|Is interstellar space travel possible?|
Well, after reading Carl Sagan's "Cosmos", I believe it is possible.
Carl Sagan's "Cosmos" Page 152:
"If we lived in an interstellar spacecraft that could accelerate at 1 g, we would find ourselves in a perfectly natural environment. In fact, the equivalence between gravitational forces and the forces we would feel in an accelerating spaceship is a major feature of Einstein’s later general theory of relativity. With a continuous 1 g acceleration, after one year in space we would be traveling very close to the speed of light [(0.01 km/sec2) x (3 x 107 sec) = 3 x 105 km/sec]."
But, where can you get the energy to push a spaceship at 1 g acceleration for one whole year? The answer is, nuclear energy, whether it is deuterium+tritium or uranium.
