Here's why:
* Newton's laws are universal: They are fundamental laws of physics that apply to all objects with mass, regardless of their location.
* No friction in space: While there's no air resistance in space, the laws of motion still hold. Objects in space will continue moving at a constant velocity unless acted upon by a force, just as described by Newton's First Law.
* Gravity still exists: Newton's law of universal gravitation describes how objects attract each other due to their mass. This force is present in space, although it's weaker than on Earth.
However, it's important to note that in extreme conditions like near black holes or at very high speeds, Einstein's theory of relativity becomes more accurate. But for most scenarios in outer space, Newton's laws provide an excellent approximation.
