Law of conservation of energy

[tittat]

The law of conservation of energy states that energy may neither be created nor be destroyed. Therefore the sum of all the energies in the system is a constant.


If this is the case how this present energy is created?
May be God.
Then how the God is created?
This question has no specific answer. And this is not what we are going to discuss it here.

According to law of conservation, energy is not created nor be destroyed.But it can be transformed from one form to another with out loss or gain.

Then how this universe is moving or how this energy is flowing?
The energy in this universe is flowing from higher potential area to lower potential area. Examples: the energy is flowing from sun to earth,the river is flowing....etc...
i.e the energy is doing some work and the potential of the energy is degrading... and degrading.

How long this energy in this universe will flow?
The energy in this universe will flow until the potential of this whole universe become same.i.e the energy in this universe is continuously flowing from higher potential to lower potential and one day,there exist no potential difference.Then there will be no life,no sun ,no earth,no particles,no molecules,no atoms........This will be true if the first law(law of conservation of energy)(law of conservation of energy) is true.



But i dont think so.I think the first law itself is false.
And i will say energy can be created and can be destroyed.And if it isn't,how this world is created by GOD?

What you think about my views?


Well thought discussions are welcome.....

I think the law of conservation of mass is true.
But you might also say how do we get bigger as we get older? We must be creating something.
But that something is things from the food we eat and drink.
So in a sense, it makes sense.
Now how the first creatures were created is uncertain. No one knows.
(The main idea of this law is that when a substance changes forms, no mass is created or destroyed)

I know we are not discussing it but still, In defense on God:
Ive said it before, and ill say it again:

Science dosnt tell you that god dosnt exist, and even today there are so many things that no scientist can explain. Infact the more you study physics, the lesser knowledgeble you feel.
For example you may laugh at the concept of "heaven". You may argue how can there be such a place where you dont age, or feel hungry? You may be surprised to learn that it is very well possible, within the rules of physics!
We all are familiar with the Big Bang. It is that event which created, not only the universe but also space and time itself.
Time simply didnt "exist" before the big bang nor did space.
Now imagine you somehow manage to "move out" of our universe. For you then, the coordinates of space-time we use wouldnt apply. Time would stop for you! You wouldnt age, feel hungry, thirsty, [no time no metabolism!] in short you would have reached heaven!

potential of the energy is degrading

Energy dosnt degrade, its dissipated as heat and potential energy.

Energy dosnt have to "flow", its not water. It is interconverted by interaction of matter or other forms of energy, or it may be redistributed. For example if you lift a book, you store potential energy in it. No energy flowed, did it?

Heat, a form of energy flows.
The concept you are refering to is explained by Thermodynamics. The first law of thermodynamics is the law you have stated, the second defines the concept of "entropy" which explains why heat will never stop flowing in the universe. Look in here: http://en.wikipedia.org/wiki/Second_law_of_thermodynamics

 

[tittat]

The second law of thermodynamics is an expression of the universal law of increasing entropy, stating that the entropy of an isolated system which is not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium.

Energy dosnt degrade, its dissipated as heat and potential energy.

No,the energy is degrading.
For example: 'X' amount of electric energy is converted in to 'Y' amount of heat.Here a degradation of energy takes place.Here electricity is a high grade energy whereas heat is a low grade energy.Every natural process in this universe is like this.And if this trend continues for a very very big amount of time,the energy of the whole universe will be degraded.And there exists no potential difference of energy,which means the whole world will be paused.
If this must not happen new energy must be created,which is a violation of first law.

electricity is a high grade energy whereas heat is a low grade energy

Why?
