# Antimatter

By Parker Ruth
“Antimatter is a weird topsy-turvy shadow of matter, like tweedledum to our tweedledee, where left becomes right and positive turns into negative.” When I first read these words from Frank Close’s book​ Antimatter, I was captivated by the idea that science can be just as mind bending as science fiction — only real

• Why is it that the electron and positron, though differing only in charge, annihilate each other instead of forming a neutral particle?
• You are true. But remember that E=Mc^2 and energy that is created is neutral just as
+1 + (-1) equals 0. In the same way, they form energy and energy and matter are same. Hence your neutral particle and the annihilation which causes the energy is the same.
• Uh, don't both an anti neutron and a neutron have the same charge(neutral)? Why do they still annihilate each other?
• Originally, antimatter was defined as matter with an opposite charge but otherwise the same particle, as described in this video.

However, antimatter is matter with an opposite property, not limited to charge, but otherwise the same particle. An antineutron has the same mass and all other properties of a neutron except for a Baryon Number, which is another property of particles. The neutron has +1 baryon number, while the antineutron has a -1 baryon number.

• How do we know we're not in an antimatter universe?
• We are in an anti mater universe. This universe has both, mater and anti mater. And if you look at things from the perspective of the anti mater, we are the "anti" of them. Course this goes back to relativity.
• According to scienctists, equal antimatter and matter would be created in the big bang, so why didn't they destroy each other?
• The individual particles did not have the same momentum vectors. Granted, the wholes of mater and anti mater were equal and opposite, just the individuals were not, so they did not cancel each other out right away. In other words, they did not come in contact with one another.

• How would one create antimatter? Or is it just there and unable to be made?
• Anti matter can be created with the help of large hadron collider other wise in nuclear chemistry you might have read about positron emission like
C 14------->N 14 + positron. There are even more methods but simplest method is radio active decay
• What is a negatively charged proton called?
• An anti-proton
