Parallel Universes and a speed faster than light (Multi-part question/Michio Kaku)?

you can not push the speed of light. Although there is a theory about UFOs that they have an element that is super dense known as element 115. This is a very scifi theory but may be true and may work. The atoms in element are so dense that it bends space and time as we know it. Einsteins theory says that any m can not travel faster than the speed of light. With this super dense element if it is out there... will allow us to actually have a m of 0 and travel as fast as the speed of light and even faster. This is not proved though.
