The difference between virtual and real particles.
Virtual Particles are like a “speculative tract, that might have existed”. ( — hence virtual particles are needed to satisfy consistencies of probability factors or likelihood fractions in a particle physics calculation, so that the consistencies of Physical laws can be maintained ) Real particle must exist; Real particles make real effects and virtual particles…

a simple calculation for earth spin projected onto sun-earth orbit plane.
Here is the earth-around-sun and earth-spin situation: Earth rotates around sun in a tilt of 23.5 degrees and earth rotates around itself with spin S. SO S is 84% along sun’s vertical and 16% along sun’s horizontal;

The equation of motion in General theory of Relativity
In theory of Gravity: the equation of motion is determined by the gravitational field, like in our Newtonian theory a field/force when solved in terms of space and time coordinates gives a differential equation called a equation of motion whose solution gives you the trajectory of motion. In Gravity theory the equation of motion in…

A simple calculation of earth’s orbital speed around sun
From speed of light, time of flight of light from sun to earth, the orbital speed of earth around sun comes out to be ~33 km/s. You can adjust the speed of light and its TOF to get a more confirming value. (~30 km/s)
