Conservation of Energy?

The law of conservation states that the total amount of energy in an isolated system remains constant over time (is said to be conserved over time). A consequence of this law is that energy can neither be created nor destroyed, it can only be transformed from one state to another.

Let's study this law profoundly. It stated that the energy cannot be created. However, the flaw is that the gravitational energy can be form constantly without any input of the external sources. An object will exert gravitational force depending on its size.The bigger the mass,the larger the gravitational force it exert. The gravitational force cannot be destroyed but it can be created free once it has mass. Our planet earth has enormous mass and it generate free gravitational force at its own and provide us the potential energy needed to run the hydroelectric station, thus provide us electricity. Gravitational energy does not need any fuel to work it out. It is fully automated in accordance to the mass and it is a green energy.
In future, it is possible for mankind to gather all the space dust and rocks to form a planet. The larger the crump of rocks, the greater the gravitational pull.

My conclusion is energy CAN be created but cannot be destroyed.

I want to add somemore. Eventhough the fuel for the burning sun or star is hydrogen and helium, but if those furnace without the ignitor, it won't burn at all. The ignitor is gravity itself. Intense gravity of the gigantic sun and stars compress its material and temperature risen to a point that it start the fusion process of the hydrogen atom under intense heat and pressure. So where does the gravity energy originate from? It is from the mass of the body, it give you free energy sources in every objects. You can harvest gravitational energy through potential energy in hydroelectric power and heat energy in geothermal power. In conclusion, the mass itself CREATE gravitational energy out of nothing input into it. So our life start from gravity that burn our sun and give us energy through photosyntesis in plants. If gravity is non-existense, then we will never be here today.

And if the planet earth's mass is equal to 0.7 mass of the sun or more, we will never exist today in planet earth as this planet earth is engulf in flames.

You are incorrect because all the matter that made up the Earth had gravity before the Earth formed. The gravitational force of the Earth is simply the gravitational force of all it's matter combined. Gravity can be an energy source, such as with hydroelectric power, but only because the Sun lifted the water first before it filled up a reservoir.

Matter was created from energy in the early universe. Observations indicate that the positive energy of matter is exactly balanced by negative gravitational potential energy. Thus, the total energy of the universe is zero and no energy (or very little--just the amount allowed by quantum mechanics) was required to produce the universe.

Wrong!! The gravitational force is independent of any outside sources and it does not need any input energy from 'dark matter' or other energy sources. gravitational forces of the matter is dependant on mass itself and the energy it exert will never diminish forever given a constant mass. For example you will never see earth gravitational force diminish if no rocks is taken out to the space. But you will see earth's gravitational force is getting stronger everytime a space rocks and dust land on earth, although it is left unnoticed due to small fraction of those dust as compare to earth mass.

It is dependent on matter, which took energy to form. The proof of this is that it releases huge amounts of energy when split (fission). It's existence does not violate the law of conservation of energy.

 

lets do a little bit of experimenting on rock sample. you mentioned fission process of a rock that give out its energy. but if the gravitational energy of that particular rock consumed its hidden energy, then the mass of the rock will be diminished in accordance to E=MC^2. But there is no conclusion for this. So gravitational force of an object does not consume its own hidden energy at all. And it will give out perpetual constant energy sources as gravity.

 

How do you extract energy from gravity? You could lift a heavy weight up high and use it's falling to generate energy, but it's only the energy you put into it by lifting.

 

:itold: it is the energy that pull the moon round the earth, earth round the sun, sun round the Milky Way. So do you know how strong the energy is? 100000000000000000 trillion times more powerful than your Ferrari car.

As i said earlier, intense gravity produce pressure and heat, so we have heat source underground. As to the potential energy, lets our mighty sun do his job.

 

I really think albert needs to learn the basics of what a force is and what a potential is. Newtonian gravity and general relativity both have energy conservation, though in GR you're allowed to turn energy into mass and vice versa.

 

So you are talking about wave energy, which isn't gravity exactly, it's due to the changing force of gravity as the moon revolves around the Earth, an energy imparted to the system in it's very early stages. If the moon were static in position relative to the Earth, that wouldn't be possible.

 

So do you expect to see a matter to shred mass to form gravitational energy? The answer is NO. So you cannot convert mass to gravitational energy.

Perhaps not directly but certainly things like the Sun or any other star due over time.

Stars turn mass into energy via fusion, the Sun manages to 'burn' 4 million tons every single second. This energy is mostly in the form of thermal energy, the products of the fusion are moving very quickly. If you heat a gas it expands and stars are gravitationally bound clumps of gas so by expanding they actually increase their gravitational energy. This is a non-trivial amount of energy, if the Sun stopped burning fuel tomorrow it'd be able to shine for a few million years or so simply by shrinking and turning its gravitational potential energy into heat (it was the method originally put forth to explain the Sun's heat output, back around 1880 by Kelvin). When a star stops burning Hydrogen and hots onto Helium it often throws off a lot of its outer layers and the energy to do this comes from its heat, which comes from its mass.

