Why Are Neutron Stars So Dense?
The Life and Death of Massive Stars The story of neutron star density begins with massive stars. Stars shine by fusing lighter elements into heavier ones in their cores. This nuclear fusion releases energy that pushes outward, balancing the inward pull of gravity. As long as this balance exists, the star remains stable.

What are neutron stars made of?
The Birth of a Neutron Star To understand what neutron stars are made of, we must begin with how they form. Neutron stars are created during core-collapse supernovae. When a massive star runs out of nuclear fuel, its core collapses under gravity. If the core is not massive enough to become a black hole, it rebounds into a neutron star.

What Is Polarization of Light?
Understanding Light as a Wave To understand polarization, we must first understand light as a wave. Light is an electromagnetic wave, meaning it consists of oscillating electric and magnetic fields that travel through space. These oscillations occur perpendicular to the direction the light is moving.

Why Is the Sky Blue?
What Color Is Sunlight? To understand why the sky is blue, we must start with sunlight. Although sunlight looks white to our eyes, it is actually a mixture of many colors. When passed through a prism, sunlight spreads out into a rainbow of colors: red, orange, yellow, green, blue, indigo, and violet.

How Does Light Bend Near Massive Objects?
The Classical View of Light and Gravity Before Einstein, classical physics treated gravity as a force acting between masses. Since light has no rest mass, it was assumed that photons would not be affected by gravity. In this view, light always travels in straight lines, and any apparent deflection would have to come from interactions with matter, not gravity itself.

Can Light Be Slowed Down or Stopped?
How Fast Does Light Normally Travel? In a perfect vacuum, light travels at a constant speed known as c, approximately 299,792 kilometers per second. This speed is a fundamental constant of nature and represents the maximum speed at which information can travel.

Is Light a Wave or a Particle?
What Is Light? Light is a form of electromagnetic radiation. It carries energy, travels through empty space, and allows us to see the universe. From radio waves to gamma rays, light spans a vast spectrum, but visible light is only a small part of it.
