Space is commonly described as silent because sound does not travel through it in the way it does on Earth. This silence is not due to a lack of events or energy, but to the physical conditions of space itself. Sound depends on specific mechanisms to propagate, and those mechanisms are largely absent beyond planetary … Read more
Is the Universe Actually Infinite Infinity describes the absence of limits in size, extent, or quantity. In cosmology, the concept is applied to the total size and structure of the universe rather than to observable measurements alone. Scientific discussion of infinity relies on physical models, geometry, and observational constraints. The question of whether the universe … Read more
What If the Sun Suddenly Disappeared The Sun is the dominant source of mass and energy in the solar system. Its gravity governs planetary orbits, and its radiation maintains surface temperatures, atmospheric circulation, and biological activity on Earth. A sudden disappearance of the Sun would remove both gravitational binding and incoming solar energy. The resulting … Read more
Understanding the Interior of Black Holes Black holes are regions of spacetime where gravity becomes strong enough to prevent anything, including light, from escaping. They form when large amounts of mass collapse into a compact volume, most commonly after the death of massive stars. Their existence is supported by both theoretical models and astronomical observations. … Read more
