I need help building a microwave large and powerful enough to microwave the entire universe. Ideally it should destroy itself through the microwave process, because once the universe is cooked we cant have a huge microwave sitting around in nothingness. I have an unlimited budget for this project, and require scientific knowledge to help design and build this microwave. I don't want to end up microwaving the universe, so don't worry too much, I only want the ability to do so if necessary, before someone else does.
