Title: वैकल्पिक

Text: That light travels at speed c in all directions is a consequence of the laws of classical electromagnetism, and special relativity grew out of the realization that the speed of light c is the same in all inertial frames. These two observations suggest that classical electrodynamics might already be consistent with the principles of relativity. प्रत्येक पराग्राफले परीक्षण हुनेछ।
