The ease and likelihood of interstellar rocket travel is a much-debated issue which is relevant to another controversial topic - the value of 'N' - the number of technological civilizations in our Galaxy. It is argued that even if N is as small as 10 - 100, at least one of these will already have been forced, by the termination of the main-sequence evolutionary phase of their home 'Sun', to carry out a massive interstellar migration. If, as is often argued, N ≡ 105, then as many as 104 such migrations may well have taken place. Since each such migration could easily populate the space around more than 106 stars, such large values for N imply that our Galaxy is nearly saturated with extraterrestrial creatures.
