Things Worth Noting
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 […]
Zero-point energy (ZPE) is the lowest energy a quantum system can have, rooted in quantum mechanics and quantum field theory. It arises from the Heisenberg uncertainty principle, causing quantum fluctuations in the vacuum, even at absolute zero. The Casimir effect proves ZPE, showing plates attract due to vacuum energy pressure. The Lamb shift, a shift […]
