WebMay 15, 2024 · Alternative method, no Lorentz transformations required. The spacetime interval measured by $$ (\Delta \tau)^2 = (\Delta t)^2 - (\Delta r)^2\, ,$$ is something that all observers in all inertial frames of reference agree on. In this case, $\Delta \tau$, the proper time measured on the travellers watch is 1 year. On the Earth, the change in position is … Webspecial relativity; it is not the actual speed of light, but the ratio between the minimum length and the shortest time of discrete space and time. Section 4 further discusses this argument, which suggests a more complete theory of relativity without light, the theory of relativity in discrete spacetime.

WebMar 10, 2024 · Moving at the Speed of Light. One of the key insights that Albert Einstein used to develop his theory of relativity was that light in a vacuum always moves at the same speed. The particles of light, or photons, therefore move at the speed of light. This is the only speed at which photons can move. They can't ever speed up or slow down. brahmin blue topaz

WebDec 21, 2024 · Einstein's assumption that the speed of light is constant is a fundamental principle of modern physics with great influence. However, the nature of the principle of constant speed of light is rarely described in detail in the relevant literatures, which leads to a deep misunderstanding among some readers of special relativity.
