Matter vs. Anti-matter

The Science Asylum - What makes anti matter so special?!


The theme escapes to the trend of what has been published. Physics! Year by year, more and more discoveries are made. Is it a new particle, a distant galaxy or a unexplained principle.
The theme "matter - antimatter" is relatively recent in view of the time we know the least well our Universe (notice I said "our Universe"). Curious will think, will already know minimally well ??? And leaving the part of phylosophysics and returning only to physical here we go !!!

First of all it should be noted that the antimatter term is just a convention. It's setting on the line of the real numbers to the positive is from right to left and the negative from left to right, or to define the north pole is at the top of the globe and the South Pole is down (by the way, the top and bottom part is a term that really can not be applied because the Universe has no reference or center).

There is nothing that gives the antimatter unique characteristics that no matter the "normal". The only peculiarity is that the load is exactly opposite !. Moreover, has the same mass, size, emit the same radiation and energy, as is everything!
While an atom of matter consists of a neutron, proton and electron a antimatter atom is constituted by an anti-proton, anti-neutron and a positron (as opposed to electron).

Matter is an energy state, and as such, when the Big Bang occured, it released all the energy that was contained, and it should have been createded equal amounts of matter and antimatter.
The only problem is that because they have exactly opposite charges when they touch contact teach other, they annihilate and release energy !!! Rather the spectrum of gamma rays:

As such, with equal amounts, the matter should not exist, and quoting Descartes, "I think, therefore I am", and after all, here we are and that's why we have a problem!
A good explanation for this battle that has been won by matter rather than the anti-matter might be behind the fact that there may be more matter than antimatter in the universe. Some say that for every 1 million anti-matter particles, there were 1 million and one particle of matter. But still, this goes against the principles of physics!

However, keep hopes !!! These two differ in one very important aspect !!! Radioactive decay !!! It has been tried and indeed antimatter has a considerably faster decay! Yet it is not enough to answer our questions ...

On the other hand, the author of video as well as other physicists argue that there is still an equal amount of matter and antimatter in the universe. And that perhaps some of the galaxies we observe are composed entirely of antimatter. Interesting idea!
However, if that happened, it would be expect that at least at the border of the galaxy / cluster / supercluster, the two types of matter meet and annihilate each other! What does not occur because there is no data of dubious emissions or sources of gamma radiation in space!

Finally, another issue that arises is whether the anti-matter has an opposite gravitational force than usual, which is would be to observe the attraction between two bodies.
In my opinion, not acknowledging any negative mass elements (or contrary to our, as they prefer to say), I do not see this happening.
On the other hand, if exists galaxies of antimatter, how do they exist if each body would repel other bodies?
If so, how does an antimatter atom would have the same properties as conventional matter? I know the strong nuclear forces are prevalent, however it would still interfere with the atomic radius, bonding radius, electron removal of energy, etc ... But do not let being a layman in physics, I am always ready to learn and if there are opinions that contradict my argument, I will be happy to hear them!

And you??? What do you think???
