Comment Oh really?? (Score 1) 71

To travel 40 trillion km in 400 years means an average speed of about 3168 km/s. And this ship is 58km long?? let's assume it's 58km x 100m x 100m with an average density half that of water. That gives us a mass of about 290 billion kg. To accelerate 290 billion kg up to 3168 km/s will take about 1.46 * 10^24 joules, or roughly as much energy as everyone on Earth consumes in 2500 years.

Good luck with that.

Oh, that's going to help the US's "AI Strategy" immensely. And while some advanced chip manufacturing is starting to be done in the USA, I doubt you could build a computer with entirely US-made components unless you were willing to pay a lot more.

And of course, Asian countries can retaliate because they probably can make anything they need outside of the USA.
