Video Information

Tonight on The Sleepy Scientist, we will be gently exploring one of the strangest questions in physics: is time real? From ancient skywatchers following the Sun, Moon, tides, and seasons, to Newton’s absolute time, Einstein’s relativity, entropy, black holes, quantum mechanics, and the mystery of the present moment, this calm journey looks at why time feels so obvious in daily life, yet becomes deeply strange when science looks closely.

Time can be measured by clocks, stretched by motion, slowed by gravity, and written into the history of the universe itself. But modern physics also suggests that time may not be a single universal river flowing evenly through everything. So settle in, get comfortable, and drift through the quiet mystery of clocks, stars, memories, distant light, and the question of whether time is fundamental, emergent, or something stranger than either.
