Hi.

Ty for the link.awesome.

(Will read only in the first time here.)

rise

try to draw the stellar constellations and compare these drawings to those you (or a friend) makes on the southern hemisphere. Then compare both to the drawings you can make in equatorial regions.

just make that experiment. it is the scientific method. watch and make observations, then make your own theories, and compare the theories to new experiments & observations.

the night sky (without clouds)

only use eyes, you dont even need binoculars.

yeah

no hypothesis. just draw what you can see, and then travel, make the same drawings and then compare both.

or ask a friend in these regions to make the drawings

science starts with observation.

always.

The goal is of course to understand how the stellar constellations are connected, and what their form is.

to make a hypothesis, you need to first make your observations.

yes.

To make any hypothesis, you need data first.

Of course you can start with a hypothesis, but i proposed it this way, so that your experiment is unbiased.

(like a randomized study)

as i said.

the experiment is the step after you formed your hypothesis (after you made the initial observation).

i agree.

but you need a complete observation to formulate your hypothesis correctly.

not just partial data

or, several data points.

if you have 3 points of observation, you should be able to make a pretty accurate model

you need to view it from different.... angles

ok , 2 observations could be enough to formulate a crude hypothesis

one from north, one from south

the problem here is, you dont make *any* assumptions before your observations, so you have to check if the hypothesis could be refuted, by making a second observation, from a different place

ok, lets assume you would make the hypothesis that earth is flat, after you make the first observation of the star sky. you now want to check if that hypothesis is true or false? what would you propose to check it?

Science tries to research the form of things, not only how they work.

So how would you prove your hypothesis, that earth is flat?

And how would it be refuted?

a proof would be if the star sky is also flat.

that means, constellations would look the same from any location on earth.

How do you explain that airplanes need (roughly) the same time to fly australia_africa and south-east-asia_north-america?

@jeremy

(the question is for him)

(i'm on your side, refuel meee)

Do you mute everyone who refutes flat earth? ^^

Btw. the tides also prove that gravity exists.

If there was no gravity, the moon would leave its orbit.

and also we would float into the air

Ok. How have you been convinced that earth is flat?

the heliocentric model is not 100% correct, because the sun is not at the center of the universe.

it is only the center of our solar system.

not

So have you made the observations? And what did you see.
