Does Earth's Mass Affect the Length of a Day?

Click For Summary
SUMMARY

The discussion confirms that an increase in Earth's mass does affect the perception of time for a remote observer. Specifically, as Earth's mass increases, the rate at which time passes on Earth appears to decrease when compared to the time experienced by an observer located away from Earth. While individuals on Earth would not perceive any change in their own time passage, they would observe that time appears to pass more quickly for distant observers. This phenomenon is rooted in the principles of general relativity.

PREREQUISITES
  • Understanding of general relativity
  • Familiarity with time dilation concepts
  • Basic knowledge of gravitational effects on time
  • Awareness of observational perspectives in physics
NEXT STEPS
  • Research the implications of general relativity on time perception
  • Explore the concept of time dilation in varying gravitational fields
  • Study the effects of mass on spacetime curvature
  • Investigate how different observers perceive time in relativistic contexts
USEFUL FOR

Physicists, students of relativity, and anyone interested in the effects of mass on time perception will benefit from this discussion.

Is it true that the time increase (24 hrs becomes 25 or 26 or..)when the mass of Earth is increase? ??

Not locally, but relative to a remote observer, yes.

Indeed. The rate that time passes on Earth, when viewed by an observer away from Earth, would decrease. For every second that ticked by on the observer's watch, less than a second would pass on Earth. On the Earth, you and I would not notice any change in our own rate of time passage, but we would notice that time passes faster for an observer away from Earth.
