What If We Traveled Faster Than Light ?

If a man really can travel faster than a speeding bullet.chasing down a projectile fired from a weapon, if it moves by half the speed of the bullet, the rate of removal of the bullet will be halved. If you already travel faster than the bullet, you will overcome them and lead the way. Here we will use Newton's views of time and space: that the positions and movements of objects in space must be measured in accordance with the absolute and inert frame of reference.

In the early 1900s, scientists held firm to the Newtonian view of the world. Then a German-born mathematician and physicist by the name of Albert Einstein came along and changed everything. In 1905, Einstein published his theory of special relativity, which put forth a startling idea: There is no preferred frame of reference. Everything, even time, is relative. Two important principals underpinned his theory. The first stated that the same laws of physics apply equally in all constantly moving frames of reference. The second said that the speed of light - about 186,000 miles per second (300,000 kilometers per second) - is constant and independent of the observer's motion or the source of light. According to Einstein, if the human were to chase a light beam at half the speed of light, the beam would continue to move away from him at exactly the same speed.

These concepts seem deceivingly simple, but they have some mind-bending implications. One of the largest is represented by Einstein's famous equation, E = mc², where E is energy, m is mass and c is the speed of light. According to this equation, mass and energy are the same physical entity and can be changed into each other. Because of this equivalence, the energy an object has due to its motion will increase its mass. This only becomes noticeable when an object moves really quickly. If it moves at 10 percent the speed of light, for example, its mass will only be 0.5 percent more than normal. But if it moves at 90 percent the speed of light, its mass will double.

As an object approaches the speed of light, its mass rises precipitously. If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.
