It isn't known whether the mass-energy of the Universe is changing. Normally, mass and energy are conserved, but it isn't currently known for sure whether this also applies when the General Theory of Relativity is used - which has to be applied when analyzing the Universe as a whole. It seems that it is tricky to even define an "energy function", i.e., assign a definite energy, to a system when using the General Theory of Relativity. This probably doesn't mean that you can use this to get "free energy", only that energy isn't as clearly defined as in classical physics.

Is the total mass and energy in the universe constantly changing?
The Law of conservation of mass-energy indicates that the mass-energy of the universe is constantly changing to maintain the mass-energy constant.
What does the total amount of energy and mass equivalent energy in the universe never do?
The total energy and the mass equivalent energy in the universe remain constant. That "total" energy never changes.
Is the total amount of energy in the universe constant?
There is no known principle that allows mass/energy to be created or destroyed. Theoretically, the total amount of mass/energy in the universe must remain constant. Note: the ability to derive work from energy depends on irregularities in the distribution of mass/energy throughout a volume. As entropy increases, mass/energy will dissipate throughout a given volume, and the ability of that energy to produce meaningful work diminish.
Does burning wood violate the law of conservation of energy?
No, nothing can violate the law of conservation of energy, it's a law! Energy can convert to mass, and mass can convert to energy, but the overall total of mass and energy in the universe is constant.
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.
What accounts for most of the mass in the universe?
Current theory states that it's "dark energy".
Does the law of conservation state that the total amount of energy in the universe is always the same?
Almost. The law actually refers to the conservation of mass/energy. Energy could be converted to mass, and thus suffer reduction. Actually, the energy of the universe may be increasing gradually, as hydrogen fusion liberates a small fraction of mass (the mass defect) through standard stellar nucleosynthesis.
Does the total energy of the universe stay constant?
According to the law of conservation of mass, the energy in the universe does not gets created or destroyed. It just transforms from one form to another. Hence the total energy in the universe is uniform.
Does mass increase as universe expends?
It is normally believed that the Universe's total mass remains constant.
The total amount of energy in the universe is always the same?
The energy called heat, more specifically known as Kinetic Energy - the energy of Heat.Answer2:The energy of motion is cmV = cP, a vector energy. The sum of the particle energy is c x Sum of Pi
How can the gravitational potential energy of an object be changed?
Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work.Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work.Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work.Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work.
Except for mass energy all energy in the universe is either?
kinetic or potential
