CT is a kind of antimatter, and it can also be said to be an inverted form of matter.For the earth, CT is strange, but there are many meteors, comets and asteroids formed by it in space. CT atoms consist of a negatively charged nucleus and positively charged electrons.This is a difference that cannot be seen by the naked eye, but it is also a fatal difference. CT matter looks just like normal matter—as long as the two don't come into contact.Once the contact occurs, the opposite electric lines of the two substances cancel each other out, and the opposite particles explode, releasing huge energy.This ratio of energy release is demonstrated by the famous Einstein equation.This sweeping response makes fission seem as insignificant as lighting a safety match.However, there are still those who want to contain this immense energy.Space engineers like Brian and Drake dream of building CT machines to mine and smelt CT ore for building CT power stations.They are all big fools. CT is untouchable. In theory, it is impossible to successfully develop a safe chassis for CT tools with a base made of materials.Only one thing is certain, CT meteor swarms pose a great threat to interstellar travel.
