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.
What accounts for most of the mass in the universe?
Current theory states that it's "dark energy".
If the universe is everything and scientists say that the universe is expanding what do you think it is expanding into?
The universe does not expand into anywhere, it is expanding everywhere at every moment. The Newtonian view assumes instant communication of the gravitational field. In such a case, one could pose that the kinetic energy of all the matter in the universe speeding off in all directions is equally balanced by gravitational potential energy that would bind all matter together. I suppose this works when the universe was very close to the size of a singularity. However, the force of gravity travels at the limited speed of light by force carriers called gravitons. So by the time a graviton travels from one side of the universe to the particles on the other side, the particles on the other side have traveled even further away. This would make the gravitational force of a particle felt by particles on the other side of the universe seem weaker than in the pure Newtonian scheme. This is like slowly reducing the force of gravity as the universe expands. Wouldn't this have the tendency to make the particles fly apart more rapidly since you are slowly eliminating the opposition of gravity? Or at least it might help ensure that the universe expands forever.If we throw in a particle horizon where some particles have not yet even felt the gravitational force of other particles very distant from us, this could contribute to expansion. The expansion rate is accelerating, however, which requires some new form of energy we currently know next to nothing about. Hence, it is called "dark energy," and accounts for about 75% of the total mass/energy of the universe.It is possible our universe has an event horizon where more and more distant objects are accelerated to the speed where we will never again see them or feel their gravitational force.The term "expanding universe" is not really the best choice of words, because it does imply expansion INTO something. The universe is, by definition, EVERYTHING that exists. So there is nothing outside of the universe however big or small you conceive it to be.The term "expansion" in this case is meant to imply that there is new space being created between sub-atomic particles throughout the universe as a result of the force from a "Big Bang" being (temporarily) stronger than the pull of gravity. Many different theoretical models have been proposed, but the leading model at the present time is known as the "hot inflationary big bang." The evidence for the big bang consists primarily of galactic red shifts, which increase with distance, and the cosmic background radiation which permeates interstellar space--the so-called 3° K microwave temperature.AnswerIt all started with Albert Einstein's theory of relativity. The theory showed that the universe could expand or contract, which opened the door to the Big Bang theory. Hubble's redshift is an indicator that the universe is in equilibrium between the centripetal force of gravity mg= mv^2/R=mMG/R^2 and the centrifugal force due to velocity -mcDel.v= -mcv/R cos(v). Conservation of energy causes these forces to be equal and mV^2/R=mcv/R cos(v) gives:v/c=cos(v)=z the redshift.At v=c the cos(v) is 1 and the mass is traveling radially. The larger the velocity, the larger the redshift v/c = cos(v).The redshift is the consequence of the Conservation of Gravitational Energy or the Boundary of energy or the Limit of energy or the Continuity of energy, etc, in short the first derivative of the energy set to zero, the Invariant Condition.This can be derived by revising Newton's Gravity theory E= -mMG/R by adding the vector energy mcv giving E= -mMG/R + mcv, this is I call the Quaternion Gravitational Energy as it is the sum of a real and vector energy, ala William Rowan Hamilton's Quaternions.Einstein adopted Newton's Gravitational energy and had to add the "cosmological constant to account for the centrifugal force, or the fact the fact the universe had not collapsed due to Newton's Gravity.The so-called "dark energy" is the vector kinetic energy given by mcv. Today we could call the gravitational Energy E= -mu/R + mcv the 4-vector energy momentumP = E + pc= E + mvc.AnswerThe observational evidence is such that we see "stuff" of similar type, at similar distances "back in time", in all the directions we can look. A steady increase in metalicity as we approach our own age, CMBR temperatures similar to the "Hubble shift" and so on. Distant objects are anomalously large, as if they were being magnified by the size of the Universe they were in. This means that the most simple theory that does not require that we are in a "special place", is that all those other places see exactly the same thing we do.This means that there was no pre-existing empty space, the "Big Bang" really was no sort of Bang, and the distance between "super clusters" is increasing with time... what scientists call "gravitationally bound systems".ANSWEROn a vast scale, the space between structures in the Universe is increasing and the rate of increase is accelerating. This is supported by the best available observational evidence. The Universe is a self-contained, unbounded system. There is no external frame of reference to give meaning to the idea of its expanding into some "where."
What is the total energy input into the atmosphere from all sources?
519 Watt/
How many solar sistems are there?
In the observable UNiverse there are somewhere in the order of 1011 galaxies, a typical galaxy might have 1011 stars, and it seems likely that most stars have planets and would therefore qualify as "solar systems". That makes for a total of roughly 1022 stars or solar systems (that is a one, followed by 22 zeroes), just in the observable Universe. Note that the total Universe is probably much larger, but it isn't currently know how much larger. All of the above are rough estimates, of course.
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.
Why is the total mass energy of the universe is changing?
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.
What is the total amount of molecules in motion?
Every molecule in the universe is constantly in motion. Every one contains some amount of thermal energy, and thus they are all in motion.
The total amount of energy in the universes eye?
The total amount of energy in the universe eye is zero.
What is the total amount of energy in the universe never changes called?
You are thinking of the conservation of energy law which states energy can neither ber created or destroyed.
Is the amount of energy in the universe changing or not?
Yes, the amount of energy in the universe is constantly changing. This does acknowledge that matter and energy are discrete and separate things, but as Einstein made famous per the matter-energy equivalence equation E=mc^2, they are interchangeable. As stars "burn" they undergo fusion processes in their core which convert small amounts of matter into energy, but perform this on very large scales; imagine multiplying this effect by the count of stars in the universe. Opposite effects also exist, such as black holes which increase very slightly in mass per the same equation in the form of energy absorbed as electromagnetic radiation, although whether there is a net increase in mass is now thought to depend on their size because of an effect in which they, too may emit small amounts of radiant energy.
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
The amount of energy in the universe is?
The Total amount of energy in the universe is E=mc2 =1.9 E70 Joules.
According to the law of conservation of energy the total amount of energy in the universe?
true
What is the majority of the energy in our universe?
Something called "dark energy" which provides almost 70% of the total energy in the observable universe and is causing the expansion of the universe to accelerate (instead of decelerate as expected in the basic big bang model of the universe).
Explain why the law of conservation of energy means that we do not have unlimited source of energy?
Answer: The law of conservation of energy means that we do not have unlimited energy because there is a finite amount of energy in the universe, it is merely converted into other forms of energy or matter. Answer: Actually there are two important energy laws - the First and Second Law of Thermodynamics. You should understand both of them to understand what goes on in our Universe, with respect to energy. The First Law (= Conservation of Energy) means that no new energy can be created (or destroyed, for that matter). We can use whatever energy is available in the Universe, but we can't create any new energy. Thus, the total amount of energy in the Universe is limited. The Second Law states that useful energy is constantly being converted into unusable energy. Thus, even though energy can't be destroyed, it will eventually get "used up" in the sense that it is no longer usable. As a result of this, the total amount of energy in the Universe is limited.
The law which states that the total amount of energy in the universe does not change?
The Law of Conservation of Energy
