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".
The amount of planet matter equal to that of the astronaut would annihilate.
Dark matter is matter of an unknown type. It is known to exist, due to its gravitational influence, but it is not known what it is made of. There is at least 5 times as much dark matter than "normal" matter.
Basically, the process involves creating a concentrated release of energy from the collision of atomic particles with atomic nuclei, such that "pair production" occurs: 1 particle of matter and 1 particle of antimatter. It is possible to contain antimatter (positrons, anti-protons) within a magnetic field. Some of the links below may be helfpul. As you'll note, it takes some pretty sophisticated equipment, and not a lot of it has been made.
About 5% of our Universe consists of baryonic matter; ie, stuff we fully understand. Our Universe also contains about four times more mass in some form we DON'T understand, and that's why we call it "dark matter." And about 75% of the energy of the Universe consists of something that is causing the rate of expansion of our Universe to speed up. It can't be something with mass, because mass would cause the rate of expansion to slow down. So it has be some form of energy we just don't understand -- so, for now, we simply call it "dark energy." These two entities have nothing whatsoever in common other than the first word in the description we humans have given to them.

The reason we live in a universe made mostly of matter rather than antimatter is still a topic of active research in physics. One leading theory suggests that there was initially a slight imbalance in the production of matter and antimatter in the early universe, leading to the domination of matter. This imbalance is known as baryon asymmetry. Experiments are ongoing to understand this asymmetry and why it occurred.
antimatter and dark matter
Yes. Antimatter is only a point of view concept : we can imagine any object made of what we call antimatter. According to his point of view, we would be made of antimatter. Moreover, a number of large areas of the universe, that doesn't have any contact with each other, may be made of antimatter. we wouldn't have any mean to know from where we are.
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.
Some concepts like thoughts, emotions, and ideas are considered not to be made of matter as they are abstract constructs. In addition, forces like gravity and electromagnetic fields are also non-material entities that exist in the universe.
Antimatter looks identical to regular matter, as both are made up of particles like protons, electrons, and neutrons. The main difference is that antimatter particles have the opposite charge of their corresponding matter particles. When antimatter and matter come into contact, they annihilate each other, releasing energy in the form of gamma rays.
Yes, antimatter is real. It is made up of particles with the same mass as normal matter particles but with opposite charge. When matter and antimatter come into contact, they annihilate each other, releasing a large amount of energy.
Sir Issac Newton had three laws of motion, which all concerned matter. The first was the law of inertia: an object is either still or moving at a constant speed, and will stay either moving or at the same speed unless acted on by an external force (such as friction - this is why you cannot slide forever on concrete). The second was the law of force: F=m*a (where F=force, M=mass, and a=acceleration). The third was the law of conservation of energy: for every action, there is an equal and opposite reaction (this is why, if you push off of the floor with your feet, you will go up - commonly known as jumping).
Oh, of course, my friend! Dark matter is this mysterious substance in space that we can't see directly, but we know is there from its gravitational effects. Antimatter, on the other hand, is kind of like the mirror image of matter, with particles that have opposite charges. Both are fascinating aspects of the universe that scientists are still learning about every day. Keep exploring, keep asking questions, and it's all part of the joyful journey of understanding the world around us.
A molecule. But all the compounds ans elements in the universe are made from atoms. (and possible from antiatoms in the undiscovered now antimatter).
Since anti-methane is made of antimatter, its opposite would be methane, the compound made of normal matter.
No, a black hole is not made of antimatter. A black hole is formed when a massive star collapses under its own gravity to a point of infinite density, known as a singularity. Antimatter is composed of particles with properties opposite to those of normal matter, such as having opposite electric charge.
