Hello. I am working on a paper regarding the concept of a lack of free-will, and I am taking the stance that physics could determine fate. I am proposing that all actions (such as brain functions that cause our thoughts and feelings) could be pre-determined through the use of applied physics if all variables in the universe that could alter or change any results are taken into effect. Basically, every brain functions of every life-form, every gravitational interaction, every death of a star, anything that could happen throughout the entire universe could be used as a variable to determine the future. I was looking for PF input on this concept for extra ideas for the paper. Thanks.
