Put a flat earthier into space


I've just realised I've cocked up my calculation for the straight line distance between Calais and Lisbon, it's almost exactly 1000 miles, but roughly 1,600km in a straight line. The driving distance still works regardless :oops:🤦‍♂️
 
You need a map, a basic grasp of mathematics and the ability to think, so I can see why you find this difficult.
I also did the calculation for you in the post you quoted, so you asking me how I would go about calculating it shows you're not paying attention as well.
Actually, I am paying attention.
I asked you to offer them based on having nothing on a plate.

From this, I ask you about your global knowledge for distances. That's what I'm asking.
The whole point of this example is to demonstrate that we can calculate the distance between any 2 places on the planet easily with a basic knowledge of mathematics and it works absolutely consistently for any 2 places you choose to name, but that it doesn't work if the planet isn't a globe.
You can calculate distances on Earth and you're told it's a globe. You do not know this.
For example, let's take Calais and Lisbon. I'm choosing these 2 places because I have driven this journey myself and can therefore verify that what the maths tells me matches with what I personally experienced in real life. In a straight line, they're almost exactly 1,000km apart, but as that line goes over the Bay of Biscay, it's not possible to drive that route, so you end up with a driving distance of just over 2,000km. Considering the driving route has a near 400km "detour" from the most direct route, a little trigonometry will show you that even if you could drive in a straight line to the point farthest from the straight route, and then in a straight line onto Lisbon from there (spoiler, you can't) you would already be adding 280km to your journey. Factor in the bends in the roads and the 2,000km fits in nicely with the maths we did at the start.

I know this has been a waste of time as you'll just wave it away, but it's been a fun experiment to revisit GCSE maths again and use it in a real world example.
You're not offering anything for global proof and you know it.
Your turn now, how can the distance between any 2 places be calculated accurately on a flat Earth?
Probably a plane. Speed and time to a location by flying in a straight line over a level. You'll get a rough indication over distance.



You can use Calais and Lisbon as your examples if you like, but remember we then need to apply your formula to any 2 other places, perhaps Rio and Cape Town next.
As above.

How would you know how to get from Point A to B?
 
It's up to you to take from what I say, or not.
You get what you get and you have a choice.
But a picture says a 1000 words no🤷‍♂️

Trying to visualise a map is pretty difficult wouldn’t you agree?

Surely showing this would give a valid demonstration of the thought you have given to it. Don’t think anyone would knock you for the effort put into it🤷‍♂️

No, I said these were the calculations based on a global model, if these calculations are incorrect, you would notice when you tried to travel between the 2 places you had calculated that it was wrong. Hence in the 2nd example, I picked 2 places I had personally travelled between. I know how important it is to you to verify it first hand.

This was going to be my next question, if I wanted to fly direct from Calais to Lisbon to verify the straight line distance, how do I know which way to point my plane? Some sort of map presumably.

Now, you haven't offered a way to calculate the distance between 2 places that works on a flat Earth, so your turn.

But you aren't basing them on a global reality, you are following a global model mindset on paper.

Yep, but what sort of map? Your map is based on a globe and your distances are based entirely on that.
Other than that you have no clue you're doing anything other than following a straight line. Point to point but under the impression of using a great circle.
Now, you haven't offered a way to calculate the distance between 2 places that works on a flat Earth, so your turn.
There's stuff on the internet I could bring up to calculate for flat or globe. It's no offering to you or me as to the reality of anything, so why bother?
 
Was the carbon arc malarkey not his?

No that came from that 200-year-old book as well, I think.

You get what you get and you have a choice.

Well, so far you've given us absolutely nothing to make us even slightly doubt the smallest of details about the globe earth, maths, physics, gravity or anything else you've talked about on this thread.