So really you only needed to look up at that giant brilliant light in the sky to see a counter example to your claim.

Your claim is that mass can't be turned into gravitational energy. But obviously mass can be turned into heat, which can be turned into whatever we like (its how we generate electricity, heat boils water, makes the steam expand, the movement spins a turbine, which makes electricity via electromagnetism). Clearly many forms of energy can be turned into kinetic energy which can move an object upwards. The Shuttle uses chemical energy. An elevator (or for those of us who are British, a lift) uses electrical energy. Hell, the Sun's heat evaporates water, which rises, forms clouds and then falls as rain. All forms of energy are convertible into one another, the issue is how easy it is or how efficient it is.

 

Back to the basic, I am not talking about gigantic star that loss weight because of radiation emission. But what i emphasize in here is a matter that is under controlled environment. Such as a piece of rock on my experiment desk with neither reactive chemical pour onto it nor heat it up using burner. That piece of rock do exert gravitational force, do you think it will shred its mass as time pass by?

 

You're making a common mistake, thinking it takes energy for a magnet to stick to a fridge door or a table to hold up a book. It doesn't. Energy changes only happen when an object moves against or with a force by some distance. Its the usual high school formula of 'Work done = force * distance moved'. If an object doesn't move then work done is zero.

The reason people usually think it might cost energy is that you get tired holding a book at arms length or trying to push a heavy object which won't move. This is due to your muscles working in a particular way, not some underlying physical phenomenon.

 

Wrong!! Permanent magnets are made from "hard" ferromagnetic materials which are subjected to special processing in a powerful magnetic field during manufacture, to align their internal microcrystalline structure, making them very hard to demagnetize.

So you haven't answer my question? Does my experimental rocks loss weight to gain gravitational energy?

What did I say which was wrong? Your reply doesn't retort anything I said. The manufacture of magnets involves processes which make it a stronger magnet, by aligning the microscopic magnetic properties to make a stronger macroscopic field effect. This does cost energy to do because you have to work against the magnetic field, just as pulling two attrating magnets apart costs energy.

It costs some form of energy to gain gravitational energy. Where that energy comes from depends on the mechanism which is causing the object to increase its gravitational energy. If you throw a rock upwards the energy comes from your muscles. If you detonate an explosive some of the debris is propelled upwards, its gravitational energy is gained from the chemical energy in the explosive.

15 year olds know that work done is force times distance. You seemed to have slept through that class.

 

there is NO other machanism to increase or decrease its gravitational energy of a matter. It is all dependant on its mass. The larger the mass, the stronger the gravitational energy.

And.... How does gravity formed from mass? I bet even the current brightest scientist don't know the answer yet... God's Rules....

And....Hopefully.... If someone is able to crack this secret in the future on how the gravity is formed from mass, then you will be able to find the solution to anti-gravity matter. This is how the advance aliens do it on their craft. The future of levitation using anti-gravity matter is within reach now.

 

Gravitational energy, in terms of Newtonian mechanics, is the energy an object has due to its position in a gravitational field. In the absence of a restorative force the object will accelerate, turning the gravitational potential energy into kinetic energy. In such a process the gravitational energy of the system is decreasing.

You seem to have a fundamental lack of grasp of how energy and force is related. And you have nothing to justify your assertion other than what you guess happens in nature. Actual physicists do experiments.

Doesn't mean you can just make up nonsense and consider it as valid as any other hypothesis. Besides, things like string theory and loop quantum gravity do have explanations and string theory even provides the Einstein field equations, which govern the relationship between gravitational fields and the material within them. Matter is formed from strings and membranes which oscillate and ripple. When a ripple is strong enough it'll pinch off the string or membrane to form a closed string loop which just so happens to be the string theory model of the graviton, the force carrying particle for gravity. The presence of the strings and/or membranes provides a source of gravitons and when you put in lots of energy to the string or membrane then they throw off more gravitons.

I suggest you actually look up what physicists say and do, rather than being dishonest and just making stuff up on a topic you know nothing about. You should have learnt that in this thread already, given you've been making bold assertions about things in nature when you know nothing of any experimental observations or related models. You're aware you're making it, why bother?

Another assertion without justification.

And you know this how? Did they abduct you and explain their propulsion to you?

You know you don't know what physicists say or what experiments they do so why do you make up stuff? What do you get from lying?

 

we do have diamagnetic levitation, vacuums, and the coriolis effect at our current disposal... you add them up and you get a floating spinning magnet. and last i herd magnets spin for 15 minutes or so in their current density level (not in vacuum).
