View the next article here - Subatomic Particles - Introduction ----------------------------------------- Most of us have come across the word - matter. Matter is found all around us. Our universe is formed from matter. Matter is formed of atoms that have particles called electrons which are negatively charged. Then what is antimatter? Let us return to 1928 when Paul Dirac gave a brand new and stylish equation to explain how particles like electrons behave after they travel near the speed of light. He found that the equation had two solutions (just like how x^2 = 2 has two solutions: x=2 and x= -2) - one for an electron with a negative charge and the other for an electron with a positive charge. The matter that we see around is created of atoms that have negatively charged electrons. So, Dirac dismissed the 2nd solution i.e. of positively c...
