According to what the universe's total amount of energy does not change?

It is because of the law of conservation of mass and energy, which states that the total amount of energy and mass in a closed system remains constant. This is because of Noether's Theorem. It states that some value in a symmetrical and closed system remains constant. Because of this, the mass and energy content of the universe remains constant as long as the laws of physics in it remain constant.

Galaxies are smaller, denser and more active, on average, stars have not that many heavy elements than nowadays. This is clear-cut evidence for a change of the universe. Alternative theories such as the steady-state model cannot explain it.

What atomic change produces the largest amount of energy?
The atomic change that produces the largest amount of energy is a nuclear atomic change. This is when an atom is hit with another elementary particles and releases a large amount of energy.
What is needed to create change in a system?
The amount of energy is used to make the change.
The amount of energy which a system has to have in order for a chemical change to take place?
The activation energy.
What is the name of heat energy that changes ice into water and water into steam?
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
During an energy transfer what happens to the total amount of energy?
Energy can not be destroyed, so the total amount of energy before a change is equal to the amount of energy after the change. However, some energy is changed into a useful form, but some may be wasted and not used. For example, a light bulb, changes electrical energy into light energy, but some of the energy is changed to heat and some to sound, these are not useful and are wasted, but are changed nonetheless. So a transformation from mechanical energy to heat will have the same total energy at the start as at the finish, but unless it is 100% efficient some of the original energy will be 'lost'
The total amount of energy in the universes eye?
The total amount of energy in the universe eye is zero.
How does the total amount of energy change as the energy is changed from potichal to kinetic?
The total amount of energy doesn't change in this case.
An airplane changes energy into different forms The total amount of energy does not?

What atomic change produces the largest amount of energy?
The atomic change that produces the largest amount of energy is a nuclear atomic change. This is when an atom is hit with another elementary particles and releases a large amount of energy.
Compare the total amount of energy before and after physical and chemical changes?
Physical Change-- Same amount of energy, but in different form Chemical Change-- Different amount of energy, and in a different form
What change when the amount of a substance change?
total thermal energy
As the temperature of a gas decrease what change occurs in the amount of kinetic energy?
The amount of kinetic energy increases.
As the temperature of a gas decreases what change occurs in the amount of kinetic energy?
The amount of kinetic energy increases.
How often does the total amount of energy in the universe change?
We do not think it does change.
What phase change will the greatest amount of energy be absorbed by 1 gram of water?
The liquid to gas phase change will absorb the largest amount of heat energy.
Does the amount of energy change when one energy changes to another?
No. It just gets moved around. The total amount of energy stays the same.
According to the law of conservation of energy the total amount of energy in the universe?
true
