Explore the fundamental laws of nature, major scientific theories, breakthroughs, and the impact of science on society.
Fire rainbows, scientifically known as circumhorizontal arcs, are rare optical phenomena that require very specific conditions to be observed. The foremost requirement is a high sun altitude—specifically, the sun must be at least 58° above the horizon. This high position ensures that sunlight enters...
ViewOur latest research shows that Einstein’s theories still guide us today, where near-light speeds and warped spacetime yield remarkable time dilation effects, hinting at genuine time travel possibilities [1][8]. Recent studies using closed timelike curves reveal that spacetime may loop back on itself...
ViewImagine a universe where majestic stars reveal the secrets of time, their powerful gravity bending the very fabric of reality. In these celestial arenas, Einstein’s theories come to life, as gravity near massive stars and black holes slows time down, a phenomenon confirmed by scientific studies [3][...
ViewIn the cosmic nursery, when a star is born from a collapsing cloud, a swirling circumstellar disc of gas and dust forms around it [1][3]. Within this majestic disc, tiny grains collide and cling together, forming pebbles that grow into larger planetesimals— the building blocks that slowly accrete in...
ViewOur understanding of the universe begins with distinguishing between the part we can observe and the entire cosmos. The observable universe refers to the region from which light has had time to reach us since the beginning of cosmic expansion, while the entire universe encompasses all of space and m...
ViewNeutron stars are incredibly hot celestial objects, with surface temperatures reaching over 10 million Kelvin (K) at the time of their formation. However, they do not produce heat through nuclear fusion like many other stars. Instead, they cool over time, and their surface temperatures can drop sign...
ViewIn a quasar, while the environment is extremely hot, the water vapor still exists due to its specific conditions. The quasar emits immense energy, heating the surrounding gas and dust, creating a region with water vapor that is described as “unusually warm and dense” compared to typical conditions i...
ViewIn the vast cosmos, astronomers have uncovered a colossal reservoir of water, an ocean 140 trillion times the volume of Earth’s own [1][2]. This immense body, bathed in the energetic glow of a quasar more than 12 billion light‐years away, clusters around a feeding black hole [3][4]. Imagine water th...

ViewIn the great theatre of nature, supercells emerge as majestic thunderstorms when warm, moist air swiftly ascends, nourished by high instability [10][7][6]. They develop under the influence of wind shear, which organizes the rising air into a rotating updraft, the mesocyclone, while capping inversion...
ViewThunderstorms are powerful due to the rapid rise of warm, moist air, which creates instability in the atmosphere. As this air ascends, it cools and condenses, forming cumulonimbus clouds that can reach great heights, sometimes over 10,000 meters, leading to intense weather phenomena. The strength of...
