Is the world really round?

Well technically it's elliptical, but yes it's a big ol' globe.

1. Eclipses, and lunar phases. \n2. The other "celestial" bodies, like the sun, moon and planets also appear round. One might assume, that the earth might be also.  \n3. Gravitational laws based on the earth being a certain shape and size, predict movement, etc. \n4. The stars in the southern hemisphere are  different than in the northern hemisphere.\nIf the earth was flat, one should be able to see the all of the stars at least some of the time. \n5. Sailors regularly circumnavagate the earth.\n6. Planes regularly fly around the world.\n7. The seasons and the climatic zones are hard to explain otherwise. \n8. The coreolis forces of hurricanes.\n\nOne can use scientific method to prove all of these and come up with conclusions for an earth that is somewhat round in shape, if one isnt lucky enough to see it from space, and believe it with your own eyes.

No, I think it's relatively easy to believe.  As a sentient species our past has been riddled with assumptions of the cosmos.  In reality, what we usually find is that the nature of the cosmos is far from what we assume and often counter intuitive.  Take the world is flat perception:  from the ground looking out into the ocean, it would be easy to assume that the Earth was flat, as the horizon looks like it ends and you would fall off the planet.  Also looking at how the sun is at different points in the sky during the day, it would also be easy to assume that the sun orbits the Earth.  Grand assumptions on behalf of humanity are not new.  If the Universe continues to expand, it could just be the limited intelligence of our species which fails to comprehend that our Universe can expand as far as we are concerned, there is literally nothing beyond the edge.

it is a complete hoax. nothing humans do can tilt the axis of the planet. all human cities are like weigh like 0.01% of an average mountain range.

The earth is round because matter attracts other matter, and when they get close they compact together to form spherical objects.\n\nPeople created computers because they kept asking why.\n\nEinstein created an atom bomb because he kept asking why.\n\npeople believe in god because they couldn't figure out why any other way.\n\nThere is music becuase people created it.\n\nPeople have brain because our genetic makeup conducts brain building and reconstruction for our entire lives.\n\nHope that answered your questions

They say that love makes the world go round and I tend to agree ... it certainly makes my world go round ... but it you are looking for a scientific explanation, these sites may be of some help  ....

The earth is round and its gravitational pull draws us to its center.  Upside-down is really just pointing away from the core...from anywhere.

is this the real world?

WHEN YOU ARE ON EARTH U CANT FIND ANY POINT. YEAH I THING IS POSSIBLE. U CAN PURCHASE A GLOBE AND ROTATE IT. U WILL FIND ROTATION THERE.!

"That's the way that the world goes round"

The earth isn't round. It's a squashed sphere, due to it's rotation.\n\nI wish grass fell from the sky. I have to go find a guy who knows a guy to get my grass.

Yes, it is possible. There is only one case where it is impossible: all three circles have the same radius & their centers all lie on a straight line.

Not quite. It's shaped like a pear. We call it a Geoid.

The Ancient Greeks knew the world was round.  Their work in mathematics and geography allowed them to calculate the approximate curvature and circumference of the Earth.  The Romans also knew the world was round.  So much of the information from the Classical world was destroyed either during the burning of the library at Alexandria or during the many purges and book-burnings of the Dark Ages.  Much more information was hidden by the Church and forbidden.  Both the Renaissance and the Age of Exploration were about a return to the enlightened times of Classical Europe.  Christopher Columbus theorized that the Earth was not flat, and attempted to sail to Asia in 1492.  He thought he had reached Asia, but it turns out that the Earth was much larger than expected.  He simply re-discovered the Western Hemisphere.

Is it round?  This is due to gravity.  Gravity pulls with equal strength in all directions; therefore any variations from a spherical shape will lead to gravitational forces that bring the shape back into that of a sphere.\n \nThis is without considering the rotation of the earth, however.  The rotation of the earth adds centrifugal effects, which cause the earth to bulge slightly at its equator and flatten slightly at its poles.  (This is like twirling a rock on the end of a string and then letting go--the rock flies away from the twirler.)  Because of these centrifugal effects, the distance from the center of the earth to the surface of the earth is about 0.33% shorter at the poles compared to the equator.

It is not just round or oval. It is elliptical. One side is close to the sun and one side is closer to the Oort Cloud, or Kuiper Belt, or maybe the heliosphere, the end of the sun's influence to the galaxy.

i am round\nlike earth
