    "abstract": "Within the framework of Extended Space Model (ESM) the processes connected to\nbirth of photons in a gravitational field are studied. These photons have a\nnonzero mass. It can be both positive, and negative, and photon\u0027s energy and\nstrength of the gravitational field determine its absolute value. It is shown\nthat in ESM model formation of bubble gravitational structures is possible. In\nthe frame of ESM one can obtain the follow physical picture. Bubble\ngravitational objects have a halo formed by dark matter generated by photons\nwith a positive mass. The photons with a negative mass are throw away in free\ndeep space and create there antigravitating vacuum with negative pressure. The\ncomparison ESM bubble structures with similar objects of a type \"gravastar\",\nexisting in a General Theory of Relativity (GR) is made.",
