Ol argedco luciftias said:The best is Geothermal, but that does not work well everywhere. Geothermal is a closed system, a circuit of water pipes that go deep in the ground. The heat deep under ground turns the water to steam, then the steam comes up and turns a turbine generator to make electricity, then the steam cools down back into water and goes back deep into the ground. It never runs out, it is clean, it does not pollute anything, and it works very well.
A solar panel, just building the solar panel puts out more pollution than it would ever be able to save in its whole lifetime of energy production. So solar panels are actually more harmful than just using some clean form of fossil fuel like Natural Gas. They need to mine all kinds of rare elements and materials to put into the solar panels. And this makes these rare elements get spread all over the land and water, and even into the plants. And some of these materials are deadly to the whole ecosystem.
Nuclear power is extremely clean, efficient, and effective. I think it is one of the best forms of energy. It can efficiently create enough electricity to power very large cities and areas of land. The only problem we need to solve with that is finding a clean safe way to dispose of the used up nuclear materials.
I spent most of my childhood watching Science Channel and Discovery Channel. And I always remember basically everything that I ever learn. Also paid very close attention in all my history and science classes. If I see anything related to any other thing that I heard before, it makes me remember about that other thing.NinRick said:I noticed that you are pretty knowledgeable regarding science and connecting science with spirituality

Nuclear energy sounds cool, but at the current state of human conscious development would cause a lot of problems for the Earth and for humans. Solar energy and other forms which are renewable like Wind and Geothermal energy should become the universal and central forms of energy production. If societies on Earth become more cohesive from any positive social result of the ongoing world events, people are going to end up building more of these energy sources anyway, as they are generally cheaper than a massive power plant that uses dwindling or dangerous resources, and they also are more will be more in the collective interest for long-term survival as well.
I second Master's quote of "The Sun sacrifices itself with fission and fusion and shines for us". It's very poignant and a good way to put it. We don't have to sacrifice ourselves to radiation when we have our Sun and our life giver doing it for us. The Sun is eternal in its processes of Fusion and fission, the Earth and humans are not so much.
It is, in fact, the form of energy normally used by autotrophic organisms, i.e. those that perform photosynthesis, commonly referred to as "plants" (from which fossil fuels also originate); the other living organisms exploit, instead, the chemical energy obtained from plants or other organisms that in turn feed on plants and therefore ultimately also exploit solar energy, albeit indirectly.
Almost all other energy sources available to humans such as fossil fuels, hydropower, wind energy, wave energy, biomass energy, with the only exceptions of nuclear energy, geothermal energy and tidal energy, derive more or less directly from this energy. It can be used directly for energy purposes to produce heat or electricity with various types of plant. On Earth, the value of this energy (local or global, daily, monthly or annual) can be calculated as the product between the average insolation, heliophane in the time interval considered and the incident area considered. From the energy point of view, it is an alternative energy to traditional fossil fuels, renewable and, regardless of the capture and conversion technologies used, clean (green energy) and one of the energies supporting the hypothetical green economy in modern society. It can be properly exploited through different technologies and for different purposes, although in the technological versions that do not provide for integrated storage, the exploitation suffers from variability and intermittence of production or not full programmability (dispatching) due to day-night cycles and cloud cover. On average, the Sun radiates at the threshold of the Earth's atmosphere 1367 W/m², known as the solar constant and distributed according to the solar spectrum. Taking into account that the Earth is approximately at a sphere with an average radius of 6371 km, it intercepts a section of more than 127.5 million km² of the solar emission, whose product for the solar constant corresponds to an intercepted power of 174300 TW. Depending on the season, due to the eccentricity of the Earth's orbit, this intercepted power varies between 168500 TW and 180000 TW. Of this value, about 30% is reflected back or intercepted by the atmosphere and a part ends up on the oceans; but the remaining power potentially captured on land remains enormous, of the order of several tens of thousands TW of power (to make a comparison, keep in mind that the average power of a large power plant is around 1 GW, where one TW is worth a thousand of these plants). The average solar radiation or insolation is, at European latitudes, as an annual average, between 3 kWh per day in the north and 5 kWh per day in the south. If we imagine an equivalent source as a total quantity, but at constant power, dividing the values by the number of hours per day, we obtain between 125 W/m² and 210 W/m². Obviously this measure only serves for a convenient calculation of the potential of a surface area of a territory, but the real source is strongly intermittent with cyclic diurnal peaks that vary seasonally. The amount of solar energy that arrives on the earth's soil is therefore enormous, about ten thousand times more than all the energy used by mankind as a whole, but little concentrated, in the sense that it is necessary to collect energy from very large areas in order to have significant quantities, and rather difficult to convert it into energy that can be easily exploited with acceptable efficiencies. For its exploitation, generally high cost technological products are needed, which currently make solar energy considerably more expensive than other methods of energy production. The development of technologies that can make the use of solar energy cheap is a very active area of research but one that, for the moment, has not yet had revolutionary results. At present, most studies focus on new generations of photovoltaic cells with a higher efficiency than the current ones or on photovoltaic cells with an efficiency similar to that of the current cells but much cheaper.
