How do studies and discoveries about the universe affect our lives?
They increasingly have taken humans out of the centre of the universe and to some extent "put us in our place"
Four hundred years ago, people thought that the Earth, the sun, and the planets revolved around us, making us the center of the universe. However, early astronomers showed that this was not the case and that Earth actually revolved around the sun. Scientific discoveries about the galaxy revealed that our galaxy contained only a few billion galaxies, not the entire universe, but rather one spiral arm of the Milky Way galaxy. The big bang theory also revealed that our galaxy was one of many billions in the visible universe.
In biology, the concept of evolution also somewhat dethroned us by demonstrating that we were only a single branch in an intricate web of life, not the apex of evolution.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
