@KingOfWhiteAmerica @Starprophet1 @Jonny @matty @TrevorGoodchild @catmanmancat @suquili Maybe you have an idea to this theoretical question. 2 objects are approaching each other on a linear trajectory. Both objects have a speed of 0.6 C, so in abstraction we have a stationary object and a moving object approaching with 1.2C. What impuls energy will be created on impact considering that mass becomes lim(infinite) when reaching C.
