Matter Anti-Matter Annihilation

[rocketwaveuk]

The pure energy coming from a collision and how is it measured or is it just "A Formula" and is any of that energy Dark Energy or even Dark Matter, the reason for the question is because the Dark Energy/Matter vs normal Energy/Matter seems to align with what is seen now after the Big Bang Annihilation. Does anyone know of a research into this field.

The result of matter-antimatter collisions is not "pure energy" but rather energy carried by particles of the Standard Model. From a discussion of matter-antimatter annihilation for rocket propulsion
(https://en.wikipedia.org/wiki/Antimatter):
"Not all of that energy can be utilized by any realistic propulsion technology because of the nature of the annihilation products. While electron–positron reactions result in gamma ray photons, these are difficult to direct and use for thrust. In reactions between protons and antiprotons, their energy is converted largely into relativistic neutral and charged pions. The neutral pions decay almost immediately (with a lifetime of 85 attoseconds) into high-energy photons, but the charged pions decay more slowly (with a lifetime of 26 nanoseconds) and can be deflected magnetically to produce thrust.
Charged pions ultimately decay into a combination of neutrinos (carrying about 22% of the energy of the charged pions) and unstable charged muons (carrying about 78% of the charged pion energy), with the muons then decaying into a combination of electrons, positrons and neutrinos (cf. muon decay; the neutrinos from this decay carry about 2/3 of the energy of the muons, meaning that from the original charged pions, the total fraction of their energy converted to neutrinos by one route or another would be about 0.22 + (2/3)⋅0.78 = 0.74)."

No mention of "dark energy" or "dark matter".

Matter antimatter annihilation has nothing to do with either dark energy or dark matter. What led you to believe it did?

 

[rocketwaveuk]

sorry if i confused you , i asked some questions , i did not state any belief, and also gave the reason at the end for the question.
renormalize was kind enough to answer with a explanation i can understand.

Also:

pure energy

there is no such thing, just like there is no "pure velocity", etc.
