Normal Matter vs. Dark Matter Normal matter, comprising less than 5% of the universe, is made of protons, neutrons, and electrons. It's visible, tangible, and forms everything from planets to living beings. Dark matter, accounting for about 27% of the universe, doesn't interact with light and is only detectable through […]
Fundamentals of Redshift The concept of redshift is analogous to the Doppler effect observed with sound waves. When light travels towards an observer, the waves compress, shifting the color towards the blue end of the spectrum (blueshift). Conversely, when light sources move away, the waves stretch, shifting towards the red […]
The universe, with its boundless expanse and intricate dance of celestial bodies, has long captivated astronomers and scientists. As we look to the stars, we uncover stories of cosmic expansion and the forces that shape our understanding of space and time. This journey through the cosmos reveals the mysteries of […]

The Evolution of Astrology and Astronomy Astrology originated in ancient Babylonia roughly 2,500 years ago. The Babylonians believed celestial bodies influenced the fortunes of kings and nations. Later, the Greeks introduced natal astrology to the Western world, suggesting an individual's fate was tied to the celestial arrangement at their birth. […]
Nature of Sound Waves Sound waves are mechanical waves that require a medium to propagate. They transfer energy through the physical interaction of molecules, similar to the movement of a Slinky toy. When these pressure waves reach our eardrums, they cause vibrations that our brains interpret as sound. In space, […]
