energy can neither be created nor be destroyed then where from energy comes from?

Answer 1

All needed energy is already here, the sun is here that creates heat and light energy. Notice you left out part of that law, Energy cannot be created or destroyed, only CHANGED so energy that is in light can be changed into heat energy, that energy can in turn be transfered to other forms, steam energy that can be transformed to kinetic energy or potential energy. See all energy we need is here already!

Answer 2

I assume that you are asking where all the energy in the universe came from, originally. It's a question that does not have a scientific answer. Philosophically, there are some unscientific hypotheses to explain the existence of energy, for which nobody can find actual disproof.

One explanation is there is a God who created the universe. That one is popular because it has the weight of tradition behind it, and because organized religions have made promises of a pleasant afterlife to believers while warning that unbelievers will be tortured for eternity after death. (Psychologists call this "the carrot and the stick" persuasion.)

Another explanation is that existence equals energy plus form. Since existence exists is a tautology (existence has no alternative), energy exists by the same tautology. There never was any chance that energy would not exist.

Does this argument have an ontological defect? I'm not sure that it does. I don't assume anything about the form of the energy, except what can be inferred from measurements of vacuum energy; i.e., that the default form for energy is random distribution in random flux.

The thing about randomness is that it does not preclude order. Order is merely proportionately scarce when energy is randomly distributed. But given enough permutations in which energy occurs randomly, a small fraction of them will be highly ordered. One way for vacuum energy to order itself is to occur in superposition at a high density in spacetime. A great "equivalent mass" of energy shows up in the same place at about the same time, causing an event horizon to form around it, pinching it off from its parent region.

I think that's how universes begin.

This is speculation, and since it can't be tested it isn't scientific. But there's nothing wrong with it, and it seems more elegant and more in accord with modern science than the God hypothesis is.

Answer 3

We don't know where all the energy (matter with mass is just a form of energy) came from originally. We have reasonable hypotheses about the history of the universe back to its first fraction of a second, but we really don't know where all the energy came from in the first place.

Some people have guessed that all the energy is some sort of quantum fluctuation, but that's really just a guess without any solid testable theory behind it.

Answer 4

Actually energy in einsteins equation is not created by any outside force but rather the atoms in the molecules of a given body are actually changed or should i just say "excited and accelerated"to the extent that these molecules sepparated from each other to change into another form of energy. Atoms themselves are energy and that they only gain tangible form by joining together.

Answer 5

Energy CAN be created. According to Einstein's formula, E=MC^2.

This happens in nuclear fusion, and fission. The total energy and mass currently in the Universe, is constant.

ALL the mass and energy is still the same as it was when the "Big Bang" occurred.

Answer 6

I think the main source of energy is the Sun
or
It has been shown that the positive matter & photon energy and negative gravitational potential energy sum exactly to zero.

Answer 7

all of the energy that exists now was created at The Big Bang. The total amount of energy has not changed. It is only converted from one form to another.

Answer 8

From Mass. Actually, the sum total of Mass and Energy in the universe remains constant. They can be inter converted as given by E = mc^2.

Answer 9

its true energy can neither be created nor be destroyed but newton did say something more.that it can be converted from one form to another.so energy was always here and its was been converted into one form and another. maybe that energy did come from real fusion or stuffs by Einsteins equation e=mc^2...

Answer 10

It has been shown that the positive matter & photon energy and negative gravitational potential energy sum exactly to zero.
