Do you know why cricket ball spins? Hurl a spherical stone and watch it. It will spin while traveling. The science behind it called conservation of angular momentum. The speed of object may differ due to various conditions but all the planets and stars keep spinning. The speed of spin is slowing. But the reduction is very very small. In due course after several centuries you will notice the day would be significantly longer than 24 hours.

The theory goes like this. During the formation of the earth, the gases were spinning and set in motion with the Big Bang. The conservation of angular momentum is what keeps the earth spinning. The earth is in the vacuum of space spinning since it was formed. Currently there is no force acting on the earth to stop it from spinning.

Think of a very very large freight train (say 1000 tons) rolling down the ordinary tracks at 60 MPH. If the ordinary tracks turn into "fricitonless" tracks and then you cut the train engine off, the freight train would keep going for a long long time until the friction of the air (external force) against the freight train slowed it down. This similiar to the earth's rotation about it's axis.

Well...... At one time spinning the Earth about the axis of both Venus and Mars was tried. But both of those experiments led to some incredibly complex instabilities within the Solar System, and it was decided that having it rotate about it's own axis really was an optimal solution considering all of the many factors.

HTH ☺

Due to the rotation of the earth on it's axis we are able to experience night and day. Due to the tilt of the axis and the earth's position in it's orbit around the sun we experience the seasons. This is in perfect harmony with the universe, if we were not exactly where we are in our position relative to the sun we would either fry or freeze. Big Bang Shmang, the universe was put in place by our Creator that is why it is perfectly placed. God spoke the universe into existence.

Dear Kamalesh

A wonderful question, i admit not many would know the real reason for it but here goes the actual answer.

Any object suspended in space will always try to achieve a stable shape, the most stable shape in the universe is the sphere. The only way to achive is to mould itself by rotating on its axis. This explains why all the planets are somewhat spherical.

due to geographical axis it mean that north and south magnet core are situated in opossite direction which cause to rotate about neutral axis

Depends on how you want that answered. How else can we have a day and night? Also, the entire universe is spinning, thanks to the slight imbalance that created all of the matter we see resulting from the Big Bang.

its simply coz of the initial vel tat it gained after hittin matter in space after big bang...now der is no force to arrest it n so is it still rotatin

It gives us day and night.

Maybe it stabilized our orbit? Assists in air and water currents which help sustain life?

So it won't bob up and down like a bouy.
