# Space-Time: Does it Follow Newton's Third Law?

• B
In summary, Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. This law applies to all forces in the universe, including those in space-time. While it generally holds true, there are some exceptions such as extreme conditions near a black hole. Einstein's theory of relativity also affects the way forces and motion behave in space-time, but in most cases, Newton's Third Law can still be used accurately.
Do space-time have such behavior that if we give force on it and eventually it reacts according to the third law of Newton?

No. Spacetime is not something to which you can apply forces, so far as we are aware.

## 1. What is Newton's Third Law of Motion?

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. This means that when an object exerts a force on another object, the second object will exert an equal force in the opposite direction.

## 2. How does Newton's Third Law relate to space-time?

Newton's Third Law applies to all forces in the universe, including those that act on objects in space-time. This means that for every force that acts on an object in space-time, there is an equal and opposite force acting on another object.

## 3. Does space-time follow Newton's Third Law?

Yes, space-time follows Newton's Third Law. This is because space-time is affected by forces, such as gravity, which obey Newton's laws of motion.

## 4. Are there any exceptions to Newton's Third Law in space-time?

While Newton's Third Law is generally applicable in space-time, there are certain situations where it may not hold true. For example, in extreme conditions such as near the event horizon of a black hole, the laws of physics may behave differently and Newton's Third Law may not apply.

## 5. How does Einstein's theory of relativity affect Newton's Third Law in space-time?

Einstein's theory of relativity states that space and time are not absolute, but are instead intertwined and affected by the presence of mass and energy. This means that the way forces and motion behave in space-time is not exactly the same as what Newton's laws describe. However, in most cases, the effects of relativity are negligible and Newton's Third Law can still be used to accurately describe motion in space-time.
