Albert Einstein's theory of general relativity states that as something approaches speed of light, time itself slows. Light obviously travels at speed of light. How can we say we accurately know its speed when we don't account for relativity? Is it not possible light travels far faster or possibly slower than we assume, but because it is on another plane of time, its apparent speed is incorrectly calculated based on the assumption that the time of light and the time of where it moves to and from are the same?|||When we came up with the speed of light, we compared it to our frame of view. Remember the Earth is moving at hundreds of thousands of miles per hour around the sun, so we are to. On a planet moving slowly, light would travel faster. The speed of light is relevant to us.
To be accurate, when scientists measure the speed of light, they do so in space. The first accurate measurement was taken by observing the moons of Jupiter, so Earth's movement didn't matter. (The mathematics accounted for planetary motion)
In short, we measured the speed of light in relation to stationary points. You can't use a as a reference point for the speed of light. It's like running at 5 mi/hr and saying you're moving at 3 mi/hr because you're comparing your speed not to the Earth, but to someone else running 2 mi/hr.|||Because we don't have to be going as fast as light to measure it. Just measure how long it takes to get from one place to another.|||it's measured indirectly:|||We can both measure its speed very accurately as well as determine it indirectly in other ways. For example, 2 highly accurate clocks separated by a distance and some simple electronics is about all it takes. In fact, the problem is getting any OTHER value for the speed of light, since even mass, time and distance will bend in order for the speed of light to remain a constant. Thousands, and I do mean THOUSANDS of experiments have verified this since Einstein announced it.|||O.K. this is a once in a lifetime answer. We exist within the perameters of our dimension as percieved by our normal senses. (Einstein also said that we live in the third dim. time is the fourth and God is the fifth). And it is also said that he would uncontrollably shiver when he referred to this Idea. That would be known as spiritual confirmation. As a mortal we can only percieve motion to the extreme of 186,000 mps. As a spirit we can experience superluminous speeds, which would be spontaneous between A and B no matter what the distance between the two points. There is a difference between speed and velocity. You are a spirit living in a earthen vessel, that earthen vessel can reach a speed that can destroy it unless it is protected within something else travelling the same speed. Your spirit can travel spontaneously from any point in time/space to any other existing point in time/space. There is a diminishing fine line between science and theological understanding, that is becoming thinner with the advancement of technology. God is timeless, when we are released from these perameters of existance in which our spirits are contained for the duration of this learning experience, (life). Then we shall exist in the dimension where God is. To be Holy is to be in the presence of God, whether that be here and now or in the hereafter. Think of life and perception (consciousness) as being in phases, 1energy2mass3space4time5God and the perception of all these is totally relevant to the existance of Consciousness and you shall understand the answer to the next question when you "exceed the speed of light". James Mark Platt.|||Actually, you're talking about the special theory of relativity. The general theory states that mass warps space, which is what we experience as gravity.
And interestingly enough, the cornerstone of the special theory of relativity is that the speed of light is the same ALWAYS; no matter what speed you're going; no matter what you're counting your speed relative to.
If you and a friend are in spaceships going at 95% the speed of light, if the ship in the back shines a light at the one in front, you would measure the light coming from it to you at the same speed as when you measured the light from the front ship going towards the back. If the two ships sped past a planet which intercepted the light being beamed between the ships, it too would measure the same speed of light being emitted between the ships, as well as from other "stationary" sources nearby.|||http://www.youtube.com/watch?v=V7vpw4AH8鈥?/a> this explains.
