Every year on 22 April, we have celebrated Earth Day and the beautiful planet we call home. Earth Day, es.ablis.ed in 1970, has.been us.d to highlight our planet’s.environmental challenges.and rais. awarenes. of the importance of protecting our world for future generations.[1]. To provide the protection of our planet, we s.ould explain Earth’s.environmental challenges.to the bes. of our k.owledge in frames.of contemporary Geophys.cs. This.paper gives.a s.ort overview of the developed Hypers.here World-Univers. Model (WUM) and pay particular attention to the principal role of Dark.Matter (DM) in the Earth’s.life. In this.manus.ript, we dis.us. different as.ects.of the Earth: a condition of Young Earth before the Beginning of life on It;Internal s.ructure;“The 660-k. Boundary” that we named Geomagma;Random Variations.of Earth’s.Rotational s.eed on a daily bas.s.Origin of Moon;Expanding Earth;Internal Heating;Faint Young s.n paradox;Geocorona and Planetary Coronas.High-Energy Atmos.heric Phys.cs. WUM propos.d principally different ways.to s.lve the problems.of Internal Heating, Origin of the Moon, and Faint Young s.n paradox bas.d on DM core of the Earth. The Model revealed the fact that the s.n Activity caus.s.the Geomagma Activity and, as.a cons.quence, Random Variations.of Earth’s.Rotational s.eed by the varying s.n’s.magnetic field.

This.s.udy predicts.the characteris.ics.of a compres.ible polytropic air s.ring model. A s.cond-order nonlinear autonomous.air s.ring model is.pres.nted. The propos.d model is.bas.d on the as.umption that polytropic proces.es.occur. Is.thermal and is.ntropic compres.ion and expans.on of the air within the s.ring chambers.are the two s.enarios.that are tak.n into cons.deration. In thes. s.tuations. the air ins.de the s.ring chambers.compres.es.and expands. res.lting in nonlinear s.ring res.oring forces. The MATLAB/s.mulink.s.ftware environment is.us.d to build a numerical s.mulation model for the dynamic behavior of the air s.ring. To quantify the values.of the s.iffnes.es.of the propos.d models. a numerical s.lution is.run over time for various.values.of the des.gn parameters. The is.ntropic proces. cas. has.a higher dynamic air s.ring s.iffnes. than the is.thermal proces. cas., according to the res.lts. The s.ze of the air s.ring chamber and the area of the air s.ring pis.on influence the air s.ring s.iffnes. in both s.tuations. It is.demons.rated that the s.iffnes. of the air s.ring increas.s.linearly with increas.ng pis.on area and decreas.s.nonlinearly with increas.ng air chamber length. As.long as.the ratio of the vibration’s.amplitude to the air s.ring’s.chamber length is.s.all, there is.good agreement in both s.enarios.between the linearized model and the full nonlinear model. This.implies.that linear modeling is.a reas.nable approximation of the complete nonlinear model in this.particular s.enario.

Great experimental res.lts.and obs.rvations.achieved by As.ronomy in the las. decades.revealed new unexplainable phenomena. As.ronomers.have conclus.ve new evidence that a recently dis.overed “dark.galaxy” is. in fact, an object the s.ze of a galaxy, made entirely of dark.matter. They found that the s.eed of the Earth’s.rotation varies.randomly each day. 115 years.ago, the Tungus.0} Event was.obs.rved, and as.ronomers.s.ill do not have an explanation of It. Main res.lts.of the pres.nt article are: 1) Dark.galaxies.explained by the s.inning of their Dark.Matter Cores.with the s.rface s.eed at equator les. than the es.ape velocity. Their Rotational Fis.ion is.not happening. Extras.lar s.s.ems.do not emerge;2) 21-cm Emis.ion explained by the s.lf-annihilation of Dark.Matter particles.XIONs.(5.3 μeV);3) s.n-Earth-Moon Interaction explained by the influence of the s.n’s.and the Moon’s.magnetic field on the electrical currents.of the charged Geomagma (the 660-k. layer), and, as.a res.lt, the Earth’s.daylength varies.4) Tungus.0} Event explained by a huge atmos.heric explos.on of the s.perbolide, which was.a s.able Dark.Matter Bubble before entering the Earth’s.atmos.here.
