Exploring Mass & Energy: Is Energy Created or Has it Always Existed?

In summary, Daniel is saying that mass and energy can be transformed into one another and that the Big Bang created the universe. If you do not agree with Daniel, good luck!

I was pondering to myself today while reading Einstein's Evolution of Physics, so I was looking at E=mc^2 and it got me wondering. If mass and energy are the same, but mas cannot be created or destroyed through the law of mass conservation does the same hold for energy? Is energy created or has it always existed, has it existed around the time of mass or perhaps even before it?

Think of this perhaps the beginning of the universe it was nothing more than freebound energy, and the energy finally collided, and solidified into a mass, this mass then broke apart in the big bang which formed the planets, stars and systems and so forth. Now this energy is still present coming form this mass continuing to separate it and combine it with other masses. This energy came to form gravity, light, sound and the other forces which are contained within in the universe.

So, I got to thinking maybe mass did not always exist as mass what if it was energy but where did the enrgy come from some sort of rift? Maybe the energy was always there as it seems more sensible that energy would have existed before the mass as the mass is what created the universe and that mass and energy are equal. So in my theory I am stating that this energy is the beginning of everything we know, the forces, the matter and time and space itself.

Let me know what you think?

The idea of "mass cannot be created or destroyed" and "conservation of energy" were taught to you before you were taught that "E=mc^2", which now clearly indicates that mass and energy can be transformed into one another. What is actually being conserved is the total sum of energy+mass. If you have a system that has no conversion between energy and mass (which is most of the time in our classical world), then energy and mass are conserved separately, which is obvious.

However, if you are dealing with more "exotic" process in which mass and energy are interchangable, then the more general principle that is relevant is the conservation of mass AND energy together.

On other thing, please do not forget the definitions of these quantities. Mass is the proportionality between force and aceleration. Energy is the stored ability to produce work.

Too bad these 2 definitions have nothing to do with [itex] \mbox{E}=\mbox{m}\mbox{c}^{2} [/tex]...

Exactly. I have to add that when energy is transformed to mass and vice versa, in none of this processes there is any kind of destruction of mass or energy.

"Is this possible?"
James, I suppose, if that's what you wish to believe what happened before the Big Bang or creation of the Universe and did not accept what I would have to say about my ideas, I say good luck!

When the Big Bang occured, time, space, matter and energy as we know it were created in our known universe. Thus to talk about them " before" "then" go ahead if you want to!

Related to Exploring Mass & Energy: Is Energy Created or Has it Always Existed?

1. What is the concept of conservation of energy?

The concept of conservation of energy states that energy can neither be created nor destroyed, but can only be transformed from one form to another. This means that the total amount of energy in a closed system remains constant.

2. How do scientists determine the origin of energy?

Scientists use various methods and theories, such as the Big Bang Theory, to explain the origin of energy in the universe. While the exact origin of energy is still a topic of debate, it is generally believed that all energy in the universe was created during the Big Bang.

3. Can energy be converted into mass?

Yes, according to Einstein's famous equation E=mc², energy and mass are equivalent and can be converted into one another. This has been proven through experiments, such as nuclear reactions, where a small amount of mass is converted into a large amount of energy.

4. Is energy a finite resource?

It is believed that energy is a finite resource in the universe. While energy cannot be destroyed, it can be transformed into unusable forms, such as heat energy, making it unavailable for use. This means that we must use energy efficiently and find alternative sources to sustain our energy needs.

5. How does the concept of entropy relate to the creation of energy?

The concept of entropy, which is a measure of the disorder or randomness in a system, is closely related to the creation of energy. The Second Law of Thermodynamics states that in any energy transfer or transformation, some energy will be lost as heat, leading to an increase in entropy. This means that the creation of energy will always result in an increase in entropy in the universe.
