This is why people in parts of Canada will always weigh LESS than anywhere else in the world

Perhaps the real secret to weight loss is moving to the tundra?

Around Canada’s Hudson Bay region, far to the northeast, researchers in the 1960s found that everything weighed just a little less,

In an area of ​​more than 500,000 square miles, you lose about 1/25,000 of your body weight.

Scientists first discovered this anomaly in the 1960s, when they first mapped variations in Earth’s gravitational fields. But it’s taken them decades to understand why.

Cause? Reduced molten magma beneath the region’s surface, squeezed out by above-ground pressure from two giant glaciers during the last ice age.

Many polar bears make their home around the icy streams and sandy shores of Hudson Bay. Each bear weighs just a little less, about 1/25,000 of what their weight would be in a zoo elsewhere

Let’s say you weighed 150 lbs. Near Hudson Bay, the shell would be about 149,994 lb.

The simple answer to this mystery begins with the fact that the gravitational force one object exerts on another is directly proportional to its mass.

But since an object entering Hudson Bay doesn’t necessarily lose mass on its way in, that doesn’t explain the mystery of Canada’s “missing” gravity.

To solve that, researchers turned to NASA’s twin Gravity Recovery and Climate Experiment (GRACE) satelliteswhich they used to map two gravity anomalies around Canada’s great saltwater bay in 2007 and how those anomalies change over time.

“The Canadian anomaly has been known for a long time and is the result of deformation of the Earth’s crust during the last ice age,” physicist Dan Britt, director of the Center for Lunar and Asteroid Surface Science at the University of Central Florida, told the DailyMail. nl by email.

At the time, about 20,000 years ago, Canada and much of North America lay in cold storage under the Laurentide Ice Sheet, a vast glacier about two miles thick in the regions near Hudson Bay.

“A few miles of ice is heavy enough to compress the crust,” said Britt, whose own work has occasionally involved refining lunar gravity models based on the geological differences between different types of moon rocks.

“The same process is happening in different places with thick ice sheets,” said Britt.

“The details have to do with the viscosity of the mantle.”

Under the crushing weight of the Laurentide Ice Sheet, the Earth’s crust around Hudson Bay began to compress and sink.

In the process, it displaced some of the hot magma in the semi-liquid mantle layer below, like a flattened sandwich pushing away peanut butter and jelly.

This compression was most severe on either side of Hudson Bay, where two giant domes had formed on the ice sheet.

The gradual recession of the Laurentide over the next 10,000 years accounted for many North American landmarks, including the Great Lakes.

Some theorists predicted that all that displaced molten mass had reduced Earth’s gravity around Hudson Bay — but NASA’s GRACE satellites showed that was only part of the story.

While the Laurentide Ice Sheet theory and data from GRACE explain some of the reasons gravity is lacking over Canada, they only explain about 25-45 percent of the gravitational difference.

Scientists estimate that the remaining 55-75 percent is due to a theory that has to do with conventions.

Far below the Earth’s surface, a slab of molten rock known as magma produces convection currents due to the natural rising and falling of the bubbling substance.

This drags in the continental plates of the Earth, causing a drop in the mass and gravity of the Hudson Bay area.

Gravity is expected to return to Canada, but gradually.

Geophysicist Mark Tamisiea of ​​the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, told the magazine Science that it will take up to 300,000 years for the gravity of the regions to equal the global average.
