    The circumference of the Earth at the equator is 25,000 miles. The Earth rotates in about 24 hours. Therefore, if you were to hang above the surface of the Earth at the equator without moving, you would see 25,000 miles pass by in 24 hours, at a speed of 25000/24 or just over 1000 miles per hour.

    Multiply by cosine of your latitude to see how fast the Earth is rotating where you are.

    Earth is also moving around the Sun at about 67,000 miles per hour.

    i dont know physics but im educate enough to understand this is bullshit. and if a person say this is true i can only laugh for him

    This is what happens when you dont do one thing ryt. either you stick to it and become educated or leave studying to smarter goys. you'd laugh coz u aint got a clue bro.......

    tell you what check this link

    and there look for these exact words

    "To summarise:

    No, it doesn't show the rotation of the earth.
    No, it doesn't show the curvature of the earth.
    No, you don't need to be very high to see either of those."

    If by "turning" you mean the rotation of the Earth about its axis (where axis just means the straight line between the North and South poles) it is quite easy to figure out how fast any part of the Earth's surface is moving.

    The Earth rotates once in a few minutes under a day (23 hours 56 minutes 04. 09053 seconds). This is called the sidereal period (which means the period relative to stars). The sidereal period is not exactly equal to a day because by the time the Earth has rotated once, it has also moved a little in its orbit around the Sun, so it has to keep rotating for about another 4 minutes before the Sun seems to be back in the same place in the sky that it was in exactly a day before.

    An object on the Earth's equator will travel once around the Earth's circumference (40,075.036 kilometers) each sidereal day. So if you divide that distance by the time taken, you will get the speed. An object at one of the poles has hardly any speed due to the Earth's rotation. (A spot on a rod one centimeter in circumference for example, stuck vertically in the ice exactly at a pole would have a speed of one centimeter per day!). The speed due to rotation at any other point on the Earth can be calculated by multiplying the speed at the equator by the cosine of the latitude of the point. (If you are not familiar with cosines, I wouldn't worry about that now, but if you can find a pocket calculator which has a cosine button you might like to try taking the cosine of your own latitude and multiplying that by the rotation speed at the equator to get your own current speed due to rotation!).

    The Earth is doing a lot more than rotating, although that is certainly the motion we notice most, because day follows night as a result. We also orbit the Sun once a year. The circumference of the Earth's orbit is about 940 million kilometers, so if you divide that by the hours in a year you will get our orbital speed in kilometers per hour. We are also moving with the Sun around the center of our galaxy and moving with our galaxy as it drifts through intergalactic space!


    enough?

    and i never said the tower needs to be tall as the width of earth, thanks :P

    you never said it but thats what you meant. im actually speaking of the nose and you speak about an eye to make it simple to you.......we are on different pages. keep going but im off. peace out..........:P

    no i didnt mean it. i know the tower dont have to be tall as earth, i just wanted to show when its compared to tall of the building and width a of the earth anyyone can find this is impossible. yea this is so simple to understand. its fake

    Guyz let make this clear,anyone hv u been to there? if the answer is no, plz dont make arguments without a clue.

    That particular photo has taken by using fisheye effect,which am also agreed. but the story behind that last photo has something real interesting.
    Am not believing that anyone could see half of the earth from the top of this tower.

    However, we could see the curvature of the horizon clearly from it.
    human eye is also functioning as a lense,therefore I think when the focal point touched the horizon its illuminates as a curvature.
    That's why most of the ppl saying that earths curvature can be seen at top of the Burj Khalifa.

    Finally, I heard the above facts i mentioned here from a Architecture who's visited there for a technical work.
