Action/reaction : if we do an action that requires energy of the whole universe

  1. Sep 15, 2007 #1
    what would the reaction to it be? Just suddenly has this question popped up in my mind.

    Does this mean the universe would transform into something else through the reaction? Because after all energy cannont be created or destroyed. Maybe a new big bang?

    Newton's 3rd law?

    Action/reaction refers to force pairs in Newton's 3rd law: If object A exerts a force on object B, object B exerts an equal and opposite force on object A. If "object A" is the entire universe, what could possibly be "object B"? Perhaps you can restate your question.
