Misled understanding of frame
Before Relativity, the Newtown's hypothesis of ether considered a unique and universal reference frame in which every motion were absolutely referring to.
Because of the Michelson & Morlay's experiment any notion of reference frame has been discarded.

With Newtown's ether, both Buddha A and B are moving in their own frame and they can measure their absolute speed in that universal medium. When Buddha A launches a ball to Buddha B, every observer doesn't consequently measure the same speed for the ball. The absolute speed of the ball is different from the speed in the A frame which is also different from the speed in the B frame. |

When photon has been discovered in the early 20th century, the grained component of the light was looked upon as a material particle, like the Buddha's ball. The same difference of speed was then awaited by physicists. However the famous experiment of Michelson & Morlay hasn't measured any difference of speed. Because of this result, physics has banished up to now any existence of ether.
Relativity has then considered a materialistic approach of phenomena in a pure empty vacuum. In that case any frame, whatever its mass or motion, represents a reference in which every speed can relatively refer. Pursuing its logics, Relativity claimed that the speed of light is a universal constant and thought of the curvature of space-time to explain gravity.

With nowadays official Physics, every references are then equivalent. Both Buddha observe the same speed of light. |
