Proton Torpedoes
Speaking of the Death Star, the very thing that took them down was a proton torpedo blast into a specific opening that we’d later found out was purposely put there as a weakness by the builder. Proton torpedoes supposedly operate like an explosive warhead that releases high-energy proton particles. You might be surprised to find out that we actually do use proton torpedoes, well, sort of. We use protons ultimately.
For over 40 years, we’ve been using them to fight cancer. Proton beams are capable of penetrating human tissue for a specified distance, all according to the amount of energy used. You can focus this proton energy in a specific area, allowing surgeons to remove tumors while sparing healthy tissue at the same time. Effectively removing the cancerous tumor without leaving cancer cells behind. More precise equipment is still being made to further perfect proton use in cancer treatment too!
