Antimatter has been proven to exist, but it doesn't last too long, since there's a lot of matter in the universe which would annihilate them as will be explained below.
Antimatter consists of subatomic particles like electrons and protons that have the opposite charge of a regular proton or electron. They're also referred to as positrons and negative protons.
The only real use for antimatter would be for fuelling energy conversion and creation. When a particle of antimatter collides with a particle of normal matter such as an electron colliding with a positron they'll be converted into pure energy.
This type of energy conversion is the best we can possibly get as with most mass to energy conversions we only get a small fraction of the mass converted into pure energy. To get an idea of the energy conversion of a small amount of matter, use Einstein's famous equation of E=mc^2.
Energy is equal to mass times the speed of light squared. For 1 gram of matter converted into pure energy it would be about the energy released by a ~21 megaton explosion of TNT. So to be able to harness this amount of energy we would never have any problems with energy again.
The only problem is being able to sucessfully harness that much energy and to be able to produce enough antimatter to keep it going and also to contain the antimatter so it doesn't mix with normal matter, if it did...well you can guess at the results....

Antiparticles are particles associated with most massive particles that have the same mass but opposite charge. So a proton has positive charge while its antiparticle, an antiproton, has negative but the same mass.
Antiparticles are created in high energy particle collisions, such as those in particle accelerators. They can form atoms in principle (hence antimatter), but this is exceedingly rare (and only anti hydrogen has been observed) and they are short lived.
There is no practical use for antimatter.

antimatter exists yet has no play within daily life because of newtons second law f=ma, quantum mechanics conflicts with our basic desire of everyday life. if you throw an object technically its antimatter is free form meaning it follows the matter because it has NO matter lol... but seriously if nothing has matter within a volume it has no Force. which serves as no purpose to everyday life other than just knowing its there. antimatter is composed of antiparticles so if you have no matter with matter then they collide theoretically they will cancel one another out. But its used in TNT, formation of water, and can help with nuclear fission. (like you use these in everyday life; hey ma i'ma go blow up the yard let me see if i can measure its antimatter before i explode) this shows cancelation of matter. if nothing has matter it has no mass, so then probability of quantum mechanics takes over and newtons laws, (physicists say) do not apply. but that's balogna if classical mechanics still are used today to determine Force of objects with a mass of 68kg traveling at a speed of 20m/s....... so you choose lol.......

Yes, it exists, but not for very long in our universe. It can be seen and measured in cloud chambers. As soon as it touches a piece of positive matter, it is destroyed. Basically it is an opposite atom, one with a negative proton and a positive electron. A number of people have suggested it is a particle moving backwards in time, but that is just theory. If it could be collected and isolated, it could be a great way to store massive amounts of energy for deep space voyages.

Yes, but scientists dont really know what it is. basically all matter including antimatter is made up of the same basic substance.

Antimatter is nothing more than a "theory"

as the name implies, it is against matter. when it gains contact with matter, they cancel out. it's like the negative of matter like in Math. it does really exist.
