Interstellar Travel Quotes

“There needs to be an intersection of the set of people who wish to go, and the set of people who can afford to go...and that intersection of sets has to be enough to establish a self-sustaining civilisation. My rough guess is that for a half-million dollars, there are enough people that could afford to go and would want to go. But it’s not going to be a vacation jaunt. It’s going to be saving up all your money and selling all your stuff, like when people moved to the early American colonies...even at a million people you’re assuming an incredible amount of productivity per person, because you would need to recreate the entire industrial base on Mars. You would need to mine and refine all of these different materials, in a much more difficult environment than Earth. There would be no trees growing. There would be no oxygen or nitrogen that are just there. No oil.Excluding organic growth, if you could take 100 people at a time, you would need 10,000 trips to get to a million people. But you would also need a lot of cargo to support those people. In fact, your cargo to person ratio is going to be quite high. It would probably be 10 cargo trips for every human trip, so more like 100,000 trips. And we’re talking 100,000 trips of a giant spaceship...If we can establish a Mars colony, we can almost certainly colonise the whole Solar System, because we’ll have created a strong economic forcing function for the improvement of space travel. We’ll go to the moons of Jupiter, at least some of the outer ones for sure, and probably Titan on Saturn, and the asteroids. Once we have that forcing function, and an Earth-to-Mars economy, we’ll cover the whole Solar System. But the key is that we have to make the Mars thing work. If we’re going to have any chance of sending stuff to other star systems, we need to be laser-focused on becoming a multi-planet civilisation. That’s the next step.”

“It’s pretty hard to get to another star system. Alpha Centauri is four light years away, so if you go at 10 per cent of the speed of light, it’s going to take you 40 years, and that’s assuming you can instantly reach that speed, which isn’t going to be the case. You have to accelerate. You have to build up to 20 or 30 per cent and then slow down, assuming you want to stay at Alpha Centauri and not go zipping past. It’s just hard. With current life spans, you need generational ships. You need antimatter drives, because that’s the most mass-efficient. It’s doable, but it’s super slow.”

“Dear Sirs," Flick began before loudly inhaling, "On account of there being no heat down here in account of the being no electricity on account of the brand-new energy rations so thoughtfully and nobly and honorably imposed on the steerage decks by Sovereign Nicolaeus on account of the blackouts - Aster fell prey to a brief fit of hypothermia-induced delirium de spoke against you in her maddery. She's healed up now so you don't have to worry about it happening again.”
― Rivers Solomon, An Unkindness of Ghosts

“A brave new future had been charted, and none of them knew where it was going to lead.

From my upcoming novel,Frontiers, the sequel to Cybersp@ce and the second in the trilogy.”

“Interstellar travel is like a flight to Australia on acid.”
― Stewart Stafford

“In conclusion, I return to Einstein. If we find a planet in the Alpha Centauri system, its image, captured by a camera travelling at a fifth of light speed, will be slightly distorted due to the effects of special relativity. It would be the first time a spacecraft has flown fast enough to see such effects. In fact, Einstein’s theory is central to the whole mission. Without it we would have neither lasers nor the ability to perform the calculations necessary for guidance, imaging and data transmission over twenty-five trillion miles at a fifth of light speed.
We can see a pathway between that sixteen-year-old boy dreaming of riding on a light beam and our own dream, which we are planning to turn into a reality, of riding our own light beam to the stars. We are standing at the threshold of a new era. Human colonisation on other planets is no longer science fiction. It can be science fact. The human race has existed as a separate species for about two million years. Civilisation began about 10,000 years ago, and the rate of development has been steadily increasing. If humanity is to continue for another million years, our future lies in boldly going where no one else has gone before.
I hope for the best. I have to. We have no other option.”
― Stephen Hawking, Brief Answers to the Big Questions

“She awoke on the ship, alone, certain of only those two things. That she was aboard a vessel moving through space and that there was absolutely no one else on it.”
― Brian J. Dolan, Notes from Star to Star

“There are problems humans cannot solve, to wit: density dependent birth rates, loss of genetic diversity, the overturning of his population pyramid, traveling to the nearest star, and the extinction of Man.”
