The science will be pretty straightforward until I mention the fact that gravity has energy. At present this isn’t considered in physics.
The basic reasoning http://Gravitational Energy | Encyclopedia.com https://share.google/kRTlt7yg8uwnZsiWh
The maths will show that the faster the Earth spins, the less the Sun’s orbital gravity can push the Earth. With energy, it is often quantity as KE = 1/2mv^2. This is a linear value. If that body is the Earth then its spin is also KE = 1/2mv^2 giving the Earth’s angular momentum energy.
This kinetic energy can be stored in the Earth as potential energy slowly released over a 90,000 to 100,000 year ice age cycle. It does seem likely that the glaciers during an actual ice age don’t see the Sun. Yet the Earth can quickly adapt to a faster spin because of the sudden onset of a Full On ice age.
This is based on Newton’s gravity which is also
With this, the Sun’s mass is 1.989 x 10^30 kg.
“G” is the Universal Constant and it has a value of 6.674 x 10-11. This is the “push” that planets and satellites receive to stay in orbit.
There’s also inertia which is calculated I = mr^2
This omits velocity which determines force. Also there’s g = Gm/r^2. Then this will help to show how the spin of the Earth influences how much the Sun’s gravity “pushes” it with its orbital gravity.
With the Earth, it’s mass is 5.972 x 10^24 kg. The Moon’s mass is 7.347 x 10^22 kg. Einstein’s gravity well is located between the Earth and Moon using the equation g = Gm1/r12 > 2a < Gm2/r2^2.
This point might allow for the Earth and Moon to be calculated as a variable because of the wobble this allows for. What will be important to note is the change in the Earth’s orbit relative to solar Irradiance. With a value of about 1 w/m^2 would suggest that more than solar radiation contributed to the global temperature. Joseph Fourier said in 1827(?) that the Earth is too far from the Sun to be warmed by the Sun. Friction between atmospheric gasses could help to explain this.
