Physics: Flat Universe
The concept of a “flat universe” is a pivotal idea in modern cosmology, emerging from the interplay between Einstein’s theory of general relativity and the Friedmann–Lemaître–Robertson–Walker (FLRW) metric. General relativity, proposed by Albert Einstein in 1915, revolutionized our understanding of gravity by describing it as the curvature of spacetime caused by mass and energy. The…

Physics: Varying Speed of Light
The speed of light in a vacuum, precisely measured at approximately 299,792,458 meters per second, stands as one of the most pivotal and unshakeable constants in the realm of physics. This value, often rounded to 300,000 kilometers per second for simplicity, is far more than a mere numerical curiosity—it is a foundational pillar that supports…

Physics: Symmetry
The Profound Role of Symmetry in Physics Symmetry in physics is a profound and unifying concept that has fundamentally shaped our understanding of the universe. At its essence, symmetry refers to the invariance of physical systems under specific transformations—be they spatial shifts, temporal changes, or more abstract internal alterations. This principle, when expressed through the…

Physics: Making the Cosmic Microwave Background and new scientific quests
The Cosmic Microwave Background: Standard Model and Beyond The cosmic microwave background (CMB) is widely regarded as a snapshot of the oldest light in our universe, dating back to the Big Bang approximately 13.8 billion years ago. In the standard cosmological model, the CMB represents the thermal radiation left over from a hot, dense phase…

Health: Asthma and COPD
Chronic Obstructive Pulmonary Disease (COPD) and asthma are two prevalent respiratory conditions that affect millions of people globally, including a significant portion of the population in the UK. While they may present with overlapping symptoms—such as shortness of breath, coughing, and wheezing—they are fundamentally distinct diseases with unique biological mechanisms, causes, risk factors, diagnostic approaches,…

Physics: Zero point energy
Zero point energy (ZPE) is one of the most fascinating and enigmatic concepts in modern physics, rooted deeply in the framework of quantum mechanics. It refers to the lowest possible energy that a quantum mechanical system can possess, a baseline that persists even when all other forms of energy have been stripped away, such as…

Science: The Double Slit Experiment
The double-slit experiment is far more than a simple demonstration of interference patterns; it serves as a profound window into the enigmatic fabric of reality itself. At its core, this iconic experiment reveals that when quantum particles—such as photons or electrons—are directed toward a barrier pierced by two closely spaced slits, they produce an interference…
