"Every galaxy we see in the universe has arisen from a seed that was there at the beginning."
This quote by Margaret Geller suggests a cosmological perspective where every observable galaxy in the universe is considered as an offspring or "seed" of a primordial event or state that existed at the beginning, possibly referring to the Big Bang. In other words, the structure and existence of galaxies today are thought to be a result of the initial conditions set forth during the birth of the universe. This idea highlights the interconnectedness and continuity in the cosmic evolution process, as well as our quest to understand the underlying laws that govern such vast structures.
"The large scale structure of the universe seems to have been determined at an early stage and then evolved gradually under gravity."
This quote implies that the grand structure of the universe, including its largest features like galaxies and clusters, was largely set in place during the early stages of cosmic expansion (Big Bang). The evolution since then has been primarily influenced by gravity, with smaller structures gradually forming and coalescing within this established framework, rather than drastic changes reshaping the large-scale structure over time.
"We're trying to understand the cosmic web, the distribution of matter throughout the universe."
This quote highlights the quest for scientific understanding of the large-scale structure of the universe. The "cosmic web" refers metaphorically to the network-like pattern formed by the distribution of matter, which includes galaxies, clusters, and other cosmic entities. Scientists like Margaret Geller are trying to decipher this pattern and its underlying principles, aiming to unveil more about the evolution, composition, and fundamental laws governing our universe.
"The universe is not random; there are patterns that can be discerned if you look carefully enough."
This quote by Margaret Geller emphasizes the idea that the universe, despite its vastness and complexity, is not chaotic or arbitrary, but rather follows certain patterns and principles. It encourages us to observe and scrutinize our surroundings closely in order to understand these underlying patterns and make connections that may seem hidden at first glance. This perspective invites a sense of wonder and curiosity, as well as a recognition that there are laws and structures governing the cosmos which we can strive to comprehend and appreciate.
"It's incredibly exciting to be living at a time when we are really starting to understand the origins and fate of our universe."
This quote by Margaret Geller encapsulates the sense of wonder and curiosity that drives scientific exploration, particularly in cosmology. She is expressing her enthusiasm for being alive during an era where humanity is making significant strides in understanding the mysteries of the universe, its origins, and its ultimate fate. This sense of awe, discovery, and progress reflects the human spirit's relentless pursuit of knowledge about our place in the cosmos.
Hunger, inadequate medical care, poor housing, and inferior schools are enemies of the sense of wonder. It is easier and less expensive in the long run to prevent a loss of imagination by providing adequate nutrition, housing, medical care, and schooling than it is to try to restore that loss.

At least in part, people are attracted to subjects where they can identify at a basic level with the people who do it. The extraordinary aesthetic of the natural world is not obvious to someone who never leaves the inner city. Appreciation of the elegance and power of physical law is an acquired taste.

When we look out into space, we're looking back in time; the light from a galaxy a billion light-years away, for instance, will take a billion years to reach us. It's an amazing thing. The history is there for us to see. It's not mushed up like the geologic record of Earth. You can just see it exactly as it was.
