That's not how it works. According to Einstein's theory of relativity, the energy an object has due to its motion will increase it's mass because matter and energy are the same thing and can become one another. Because of this, if any matter were to reach the speed of light(186,000 miles per second), the energy needed to maintain that speed would reach infinity and it's mass would do the same. Therefore, matter can not and never will be able to reach the speed of light. Also, there's no such thing as a light barrier.
