Where does energy come from if it cannot be created or destroyed?
If energy cannot be created or destroyed, then by definition it couldn’t have “come from” anyplace, because by definition it must have always existed and must continue to exist, in one form or another, forever.
How was energy created in the universe?
The standard cosmological answer is the energy was created in the very first instance of the universe by a quantum vacuum fluctuation. It is actually imprecise to say energy cannot be created or destroyed it happens all the time. The equation that governs this is:
Is it possible to create eternal energy?
It's possible energy is eternal, or maybe energy can be created in the meta universe, ubaverse, and the energy can not be created in our small universe. So if you want you can put God there, though that strategy hasn't worked in the past, God has moved from the mountains to the sky to the universe etc.
Why does energy remain constant even when it is converted?
Energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted. Energy remain constant because it transfer one form to another form.

Where did energy came from if it Cannot be created or destroyed?
The amount of energy/matter in the universe is constant and derives from the mysterious big bang.
Can energy be created from nothing?
Even if the matter is somewhat more complicated than previously thought, energy cannot be obtained from nothing, even though it can become negative. The new research results now place tight bounds on negative energy, thereby connecting it with quintessential properties of quantum mechanics.
Where did energy originally come from?
What was the first source of energy? Energy has been around since the dawn of time. The first source of energy was the sun, as it provided heat and light during the day. People rose and slept with the light, relied on wood and dung burning for heat, and water power to generate basic mills.
Why energy can neither be created?
Energy can neither be created nor destroyed i.e. the total energy of an isolated system remains constant; however, it transforms from one form to another. The same phenomena can be applied when we burn a candle, chemical energy of wax is spent and converted to light energy.
Are humans matter or energy?
In life, the human body comprises matter and energy. That energy is both electrical (impulses and signals) and chemical (reactions). The same can be said about plants, which are powered by photosynthesis, a process that allows them to generate energy from sunlight.
Can energy exist by itself?
No matter what the interactions are, energy is never seen to exist on its own, but only as part of a system of particles, whether massive or massless. Energy can be converted from one form into another, even from rest mass energy into purely kinetic...
Can matter be created from nothing?
So yes, humans can manufacture matter. We can turn light into subatomic particles, but even the best scientists can't create something out of nothing.
Are humans a form of energy?
Quantum physics states that mass and energy are interchangeable, and consequently that mass is merely a manifestation of energy. This means that everything, including humans, is simply energy stored in mass particle form. According to the theories associated with the universal energy field.
Can energy ever be destroyed?
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.
Is everything made of energy?
Albert Einstein And it is quite clearly showing that everything is energy at the most fundamental levels.
How much energy is in the universe?
It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the universe.
What is the biggest source of energy?
SunSun (solar radiation) is the biggest source of energy on Earth's surface. It is also known as the ultimate source of energy on Earth's surface because we know that green plants use sunlight for photosynthesis, which is the process by which they make food for their growth.
Can matter be created from nothing?
So yes, humans can manufacture matter. We can turn light into subatomic particles, but even the best scientists can't create something out of nothing.

Does the universe have zero energy?
Thus, "the gravitational field has negative energy. In the case of a universe that is approximately uniform in space, one can show that this negative gravitational energy exactly cancels the positive energy represented by the matter. So the total energy of the universe is zero."
Energy cannot be created. Then where did it all come from?
Someone asked me this question: If energy cannot be created then where did the Universe come from? Are there any websites, papers or documents concerning this question, answer? The first law of thermodynamics which is a version of the law of conservation of energy, adapted for thermodynamic systems.
If energy cannot be created or destroyed, where does it come from?
Mike Follows. Sutton Coldfield, West Midlands, UK. Energy can be transferred between different stores. Energy and matter are equivalent, so nuclear energy, for example, starts off as matter.
How long ago did the universe explode?
Therefore, the currently accepted scientific theory is that that universe “exploded” into existence about 13.7 billion years ago.
How was energy created?
The standard cosmological answer is the energy was created in the very first instance of the universe by a quantum vacuum fluctuation. It is actually imprecise to say energy cannot be created or destroyed it happens all the time.
How is mass converted to energy?
Mass is converted to energy in the cores of stars. For instance, in the Sun, hydrogen is converted to helium with the release of gamma rays. These heat the Sun which shines. This energy warms and lights the Earth.
What is the energy of a closed system?
Energy is a number that we calculate for a certain closed system, just like enthalpy and entropy. The observation of many systems has shown that their energy is constant, as well as that their entropy always increases. Since this is valid in all the systems observed, a law is postulated that says that this number that represents the energy associated with a closed system does not vary, that is, neither increases nor decreases; or, in philosophical terms, it is not created or destroyed.
How to calculate kinetic energy?
For example, if we have a body in the hand we can calculate its kinetic energy, which is given by the formula E = 1 2 m V 2 . Since its velocity is zero, consequently, its kinetic energy is zero. However, if we take into account that this body is located at the Earth's equator traveling at a speed of 1667 km / h, its kinetic energy would be 107 167 Joules per kg of mass.
What happens when you die?
When we die we start to decay from the micro organisms and the worms living in ground. Humans like to think we can find the start of something or the ending of something but really there was never a start or ending to begin with.... Energy cannot be created according to today's physics. In fact Energy is = 0.
What is the definition of energy?
A widely used definition of 'energy' is the capacity or ability to do work. One of most basic laws of science is the Law of the Conservation of Energy according to which energy cannot be created or destroyed; it can only be changed from one form to another. Energy isn't a thing that things are made of.
