Oct 31, 2015 · 0. I think pure energy refers to energy existing without matter. Energy is usually regarded as a property of an object. Light, having no mass, could then be regarded as pure energy. The energy is conserved in the form of momentum. When a photon strikes an atom it gains energy, nothing else and the photon ceases to exist.
A virtual graviton or their pair would also be "pure energy". "Pure energy" is meant to have the property that it's not hard for other objects to absorb it (or emit it) without changing their character qualitatively. It's like the energy in the sugars or chocolate that you may quickly transform to the energy to run. An extra proton in the state ...
Pure energy can be the light because it has no mass. – Energizer777. Nov 7, 2015 at 19:34. @Energizer777 Nope. Not even close. Light is electric and magnetic fields. The basic problem with this kind of question is that "energy" isn't a thing, it's a property. – dmckee --- ex-moderator kitten. Nov 7, 2015 at 22:53.
Oct 30, 2019 · Two kind of things can happen with photons. If an atom makes transition from higher energy to lower energy, in the process, atoms energy will be decreased and photon will be created (emitted). An atom from lower energy state, can 'absorb' photon and go to higher energy. In that process, photon will vanish, we say atom absorbed it.
Where did this Energy come from? Energy requires matter or something to manifest itself. Light requires photons, electricity requires electrons etc. What is this something. What if there was a Field that had information in it. That field went through some transformation that resulted in matter from which came Energy.
2. "but is there any conception of what energy was like prior to the big bang?" If one defines the big bang as the 'beginning' of spacetime, then this question doesn't make sense. However, if one considers the big bang as something else (e.g., Penrose's CCC), then talk of 'prior to big bang' may have meaning. – Alfred Centauri.
Oct 24, 2021 · Given amount of physical rest mass,- how much pure energy you can convert from it, is given by Einstein famous eq: $$ E=mc^2 $$ or if expressed in terms of amount of massless photon particles: $$ n = \frac {mc^2}{h\nu} $$ But again, this explanation is subjective and I doubt if objective one exists in your question.
Jan 15, 2020 · Matter is not converted into energy. Mass is converted into energy. This can be observed in, for example, nuclear fusion of hidrogen, resulting in a helium nucleus. With two protons (of, let's say, mass=1) you'd expect the resulting nucleus to have mass=2. But it doesn't. The resulting mass is smaller than 2.
For pure energy, every day is groundhog day - there is an intrinsic period associated with energy states but no sense of succession. How does "real" time enter the picture? We know that there is an opportunity in spacetime for "timelike" intervals between events, in this zone a succession of events can be established that can maintain a cause-effect relationship in all reference frames.
Aug 20, 2021 · $\begingroup$ @Scarlett the only way mass is converted into energy is when it is destroyed or annhilated. This happens in a nuclear reaction. In those reactions, if you weigh the mass before and after, they won't be the same. This difference in mass gives rise to energy. This destruction of mass serves as the source of energy. $\endgroup$
