"Weightless" just means that the supporting force on them is zero and thus they experience no stress from such a force. It does not mean that they experience zero gravitational force. After all, it's the gravitational force that holds them in orbit! Any projectile in free fall is "weightless".Lazzini said:
No.Lazzini said:
Once it's lying on the equator, you can measure it's weight.Lazzini said:
Yes - I appreciate that, and just as a geostationary satellite experiences no stress from such a force, why would that not also be true of a body lying on the equator of the expanded Earth?Doc Al said:
Actually, you are correct! If you rest a mass on the surface of a giant Earth the size of a geosynchronous orbit it would register zero weight on a bathroom scale.Lazzini said:
You are correct, sir! My mistake!Lazzini said:
"Gravitation on an Expanded Earth" is a theory that suggests that the Earth's diameter has increased over time, resulting in a decrease in its gravitational pull.
The theory proposes that as the Earth expands, the distance between its center and its surface increases, causing a decrease in the Earth's gravitational pull.
One piece of evidence is the observation that the Earth's surface features, such as mountains and valleys, seem to fit together like puzzle pieces, suggesting that the Earth was once smaller and has since expanded. Additionally, the decreasing strength of the Earth's magnetic field over time supports the idea of a changing Earth.
If the theory is proven to be true, it would change our understanding of the Earth's history and geological processes. It would suggest that the Earth has undergone significant changes over time, including an expansion in size.
If the theory is correct, it could have implications for various fields such as geology, paleontology, and even astronomy. It could also lead to new discoveries and advancements in our understanding of the Earth and its history.
