For the past 23 years Andrea Ghez, professor of physics and astronomy at UCLA, has been collecting data on stars that orbit black holes. She found that their motion provided an opportunity to test the fundamental laws of physics. “We asked how gravity behaves near a supermassive black hole and whether Einstein’s theory is telling us the full story. ”Einstein’s 1915 theory of general relativity holds that what we perceive as the force of gravity arises from the curvature of space and time. “In Newton’s version of gravity, space and time are separate, and do not co-mingle; under Einstein, they get completely co-mingled near a black hole,” she said. Ghez's research is the most detailed study ever conducted into the supermassive black hole and Einstein’s theory of general relativity. ➡ Subscribe: http://bit.ly/NatGeoSubscribe ➡ Get More Short Film Showcase: http://bit.ly/ShortFilmShowcase About Short Film Showcase: The Short Film Showcase spotlights exceptional short videos created by filmmakers from around the web and selected by National Geographic editors.

In this episode we witness one of the Arctic’s most magical moments. With the help of a one-of-a-kind local tracker, we find a female polar bear fresh out of her winter den with her tiny new cub. We see ultimate cuteness as the cub explores the world outside for the first time. Their irresistible interactions distract from the fact that the mother bear is actually making an impossible decision. The mother has spent the last eight months starving, so she is eager to rush to the ocean where she can hunt. But to reach the seal feast means a 40-mile trek. Does she wait to allow the cub to gain strength for the long trek, or does she head out to sea to make sure her milk doesn’t dry up? We also follow a young female bear in her first moments of independence, having been kicked out by her mother. She has spent the last two and a half years with her mother preparing for this moment, but she quickly manages to get herself into trouble. Will she be able to survive a wolf on the hunt? ➡ Subscribe: http://bit.ly/NatGeoSubscribe #NationalGeographic #BertieGregory #WildlifeTheBigFreeze About National Geographic: National Geographic is the world's premium destination for science, exploration, and adventure.

Polar bears dominate the Arctic animal headlines; it’s hard for anything to escape their shadow. In this episode we meet an unexpected array of smaller species that each have their own peculiar but no less entertaining strategies for surviving in this brutal environment. The tiny arctic fox might look cute, but it’s actually a killing machine. The arctic hare may be fluffy and have comical ears, but it’s both a master of camouflage and one of the fastest animals here. The snowy owl has sacrificed speed for a mightier secret weapon: silence. We find a lemming (a tiny brown rodent) running around in a blizzard, a big mistake when silent assassins are flying overhead. Although these unsung heroes are some of the few who’ve perfectly adapted to this place, the environment is changing fast. Warming temperatures are allowing enemies to move north, encroaching on these Arctic specialists. ➡ Subscribe: http://bit.ly/NatGeoSubscribe #NationalGeographic #BertieGregory #WildlifeTheBigFreeze About National Geographic: National Geographic is the world's premium destination for science, exploration, and adventure.

While both dogs and pigs can communicate with their human counterparts, pigs are more likely to engage when food is involved. ➡ Subscribe: http://bit.ly/NatGeoSubscribe About National Geographic: National Geographic is the world's premium destination for science, exploration, and adventure.

But little is known about how pigs communicate with humans. In a new study, researchers at Eötvös Loránd University in Budapest looked at how highly socialized young pigs and puppies spontaneously interact with humans. In essence, they wanted to compare the natural inclination for companionship in pet pigs. In this test, the experimenter gave the four-month-old pig and four-month-old dog food every two minutes. Both the dog and pig looked at the trial runner’s face during the tests where food was distributed. However, when the food was withdrawn from the experiment, only the dog continued to look up at the experimenter’s face. The pig decided to do other things. In another test, experimenters would point to a bowl of food and see how the untrained animals responded to their gesturing. The untrained puppy naturally followed the pointing of the experimenter. But the untrained pig went to the same bowl regardless of where the experimenter was gesturing. The results of these tests, however, speak beyond the findings that dogs are naturally more responsive pets than pigs. Since both animals are incredibly intelligent, the behaviors may speak more to their evolutionary history with humans. Dogs have been domesticated for more than 15,000 years, while pigs have been domesticated for less than 10,000. Historically dogs have been used to work with humans while pigs mainly for meat production. These stark historical differences affect the way pigs and dogs respond to humans from a young age. Pet pigs have become popular in the last few decades, especially with the appeal of small-breed pigs. But often owners are misled and end up with pigs that grow to be much bigger than expected. Experts advise potential owners to be fully informed about the responsibility and risks associated with pet pigs.
