Science is a way to not fool ourselves.

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.

The hole in the ozone layer is a kind of skywriting. At first it seemed to spell out our continuing complacency before a witch's brew of deadly perils. But perhaps it really tells of a newfound talent to work together to protect the global environment.

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.

Researchers keep identifying new species, but they have no idea about the life cycle of a given species or its other hosts. They cut open an animal and find a new species. Where did it come from? What effect does it have on its host? What is its next host? They don't know and they don't have time to find out, because there are too many other species waiting to be discovered and described.
