If Earths gravity had doubled since the time of the sauropods we would expect the opposite effect. Scientists understand that Earths magnetic field has flipped its polarity many times over the millennia.

Mount Nevado Huascarán in Peru has the lowest gravitational acceleration at 97639 ms 2 while the highest is at the surface of the Arctic Ocean at 98337 ms 2.
Has earth's gravity changed. But its true. These changes in the local gravity field can be tracked as the time-variable gravity field over periods of years including the following. During its four-year run GOCE was able to make a number of observations that showed gravity changes over time including the gravity scar left by the 2011.
They used magnetic field measurements of the GFZ-satellite CHAMP and extremely accurate measurements of the Earths gravity field derived from the GRACE mission which is also under the auspices of the GFZ. Regions like Alaska and the Himalayas have experienced the most. Earths gravityas with any planet star moon asteroid etcis determined primary by its mass and size.
Melting glaciers and overuse of groundwater account for much of the change. Logically either some of the experiments are wrong or G is not constant says Mark Kasevich of Stanford. Our best clues about the interior come from waves that pass through the Earths material.
GRACE detects tiny changes in gravity over time. The gravitational force above the Earths surface is proportional to 1R 2 where R is your distance from the center of the Earth. Earths gravitational field the 3D representation of the planets gravitational influence is not a uniform sphere.
The Moon is actually moving away from Earth albeit very slowly. In order for us to get some understanding of how the earth has changed over time we first need to understand some of the things that took place and are still taking place in the earth. In other words if you were alive about 800000 years ago and facing what we call north with a magnetic compass in your hand the needle would point to south This is because a magnetic compass is calibrated based on Earths poles.
This means according to EU theory that electric gravity can change. But the latest result could also be evidence that gravity itself may be changing. In fact theres another sign Earths gravity hasnt changed much in the last 100 million years.
If you wanted to make gravity noticeably stronger youd have to add the equivalent mass of another planet or moon something that. Earths gravity is indeed changed by both of these factors. Second gravity does indeed change with altitude.
Earths axis has shifted due to climate change. Because water in all its forms has mass and weight we can actually weigh the ocean moving around. We can weigh rainfall and we can weigh changes in the polar ice caps This diagram illustrates the hydrologic cycle and shows how water circulates over.
Nevado was a bit surprising. NASAUniversity of Texas Center for Space Research. The radius of the Earth at the equator is 6378 kilometers so lets say you were on a mountain at the equator that was 5 kilometers high around 16400 feet.
So really any change to the strength of gravity or any change to the masses of the objects involved would change the distance between the Earth and the Sun. Mass is roughly speaking the amount of matter in the planet and thats something hard to change drastically. What about the internal structure of the Earth.
The Earths gravity field changes from one month to the next mostly due to the mass of water moving around on the surface said Watkins. The Electric Universe theory suggests that the mystery of what gravity actually is may be an electromagnetic force. The research group has now succeeded to provide the first evidence of such a connection of fluctuations in the Earths gravity and magnetic field.
When the two satellites burned up in the Earths atmosphere at the end of 2017 and beginning of 2018 they had recorded the Earths gravitational field and its. Today gravitational waves reality has been established convincingly by indirect methods and experiments to detect them directly are under way see Magnifying the Cosmos. A new analysis of satellite data has shown that the strength of Earths gravity changed after the 2011 earthquake in Japan.
Earths gravitational field is constantly shifting because its dynamic surface processes cause local changes in mass that occur on shorter time scales. Areas in blue have slightly weaker gravity and areas in red have slightly stronger gravity. If gravity is due to some electrical force then the weight of animals on the planet could vary so you could get mega and micro fauna and flora including dinosaurs.
The GRACE mission helps scientists to create maps of gravity variations on Earth.
