Suppose I'd like to take a trip to a Alpha Centauri, about 25.8 trillion miles northeast of Birdseye, Indiana. Assume I have controlled fusion reactors and access to all resources found on the Earth.
What is the fastest I can get there, using current technology and technology likely to appear in the next 10 years? (My fragile body cannot handle unlimited acceleration, and I'd like to stop there for lunch.)
How much fuel will be required? (Don't forget about food, water, and air.)
This is not homework. I'm just curious.
