It may have to do with the way the universe was created. Certainly if there was a lot of antimatter created, much of it may well have come in contact with matter through the billions of years the universe has existed. That would have resulted in the conversion of that antimatter (along with a like amount of matter) into energy. There may not have been much antimatter around to begin with, too. But, since the amount of visible matter represents less matter than has been calculated to exist in the uinverse, it may be that there is a good bit of antimatter out there somewhere. Not likely, but possible.
That is not currently known. There is a slight assymetry between matter and antimatter, but so far, it seems that this assymetry is not enough to explain why there is only matter, and hardly any antimatter, in the Universe. Without such an assymetry, there wouldn't be either matter or antimatter in the Universe - just radiation. For more information about what is known, and what isn't, check the Wikipedia article on "Baryon asymmetry".
It seems the Universe consists almost entirely out of matter - that is, there are no significant amounts of antimatter. Why there is more matter than antimatter is an unsolved problem.
1. Why is there more matter than antimatter in the Universe? Or: Why is there matter at all? (If there were the same amount of matter and antimatter, and it came into contact, it would quickly get destroyed. 2. If antimatter is so abundant, how come we've never come in contact with it or have been able to observe it?
It is not currently known why there is more matter than antimatter. Some assymetries (differences between matter and antimatter) have been found, but they are very slight, and it is not clear how this could have been enough to create the matter we see today.
The concept of antimatter affects our understanding of time by challenging the symmetry between matter and antimatter. Antimatter particles have properties that are opposite to those of their corresponding matter particles, leading to questions about why there is more matter than antimatter in the universe. This imbalance could potentially impact our understanding of the fundamental laws of physics, including those related to time.
Because (we think) both matter and antimatter was formed initially, most of which was canceled out to form more energy.
Dark matter, matter, and antimatter are all components of the universe, but they have different properties and interactions. Dark matter is a mysterious substance that does not emit light or energy, but exerts gravitational force. Matter, which includes everything we can see and touch, is made up of atoms and particles. Antimatter is a mirror image of matter, with particles that have opposite charges. The relationship between these three components is complex and not fully understood, but they all play a role in shaping the structure and dynamics of the universe.
Plasma. It makes up more than 99% of visible matter in the universe, and most of the invisible matter.
who knows, your guess is as good as mine, but i believe that matter isn't prevailing, maybe there are more antimatter than matter in some distant planet or something.
Antimatter is the opposite of matter and so when the two come in contact with each other, they become nothing but neutral energy. The idea that it is possible to create antiatoms is astounding simply because matter is everywhere. On top of this, it takes a lot of energy. so to create antimatter alone is rather difficult. It's also a difficult thing to sustain for more than a few seconds, if even that long, because it's always surrounded by matter. In other words... The fact that they were able to create it is simply incredible. Further more, if we look into the theories there are about antimatter, we can see some amazing things that could end up being true. One of these is the idea that the big bang began with a neutral Higgs particle which somehow became imbalanced. suddenly, this imbalance created a supermassive amount of energy. Because the Higgs particle is so heavy, much antimatter and matter were expelled. Because there was an imbalance, the amount was not perfectly equal and so it wasn't all cancelled out. The idea is that there was more matter. The matter that was equal to the antimatter was cancelled out by the antimatter and the rest of it became what we see as today's universe. Due to the fact that it was thrown outward so rapidly however, not all the matter and antimatter touched. Which meas that some anti matter flew way out to the far reaches of the universe...(Which was, scientifically speaking, much much smaller when if first started. Then it got really big really slowly... that is the meaning of big bang... slow expansion) So there could be regions of our universe bigger than our galaxy that are completely composed of dark matter. It really isn't important, but one day a million years from now, when people can travel space that far out... then it may just matter...
Antimatter has particles with properties that are the opposite of normal matter (in some of their properties). For example, normal matter - the one we are most familiar with - consists of atoms that have protons with a positive charge, electrons with a negative charge, and neutrons, which are electrically neutral. In antimatter, there are anti-protons with a negative charge, anti-electrons (also know as "positrons") with a positive charge, and anti-neutrons (which are also neutral, but differ from the normal neutron in some other property). When matter (for example a proton) meets antimatter (for example, an anti-proton), both get destroyed - they convert to pure radiation, i.e., gamma rays. It is not currently known why there is apparently more matter than antimatter in the Universe, although it is believed that the symmetry between matter and antimatter is an almost-symmetry - i.e., the symmetry is not perfect.
Just the same as if normal matter falls in. The matter or antimatter will stay there, increasing the mass of the black hole (and making it more "hungry", i.e., making its gravity stronger).
