Bears are known as the world’s most hardy animals. They can survive without water for years, freezing to minus 272 degrees, heating to 151 degrees, 1000 times greater doses of radioactivity than humans, as well as vacuum and pressure that is 6000 times greater than on land, writes Illustrated Science.
But even though they are apparently invulnerable, bears’ endurance also has a limit. Researchers fired containers of bears through a high-speed gun to see how much pressure they could withstand, according to Business Insider.

The tests showed that the bears could be awakened to life after being shot out at a speed of 2,000 miles per hour, equivalent to just over 3,200 kilometers per hour, but that collisions after speeds above this became too much for them. This is explained by Alejandra Traspas, astrochemist at Queen Mary University in London, to the website. The pressure experienced by collisions at 3200 kilometers per hour can also be compared to 40,000 people standing on your back – at the same time.
– But they could not stand more than that. Then they just became a moss, says Traspas Science.

Facts about bears:
- Bears are small, microscopic animals, 0.2 – 0.8 mm long, the largest up to 2 mm long. They have a shape reminiscent of a bear. Found on land in bogs, lichen and soil, and in sediments in fresh and salt water. They are widespread throughout the world, including Antarctica, and are known for their survivability. Bears form a separate series in the animal kingdom.
- Bears have lived on earth since Carbon more than 520 million years ago. They share this with velvet animals, with which they are also distantly related.
- It is known approx. 1100 species worldwide. Some species live in the ocean, where they sit between grains of sand at different depths. Under Norwegian conditions, according to the Species Data Bank as of 2016, 25 species have been found in freshwater, 104 terrestrial species in moist vegetation, and 7 marine species, but it is believed that more have not been discovered. Among the most extreme places to find bears are meltwater holes on glaciers.
