The Planets Of The Material Universe

          When saying "cosmic manifestation" they speak of separate worlds, the spiritual & the material. The spiritual planetary systems are eternal, beyond the limits of the material universes, & belong to a "super dimensional" or "anti-material" dimension. These are beyond the limitations of material time & space & therefore beyond our vision, or powers of perception. In these planetary systems there is no occurrence of creation or dissolution, & these planets are countless, indestructible, & eternally existing. There's descriptions of these spiritual planets in the vedic literatures, but this editorial concentrates on those within the    material universe.
The cosmology & cosmography of the ancient Vedas is awe inspiring to say the least. The more "modern" of the Vedic texts are known to originate from about 3000 B.C., thus being the oldest scientific & religious doctrines known to man. The descriptions of our solar process & what modern astronomy has discovered of the visible universe corresponds with the ancient Vedic knowledge, proving that man has had advanced knowledge of astronomy for thousands of years before our modern civilization began. This editorial describes the Vedic version of planetary systems from the topmost, eternal planets down through the temporary planetary systems within innumerable universes of this material world.
Goloka-dhama is the topmost planet & residence of the Supreme Godhead Sri Sri Radha-Krishna. Below this is Hari-dhama where the spiritual planets of the Vaikunthalokas are situated. Below the Vaikuntha planets is "Mahesh-dhama" (also called Sadasivaloka, or the abode of Lord Siva). This is the realm dividing the spiritual from the material universes. Below Mahesh-dhama is Devi-dhama, the realm of the material universe. It is said that the systems of yoga offer different destinations. Bhakti yoga directs toward entering Hari-dhama or Goloka-dhama. Jnana yoga directs the aspirant toward entrance to Mahesh dhama, & karma yoga directs to stay in Devi-dhama, experiencing repeated birth & death in the material worlds.
The material planetary systems are created at some point in time & will be destroyed at another. They are bound by the influences of time & space. Both of these energies (spiritual & material) are of the same divine source called "brahmajyoti", the spiritual light. About 1/4th of this brahmajyoti is covered by the "mahat-tattva", the material energy, where are found innumerable material universes. The 3/4th portion is the eternal spiritual sky. In the spiritual world are realms of existence, "Goloka-dhama" & "Hari-dhama". The material world has realm called "Devi-dhama".

5 Benefits of using The Sun's energy With Solar Panels

Neat Resources


 of the prime benefits of moving away from traditional forms of energy and on to solar panels is fact that fossil fuels are nonrenewable. What this means is, basically, when they are gone, they are gone. They are not close to walking out yet, but when the world's population is in exponential growth, the fight over oil is causing war and death around the planet, and there is an wonderful amount of proof pointing to artifical global warming, it is simple to see why making the switch is in everyone's best interests.


If you are a homeowner, you have probably thought at some point or another about putting up solar panels and getting away from the oppressive bills of the electrical company. While not all options regarding the usage of the sun's energy will free you entirely from the grid, it can definitely reduce your reliance on that central power. But that is of lots of benefits of going this route. At point in the 70s, it appeared definite that they were headed in such a direction as a country. Because the know-how wasn't there yet, however, it was pushed to the backburner. Today, it is back with a vengeance and there's several reasons you ought to think about taking part.


While it may benefit your relatives to move to solar panels, it can actually be done on a much larger scale. Definite cities and communities are already finding this out, as photovoltaic power plants provide energy to hundreds of houses in the region. Will this type of solution work all over the place? Perhaps not, but it is intriguing to think about the possibilities of moving off the grid on a widespread scale.


The Micro and the Macro


Non-Polluting


For somebody concerned about the environment, solar panels are a no-brainer. Every tiny bit of oil consumption leads to a point of pollution. While nuclear power produces far less, it's its own disadvantages, when it comes to public relations. Using the sun's energy does not increase your carbon footprint and does not contribute to the greenhouse effect.


Low Maintenance


Somebody who desires a power process that won't need to be repaired every six months ought to definitely look in to solar panels, as they are low maintenance and have a reputation for lasting0 or thirty years after being installed.

The Earth's Structure

Our continents & the ocean floor are on the outer layer of the earth, the earth's crust. Compared to the whole radius of the earth (the median earth's radius measures 6.370 kilometres), the earth's crust is narrow. Underneath the oceans, the thickness of the earth's crust measures between 8 to 15 kilometres. Underneath the continents it reaches 30 to 100 kilometres in to the inside. Underneath Central Valley in New york, for example, the earth's crust is only twenty kilometres thick, while underneath the Himalayas it reaches the depth of 90 kilometres. In the upper crust, the seismic waves travel at different speeds. This indicates the existence of a great variety of rocks.

We know today, that the earth is surrounded by earth's crust consisting of a comparatively light rock. Underneath is the earth's mantle. On the outside, the mantle is formed by a solid rock, which turns liquid as it descends closer to the earth's core. The core consists of parts, the outer & the inner core, & its material is mostly iron. The temperature of the inner core is probably similar to the temperature that exists on the surface of the sun.


