1 positioned differently will describe the same event differently. Both may be true to
the extent of their individual observations, at the samte time, they are false relative
to each other. Now, readers can realize how close the theory of relativity is to the 1 principle of Syadwad?
Light a Unique Substance
(For reasons of ease in understanding, we may treat all waves traveling at a speed or 3x108 m/s as light)
• Light has the fastest speed known to us so far. No matter can travel faster than light. As a particle approaches speed of light, three things happen
- Its volume shrinks to zoro. - Its mass become infinity. - Time is rendered void.
In other words only mass-less particles(!) can travel at the speed of light. This condition is defined by the following equation of Einstein
No law of physics remains valid at the speeds greater than that of light - mass, volume, time all will assume negative or imaginary values in such a case.
• Light comprises of mass-less 'packets (quanta)' of energy called photons. Some scientists also call them as mass-less 'particles' because, light is observed to travel like a wave, and also interact like a particle. This duality is called principle of uncertainty in scientific terminology.
Light is therefore a boundary between existence and nothingness. Light is the substance which carries and transact the whole information. But, light itself is uncertain in its behaviour!
