We know that on earth, a day is 24 hours long. but why? on july 5, 2023, a team of astrophysicists from the university of toronto explained how the effects of the sun and moon result in a 24 hour.
Why A Day Is 24 Hours Long And Why It Used To Be 20 Hours This 'stalling' of earth's day length at 19 hours lasted roughly 1 billion years and was the result of a delicate balance of opposing forces in our planet's distant past, the study from two geophysicists suggests. earth's day length 'stalled' at 19 hours for 1 billion years. (mitchell & kirscher, nature geoscience, 2023). Here’s how it works. once every 24 hours, earth completes one rotation on its axis, marking one day on our planet. this reliable rotational period is what allowed humans to develop systems to.
