A provocative exploration of dark matter, the Big Bang, and the philosophy of science
Modern cosmology tells us the universe began with a Big Bang, expanded through cosmic inflation, and is now dominated by mysterious forces known as dark matter and dark energy.
But there is a striking fact rarely emphasized:
According to the standard cosmological model, about 95% of the universe consists of phenomena that have never been directly observed.
In When Models Replace Reality, researcher and author Mark Gerard Keenan explores one of the most important questions in modern science:
Where does observation end and theoretical interpretation begin?
A Fresh Look at the Foundations of CosmologyDrawing on cosmology, philosophy of science, and the history of scientific ideas, this book examines the conceptual foundations of our current understanding of the universe.
Inside, readers will explore:
• The role of dark matter in modern cosmology
• The mysterious force of dark energy driving cosmic expansion
• The theory of cosmic inflation and the early universe
• The influence of scientific paradigms on research
• Why modern cosmology relies heavily on theoretical models
Rather than dismissing science, this book invites readers to examine how scientific models evolve and how assumptions can gradually become treated as established reality.
Cosmology at the Frontier of ScienceCosmology asks some of the deepest questions humanity has ever faced:
How did the universe begin?
What is the universe made of?
Why do the laws of nature appear mathematically ordered?
Why does the cosmos seem intelligible at all?
While modern science has produced remarkable discoveries, many of the most fundamental questions remain open.
When Models Replace Reality explores these mysteries while encouraging a renewed commitment to scientific humility, open inquiry, and critical thinking.
Science, Philosophy, and the Search for TruthThroughout history, major advances in science have occurred when researchers questioned long-standing assumptions.
From the shift to heliocentrism to the revolutions of relativity and quantum theory, progress often begins when scientists re-examine the frameworks used to interpret observations.
This book asks whether modern cosmology may be approaching a similar moment of reflection.

The deeper intelligibility of the universe
Written in clear, accessible language, this book is ideal for curious readers, students of science, and anyone interested in the profound questions surrounding the nature of reality.
The universe may be stranger—and more mysterious—than our current models suggest.
Understanding it begins by remembering one essential principle:
Scientific models are tools. Reality is always larger.
