SUMMARY
The Earth's orbit around the Sun is indeed shifting due to various factors, including mass loss from the Sun and gravitational influences from other celestial bodies. Current time measurement relies on atomic clocks, which necessitate the insertion of leap seconds to align with solar time. A proposal exists to abandon leap seconds, allowing atomic time to diverge from solar time. Additionally, the Earth is gradually moving closer to the Sun at a rate of nearly one millimeter per century, a phenomenon that has received insufficient attention.
PREREQUISITES
- Understanding of gravitational forces in astrophysics
