0:00.0 | Understanding the human body is a team effort. That's where the Yachtel group comes in. |
0:05.8 | Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years. |
0:11.0 | Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program. |
0:19.6 | To learn more about Yachtolt, visit yawcult.co. |
0:22.7 | J-P. That's Y-A-K-U-L-T.C-O.J-P. When it comes to a guide for your gut, count on Yacolt. |
0:33.7 | This is Scientific American's 60-second science.'m Christopher in Taliatta. Got a minute? |
0:39.9 | Black holes are not all created equal. There are the regular star-sized ones, and then the supermassive black holes, which really live up to their name. |
0:49.2 | So the Milky Way has a supermassive black hole sitting at the center, weighing upwards of four million times the mass |
0:56.3 | of the sun. They're monsters. Jesse Rogerson, an astrophysicist at York University in Toronto. |
1:02.2 | Rodgerson studies the sites of the most violent, most active supermassive black holes, |
1:07.0 | quasars. They're pretty much some of the most extreme things you'll find in the universe. |
1:11.4 | The black holes at the centers of quasars gobble up massive amounts of gas and dust. |
1:15.8 | And that heat, that radiation that's created from the falling in, it actually turns itself |
1:21.4 | into a disk of stuff falling in. |
1:23.5 | So it's kind of like circling the drain almost. |
1:26.4 | And that accretion disc, that's, |
1:27.9 | that disc of stuff is so bright, it can outshine the entire galaxy within which it resides. |
1:33.9 | That disc isn't just bright. It's also blazing hot. And that intense heat creates winds. |
1:40.2 | Think of a massive hairdriar, like the size of our solar system, blowing away galactic gas and debris. |
1:46.5 | Rodgerson and his colleagues aimed the Gemini Observatory on one such quasar, called J.O.230, about 11 billion light years away. |
1:55.3 | And they tracked a cloud of gas, blowing away from J.O.230, and clocked the speed at 135 million miles per hour. |
2:03.8 | That's a fifth the speed of light. |
