
- For an observer atop Mount Everest (8,848 metres (29,029 ft) in altitude), the horizon is at a distance of 336 kilometres (209 mi).
Now seeing as I’ve answered that, do me the favour of answering mine. Please note I’m using a phone in answering over in the Middle East using satellites to bounce the signals back to you. Something that wouldn’t be possible we’re the earth not a sphere as the satellites would not be able to remain in geostationary orbit. I’m telling you this to see if the irony of our conversation is lost on you.

‘effect’.
I met the lead singer of D-Ream at Venus in Nottingham in 1994. Nice guy, although a little affected.

It’s fuck all to do with what the government tells anyone. You can literally do the proofs yourself that the earth is a fucking sphere unlike checking for WMD.
Here, do some more research and check for yourself. There’s ten simple ways that you can see without any authority figures lying to you:

Flat Earth Society meeting.
How can it possibly all fit together when middle-earth dwellers live on a flat earth?
Gravity powerful enough to hold everything to the surface yet has no hold on a helium balloon. If earth was a ball and say for example UK at the top and Australia at the bottom , if you jump feet first then how do you come out feet first on the other side of the ballGravity pulls it down towards the earth. That affect will always pull the water down. That’s why when you put water on a football it falls off towards the centre of Earth, the mass of earth being greater than that of the football.
