Although many propulsion systems have been theorized with differing pros and cons, there is one theorectical way to avoid the entire issue. While it is impossible to travel at faster than light speeds, it is possible to distort space and time. However, in order to make these distortions, huge amounts of energy and mass would be needed.

Wormholes for Dummies

1. Take a huge amount of Super Dense matter (at any near Neutron Star) enough to construct a ring the size of the Earth’s orbit around the Sun.

2. Then build another ring where you want the other end of your wormhole.

3. Next, just charge up both rings to an incredible voltage, and spin them up to near the speed of light.

These points will then create space-time distortions and allow you travel from one place in the Universe to another.

Unfortunately, the scope of the mass and energy needed in order to create such distortions make the concept of wormhole creation completely confined to hypothesis.

An important lesson in Special Relativity is the importance of limitations. As energy is added to a moving object it moves faster, but this reaches an assymptotal barrier at the speed of light.

The atoms and molecules that make up matter are connected by electromagnetic fields, the same stuff that light is made of. In the case of the light speed barrier, the thing that’s trying to break the barrier is made up of the same stuff as the barrier itself. How can an object travel faster than that which links its atoms?

While traveling faster than the speed of light is not allowed, it is unknown how fast spacetime can move itself.

"To use an analogy, imagine you are on one of those moving sidewalks that can be found in some airports. The Alcubierre warp drive is like one of those moving sidewalks. Although there may be a limit to how fast one can walk across the floor (analogous to the light speed limit), what about if you are on a moving section of floor that moves faster than you can walk (analogous to a moving section of spacetime)?"

The Alcubierre's "Warp Drive" concept theorizes moving a section of spacetime by expanding spacetime behind the ship and by contracting spactime in front of the ship. Unfortunately this theory assumes a much higher technological advancement. In order to achieve this, a ship would need to be wrapped in large amounts of "negative energy," which would allow it manipulate space time. However, it is still debated in physics whether "negative energy" exists.
