I explained it some months ago and you stopped bothering me with the craziness, now like all craziness it is coming back.
As I recall faster moving jets are colliding with slower moving jets that were ejected previously.
No, you did not.
Gravity cosmology cannot explain the jets, cannot explain how it holds together, nor can they explain the bilateral symmetry. They cannot explain any of the features seen inside what they refer to as "hot gases," why they are hot, or explain why it radiates in the x-Ray ranges. They cannot explain why they are everywhere they look in the sky. If they were what they claim, they'd be very rare. They are not. They are common. They fly in the face of standard gravity laws and Boyle's Law of how gases act when uncontained. They are at a complete loss to explain any of it. The use ad hoc claims that do not hold up to examination. They cannot even begin to explain any of it.
