I'm writing my own little book, and in it I have two characters fighting. One of them uses a big ass laser to vaporize the other. my question is, how much energy/heat would it have to produce to burn a hole through the Earth, and would it affect Earth in any other way outside of, well the big ass hole? Lastly, how big does that hole have to be for it to destroy the Earth? Would a hole the width of football be sufficient?
