    Constant
In summary, the conversation discusses the concept of mass-energy equivalence and its relation to the first law of thermodynamics. It clarifies that the equation E=mc^2 does not represent a conservation law, but rather the constant of proportionality between an object's rest mass and the energy it contains. The conversation also emphasizes that this equation only applies to the energy due to mass in the universe, not the total energy in the universe.

As the speed of light is constant in the universe, E/M should be constant.
Suppose that in some corner of universe mass is being converted in energy. So there must be some another corner of universe where mass is being converted into energy at the same time.Is my argument correct??

Sorry, but this makes no sense.

You are confusing an equation that describes the conversion of one to another with a conservation law. That equation is not a conservation law just because c is a constant.

Zz.

E=mc^2 is an equation that describes the constant of proportionality between an object's rest mass, and the energy that mass contains.

The sum total of mass and energy in the universe has to remain unchanged by the first law of thermodynamics, but mass energy equivalence does not indicate that there must be a certain proportion between the two when you sum all the mass and energy in the universe.

thanks,
i was thinking that E represents energy of universe while M mass of universe ant that equation works as conservation of energy.

E would represent all the energy due to all the mass in the universe, not the total energy in the universe. Hope that makes sense

yes got now
Thanks :thumbs:
 

What is the E/M Constant?

The E/M Constant, also known as the Mass-Energy Equivalence Constant, is a physical constant denoted by the symbol c². It is equal to the speed of light squared and is an important factor in the famous equation E=mc², which relates energy and mass.

How is the E/M Constant calculated?

The E/M Constant is calculated by multiplying the speed of light (c) by itself. The speed of light is a fundamental constant of nature and is approximately 299,792,458 meters per second. Therefore, the E/M Constant has a numerical value of approximately 8.98755 x 10¹⁶ square meters per second squared.

What is the significance of the E/M Constant in the universe?

The E/M Constant is significant because it shows that mass and energy are interchangeable and closely related. It has been confirmed through various experiments and is a crucial component of many theories and equations in physics, such as Einstein's theory of general relativity.

How does the E/M Constant affect mass conversion in the universe?

The E/M Constant plays a critical role in mass conversion in the universe. It shows that mass can be converted into energy, and vice versa, through processes such as nuclear reactions and particle collisions. This constant allows scientists to understand and predict the behavior of matter and energy in the universe.

Is the E/M Constant a universal constant?

Yes, the E/M Constant is considered a universal constant because it has the same numerical value regardless of the reference frame or location in the universe. It is a fundamental physical constant and is crucial for understanding the laws of nature and the behavior of matter and energy in the universe.