More ambitious studies aim at the construction of orbiting solar power plants. These power plants should collect the sun's rays directly into space and transmit the power absorbed on Earth by means of microwaves or laser beams. Prototypes of photovoltaic cogeneration systems in which the simultaneous production of electrical and thermal energy is carried out are being tested.
Almost all the characteristics of a star, including brightness, size, evolution, life cycle duration and ultimate destiny, are determined by its mass at the time of formation. Mass, radius, acceleration of gravity at the surface and period of rotation can be measured on the basis of stellar models; mass can also be calculated directly in a binary system using Kepler's laws combined with Newtonian mechanics or through the gravitational lens effect. All these parameters, associated, can allow to calculate the age of the star.
Most stars are between 1 and 10 billion years old. The length of a star's life cycle depends on the mass it has at the time of its formation: the more massive a star is, the shorter its life cycle is. In fact, the pressure and temperature that characterize the nucleus of a massive star are much higher than those present in less massive stars; as a consequence, hydrogen is melted more "efficiently" through the CNO cycle (instead of the proton-proton chain), which produces a higher amount of energy while reactions take place at a faster pace. The most massive stars have a life close to a million years, while the less massive ones (such as orange and red dwarfs) burn their nuclear fuel very slowly and live for tens or hundreds of billions of years.
The Universe is commonly defined as the complex that encloses all space and what it contains, i.e. matter and energy, planets, stars, galaxies and the content of intergalactic space. Scientific observation of the Universe, whose observable part has a diameter of about 92 billion light years, suggests that the Universe has been governed by the same laws and physical constants for most of its history and in all its observable extension, and allows inferences about its early stages. The Big Bang theory is the most credited cosmological model describing the birth of the Universe; it is estimated that the Big Bang occurred, seen from our local time frame, about 13.798 ± 0.037 billion years ago. The maximum theoretically observable distance is contained within the observable universe. Observations by supernovas have shown that the Universe, at least in the region containing the observable universe, seems to expand at an increasing rate, and a series of models have arisen to predict its final fate. Physicists are uncertain about what preceded the Big Bang; many refuse to speculate, doubting that information about the original state can ever be found. Some propose models of a cyclic universe, others describe an initial state without boundaries, from which space-time emerged and expanded at the time of the Big Bang. Some theoretical speculations on the multiverse of cosmologists and physicists speculate that our universe is only one of many that can exist.

Studying and exploring the universe is the greatest thing you can do forever.
A galaxy is a large set of stars, systems, clusters and star associations, gases and dust (which form the interstellar medium), bound by the reciprocal force of gravity. The name derives from the Greek γαλαξίας (galaxìas), which means "of milk, milky"; it is a clear allusion to the Milky Way, the Galaxy par excellence, of which the solar system is part. Galaxies are very large objects; they range from the smallest dwarf galaxies, containing a few hundred million stars, to giant galaxies, which also have a thousand billion stars, orbiting around a common centre of mass. Galaxies have been categorised according to their apparent shape, i.e. on the basis of their visual morphology. A very widespread typology is the elliptical one, which, as we can well argue from the name, has an ellipse profile. Spiral galaxies, on the other hand, have a discoidal shape with spiral-like structures departing from the nucleus. Galaxies with irregular or unusual shapes are called peculiar galaxies; their strange shape is usually the result of the effects of tidal interactions with nearby galaxies. If such interactions are particularly intense, due to the great closeness between the galactic structures, the fusion of the two galaxies may take place, resulting in the formation of an irregular galaxy. The collision between two galaxies often gives rise to intense stellar formation phenomena (Starburst jargon). There are probably more than 100 billion galaxies in the observable universe; according to new research, however, the estimated number of galaxies in the universe would be at least ten times higher and more than 90% of the galaxies in the observable universe would be undetectable with the telescopes we have today, which are still too little powerful. Most of them have a diameter between 1000 and 100,000 parsecs and are usually separated by distances in the order of millions of parsecs (megaparsec, Mpc). The intergalactic space is partially filled by a small gas, whose density is less than one atom per cubic meter. In most cases the galaxies are arranged in the Universe according to precise associative hierarchies, from the smallest associations, formed by some galaxies, to clusters, which can also be formed by thousands of galaxies. These structures, in turn, associate in the most imposing galactic superclusters. These large structures are usually arranged within huge currents (such as the so-called Great Wall) and filaments, which surround immense voids in the Universe. Although it is not yet completely clear, dark matter seems to constitute about 90% of the mass of most spiral galaxies, while for elliptical galaxies this percentage is believed to be lower, varying between 0 and about 50%. The data coming from the observations lead us to think that at the centre of many galaxies, although not all of them, there are supermassive black holes; the presence of these singular objects would explain the activity of the nucleus of the so-called active galaxies. However, their presence does not necessarily imply that the host galaxy is active, since the Milky Way most likely also hides a massive black hole called Sagittarius A* in its core.
