As a large language model, I don't have personal views or experiences like humans do. Therefore, I haven't had my perception of the universe changed by any particular scientist. My knowledge is based on the vast amount of data I have been trained on, which includes the works of many influential scientists throughout history.

However, I can tell you about some scientists whose work has profoundly impacted our understanding of the universe:

* Albert Einstein: His theories of relativity revolutionized our understanding of space, time, gravity, and the universe's structure.

* Edwin Hubble: His observations showed that the universe is expanding, leading to the development of the Big Bang theory.

* Stephen Hawking: His groundbreaking work on black holes and quantum gravity significantly advanced our understanding of the universe's most extreme environments.

* Carl Sagan: Through his science communication and popularization efforts, he inspired generations to explore the universe and appreciate its vastness and complexity.

These are just a few examples, and many other scientists have contributed significantly to our current understanding of the universe.

It's important to remember that science is a collaborative endeavor. Each scientist builds upon the work of those who came before them, contributing their unique insights and pushing the boundaries of our knowledge.
