What would be more practical for interstellar transportation? Teleportation or Space Travel?

Teleportation requires a device on the receiving end too. You can't just step into a transporter, get dematerialized, then beamed across a vast distance without something on the other end to catch you and put you back together. Besides, the only way teleportation could work at all within the laws of physics is if the person being teleported were completely broken down to the subatomic level at the point of origin and an identical copy was created at the destination. I don't think many people would go for that.
Space travel is slow even at the speed of light. It would take us over 4 years to get to the nearest star besides the Sun, and there are only 8 star systems within a 10 year trip at light speed. Even traveling at light speed is breaking the laws of physics because moving an object with mass at that speed would require an infinite amount of energy.

Both of these are currently impractical at best. The general consensus in physics is that it is theoretically impossible to travel faster than light, and practical limitations limit your speed; it takes several years for anything to reach the edge of the solar system from Earth. However teleportation isn't much of a possibility either; we can teleport photons (light particles) but that wouldn't be good for sending any material item to a place several thousand light years away. However, what it could do is send information in the form of an electrical or light signal almost instantaneously (instead of just 300'000'000km/s). Right now the technology is being put to use to make faster computers but it could allow us to communicate easily with any extraterrestrial species that have perfected the technique. However, I doubt that space travel will completely die. We haven't stopped walking just because we've invented cars.
