Sorry to get back to you so late Drakkith, but I'm not yet too familiar with how this forum is laid out and I'm actually quite lost.Drakkith said:Hi Orien. Can you post a link to the thread in question?
Light speed is the speed at which light travels in a vacuum, which is approximately 300,000 kilometers per second. It is measured using a unit called the speed of light, denoted by the symbol c.
According to Einstein's theory of relativity, it is not possible for anything to travel faster than light. As an object approaches the speed of light, its mass increases infinitely and would require an infinite amount of energy to continue accelerating.
As an object approaches the speed of light, time slows down for the object relative to a stationary observer. This is known as time dilation. Additionally, space appears to contract in the direction of motion, known as length contraction. These effects are a result of the constant speed of light being the same for all observers.
No, we cannot observe light traveling at the speed of light. This is because as soon as light is emitted, it is already traveling at its maximum speed. We can only observe the effects of light, such as seeing objects due to the reflection of light off of them.
Understanding light speed is crucial in the fields of physics and astronomy. It helps us understand the fundamental laws of the universe and how objects behave at high speeds. It also has practical applications in technologies such as GPS and satellite communication, which rely on precise timing and the speed of light to function accurately.
