When is a tail merely a tale???
Heres a little tale of mine.
The comet is not moving, this planet is not moving, neither is the moon or sun etc etc.
What is moving in continuum is the duality of spin that enables creation.
Commonly called Birkeland currents.
Imagine that the tail of the comet is where one giant such dual spinning Birkeland current is travelling, and what it creates is light as a stress in the substance of the omni present universe.
There is no light from the sun, light and heat variations are consequences of stress created where these Birkeland currents cross.
Our dominant senses and indoctrination TALES demand that the comet is zooming along leaving some form of debris tale.
Nothing actually exists, and what is created there in 3D is a by product of compression of memory into 3D, as are the physical us here, and this planet.
