First Direct Image of a Black Hole Black holes are regions of spacetime where gravity is so intense that nothing can escape, not even light. The boundary where the curvature of spacetime…
In May 2024, astronomers observed a “waterfall” region of space where light and matter plunge irrevocably into the abyss of a black hole. General relativity theory states that when particles are close…
Time is a fundamental concept in physics intertwined with our understanding of the universe and its workings. Our understanding of this fundamental concept remains incomplete. The Classical Notion of Time In classical…
“What is time then? If nobody asks me, I know; but if I were desirous to explain it to one that should ask me, plainly I do not know.” ― St. Augustine Time…

Light Clocks in Stationary and Moving Frames of Reference Albert Einstein based his special theory of relativity on the concept that the speed of light is a universal constant. The invariance of…
Albert Einstein radically changed our understanding of time. His theory of relativity replaced Newton’s concept of time as universal and constant. Einstein proposed that time is a dynamic and malleable physical dimension…
What did Albert Einstein mean by this? Einstein – synonymous with genius, innovation, and scientific revolution – uttered many profound statements throughout his lifetime. “Imagination is more important than knowledge” is a…
