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?

Is antimatter greater than infinity?

Antimatter is a substance, while infinity is a representation of a never ending number. They are two separate things, and thus they cannot be compared.


What is the mathematical proof of gravitation force between antimatter to antimatter and matter to antimatter?

Sir Issac Newton proposed the law of gravitational force between mass to mass of matter. That is the gravitational force between to masses is directly proportional to the product of masses and inversely proportional to the square of distance between the two. F=G* m1*m2/r2. Here the F is the force of gravity. G is gravitational constant. m1 is mass one. m2 is mass 2. r is the distance between the masses. Now for the two masses of antimatter you have to denote the negative sign to the mass. So the formula is F = G* minus m1 * minus m2 / r2. So here the F is positive number. So there will be force of attraction between the two masses of antimatter. Hence proved.Now you take one mass of matter and another mass of antimatter. The formula is F = G * m1* minus m2 / r2. Here the F is negative number. So there is no force of attraction between the two. Instead there is force of repulsion. So the force of repulsion between the mass of matter and mass of antimatter is directly proportional to the product of masses of matter and antimatter and inversely proportional to the square of distance between the two. Hence proved.So above is the mathematical proof of the gravitational force between the masses of antimatter and antimatter and gravitational force between the masses of antimatter and matter.


What is the role of gravitational force between matter and antimatter?

The gravitational force between matter and antimatter follows the same principles as between matter and matter. Gravity attracts all objects with mass toward each other. Matter and antimatter would attract each other gravitationally just like matter attracts matter, following Newton's law of universal gravitation.

Where can you find antimatter?

Antimatter can be found in small quantities on Earth in particle accelerators and in outer space, such as in cosmic rays and near black holes. It is a rare substance that is difficult to produce and store due to its volatile nature.

Is dark matter related to antimatter in any way?

Dark matter and antimatter are two separate entities. Dark matter is a mysterious form of matter that does not interact with light, while antimatter is composed of antiparticles that have the opposite charge of normal particles. There is currently no known direct relationship between dark matter and antimatter.
