What is antimatter?
Antimatter as the name suggests, is exactly the opposite of normal matter. These particles are mirror image of matter. Antimatter is of the same size as normal matter, but has opposite properties (like electrical charge).
Some of the examples of antimatter particles are
Positron- They are electrons with a positive charge. Discovery of positron in 1932 by Carl Anderson proved that antimatter exists.
Because of this difference between the natures of the two particles, antimatter and matter, they attract each other and upon collision they produce a brilliant flash of light. Due to this collision the entire mass of both the particles is converted into energy. This energy released can be used to propel the spacecrafts.
As we now know what are antimatter particles, let us see the working of antimatter engines
