I did not see any specification on the amount of fuel that the space shuttle orbiter itself could carry, so I used the brown external tank instead. That tank was capable of carrying 106,261 kg of liquid hydrogen, in addition to the liquid oxygen oxidizer. Let's replace the liquid hydrogen with liquid antihydrogen. If we annihilate this liquid antihydrogen, we get a theoretical energy yield of 1.910e+22 joules, which is roughly equivalent to a 4.56 teraton nuclear explosion, which vastly exceeds the power of any nuclear weapon ever designed. Since we want to use this liquid antihydrogen as a fuel and not a bomb, if we react it slowly, it would not only allow us to go to nearby stars, but to accelerate us to a significant percentage of lightspeed.

At least in theory, it could. In practice, there is the huge problem of generating enough antimatter to be useful for anything other than research or PET scans. The problem lies in the fact that to obtain antimatter, we have to use particle collider to make every single antiproton needed, as well as the positron emitting radioisotopes needed to make atoms of antihydrogen. Overall, it is far easier to use something like the Orion nuclear pulse propulsion method to reach Proxima Centauri.

According to a simulation I ran, if one were to replace all the fuel in a traditional rocket with antimatter, everyone inside would die.

 wow... I did not see that coming!!!

@Micheal238 PLEASE DO NOT SAY THINGS IF YOU ARE A DUMMY AT PHYSICS!!!!!

 

A GRAM OF ANTIMATTER WOULD TAKE US TO MARS AND BACK.

 

AND TEH TEMPRATURE DOESN'T MATTER, IT'S THE ENERGY AND PRESSURE. SO READ WIKIPEDIA BEFORE YOU SAY SILLY THINGS, PLEASE.

 WHY ARE YOU TYPING IN CAPS? its giving me a headache on my D.C trip.

By the way it's calcium...

 Well done on your physics knowledge so I'll, know it for next school year.

Isn't Alpha and Proxima Centauri a binary star system?

Also wikipedia has it's major flaws letting people edit there wiki without permission is just plain wrong. I could just say the earth is a star on wikipedia.

 Actually, it appears to be a triple star system. There's Alpha Centauri A and B, and then there's Proxima Centauri which is close enough to have an orbit around the other two, but it is not known for certain whether or not it actually orbits Alpha Centauri A and B, or if it is just in a close encounter with them.
