it'd take about 6 million tons of fuel (about the mass of the Pyramids of Egypt or 2,000 Saturn V rockets)
That is assuming constant energy consumption to sustain 1g, but unfortunately that's not the case, the closer you get to the speed of light, the more energy you'd need to sustain 1g, and this becomes unrealistic long before you are anywhere close to the speed of light.
- panic 10y agoYour speed doesn't affect the laws of physics you experience.
- dragonwriter 10y agoIts probably more clear to say that a constant 1G acceleration in the local reference frame takes constant fuel, but produces a progressively smaller acceleration (asymptotically approaching zero as speed in the fixed frame approaches c) in the fixed reference frame you were launched in (or of the point you are trying to reach, the logic is equivalent) because relativity.
