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.

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.
At the simplest level, economics can better show us the consequences of our actions. Less simple are cases in which we don't have the knowledge to predict the full consequences. Global warming and climate change are examples.
The universe has really never made things in ones. The Earth is special and everything else is different? No, weβve got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, itβs one of a hundred billion galaxies. And the universe - maybe itβs countless other universes.
Water is the key to dealing with the twin challenges of poverty and growth.
Nothing in biology makes sense except in the light of evolution.
Perhaps one day earthquakes, hurricanes and financial crashes will all be predictable. But we don't have to wait until then for seismology, meteorology and economics to become sciences; they already are.
Any difficulties which the world faces today will be as nothing compared to the full effects which global warming will have on the world-wide economy.
