Not really. They can't even see the entire Earth, because a sphere isn't fully visible from any perspective at any distance. It isn't a sphere anyway - it's an oblate spheroid.
The fact that the Pole Star appears higher in the sky as you move towards the North Pole and lower as you move towards the equator indicates that the Earth is curved. The only shape that fits this observation is a sphere.
A boat at sea, alone, does not prove that is earth is round. However, boats can be used to prove that earth is round. This is because if the earth was flat, eventually a boat would sail to the end of earth and fall off the edge. This has never happened, so it can be inferred that the earth is round. Also, a boat can sail all the way around the world and end up right where it started, which proves that the earth is round.
The needs that led to the development of the artificial satellite and the transistor during the Cold War included the high unemployment of the Americans estimated then to be about 14 million, and the need to prove to the world that Americans were innovative.
We observe planets, moons, comets, and artificial satellites and space probes moving in relation to the central body within their orbits exactly as we would expect them to move if the theory of universal gravitation is true. This evidence supports the theory of force at a distance due to universal gravitation, but doesn't prove it. It's still "only a theory", which can never be proven, but can be disproven in half-a-second if we ever see a situation where it's not working that way.
One way to prove that the Earth rotates on its axis is through the Coriolis effect, which causes moving objects to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This effect is observed in phenomena such as the rotation of hurricanes and the direction of ocean currents. Additionally, the Foucault pendulum demonstrates the Earth's rotation by gradually changing its orientation as it swings back and forth.
how can you prove that earth is a sphere by looking at the pole st

An isochronous satellite is one that orbits the earth in one day. So it orbits the earth as the same speed as the earth rotates. Most satellites that are isochronous are infact geostationary satellites as they also stay in the same position above the earth. However these satellites occupy a very specific orbit above the equator. It is possible to have isochronous satellites that aren't geostationary however getting them to remain in orbit would prove difficult.
Horizon observation: If you observe a ship sailing away, you will notice that its hull disappears before the top of the mast, indicating the curvature of the Earth. Satellites: Images from satellites show the Earth as a spherical shape. Space travel: Astronauts have viewed the Earth from space and confirmed its roundness.
Magellan's sailors proved one of Aristotle's theories by circumnavigating the Earth, which demonstrated that the Earth is a sphere. This contradicted the prevailing belief at the time that the Earth was flat.
Given that we have satellite pictures of Earth now to prove that it's a sphere, you'd have to be willfully ignorant to believe it's anywhere other than about 6000 km below your feet.
Now you can look at pictures - in the old days you could watch ships disappear over the horizon.
This Might Not Prove It But Let's Say Your Friend Likes Travel,What Would They Say?They Would Say"Soon,I'm Gonna Travel All AROUND The Earth"They Don't Say"Soon,I'm Gonna Travel All Flat The Earth,Or Skinny The Earth,Or Thin The Earth"Like It Don't Work Like That,Like I Said,This Might Not Prove Anything,But Think About It
that the earth is round just like what Magellan said ... `The church says the earth is flat, but I know that it is round, for I have seen the shadow on the moon, and I have more faith in a shadow than in the church"
I can prove there are angels on earth.. trust in god and he will prove it to you too.
Columbus originally was determined to prove that
I have no Idea man. Or Girl, whatever you are. JK!! He sailed across the world with his crew and didn't fall of the earth, he went forward and back. Sorry about the start.
