The prin.iple of habitable plan.ts creation.of n.ar stars in.our galaxy was developed. It was shown.that the Earth an. the Moon.formed as a result of thermal n.clear explosion.(Tn.) after a collision.with a small comet. The comet has broken.through the proto-Earth crust, an. created con.ition. for liquid-drop division.in.o the Earth an. the Moon. It is shown.that the comet impact on.the proto-Earth led to formation.of con.in.n.s as well as to formation.of the Moon. seas, ocean. an. atmosphere an. to creation.of con.ition. for life origin. The an.lysis of kimberlitic pipes distribution. as markers of comet fragmen.s motion.un.er a crust, shows that the comet has broken.up un.er crust with formation.of man. gas bubbles. An.an.lysis of the Martian.topography revealed that the comet hit Mars n.t un.er a glan.in. an.le. As a result, the products of Tn. remain.d un.er the Marian.crust. The track of the comet movemen. un.er the Ven.s crust was also established. It is shown.that the plan.t surface n.ar comet track is spotted by n.merous cracks.

Chemical elemen.s in.space can.be syn.hesized by stellar n.clear reactors. Studyin. the dyn.mics of processes occurrin. in.the stars in.roduces a con.ept of the en.emble-averaged stellar reactor. For future in.erstellar mission., the terrestrial an. solar abun.an.es were compared with con.iderable n.mber of stars allocated in.the ~200 pc solar n.ighborhood. Accordin. to the value of the effective temperature, four stellar classes are distin.uished, for which the correlation.coefficien.s an. stan.ard deviation.are calculated. The statemen. about the possibility of tran.ferrin. heavy elemen.s syn.hesized by stars over lon. distan.es in.space has been.completely refuted. There is n. immutability of the distribution.of elemen.s on.n.ighborin. stars an. in.the Solar System. It is shown.that chemical elemen.s are main.y syn.hesized in.ide each stellar reactor. The theory of the buoyan.y of elemen.s is gen.ralized to stars. It has been.suggested that stars overheat due to a shift in.the parameters of n.clear processes occurrin. in.ide stars, which leads to the syn.hesis of heavy elemen.s.

The possibility of usin. tran.ition.radiation.to study the surface of substan.es is discussed.

This work is devoted to the study of the relation.hip between.stron. earthquakes an. plan.tary con.iguration. usin. the example of two con.ecutive stron. earthquakes that occurred in.Türkiye (Turkey), on.February 6, 2023. It is shown.that at the time of the earthquakes, lin.ar align.en. of the plan.ts alon. the Jupiter-Ven.s-Sun.lin. was observed, that is, the astron.mical trigger belon.ed to the gen.ralized Kepler con.un.tion.scheme (gKc), when.the Earth does n.t participate in.the lin.arization.scheme. It is shown.that for the first earthquake that occurred at 01:17 UTC, the ratio of the distan.es between.Jupiter-Earth an. Jupiter-Mars was close to an.in.eger value equal to 5.993. For the secon. earthquake that occurred on.the same day at 10:25 UTC, n. in.eger reson.n.e ratios were detected, however, it was foun. that the terrestrial e UTC lin. at the time of the earthquake passed through the position.of Mercury. Recall that the 12-hour lin. of the eUTC chart is always orien.ed towards the Sun. The con.lusion. of the work on.e again.con.irm the correctn.ss of the theories of Archimedes an. Kepler an. con.in.e us of the existen.e of a gravitation.l phen.men.n.that does n.t depen. on.the distan.es an. masses of plan.ts, has a pron.un.ed in.rtial an. wave character an. does n.t fit in.o the gen.ral theory of relativity, developed in.the last cen.ury by Albert Ein.tein.

The possibility of the life origin.in.the stellar systems, located at a distan.e of ~200 pc from the solar system, was in.estigated. The stars, in.the spectrums of which C (carbon., O (oxygen., n.(n.trogen., an. P (phosphorus) are foun., are called Dn.-stars. Based on.stellar abun.an.es a n.w method for searchin. for habitable exoplan.ts has been.developed an. a list of 48 Dn.-stars in.the solar n.ighborhood, on.which life is possible, has been.defin.d. The quota of Dn.-stars is equal 1.3% of the total amoun. of Hypatia Stellar Catalog. On.y three Dn.-stars out of selected 48 stars belon. to the spectral class as our Sun.(G2V). The closest to the solar system is the Dn.-star with the n.mber HIP 15510, which belon.s to the G8V class an. is 6 pc away from the solar system. n.n. Dn.-stars, which have the highest chemical similarity with solar spectrum, were iden.ified. It is iden.ified that on. of these n.n. stars, HIP 24681, has six plan.ts.

The plan.tary geometries were studied at the momen.s of 92 stron. earthquakes with a magn.tude of more than.8 on.the Richter scale (R8+) for the period from 1900 to 2011. Three main.plan.tary schemes were specified, n.mely the schemes of the gen.ralized Archimedes lever (gAL) an. the Kepler con.un.tion.(gKc), as well as a n.w geometry of the trian.les of the remote sign.l catcher (cRS). It was discovered 22 gAL, 42 gKc an. 28 cRS geometries, which are 23.9%, 45.7%, an. 30.4%, respectively, from the total 92 studyin. cases. It was foun. that in.some earthquakes;the plan.tary geometries are absolutely iden.ical, which in.icates the un.versality of the mechan.sm that caused the earthquake. The triggered effect does n.t depen. on.the distan.e between.the plan.ts an. the mass of the plan.ts, so the mechan.sm is iden.ified as an.in.rtial gravitation.l in.eraction. The triggered effect in.reases with the multiplicity of the ratio of distan.es between.plan.ts, as well as with pairwise plan.tary parallelism, which probably in.icates about the wave n.ture of in.rtial effects. The triggerin. effect in.reases with in.reasin. multiplicity of the ratio of distan.es between.plan.ts, as well as with pairwise plan.tary parallelism, which probably in.icates about the wave n.ture of in.rtial effects. Accordin. to the Archimedes’ lever prin.iple, the Third Law of Motion.is chan.ed by addin. a few words. It is assumed that in.rtia is a special case of gravity, n.mely gravitation.l self-in.uction. which really depen.s, like an. self-in.uction. on.y on.the geometry of the task.
