Dark Matter What is Dark Matter? Dark Matter is a mysterious form of matter that does not emit, absorb, or reflect light. That means we cannot see it directly, but we know it exists because of the gravitational effects it has on visible matter, like galaxies and stars. Evidence for Dark Matter Galaxies rotate faster […]

Decoherence What is Decoherence? Decoherence is a concept in quantum mechanics that explains why quantum behavior disappears when we observe a system. In the quantum world, particles can exist in many states at once, a condition called superposition. But in the everyday world, we don’t see this. Decoherence describes how interactions with the environment cause
Compare the Idea of Gravitation Given by Newton and Einstein Introduction Both Isaac Newton and Albert Einstein gave influential theories of gravitation that shaped our understanding of the universe. Newton’s theory explained gravity as a force between two masses, while Einstein introduced a more advanced idea where gravity is not a force but a curve

Write a Note on the Contribution of Kepler to Cosmology Introduction Johannes Kepler (1571–1630) was a German astronomer and mathematician who made significant contributions to cosmology. His work helped lay the foundation for modern astronomy and supported the shift from geocentric (Earth-centered) to heliocentric (Sun-centered) models of the universe. Major Contributions 1. Kepler’s Laws of

Write a Note on the Philosophical Implications of Quantum Mechanics Introduction Quantum mechanics is a branch of physics that describes the behavior of particles at the smallest scales. It has challenged traditional views of reality and raised important philosophical questions about determinism, observation, and the nature of reality. Main Philosophical Implications 1. Uncertainty and Indeterminism

Highlight the Main Features of Feminist Account of Science Introduction The feminist account of science questions how traditional science has been influenced by male-dominated perspectives. It seeks to bring in women’s experiences and viewpoints to make science more inclusive, fair, and socially responsible. Main Features of Feminist Science 1. Critique of Objectivity Feminist thinkers argue

Write a Note on the Aupanishdik Understanding of Cosmology Introduction The Upanishads are ancient Indian spiritual texts that explore deep philosophical ideas. They offer a unique perspective on cosmology—the study of the origin and structure of the universe. Unlike modern science, the Aupanishdik (Upanishadic) view of cosmology is spiritual and metaphysical rather than physical and
