Mechanism of the Dark Matter and Condensed Bubble Objects Formation in   the Model of Extended Space
  Within the framework of Extended Space Model (ESM) the processes connected to birth of photons in a gravitational field are studied. These photons have a nonzero mass. It can be both positive, and negative, and photon's energy and strength of the gravitational field determine its absolute value. It is shown that in ESM model formation of bubble gravitational structures is possible. In the frame of ESM one can obtain the follow physical picture. Bubble gravitational objects have a halo formed by dark matter generated by photons with a positive mass. The photons with a negative mass are throw away in free deep space and create there antigravitating vacuum with negative pressure. The comparison ESM bubble structures with similar objects of a type "gravastar", existing in a General Theory of Relativity (GR) is made.
