What REAL proof do we have that the Earth is round?

Question

Let's face it, the photos that have been sent back from satellites are pretty ropey at best. I mean, if you got your photos developed and they looked as blurry as NASAs photos, you'd ask for your money back right?

So how can we be SURE that all the lands of Earth aren't just repeatedly endlessly? That, if you keep heading East (or West), you won't come back to the same place, but instead you'll end up in a place that is SO SIMILAR to the place you took off from that you can't tell the difference.

Obviously in the place you arrive, there would be all the same people as well, including an alternate version of you who also went heading East (or West).

Do you think this could explain why some days you feel like you're just in the wrong place?

Answer 1

God who created the earth said so. That is the best proof - The Maker. Isaiah 40:22

Also other sources like the norwegian textbook written in 1250, gave the varying climates of the earth, the angle of the sun at different times of the year and the prevailing winds

The ancient people like pythagoras asserted to the earth's roundness.

Go and make researches based on the writings and experiences of theses and others - perhaps your own. These examples doesnt state a complete roundness, usually spherical

Answer 2

I was wondering if you could settle a bet. My friend, who is a
philosophy major, says the earth is flat. I say it's round. He's
telling me the premises for determining that the earth is round are
false. How can I explain, using math (he will agree with Pi = 3.14,
simple trig and geometry, and standard definitions of distance) that:

1) The earth has a definite curvature (sp)
2) One can determine a general position on earth fixing with
stellar points
3) The circumference of the earth ( In km )
4) And prove that the earth is round

I remember from high-school trig that it is possible (using a
sextant) but if you could provide some general theories, I would
appreciate it.

Also within those parameters I can't use items like pictures because
they can be forged.

Yes, he is a candidate for the flat earth society.
Thanks.

Hi,

You cannot prove that the Earth is round or flat using mathematics.

Mathematics does not answer questions about the way the world is.
Your question is a physics question.

While it is true that much physics uses mathematics, and it is quite
wonderful that this is so, nevertheless, mathematics is not really
concerned with the physical world. This has the happy corollary that
mathematics is not bound by physical laws.

In any case, to address your question, we can ask what is meant when
one asserts that the "Earth is flat," or the "Earth is round." Both
statements are a model of reality. Demanding to know which of the two
is really true does begin to border on the philosophical, but in terms
of practicality, one of the two models may serve to promote
understanding of numerous facts... such as that Columbus never fell
off an edge of the world.

If you can provide a simple principle which explains many things,
you make it easier for people to do things. For example, no one will
ever really know if there really is a gravitational inverse square
law, but it has proven a wonderful model which enabled people to get
Neil Armstrong to the moon.

Besides, on closer inspection, both models of the Earth are likely
false, as anyone who's tried to hike up a mountain can testify.

I think that enough for you

Answer 3

Go to the ocean to watch a ship sail off into the distance. You can use binoculars or a telescope. You'll notice that as it becomes more distant, it will start to disappear over the horizon. First the hull will gradually disappear, leaving the sail, which will also sink below the horizon, until just the tip of the sail remains, and then it too will disappear. This is because the ship is moving over the curvature of the earth, and being hidden by the earth (seas) between you and the ship.

If the world was flat, the ship would simply seem to shrink as it got farther away, and while it would eventually disappear from your perception, a more powerful telescope could be used and you would be able to see it again.

There are more mathematical ways to prove the Earth is round, but this one is easy to understand, and if you live near large enough body of water, is something you try for yourself.

Answer 4

My first cousins great grand metarnal uncle was a researcher in just this phenomenon called, "Globoroundoflatowhatology"
He has published a book called the " Effects of Hexagonal orbits"
and has clearly proved using scientific data that the earth is flat
until the horizon and is flat after the horizon if and when u reach it.
Also the principle of relativity is based only upon his conclusions.
The geo physicist Mr Digitacross has proved that if u dig the earth to a depth of 17,945, miles you will come into a time warp wherein your great grandfather will recieve you.This experiment was also called, " Digtherig_a_s_s_h_o_l_fora122ears"

Answer 5

Phileas Fogg went Around the World in 80 Days, he didn't go aflat the world in 80 days...

Jules Verne is rarely wrong, dinosaurs DO live in the centre of the earth too...

Answer 6

Science can only make round the earth. Earth is not round.

Answer 7

that is an interesting theory but i think when your feeling off it's because you slipped into The 4th dimension for just a second and it throws you all outs whack

Answer 8

The earth is not round. And it's not oval either. It's an oblate spheroid.

Answer 9

i think the earth is an octagon.

one time, i was running from one end of the earth to the other and i ran into george bush, you know what he said? 'whatup'.

true story.

Answer 10

The Earth isn't round.It is oval.So why bother to ask proof for something that isn't true?
