Things Worth Noting
Scientists are making real progress toward a unified theory of quantum gravity, aiming to link quantum mechanics with general relativity at the tiny Planck scale. Key approaches like string theory, loop quantum gravity, emergent gravity, and holography offer new ways to explain space-time, black holes, and the early universe. In 2025, breakthroughs from Aalto University […]
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 […]
