e=mc^2 - thoughts on mass creation?

  1. Can anyone help explain the process of energy converting to mass?

    Probably not.

  5. There are no theories? None? Both energy conversion into mass and mass conversion into energy have been experimentally achieved and mathematically formulated. Has no one made logical conjectures about the processes through which this transition manifests itself?

    Look up "standard model of particle physics".

    ass does not covert to energy and no worthy experimental or theoretical physicist believes otherwise. The mass before and after acceleration is invariably referred to as "rest mass".

  10. so when an electron and positron collide.. they annihilate and convert to energy completely. Also, special conditions allow electrons and positrons to be created by a double energy gamma wave. So evidently, there is a mechanism to convert between mass and energy. I'm just wondering how this is possible.. Are massive particles comprised of photons, or does photonic energy manifest mass through its effect on timespace. Those seem to be the most likely outcomes...

    I wonder too. Especially with the statement" an object gains more mass as it approaches the speed of light"

    What are you talking about? Matter-antimatter reactions have been observed plenty of times. Even the power we draw from nuclear energy is due to mass conversion. There is a reason we claim conservation of matter/energy rather than the conservation of matter or energy as seperate items.

    Electron-Positron annihilation is a common, everyday occurrence in modern medicine, used in PET and PET/CT procedures all around the globe on a daily basis. The pure rest mass of the electron and of the positron are both completely converted into pure energy, releasing two 0.511 MeV (511 KeV) photons that go off in opposite directions (conservation of momentum).

    Likewise, anti-protons are routinely created at FermiLab in Chicago, and then collided into protons, where their rest mass and kinetic energy are completely converted into energy and mass particles with kinetic energy.

    This is no longer the forefronts of science - it's decades-old technology.

    It's very common here on Earth, and elsewhere in our Universe.

    No idea. Observe, if you will, how molecules transform into atoms (with a microscope, mind you..), and how atoms into... Whatever they are. Make some broad observations and maybe something'll come up.

    Energy is tied up (in molecular level) when two atoms pull a group of electrons at a constant force, while repelling each other. This undoubtly occurs at lower levels as well. To fully comprehend this, we would need a proper understanding of repelling AND pulling forces, which are totally beyond me. (when the forces are imbalanced, the construct begins to crumble.)

    As to how it happens; imagine two atoms bumping into each other at some speed. These atoms happen to form a molecule (Na and Cl, for example..). They collide, and bounce, only to find themselves unable to escape each others fields. They are effectively stopped, energy is "stored", and what energy remains will direct the molecule towards someplace.

    GeistKiesel: The following is an interesting statement
    Do you have some alternative explanation for the energy produced by the sun, H-Bombs, radioactive decay, et cetera?

    The mainstream view of the above processes is conversion of mass to energy. The energy output of the sun is particularly difficult to explain without claiming mass conversion to energy.

    In the 19th century when science discovered that the Solar System was millions (not sure if they knew billions at that time) of years old, the energy output of the sun was a major puzzle. Assuming the most energetic chemical reaction known, the sun would burn out in less than 100,000 years.

    mc^2= E

    My reasoning has me seeing "c^2" is a theoretical maximum "sphericle" area that is at unity.

    In the above case "E" represents the total "sphericle" mass and or field at complete rest which would be theoretically zero.

    If such a "sphericle" area gets compressed and contained by say 10 "Nm" its outward velocity to unity should equal 10 "Nm" of force and or elecromotively 10 joules, so "E" would equal 10 Nm or 10 Joules.

    But what really is interesting is that a mass now exists with a certain density because lets say the above mentioned 10 joules is a result of an electromagnetic wave being propagated, and if we look at the huge area we are working with, it should give good understanding why "c" the speed of light is at maximum velocity when propagated in a near vacuum.

    Space in our Universe is an area that no matter where we measure it, is at best very near unity, suggesting the whole universe is a single mass with areas of different densities and or potentials where around 90% of it is near unity while the rest is at some considerable compressed state with a significant potential, and the more compressed the mass the greater the potential and or the greater the energy reserve representing "E", In fact it gives reason why "c" is propagated much slower where the area is at some compressed state as in solids.