In comparison with the ocean crust, the structure of the continental crust is much more varied & stronger. It contains rocks that are up to three,8 million years elderly. The effects of wind erosion, deformation, rising & lowering created lots of diverse layers. The surface is often formed by sediments & volcanic rocks, which have a low density. Underneath they discover a folded metamorphic sedimentary layer, linked partially to a granitic layer. The lower portion of the crust contains crystallised & metamorphic rock layers extending all the way to the earth's mantle.


Between the crust & the upper mantle is a prominent boundary, named after its discoverer the Mohorovi discontinuity, or Moho for short. When analysing seismological knowledge, Mohorovi discovered that in that particular place the travelling speed of seismic waves noticeably changes, which also means that there is a different material in the earth's core.


In contrast, the structure of the ocean crust is comparatively simple. It consists of smaller number of layers. First, there is a firm sediment measuring from a few hundred metres to up to kilometres. Underneath this sediment they discover a layer consisting of hard rock - chiefly basalt & a minor admixture of sedimentary rock. This layer measures on the average one,5 kilometre. It is followed by a five-kilometre thick layer of basalt or gabbro, which is penetrated by giant cones of magma streaming up from the earth's mantle. The temperature in the earth's interior rises in direct relation to the depth. Beginning from the earth surface, they estimate that the temperature rises 30 degrees Celsius with each kilometre in to the earth's interior.

The earth's crust & the upper part of the earth's mantle, up to the Gutenberg Zone, form the lithosphere. The asthenosphere, which is less firm, lies underneath. The asthenosphere & the lithosphere are interactive. When material from the asthenosphere rises in the Mid-Oceanic Ridge, it becomes lithosphere. In the subductive zones (when plate slides underneath the neighbouring plate - proof-reader's note), the opposite occurs. In the midst of the earth's mantle the density increases & so does the speed of the seismic waves (P-waves). The lower part of the mantle consists chiefly of silicon. Having a density of 9,4 gram per square centimetre it is connected to the earth's core. This region is called Wiechert-Gutenberg discontinuity.


The earth's mantle, situated underneath the earth's crust, represents about 82 percent of the earth's volume & 67 percent of its total mass. The seismic waves & volcanic debris provide knowledge concerning its composition. Based on its physical properties, they can divide the comparatively icy earth's mantle in to upper & lower layers. Analogous to what is happening in the earth's crust, here, , they register changes in the seismic waves. These changes occur in a specific area, in the depth of 100 to 200 kilometres. This region is called the Gutenberg Zone. It is feasible, that the reason for the deviation of these waves is the convective flow in the inside of the earth.


They know comparatively small about the earth's core. Seismic waves penetrate the core only partially or are deflected by it. While its inner part, with a diameter of 2400 kilometres, consists of solid iron & nickel, the outer core, which is 2300 kilometres thick, is molten iron & nickel. According to calculations, the density of the earth's core is times higher than the density of the earth's crust. Iron is the only substance they know that has this density, & it is therefore over likely that it forms most of the earth's core.

Dwarf Planets In The Solar System

Based on this classification, Pluto was assigned as a dwarf planet and no longer regarded as a planet. While dwarf planets do orbit around the sun, they don't have sufficient force to overcome forces and form a round shape. Also, they are unable to clear the path of their orbit of objects that could be satellites of other planets. Today, there's five dwarf planets that they know of. They are Eris, Pluto, Haumea, Makemake and Ceres. Out of all the known dwarf planets, the largest is Eris, while the smallest is Ceres.

While they were in school, they studied that our Solar Process is made up of nine planets, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune and Pluto. However, they may must unlearn this knowledge. In the year 2006, the International Astronomical Union started using another process of classifying stellar objects. This classification believed that three types of stellar objects were present in the Solar Process, namely planets, dwarf planets and bodies of Solar Process.


The name of the dwarf planet was taken from Greek mythology. Eris was the goddess of warfare and conflict. They was responsible for bringing hatred, anger and jealousy amongst men which caused them to fight another. The name was carefully chosen as the discovery of this dwarf planet was plagued with controversies. The astronomy community was happy with the way Eris was classified. Hence, it got an appropriate name.


Eris was first spotted in the year 2003, but it was confirmed only in the year 2005, in January by an astronomer from Michigan Institute of Know-how named Michael Brown. It is the most distant stellar object to be discovered orbiting the Sun.


 being discovered, Eris was first named 2003 UB313. Then it earned the nickname Xena, and at last in September 2006, the dwarf planet was officially called Eris by the International Astronomical Union.


Scientists think that Eris' outer layer is made up of frozen methane that has managed to seep its way in to the insides. As not much radiation from the Sun reaches the dwarf planet, the surface of Eris is yellowish in color. Till now, scientists have been able to discover moon revolving around Eris and they have named the moon Dysnomia, who in Greek mythology was Eris' daughter. Dysnomia takes around two weeks to orbit around Eris.


Eris has a slightly bigger diameter compared to Pluto at two,400 kilometers. It around 97 AU from the Sun and takes around 577 years to complete an orbit around the Sun. The temperature on Eris varies from -217 degrees Celsius to -243 degrees Celsius.


In order to see Eris, you need an powerful telescope. You won't be able to see this planet with a pair of binoculars or bare eyes.
