Discover what exist in the universe
General Relativity and Space-Time Albert Einstein's theory of general relativity, introduced over a century ago, suggests that gravity is not merely a force but a curvature in space-time. Picture a bowling ball placed on a trampoline — that's a massive object creating a warp in the fabric of space-time itself. […]
The Nature of Space-Time Space-time can be visualized as a cosmic fabric. Massive objects like planets or stars create depressions in this fabric, much like a heavy ball on a trampoline. This fundamental concept shapes how celestial bodies move through the universe. We exist in four dimensions: three of space […]
General Relativity and Space-Time Distortion Albert Einstein's theory of general relativity fundamentally changes our understanding of the cosmos. It proposes that massive objects warp the fabric of space-time, similar to how a bowling ball would create a dip on a stretched trampoline. This concept explains gravity not as a force, […]
'Oumuamua's Unique Characteristics 'Oumuamua, with its elongated frame resembling a cigar or a slightly lopsided pancake, defies standard cosmic categories. Its length-to-width ratio of about 6:1 contrasts sharply with the more potato-shaped asteroids typical in our solar system. While asteroids are rocky or metallic and follow predictable paths around the […]
In the vast expanse of our universe, celestial visitors occasionally grace our solar system, sparking curiosity and debate. Such was the case with 'Oumuamua, an object that defied conventional understanding and left scientists pondering its origins and behavior. Discovery and Characteristics of Oumuamua On October 19, 2017, 'Oumuamua was discovered […]
Einstein's Theory of Relativity Einstein's theory of relativity intertwines space and time into a unified fabric of space-time. This cosmic structure bends and flexes with mass and energy, creating gravitational effects. The speed of light, a constant 186,282 miles per second, serves as a universal yardstick. Time dilation, a key […]
Understanding the Fourth Dimension Imagine shapes that extend beyond our familiar three dimensions. In our 3D world, we move along x, y, and z axes—left to right, forward and back, and up and down. Adding a fourth axis, often labeled 'w', opens up new possibilities. A hypercube is a 3D […]
General Relativity and Its Predictions Albert Einstein's general theory of relativity transformed our understanding of gravity. It replaced Newton's concept of invisible strings with the idea of curved space-time. Imagine space as a trampoline with a bowling ball (representing the Sun) creating a dent. Smaller objects, like planets, follow this […]
Detection of DMS on K2-18b NASA's James Webb Space Telescope has potentially detected dimethyl sulfide (DMS) in the atmosphere of K2-18b. This molecule, often produced by marine algae on Earth, hints at possible life beyond our solar system. However, the scientific community remains cautious. Detecting molecules in space relies on […]
Origins of the Universe The universe began about 13.7 billion years ago, compressed into an incredibly tiny point. Cosmic inflation, occurring in less than 10-32 of a second, rapidly expanded the universe faster than light speed. After this initial expansion, the universe settled to form particles that would eventually become […]
