in einstein's special theory of relativity, there is one basic principle [or assumption, or law] that seems very odd to our intuitions, and that is responsible for the odd nature of einstein's conclusions. this basic principle is

The basic principle in einstein's special theory of relativity is The idea that light has the same speed for all non-accelerated observers.The unique concept of relativity is founded on fundamental concepts: that the laws of physics need to be impartial to the uniform movement of an inertial frame of reference, and that the velocity of mild has to have the same regular cost in the sort of frame. The theory of relativity are the same in all inertial frames of reference. It follows that: Absolute motion can not be seen in any law of physics. All experiments run equally in all inertial frames of reference.The legal guidelines of physics are identical for any inertial reference frame. 2. The principle of the speed of light: the velocity of light in a vacuum is the same for all observers, regardless of their relative motion or the motion of the supply of the mild.Learn more about the theory of relativity here:-https://brainly.com/question/364776#SPJ4
