Here's another one for you and the orthodox cosmologists to explain using only gravity. This one is called the "Ant Nebula."
Everything we see here is explicable by using Plasma physics mathematics which comport exceedingly well with reality without invoking magical dark matter and dark energy which no one can find, no matter how hard they look. NOTHING in these objects is explicable by solely using gravity as an explanation. The Butterfly Nebula even shows classic Plasmoids on both sides. These are easily reproducible in the plasma laboratory. The orthodox cosmologists are still grasping (and gasping) and trying to come up with a cogent explanation at how these can occur under a gravity model.
Gravity, as far as we know, is a spherical, non-polarly oriented force, operating equally on everything within its field with equal opportunity, yet both of these objects we see polarity and non-equality in spades. Explanations are not forthcoming from the orthodox cosmologists that make any kind of sense.
How about you tell us how these objects came to be, using purely gravity as a modality?
Neither can orthodox cosmologists explain any of the Herbig Haro objects which can reach up to 70 light years in length. This one is a good example, showing the spiraling filamentary structure:
Astronomers say they are created by "spinning jets of hot gases," but have absolutely no explanation how these "hot gases" somehow avoid Boyle's Law and stay cohesive over trillions of miles, or how they seem to spiral around a central core.
How about YOU taking a stab at it?
Oh, wait, you don't explain. You are the essence of the type this article is about. . .
