Is it true that the " geographical centrepoint of Earth " is at the Great Pyramid of Giza in Egypt ?

    I don't see how there can be a center of the surface of a sphere.  The center of the earth, yes, deep inside the earth.  But the center of the surface?  That's a little arbitrary.

    The world map as we know it is drawn by Europeans.  They see Asia to the east and the New World to the west.  But if the map was drawn by the Japanese, Japan would be in the middle, Asia would be to the west and the Americas would be on the eastern edge!

    Also, as the world population shifts, the center moves.  It's only been about a century since the Great Pyramid was named the center of the earth, and in 100 years there probably hasn't been much of a shift.  But there certainly has been in the thousands of years since the pyramid was built.

    No.  The only fairly fixed geographical point on Earth's surface that everyone can measure or agree upon is at the South Pole Station in Antarctica.  A slight offset or wandering of the spot happens over time, but is not too wide right now.

    The other end of the earth's rotational axis is in the Arctic Ocean.  Not much access or stability there.

    Do you mean like a baricenter.

    It looks as if none of the other answerers actually read the Wikipedia article in the link. If you read it, you'll see what the definition of "Geographical centre-point" is, and the various criticisms that have been made of the original definition that located the point as Giza. You'll also see that Google Maps does mark a "geographical centre-point" but it's quite far away from Giza. So no, space aliens did not build the Great Pyramid.

      :) Space aliens able to reach the solar system would have recognized the results of plate tectonics and not even bothered to mark something as changeful as a geographical center of our planet.

    If the earth is an approximate sphere, it is not meaningful to talk of a centre point on its surface. There is no such thing as the centre point of the surface of a sphere.

    If someone were to calculate the centre point of the planet (either by distance from the surface or by gravity) an infinite number of lines could be drawn through that point to intersect with every place on the surface.

    An arbitrary projection of the surface of the earth onto a flat plane may have an equally arbitrary centre point but if you create your arbitrary map from a different perspective, there would be a different arbitrary centre point. Giza may well be one arbitrary centre point on one arbitrary projection of the world map. That does not make it meaningful in any way.

    It is a meaningless distinction. If all surface land is considered a uniformly thick shell, and a center of gravity is calculated only based on this shell, this center will be found deep below the earth, but not at the exact center of the earth. If a line is drawn from that off center point to the surface of the earth, it goes through Egypt.

    It's just a made up name for nothing, and I'm guessing the exact point is no way near the Pyramid of Giza, only approximately and that is usually good enough for tin foil hats. =)
