Annihilation of matter (such as electrons) and anti-matter (such as positrons) occurs with such a high degree of reliability, the consistency invokes a sense of precision inherent with the most accurate time piece. Moreover, such consistency ratchets up the applicability factor associated with PET scans. However, this same reliability as well as applicability (and the very same exacting precision) serves as the Achilles’ heel of the Big Bang theory because matter/anti-matter annihilation interactions raise questions concerning the origin of matter in the universe.
Where does ordinary matter come from?
According to the Big Bang theory, matter and anti-matter arose at the same time. Nevertheless, neither a surplus in matter nor a deficit of it are detected from anti-matter and matter collisions performed experimentally (that is, from experiments thought to mimic conditions associated with the Big Bang). And this fact leaves us with an important question: where did all of our plain, ordinary matter existing abundantly around us come from? You can help answer this question by taking part in our creation science writing contest, by choosing the question that deals with PET scans in medicine.
The technique of PET imaging
And who knows, maybe a career path too
Nuclear Medicine Technologists are the professionals responsible for implementing PET scans for the physicians who order these tests. So, who knows, from the knowledge gained through contest participation, you could be taking the first steps toward an exciting, patient-focused career. We look forward to reading your entry!
