Imagine we could accelerate continuously at 1 g-what we're comfortable with on good old terra firma-to the midpoint of our voyage, and decelerate continuously at 1 g until we arrive at our destination. It would take a day to get to Mars, a week and a half to Pluto, a year to the Oort Cloud, and a few years to the nearest stars.

Interpretation

What this quote means

The quote describes the possibilities of space travel using continuous acceleration and deceleration to reach distant destinations relatively quickly.

In this quote, Carl Sagan imagines a future in which humanity can travel through space at a constant acceleration of 1 g, the gravitational pull experienced on Earth. By maintaining such acceleration, he argues that journeying to other celestial bodies within our solar system and even to the nearest stars would become feasible within a timeframe that is much shorter than what is currently possible, highlighting the immense potential of advanced space travel technology.

There is a reward structure in science that is very interesting: Our highest honors go to those who disprove the findings of the most revered among us. So Einstein is revered not just because he made so many fundamental contributions to science, but because he found an imperfection in the fundamental contribution of Isaac Newton.
