Answer:
Antimatter is a material composed of so-called antiparticles. ... But its antiparticle, called a positron, has the same mass but a positive charge. When a particle and its antiparticle meet, they annihilate each other – disappearing in a burst of light.
What is anti-matter?
• antimatter is molecules formed by atoms consisting of antiprotons, antineutrons, and positrons. Stable antimatter does not appear to exist in our universe.
• In modern physics, antimatter is defined as matter that is composed of the antiparticles of the corresponding particles of "ordinary" matter

What is antimatter used for?
Antimatter is used in medicine. PET (positron emission tomography) uses positrons to produce high-resolution images of the body. Positron-emitting radioactive isotopes (like the ones found in bananas) are attached to chemical substances such as glucose that are used naturally by the body.
What exactly is antimatter?
Antimatter is a material composed of so-called antiparticles. It is believed that every particle we know of has an antimatter companion that is virtually identical to itself, but with the opposite charge. For example, an electron has a negative charge
Do we have antimatter?
For the past 50 years and more, laboratories like CERN have routinely produced antiparticles, and in 1995 CERN became the first laboratory to create anti-atoms artificially. But no one has ever produced antimatter without also obtaining the corresponding matter particles.
Can antimatter K1LL you?
Whereas nuclear weapons are 'fail-safe', antimatter weapons are inherently 'fail-deadly': In an antimatter weapon, any failure of containment would immediately result in annihilation, which would damage or destroy the containment system and lead to the release of all of the antimatter material, causing the weapon to...