Why does a magnet have a magnetic field?
It is true that the magnetic field of a magnet is due to the little spins inside, each one thus having a magnetic moment, aligning and thus adding up and causing a macroscopic magnetic field. Wherever there is a magnetic field there is energy. Same for electric field, which will accelerate charges. Or the combination of electric and magnetic field, which can radiate, carry energy, and use that energy to carry a signal so you can watch TV.
How many reputations do you need to answer a highly active question?
Highly active question. Earn 10 reputation (not counting the association bonus) in order to answer this question. The reputation requirement helps protect this question from spam and non-answer activity.
Does the magnetic field have energy?
Should not be strange that the magnetic field has energy. The gravitational field also does, and you see it when the earth attracts a body making it come down, changing to kinetic energy. In conservative systems or forces, there is a potential whose negative gradient is the force.
Why is the energy of the fluid not constant?
Also, since the universe is expanding, even if we restrict attention to the photon "fluid", and treat its expansion as adiabatic , the total energy of the fluid is not constant, because the expansion redshifts the photons. Before the "surface of last scattering", when the CMBR was emitted, the photons were in thermal equilibrium with the matter ( which was a plasma then), so heat was being transferred from the matter to the photons to counteract the redshift of the photons as the universe expanded . But when the matter "recombined" (a strange term since it had never been "combined" before) into atoms and stopped being a plasma, the photons became decoupled from the matter, and ever since, they have been losing energy relative to the matter because of the redshift. This "lost" energy has not been transferred anywhere; it is a manifestation of the fact that, as noted above, global "conservation of energy" is a problematic concept in a non-stationary spacetime.
What is the main component of the fluid?
In the reference you gave, since the key focus of the section you pointed out is entropy , the main component of the "fluid" under study is the CMBR--a photon bath which is taken to be in thermal equilibrium, and which contains the vast majority of the entropy in the universe. However, that does not mean it contains the vast majority of the energy in the universe; and, in fact, it doesn't--it contains a couple of orders of magnitude less energy than ordinary matter (which is itself only a few percent of the total energy according to our best current model--the rest is dark matter and dark energy).
What is the mass-energy equivalence equation for annihilation?
Annihilation is a release of energy available to do work, proportional to the total matter and antimatter mass, in accord with the mass-energy equivalence equation, E = mc 2
What laws of physics forbid creation?
One is that the conservation laws of physics forbid the creation of something from nothing.
What is the law of conservation of energy?
The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but cannot be created or destroyed. I have researched all thermodynamic processes to no avail. Thank You.
Where does the conservation of entropy come from?
The conservation of entropy used in cosmology comes from the conservation of energy.
Is the Big Bang model a creation?
This statement is wrong. The current big bang model doesn't deal with creation. At all. It merely states that the very early universe was extremely hot and dense and expanded from there. There is no 'creation' event in the model like people think there is.
Where did energy come from if it Cannot be created or destroyed?
As we know through thermodynamics, energy cannot be created nor destroyed. It simply changes states. The total amount of energy in an isolated system does not, cannot, change. And thanks to Einstein, we also know that matter and energy are two rungs on the same ladder.
Are humans just energy?
Energy. Scientists believe that almost all of your body’s mass comes from the kinetic energy of the quarks and the binding energy of the gluons.
Is energy ever lost?
Conservation of energy is called a law because this rule is true in all known cases. Although in many instances it may appear that energy is gained or lost, it is really only changed in form.
What are the 3 laws of thermodynamics?
Traditionally, thermodynamics has stated three fundamental laws: the first law, the second law, and the third law. A more fundamental statement was later labelled the ‘zeroth law’. The zeroth law of thermodynamics defines thermal equilibrium and forms a basis for the definition of temperature.
Can an atom be destroyed?
All matter is made of atoms. … Atoms cannot be created nor destroyed, and they are indestructible; they cannot be broken into smaller parts. This was based on the Law of Conservation of Mass. It was later learned that atoms can break into smaller parts.
What is darkness made of?
Darkness in made of broken light. It is of non-luminous particles, former photons or other elemental particles, that have become so diffused and spread out into a blanket that individual particles do not exist within it. It is devoid of any spectrum and wavelengths.
What is the ability to bring about change or to do work?
Energy is the ability to bring about change or to do work. …. The Second Law of Thermodynamics states that “in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state.”. This is also commonly referred to as entropy.
How does a bicycle get its energy?
The bicycle got its potential energy (energy due to position related to gravity) by the rider using metabolic energy to move the pedals. The pedals used mechanical energy to move the chain, which moved the wheels.
What happens when you rub your hands together?
If you take your metabolic energy and rub your hands together, you have made metabolic energy into mechanical energy. Your hands will heat up. That is some of the mechanical energy turning into heat energy.
What is potential energy?
There is potential energy in objects at rest that will make them move if resistance is removed. There is kinetic energy in objects that are moving. The molecules making up all matter contains a huge amount of energy, as Einstein's E = mc ^2 pointed out to us. Energy can also travel in the form of electromagnetic waves, such as heat, light, radio, ...
Where does the rider's energy come from?
The rider's metabolic energy came from chemical energy that was stored in the molecules of the food she ate. That chemical energy entered the animal whose meat she ate by the animal digesting a plant and breaking the bonds in its molecules. The plant made the molecules by using light energy from the Sun.
What is the law of conservation of energy?
So the short answer is that the energy we encounter and use everyday has always been with us since the beginning of the universe and always will be with us. It just changes form all around us. That is called the law of conservation of energy.
