I have been reading for my physics class a section of a book about relativity. Relativity mostly deals with objects in time and space as they approach speeds close to the speed of light, or c. Einstein created two postulates of relativity coming to the conclusion that nothing can ever travel as fast as or faster than the speed of light. When objects travel through space at speeds close to c they experience what it referred to as time and space dilation. As an object moves faster, due to relativity, the object becomes shorter, length contracts. As strange as this might seem time dilation is much stranger. As an object moves faster it experiences time differently. The faster an object moves the slower time is for that object. For example, if you get on a rocket ship traveling close to the speed of light, and fly around the earth for ten years, then land. When you land, you will feel as if you have been gone for ten years, while in actuality, according to time on earth, you will have been gone for hundreds of years.
This was a very hard concept for many people to grasp. Relativity presents that as you move faster, length and time get shorter and longer respectively. According to this theory no object can go as fast as or faster than the speed of light. Relativity goes as one over the factor square root of one minus v squared divided by c squared, where v is the objects velocity and c is the speed of light. I started thinking of what would happen if you accelerated an object to the speed of light. According to relativity, the objects length would shrink to zero and it would experience time as infinite. So, if a person were to travel at the speed of light that person would disappear and time for them would last forever. Theoretically this sounds like a scientific heaven of sorts. What if we could somehow travel the speed of light, would we reach another place where time would be infinite and we would last forever? Is it possible that this sacred place exists? There is no way to know for sure. I just thought that was something interesting to think about that I came across while reading.