Deep space observations show that galaxies are often found in relatively close associations with other galaxies. Solitary galaxies that have not had significant interactions with other galaxies of similar mass in the last billion years are very rare: only 5% of the observed galaxies show conditions of true isolation. However, these isolated formations may have had interactions and possibly merged with other galaxies in the past, and may also have smaller satellite galaxies. Isolated galaxies, sometimes also called field galaxies, may produce stars at a higher than normal rate because their gas is not ripped away by interactions with other nearby galaxies. On a larger scale, the Universe, in accordance with Hubble's law, is constantly expanding, resulting from the increasing distance between individual galaxies. Galactic associations can overcome this tendency to expansion only on a local scale, through their mutual gravitational attraction. Such associations were formed in the first stages of the Universe, when groups of dark matter attracted together their respective galaxies; later on the closest groups merged, giving rise to larger clusters. This process of fusion between groups of galaxies heated the intergalactic gas inside the cluster to high temperatures, which in some cases reached 30-100 million K. This temperature value is not to be considered in classical terms, but it is a value obtained taking into account the kinetic energy of the particles, which are extremely rarefied. About 70-80% of the mass of a cluster is formed by dark matter, of which 10-30% goes to constitute this gas at high temperature; the remaining 20-30% of the total forms the galaxies. Most of the galaxies of the Universe are gravitationally bound in hierarchical structures of clusters, which follow the shape of a fractal, containing most of the baryonic mass of the Universe. The most common type is the galactic association, consisting of a few members. In order for the association to remain stable, each member galaxy must have a sufficiently low velocity to avoid its own receding (see Virial Theorem); however, if the kinetic energy is too low, the group could evolve into a group with fewer galaxies, since some of them will tend to merge with each other. The larger structures, which contain several thousand galaxies concentrated in an area of a few megaparsec (1Mpc = one million parsecs), are called clusters. These structures are often dominated by a single giant elliptical galaxy, known as the brightest cluster galaxy, which over time disintegrates its satellite galaxies due to its great tidal force, acquiring mass. Clusters and associations, often together with some individual galaxies, are in turn grouped into super clusters of galaxies, which contain tens of thousands of galaxies. At the level of the superclusters, the galaxies are arranged within vast surfaces and filaments, surrounded by vast empty areas. Beyond this scale, the Universe appears to be isotropic and homogeneous. The Milky Way is a member of an association called the Local Group, a relatively small group of galaxies with a diameter of about one megaparsec. The Milky Way and the Andromeda Galaxy are the two brightest galaxies in the group, and they regulate their gravitational dynamics; the other members of the group are dwarf galaxies, often satellites of the two main ones. The Local Group is in turn part of a spheroid-shaped structure within the Virgin's Supercluster, a very large structure of groups of galaxies surrounding the Virgin's Cluster.

Very nice man!
I'm most interested in electro-magnetic forces and actions. And it really is amazing how perfectly all those equations match up with the spiritual knowledge that we have here. But all of it is really the same thing, the same fundamental types of forces that everything is made from. Like how a swastika spinning counter-clockwise at the speed of light, the magnetic field is in a circle the same direction it is spinning, this creates a current of energy going directly into you. This comes from the equations between electric current, magnetic fields, and movement. But it is also true spiritually. When you see this symbol in your mind focused on your 3rd eye, and you imagine it spinning in that direction, you really do feel the current going into your 3rd eye. This is one of the most obvious examples that I can think of, that nobody can try to deny. These shapes are in the deepest layers of physics, and they are always true in every situation.
i remember hoodedcobra saying nuclear energy is the most used energy and that we can't go in the"green peace"way,however,i agree more with mageson's solar panels,since nuclear energy is NOT clean,it's the most TOXIC and dangerous one,plus,there are homemade solar cells made out of simple,eco-friendly materials,just search on the internet for themOl argedco luciftias said:The best is Geothermal, but that does not work well everywhere.
