Discovering the Fundamentals of Physical Science

Introduction to Matter and Energy

Physical science is the study of matter, energy, and their interactions. It provides a fundamental understanding of how the world works by focusing on the building blocks of everything around us. Matter can be described as anything that has mass and takes up space. On the other hand, energy is the ability to do work or cause change.

The study of physical science begins with an introduction to matter and energy. In this branch, students learn about atoms—their structure, behavior and properties—and elements which are substances made up of only one type of atom. They also explore the concept of molecules, compounds and mixtures. Through hands-on experiments and research, students see firsthand how different materials interact at the atomic level. By studying matter and energy, scientists have had tremendous impact in areas such as medicine, transportation, aerospace, construction, and technology.

Basic Laws of Motion and Gravity

In addition to matter and energy, the basics laws of motion and gravity play significant roles in physical science. The laws of motion set forth mathematic principles regarding objects in motion—they describe how forces affect these objects. This includes Newton’s First Law of Motion, which states that an object at rest tends to stay at rest, while an object in motion tends to remain in motion unless acted upon by an outside force. These fundamental laws enable scientist to predict how objects will behave under specific conditions and design solutions accordingly.

Gravity is another force that plays a crucial role in physical science. Its influence is felt everywhere—on earth we feel its pull keeping things grounded, but in outer space it helps planets and stars maintain their orbits. One prominent theory related to gravity is Einstein’s Theory of Relativity, which challenged earlier theories on the functioning of the universe. This theory posits that gravity is not a force, but rather the result of the curvature of space and time.

“Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.” -Louis Pasteur

Physical science serves as the foundation for many critical fields such as engineering, medicine, and technology. The study of matter and energy opens new doors in scientific research, while understanding the laws of motion and gravity enables us to design solutions to real-world problems. As we continue exploring this fascinating field, it is important to appreciate its influence on every aspect of our lives. After all, physical science is ultimately about discovering how everything around us works—from the smallest particles to the grandest galaxies.

The Search for Dark Matter and Dark Energy

Scientists have long known that an invisible force works on distant galaxies and affects their motions. However, they cannot detect its origin or meaning using any current technology. As a result, physicists coined the term “dark matter” to refer to this mysterious substance.

Dark matter may consist of weakly-interacting massive particles (WIMPs) or axions. It also could be composed of undiscovered subatomic particles that do not reflect light but exert gravity and interact with ordinary matter through forces yet unknown. Researchers are currently conducting experiments with colliders or underground detectors in hopes of locating dark matter particles.

The universe is also accelerating its expansion rate despite the pull of gravity, a discovery that is as mysterious as it is exciting. Scientists attribute this phenomenon to yet another invisible and unknown source called “dark energy.” Dark energy accounts for around 70% of the universe’s energy density, but scientists remain uncertain about what exactly it comprises or how it functions.

“The discovery that dark energy is driving the accelerated expansion of the universe was the biggest shock in my scientific life, and I’ve been working on this stuff for over fifty years.” -George Smoot
