Accordingly with the current understanding of physics the Universe has a speed limit and it seems there is no way around it. It makes a lot of sense with one condition: we still don't know everything about the universe. I don't challenge Albert Einstein's work, I can't do it because I am a software engineer not a physicist, I only have a different interpretation of the theory of the relativity: the space is curving around us in a little different way. Having a mass is curving space but in such a small degree we don't see it. Having a huge mass (like Earth, for example) will curve the space in a bigger way, it's something we call gravity. If we don't stand we'll fall because of it.
Having a mass AND a huge speed will curve the space around you. Light have the greatest known speed because it's just another wave (just like any other magnetic wave) with no mass so not such limitation. When the mass and the energy are combined the object also curves the space, that's why its time runs slower and its mass seems to increase when measured from an exterior perspective. The worm holes are the sonic boom applied to space itself, and the bigger effect are the black holes.
