If you are at the center of the earth, gravity is zero because all the mass around you is pulling “up” (every direction there is up!). A few of other points concerning gravity: You got one of them – the fact that gravity increases as you get closer to the center of mass, because the earth is flattened at the poles.

9.8 m/s2

At the centre of Earth, the force due to upper half of the Earth will cancel the force due to lower half. Therefore, when F=0, then g has to be 0. Thus, the value of g is zero at the centre of Earth.

In general, gravity also gets stronger as you get closer to the center of a massive object, but it turns out that the effect of having less mass closer to the center than you are is more important. At the exact center of the Earth, the gravitational field is actually zero.

Because the mass of the Earth is two orders of magnitude greater than the mass of the Moon, the centre of gravity of the Earth-Moon system actually lies within the body of the Earth; indeed, it is around 1700 km below the surface of the Earth.

The strength of gravity at the center of earth is zero because there are equal amounts of matter in all directions, all exerting an equal gravitational pull. With such thick air, you eventually lose momentum and stop your yo-yo motion about the center of the earth. You end up stuck floating at the center of the earth.

it isn’t the centre of the Earth. Earth is round. If people from all over the earth turn towards a point known as Kaaba, it becomes centre for all those who prostrate towards it. Physically, you cannot pinpoint a centre on earth or for Kaaba.

Starting from the earth shapes are flat globe and elliptical, besides that the center of the earth in the North Pole, Mecca, the core of the earth even in the archipelago (Indonesia).

Originally Answered: Do airplanes or birds fly over the Kaaba in Mecca? Planes are not permitted to fly over Kaaba to prevent any attacks which have been happening recently. Birds do fly over Kaaba and don’t pose a risk of any attacks.

No planes fly over the Holy Kaaba because there is no airport in the city of Makkah. The third reason for not allowing planes to fly over the Holy Kaaba and Makkah is that Non-Muslims are not allowed to travel to Makkah. If you allow airplanes to travel, there would be many Non-Muslims crossing Makkah in air.

Khadija

Anas bin Malik ibn Nadar al-Khazraji Al-Ansari (Arabic: أنس بن مالك الخزرجي الأنصاري‎, c. 612-712[citation needed], or died 709[1]) was a well-known sahabi (companion) of the Islamic prophet Muhammad.

al-Aʻlā (Arabic: الأعلى‎, “The Most High”, “Glory To Your Lord In The Highest”) is the eighty-seventh chapter (surah) of the Qur’an with 19 verses (ayat).

The history of the spread of Islam spans about 1,400 years.

There are many reasons why Islam spread so quickly. First Mecca was connected to many global trade routes. Another important reason was their military conquered lots of territory. While all three factors are important, it was Mecca’s connection to global trade routes that helped to spread the religion the most.

Waḥy (Arabic: وَحْي‎, IPA: [waħj]; plural وُحِيّ wuḥiyy, IPA: [wuħijj]; also spelled wahi) is the Arabic word for revelation. In Islamic belief, revelations are God’s Word delivered by his chosen individuals – known as Messenger prophets – to mankind.
