Every time a curious audience looks to the cosmos, he travels in time hundreds, thousands, millions, even billions of years. The photons in the mysterious celebrities he/she is looking at have traveled through time in 186,000 miles a second, before his/her eyes caught them. Lighting is the 1 particle which sheds luminosity more than all, and is the only means of viewing the elusive and glorious nature of the world. However, to know lighting is too understand its rate--a pace so great that nothing with mass could ever attain it. So what is the speed of light? It's 299, 792, 458 meters per second or 186,000 miles a second, but people didn't always understand that light was that this speed--at a single point in time people thought that light could travel any distance in no time whatsoever. Later experiments were created to gauge the exact speed, but lets start from the beginning. Among the First questionings of the rate of light has been performed by a Greek Philosopher from the name of Empedocles. Empedocles taught that the universe was composed of fire, air, water, and earth. He also was the first to say that light had a finite speed. He proposed that light was something in movement and had to take time to travel. Aristotle thought that light is a result of the occurrence of something--not any movement. Ptolemy and Euclid, two great mathematicians, spoke about that there new emission theory of vision, which told that light will be emitted in the eye. Heron of Alexandria, an Egyptian mathematician, suggested the rate of light has to be infinite, because of the distant objects emerging right as the opening of eyes occur. Johannes Kepler, the fantastic astronomer of all Germany, stood by the thought that the speed of light was infinite, since empty space has no barrier to it. Without.
