The myth about origin of planets from proto-planetary cloud, started by P. S. Laplace in attempt "to improve" Kant's concept in 18-th century, is changed in the beginning of 20-th century into Jeans's mathematical theory gravitational collapse. This myth has taken possession of astrophysicists minds for the whole century, despite of unfitness of its positions with realities of the Space.

First, there is no pressure in the Space. There is high vacuum. Even having final density, cosmic "gas" from atoms of hydrogen and helium is not gas in that sense, which is used for gases in laboratory conditions. Having equilibrium with aether temperature about 3ºK atoms of hydrogen and helium practically do not collide in extragalactic space and in interspaces between galactic arms.

Therefore Jeans's hypothesis about the beginning of stellar evolution from huge proto-stars in "early universe" does not pass. More so, the concept of "early universe" is false. There was no any "Big Bang" and "early hot universe" with the first stars 13 billions years ago.

The Universe is practically steady-state during many thousand billions years. The stars are forming constantly, as in the far past, and today.

The other question is how it occurs? What is supplier of their mass? What power sources of their emission? Let's try to answer these questions.
