The total mass of Galaxy is about 2x10⁴¹ kg.

4 billion sun masses should be in the area of the galaxy core: 8x10³⁶ kg. They are falling into the center, forming PK, which will carry away its gravitational part at this central mass of the Divergent Sphere. Nobody knows exactly how much mass is there. Perhaps there are 2/3 of the core-mass? Let's simply take half of it: 4x10³⁶ kg. This PK has the amplitude of Ro=2.97x10⁹ m. Until the opening of its horizon, two times the amplitude and 1.125 of the gravitational radius must have gone: 2.25 Ro, these are r = 6.7x10⁹ m. Its subs aren't moving at a straight line of half-period, but on bows. Consequently, at least the circular orbit of u = p r is necessary, u = 2.2x10¹⁰ m. Sub-PK, if they would fly nearly v to c, would need 72 seconds for this way. The PK exists about 70 s then. During this time, its mass isn't 4x10³⁶ kg any more, but 1.24x10^-52 kg. This mass is really off of that place. But, how long doesn't the PK exist any more after its opening (after its anticollapse), how long it stays opened until the next collapse, this is absolutely unknown. The time is dependent on the falling velocity of the falling stars, which cannot have reached v to c. I think about 1/100c, so that the time of opening is about two hours long (the sun-surface vibrates all the 2 hours; is this relevant or coupled with it? a kind of tidal power caused by the center of Galaxy?). It can be more.

We have to search for this: Gravitation of Galaxy core will be less after some hours periodically for the time period of about 1 minute. This gravitational line you should be able to measure.

Pulsating period of pulsars is also dependent on the opening of their PK pairs, which are created in the center of the Divergent Sphere. Ever after, how much mass rotates around the pulsar-PK and how fast it rotates already, the phase of opening and so the frequency will be determined. Pulsars are forming themselves from Supernovae of bigger stars, of so-called giant stars. They have at least 10,000 sun-masses. These are at the minimum: 2x10³⁵ kg. From the SN the biggest part of mass is ejected as shell. In the central PK of the following pulsar, about 1/1000 up to 1/100 of the mass remain, so estimated in the middle: 4x10³² kg. Here the amplitude Ro is » 3x10⁵ m. The existence time then is about 7x10^-3 seconds, rounded up to 0.01 s. The pulsar in Crab-Nebula pulsates with 0.03 s. This number matches the minimum very well, assessed by me.

Obviously, the time of opening of pulsar-PK perhaps is 3 to 5 times as long as half the period time of the PK. Surely, the reason is the environment-mass at the surface of the pulsar-PK, which is just falling with already 1/5 c up to next to c (vacuum light velocity c) while opening.

Sun-PK pairs just should be mites, which has been formed out in sun center (Divergent Sphere) as rest of so-called "degenerated matter" after Enrico Fermi. Perhaps there are hold 1/1000 of the sun's mass, or more? These are at the minimum: 2x10²⁷ kg. The existence-time of sun-PK is then about 10^-10 seconds. Imperceptible for us! The gravitation of the Sun is vibrating with smallest parts of seconds! Because of the high particle's pressure in such a small center of the sun, the particles should fall back into these open PKs with next to light speed. This way, the pulsation will be next to 10¹⁰ Hz, at 10 GHz. Is this relevant? A gravitational wave of 10 GHz has influence of the movement of the electrons at a receiver just an e.m. wave of this frequency, but here smaller with the factor of 10²⁰ because their mass is moved. Who would ever have been supposed to discover this by chance?
