Question: I read conflicting information on why Earth spins and has done so for millions of years with very little speed change.
Some say it’s due to cosmic spinning particles millions of years ago others say it spins due to collisions in space and some say it remains spinning from the big bag etc.
May be its just my lack of understanding but none of these seem to hold up to me or make much sense.
Could it be the Earth settled in orbit around the sun and then over millions of years began to rotate because the sun heating one surface and the dark side getting colder and colder hence eventually heat diffusing from the hot service and air to the cold service and air mixed with the orbit of the sun caused the Earth to start rotating.
If so at this time it would have spun up quickly in space terms until the temperature of both sides settled down.
Now in this day during the period the earth’s surface is exposed to the suns radiation that surface area (sea or land) and the air above it becomes warmer and warmer until it falls back into darkness (night) and begins to cool, the coldest part that has been in the dark the longest is now being attracted to the warming sun facing surface (morning).
In a vacuum such as space surely this well known heat reaction could over millions of years cause Earth to continue to rotate and remain rotating at its fairly constant speed.
If my theory is correct then someone better at maths than me could proof this by looking at the rotation speed of Earth and calculating the period the suns radiation is on the surface, mass of the Earth and distance from the sun, my maths is not good but I hope you understand what I am saying here.
So if the Earth is in fact rotated by heat diffusing from the hot air to the cold air then this would have a lot of implications such as calculating service temperatures of celestial bodies including the sun and planets, deterring what elements may exists, estimating mass, distance from the sun etc
So could it be rotation has existed for so many years due to the simple physics of heat exchange?
I don't pretend to understand astrophysics, so could someone tell me if this theory is even possible.
Thank you for your time
