Which Questions Can Be Answered By Science?

Science has revealed an astonishing amount about the natural world and universe we live in. But there are limitations on the types of questions and phenomena science is equipped to address.

If you’re short on time, here’s a quick answer to your question: Science can answer empirical questions about the observable universe, but cannot address subjective experiences, supernatural claims, or moral and ethical questions.

In this article, we’ll explore the scope of scientific inquiry and examples of questions that do and don’t fall under the purview of science.

Empirical Questions About the Natural World

Science plays a crucial role in answering questions about the natural world. Through a systematic and evidence-based approach, scientists are able to provide explanations, make predictions, and develop practical applications that benefit society.

Here are three key aspects of scientific inquiry that help answer empirical questions about the natural world.

Mechanistic Explanations

One way science answers questions about the natural world is by providing mechanistic explanations. These explanations seek to understand the underlying mechanisms and processes that govern various phenomena.

By studying cause-and-effect relationships, scientists can uncover the fundamental principles that drive the behavior of natural systems.

For example, in the field of biology, scientists have been able to explain the mechanism of photosynthesis, whereby plants convert sunlight into energy. Through rigorous experimentation and observation, they have discovered the complex biochemical processes involved in this vital biological function.

Such mechanistic explanations not only deepen our understanding of the natural world but also have practical implications, such as improving agricultural practices and developing renewable energy technologies.

Predictive Models

Science also relies on predictive models to answer questions about the natural world. These models are mathematical representations of observed phenomena and are used to make predictions about future events or behaviors.

By analyzing data and identifying patterns, scientists can develop models that accurately predict outcomes and help us understand complex systems.

For instance, in the field of meteorology, scientists use sophisticated models to forecast weather patterns and predict the likelihood of severe storms. These models take into account a wide range of variables, such as temperature, humidity, wind speed, and atmospheric pressure, to generate forecasts with a high degree of accuracy.

Predictive models not only help us plan our daily activities but also assist in managing natural disasters and mitigating their impact.

Technological Applications

Science has a direct impact on our daily lives through its technological applications. By answering questions about the natural world, scientists often develop innovative technologies that enhance our quality of life and drive economic growth.

These technological advancements are based on scientific principles and aim to solve practical problems or meet societal needs.

For example, the field of medicine has seen remarkable advancements due to scientific research. From the development of vaccines to the discovery of life-saving drugs, science has revolutionized healthcare and improved human well-being.

Additionally, technological applications in fields such as communication, transportation, and energy have transformed the way we live and interact with the world around us.

Beyond the Limits of Science

While science is a powerful tool for understanding and explaining the natural world, there are certain questions that lie beyond its reach. These questions often delve into the realms of subjective experiences, metaphysics, and ethics.

They are important to consider because they shape our understanding of the world and influence our beliefs and actions. Let’s explore some of these intriguing areas that science cannot fully address.

Subjective Experiences

One area where science faces limitations is in explaining subjective experiences. These include emotions, consciousness, and the sense of self. While science can study the brain and its neural activities associated with these experiences, it cannot fully capture the subjective nature of what it feels like to be human.

For instance, science can measure brain activity during a joyful moment, but it cannot truly understand the feeling of happiness. It is in these subjective experiences that science and philosophy intersect, each offering unique insights.

Metaphysics and Supernatural Claims

Metaphysics deals with questions about the nature of reality that go beyond the physical world. It explores concepts such as the existence of God, the nature of consciousness, and the origin of the universe.

Science relies on empirical evidence and observation to formulate theories, while metaphysics often delves into the realm of speculation and philosophical inquiry. While science can provide explanations for natural phenomena, it cannot prove or disprove the existence of supernatural entities or phenomena.

Supernatural claims, such as miracles or paranormal events, are often beyond the scope of scientific inquiry. These claims often lack empirical evidence and are difficult to reproduce in controlled environments.

However, it is important to note that science has debunked many supernatural claims throughout history, providing alternative explanations based on natural phenomena.

Moral and Ethical Questions

Moral and ethical questions also lie beyond the limits of science. While science can provide information about the consequences of certain actions or behaviors, it cannot determine what is morally right or wrong.

Moral and ethical frameworks are shaped by cultural, religious, and philosophical beliefs, and these frameworks vary across societies and individuals. Science can inform ethical discussions by providing empirical data and insights, but ultimately, moral judgments are subjective and deeply personal.

It is important to recognize that science and morality can complement each other. Scientific knowledge can help inform ethical decision-making by providing evidence on the consequences of certain actions.

However, the ultimate determination of what is morally right or wrong goes beyond scientific inquiry and relies on individual and societal values.

While science has made remarkable progress in unraveling the mysteries of the universe, there are still questions that lie beyond its reach. Subjective experiences, metaphysics, and moral and ethical questions all invite us to explore the realms beyond what can be answered by science alone.

By embracing both scientific and philosophical inquiry, we can gain a more holistic understanding of the world and our place in it.

The Interplay Between Science and Other Disciplines

Science does not exist in isolation; it often collaborates with other disciplines to answer complex questions. The interplay between science and these other fields has led to significant advancements and a deeper understanding of the world we live in.

Collaborations with Social Sciences

Science and social sciences often work hand in hand to investigate and address societal issues. For example, psychologists and neuroscientists collaborate to understand the relationship between behavior and brain activity.

This interdisciplinary approach has shed light on topics such as addiction, mental health, and decision-making processes. By combining the methodologies and theories from both fields, researchers can provide a more comprehensive understanding of human behavior.

Another example of collaboration is between anthropologists and geneticists. Together, they can examine the genetic history of different populations and how it relates to cultural practices and migration patterns.

This collaboration has allowed scientists to trace human evolution and migration routes, providing valuable insights into our shared history.

Informing Policy and Law

Science plays a crucial role in informing policy and law decisions. Policymakers often rely on scientific research to make informed choices that impact society. For instance, studies on climate change have provided policymakers with evidence on the consequences of human activities on the environment.

This information has influenced the development of policies aimed at reducing greenhouse gas emissions and promoting sustainable practices.

Additionally, forensic science has been instrumental in the legal system. DNA analysis, fingerprinting, and other scientific techniques are used to provide evidence in criminal investigations and court proceedings.

The collaboration between science and law enforcement has significantly improved the accuracy and reliability of forensic evidence, leading to more just outcomes in the criminal justice system.

Improving Philosophy

Science has also contributed to the field of philosophy by challenging and refining philosophical concepts and theories. For example, discoveries in neuroscience have raised questions about the nature of consciousness and free will.

Philosophers and neuroscientists collaborate to explore these topics, bridging the gap between empirical evidence and philosophical inquiry.

Furthermore, advancements in physics, such as quantum mechanics, have posed philosophical questions about the nature of reality and our understanding of the universe. This intersection of science and philosophy encourages critical thinking and a deeper exploration of fundamental questions about existence and knowledge.

The interplay between science and other disciplines is essential for advancing knowledge and addressing complex issues. By collaborating with social sciences, informing policy and law decisions, and improving philosophy, science continues to shape our understanding of the world and drive progress.


While remarkably powerful, science does have limits in terms of the types of questions it can meaningfully address. Science is confined to empirical claims about the observable universe and cannot evaluate subjective experiences, metaphysical concepts, or ethical and moral questions.

Identifying the boundaries of science clarifies its capabilities and limitations. This enables focusing scientific efforts on productive domains of inquiry where empirical data can inform mechanistic explanations of the natural world.
