Things Worth Noting
Space: The first direct observation of gravitational waves detected two merging black holes, emitting 36 septillion yottawatts (3.6×10⁴⁹ watts), surpassing the total light radiated by all stars in the observable universe.

Black holes are regions in space with gravity so strong that nothing, not even light, can escape. They form when massive stars collapse or dense objects merge. Their intense gravity warps space-time, making them invisible except for effects like orbiting gas or light bending. Supermassive black holes exist in galaxy centers, influencing star formation. Studying […]
Is time travel possible? Einstein’s theory of relativity suggests it might be. Special relativity shows time dilation, where fast-moving objects age slower, as seen with astronauts. General relativity allows for closed timelike curves, theoretical paths to the past via wormholes or black holes. Wormholes, or Einstein-Rosen bridges, could connect different times but need exotic matter […]
CERN’s Large Hadron Collider (LHC) explores black holes, sparking curiosity in particle physics and cosmology. The LHC’s high-energy collisions, analyzed by ATLAS and CMS detectors, aim to uncover phenomena like the Higgs boson and dark matter, while testing theories of micro black holes. These tiny black holes, tied to extra dimensions and quantum gravity, would […]
