Basically saying that chemical fuel is not exactly optimal for deep space travel. For escaping earth’s gravity well it is ideal, since high thrust is required rather than specific impulse. Nuclear propulsion becomes the ideal thing after that, generally having low thrust but high specific impulse. I wish I had saved all those Scientific American magazines I used to buy. There were some interesting articles.

This unfortunate fate will inevitably confront us in less than a billion years, when the sun will heat up enough to boil all water off the face of the Earth. With proper planning we could relocate to a new home by then. How friggin' profound...

Hmmm...The PC crowd has missed an important opportunity, for them, to protest these poor size-disadvantaged stars being referred to with such hurtful language...

”A civilization in the habitable zone of a dwarf star like Proxima Centauri might find it hard to get into interstellar space with conventional rockets” Good. The last thing we need is a bunch of aliens from the Proxima Centauri system showing up on our doorstep seeking welfare and demanding that we celebrate their culture.

i especially liked the advice to properly plan our escape from earth within the next billion years. I would suggest no planning of any kind until we are within, say, 5000 years of the need to do so.

If we’re around in ANY corporeal capacity in a billion years it’ll be possible to just move the earth further out...

Since the surface temperature of a warm planet is dictated by the flux of stellar irradiation,.. Wait, what? That sounds like heresy!

Idiot author. If you can’t go direct interstellar you can use nearby moons and planets as gravitational slingshots. Easy peasy.

Why would they use chemical rockets for anything beyond getting off their planet’s surface and into orbit? Solar sails or nuclear engines could take over from there.
