The Energy in the Universe is constant

" I am confused series"

The  Energy in the Universe is Constant.

The energy content in our universe is constant.

It can not be increased or decreased.

The ' Law of conservation of energy ' says,

" Energy can neither be created nor be destroyed."

From where did this energy come ?

It was released during the time of creation ( Big bang ).

Since then, the universe is expanding and energy is spreading.

Energy remains " immutable from eternity to eternity " (Von Helmholtz).

Immutable = not subjected to any change.

One form of energy can be converted into another form.

A fan at home rotates , how ?  By using electrical  power.

Electrical power is obtained from rotating turbines.

Turbines ( wheels ) are rotated by using water falls ( Kinetic energy )

Kinetic energy of falling water is converted into mechanical energy  by turbines.

Mechanical energy is converted into electrical energy by  generators.

Electrical energy is converted into heat energy in electric heaters,

Light energy in  bulbs,  mechanical energy  in  fans, etc,.

Einstein gave the formula for the matter and energy relationship.

Any matter can be converted into energy and energy into matter.

( E = mc square, E = Energy, m = mass,  v = velocity of light which is 3,00,000 Kms/sec )

Matter and energy are one and the same in different form.

Hindu tradition says matter is Shiva and energy is Shakti and they are one and the same.

A motor car runs using petroleum energy. From where did the petrol get energy ?

Plants prepare their food  through photosynthesis by using Solar energy.

Plants store their excess energy within them. Animals eat plants and get energy.

Animals store their excess  energy in the form of fat in their bodies. 

Long time ago, the plants and animals in bulk were buried in the soil by some natural calamities.

The stored energy in them , in course of time converted into petroleum products in the soil.

The ultimate source of petroleum is the solar energy. In the sun nuclear fusion is carried on.

The chain reaction of the nuclear fusion generates enormous heat energy in the sun.

The bulb in a hand torch emits light because of the battery kept in it.

A battery converts Chemical energy into electrical , which is converted into light energy.

No energy can be created by any method, only can be converted from one form to other.

This is the first law of Thermodynamics in Physics.

A wood is burning because of the solar energy stored in it  during  the photosynthesis .

A human body is active because of the food consumed which possessed energy.

Nothing in the universe is static, all are moving, the  universe is full of energy.

The wonder is that this energy cannot be increased or decreased. It is finite.

Why does man with all his innovative techniques , unable to create energy or destroy energy?

Why did God  made it constant ? From where did God obtain this enormous energy?

Where did He store  this energy before  the creation ?

Does He Himself , the Eternal Energy present in the universe ? I am confused.
