Fast Facts:
- Its existance was first postulated in 1928 by Paul Dirac
- One gram has enough potential energy to drive a car for 100,000 years without stopping
- Most expensive substance on Earth, produced at about 62.5 trillion dollars per gram
- Less than 0.16 grams of antimatter are produced every year on Earth laboratories
- Unequal distribution of matter and antimatter in our known Universe is one of the greatest unsolved problems in physics
- Practically applied to medical imaging in the positron emission tomography technique
