The Mysterious Hudson Bay: A Place Where Gravity is Weaker

Home » The Mysterious Hudson Bay: A Place Where Gravity is Weaker

Canada is known for its unique geography and diverse wildlife. However, not many people know there is a place in Canada where gravity is weaker than in the rest of the world. This mysterious location is in Hudson Bay, an Arctic body of water that has puzzled scientists for decades.

Fact: It is very interesting to note that an area in Hudson Bay has less gravity than the rest of the world.

  1. The area in Hudson Bay, known as the Hudson Bay Lowlands, has less gravity than other places on Earth. It was first discovered in the 1960s by a team of geophysicists who were studying the area.
  2. The weaker gravity is still unknown, but scientists believe it may be due to the rebound of the Earth’s crust after the last ice age. The weight of the ice caused the Earth’s crust to depress, and after the ice melted, the crust began to rebound. This rebound may have caused the area in Hudson Bay to have less gravity.
  3. The weaker gravity in Hudson Bay has a measurable effect on satellites that pass over the area. Satellites in polar orbits experience a slight decrease in speed and a change in trajectory when passing over the Hudson Bay Lowlands.
  4. Despite the weaker gravity, the Hudson Bay Lowlands is not a place where you can float away. The difference in gravity is only about 0.005 percent, which is not noticeable to humans.

Did you know about Hudson Bay?

Hudson Bay is a massive body of saltwater located in northeastern Canada. It is the second-largest bay in the world, with an area of approximately 1.23 million square kilometers. The bay is named after the famous explorer Henry Hudson, who discovered it in 1610 while searching for a northwest passage to Asia. Hudson Bay has a unique geography, surrounded by low-lying land covered in forest, tundra, and muskeg. The bay also has diverse wildlife, including polar bears, beluga whales, and arctic foxes.

In addition to its natural beauty and ecological significance, Hudson Bay has played an essential role in Canada’s history. The Hudson’s Bay Company, one of the oldest commercial enterprises in the world, was established in 1670 as a fur trading business. The company became the dominant force in the Canadian fur trade and was instrumental in the exploration and settlement of the Canadian West. Today, the Hudson’s Bay Company is a major retailer in Canada and continues to symbolize Canadian heritage and tradition.


The mystery of the weaker gravity in Hudson Bay is still unsolved, but it adds to the fascinating geological features of Canada. It is a reminder that there is still so much we don’t know about our planet and that exploration and scientific discovery will continue to uncover new and unique facts.
