Let's start a fresh topic today. The Special Relativity or The Special Theory of Relativity published by Albert Einstein in 1905.
An important postulate from that theory is that the speed of light in vacuum as measured by an observer irrespective to its state of motion remains the same and equal to 'c'. What does this mean? Are we contradicting the laws of physics made by the great Sir Isaac Newton?
Probably, yes. Einstein said that the laws of physics are applicable to speeds very low respective to the speed of light. At greater fractions of the speed of light, the laws of physics proposed by Newton are inapplicable and hence a new theory was introduced. It was probably because of Maxwell's Electromagnetic field equations, that Einstein proposed light to be an electromagnetic wave and that it doesn't necessarily require a material medium to propogate.
What happens that we observe the speed of light to be the same? This once again takes us back to the slow down of time. As the time slows down at higher speeds, by a fraction described earlier, the measured speed of the light by the simplest equation(v=d/t) is observed the same. Time and light both travel as any other object in the universe. The finiteness of the speed of light actually is the main reason about the slow down of time.
The nature of spacetime is curved near massive objects. Spacetime is influenced by mass and energy. So, time bends or slows down instead. Many other theories have been proposed by Einstien such as relativistic mass, length contraction and other such anomalies. But they are pretty special and proven experimentally in their own ways.
No question about, arguably, the greatest scientist of all time and my personal favorite too!
