How do you stay alive, where are you headed, and would your spacecraft last that long? Also the faster you go, your radiation exposure will increase.

The argument that, if intelligent life did exist in the universe, it would already be here -- is akin to the time travel argument, that if time travel did indeed exist, time travelers would also be among us. This takes us back to the space time continuum, and tends to make the case that time and distance, although relative, have irrefutable laws that cannot be bent or breached to cause Earthlings to venture into the void, and conversely keeps venturers from the void from Earth.

Time-line studies show that every time a level I civilization perfects a device that scientists agree may be capable of going where no man has gone before, someone starts a war. The price of gasoline goes up, and the costs associated with the program skyrocket. Congress cuts the funding and the project languishes on the drawing board -- until the cycle is repeated. This process goes on for billions of years.
