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

PLAIN] [Broken]In summary, the conversation discusses the concept of action/reaction and how it relates to Newton's 3rd law and the potential transformation of the universe. The question of whether the universe could transform through a reaction and the possibility of a new big bang is also brought up. The mention of Mach's principle as a potential explanation is mentioned as well.

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.

1. What is the concept of action and reaction in science?

The concept of action and reaction is based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object will exert an equal and opposite force back on the first object.

2. How does an action that requires energy of the whole universe work?

An action that requires energy of the whole universe means that the force exerted by one object will be felt by all other objects in the universe. This is because the force of an action is not limited to just the two objects involved, but it affects the entire universe.

3. Can an action that requires energy of the whole universe be observed in everyday life?

Yes, there are many examples of actions that require energy of the whole universe in everyday life. For instance, when you walk, you are exerting a force on the ground, and the ground is exerting an equal and opposite force back on you. This action and reaction is happening between all objects in the universe, but the effects may not be noticeable on a large scale.

4. How does the energy of the whole universe affect the action and reaction?

The energy of the whole universe does not affect the action and reaction itself, but it is a result of the action and reaction. When an action is performed, energy is transferred and transformed between objects, and this energy is felt by all objects in the universe due to the interconnectedness of all matter.

5. Is it possible for an action to have a reaction without requiring energy of the whole universe?

No, according to Newton's third law of motion, every action will have an equal and opposite reaction. This means that in order for an action to occur, there must be a reaction, and this reaction will be felt by all objects in the universe, even if the effects are not noticeable on a large scale.
