Of course there are worlds. Millions of them! Every star you see has worlds, and most of those you don't see.
Interpretation
The universe is vast and contains countless worlds beyond our imagination.
In this quote, Isaac Asimov emphasizes the immense number of worlds that exist throughout the universe, each star potentially hosting its own planets. This perspective encourages us to consider the complexity and possibility of life in places we cannot yet see, urging a sense of wonder and curiosity about the cosmos.
In practice
During a science lecture to inspire students about astronomy.
Democracy cannot survive overpopulation. Human dignity cannot survive it. Convenience and decency cannot survive it. As you put more and more people into the world, the value of life not only declines, but it disappears. It doesn't matter if someone dies.
Science does not promise absolute truth, nor does it consider that such a thing necessarily exists. Science does not even promise that everything in the Universe is amenable to the scientific process.
Democracy cannot survive overpopulation.
Although the time of death is approaching me, I am not afraid of dying and going to Hell or (what would be considerably worse) going to the popularized version of Heaven. I expect death to be nothingness and, for removing me from all possible fears of death, I am thankful to atheism.
A subtle thought that is in error may yet give rise to fruitful inquiry that can establish truths of great value.
During the century after Newton, it was still possible for a man of unusual attainments to master all fields of scientific knowledge. But by 1800, this had become entirely impracticable.
When asked if I am pessimistic or optimistic about the future, my answer is always the same: If you look at the science about what is happening on Earth and aren't pessimistic, you don't understand the data.
If Watson and I had not discovered the [DNA] structure, instead of being revealed with a flourish it would have trickled out and that its impact would have been far less. For this sort of reason Stent had argued that a scientific discovery is more akin to a work of art than is generally admitted. Style, he argues, is as important as content. I am not completely convinced by this argument, at least in this case.
The only relevant test of the validity of a hypothesis is comparison of prediction with experience.
One day I went up to my mom and I said, 'Mom, can I have permission to build a 2.3-million electron-volt atom smasher - a betatron - in the garage?' And my mom stared at me, and she said, 'Sure. Why not? And don't forget to take out the garbage.'
The human brain is an incredible pattern-matching machine.
It has been a bitter mortification for me to digest the conclusion that the "race is for the strong" and that I shall probably do little more but be content to admire the strides others made in science.
