That's not a miracle dumbass, it's science. The same science that says a generational ship is not remotely possible right now.

Which part of the technology exists? We use gravity to throw shit around the solar system because it becomes exponentially harder to launch a ship with enough fuel to do anything else. The space station is constantly resupplied. I'm curious which part of this is feasible to you.

We couldn't even build the ship, never mind put people on it. We're a long ways off.
