Things Worth Noting
Time dilation, a key concept in Einstein’s relativity, explains why time stretches for objects moving fast or in strong gravitational fields. In special relativity, time slows for a moving observer relative to a stationary one, as shown by the Lorentz factor, where higher speeds near the speed of light stretch time more. For example, muons […]
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 […]
