![]() Origins is the companion book to the PBS NOVA four-part mini-series Origins, in which Tyson served as on-camera host. And among Tyson’s fifteen books is his memoir The Sky is Not the Limit: Adventures of an Urban Astrophysicist and Origins: Fourteen Billion Years of Cosmic Evolution, co-written with Donald Goldsmith. From 1995 to 2005, Tyson was a monthly essayist for Natural History magazine under the title Universe. Tyson has written, and continues to write for the public. In addition to dozens of professional publications, Dr. And in 2006, the head of NASA appointed Tyson to serve on its prestigious Advisory Council, which guides NASA through its perennial need to fit ambitious visions into restricted budgets. This group navigated a path by which the new space vision can become a successful part of the American agenda. In 2004, Tyson was once again appointed by President Bush to serve on a nine-member commission on the Implementation of the United States Space Exploration Policy, dubbed the “Moon, Mars, and Beyond” commission. The final report was published in 2002 and contained recommendations (for Congress and for the major agencies of the government) that would promote a thriving future of transportation, space exploration, and national security. In 2001, Tyson was appointed by President Bush to serve on a twelve-member commission that studied the Future of the U.S. Tyson went on to earn his BA in Physics from Harvard and his PhD in Astrophysics from Columbia. What do you think? If you could drop anything into a black hole, what would it be? Tell us in the comments below.Neil deGrasse Tyson was born and raised in New York City where he was educated in the public schools clear through his graduation from the Bronx High School of Science. Would you still be totally screwed? YOU BETCHA! So if you happened to be near a supermassive black hole, you could cross the event horizon without really noticing. In fact, the larger the black hole, the weaker the tidal forces near its event horizon. For a solar mass black hole, the tidal forces near the event horizon can be quite large, but for a supermassive black hole they aren't very large at all. Unfortunately, this goes along with those who suspect black holes are actually some sort of portal. Many people think that it is at the event horizon where you would be ripped apart, and at the event horizon all sorts of strange things occur. The sky would simply appear more and more black until you reach the event horizon. What you would see is the darkness of the black hole fill your view and as you approached the event horizon you would see stars and galaxies on the edge of your view being gravitationally lensed by the black hole.

This effect of tidal stretching is sometimes boringly referred to as spaghettification. ![]() Eventually the tidal forces would become so strong that they would rip you apart. Because of the tidal forces it would feel as if you are being stretched head to toe, while your sides would feel like they are being pushed inward. These differences in forces are called tidal forces. As you got closer, your feet would feel a stronger force than your head, for example. Suppose you were falling feet first toward a black hole. Technically this is always true, but you wouldn't notice it… at least at first. As you get closer, the gravitational forces on various parts of your and your dragon's body would be different. But, as we've agreed, you're ignoring my advice and flying dragon first into this physics nightmare. ![]() The gravity of a black hole is just like the gravity of any other large mass, as long as you don't get too close. If you were falling toward a black hole, most of the time you would simply feel weightless, just as if you were playing Bowie songs and floating in a most peculiar way in the International Space Station. ![]() We know it won't take you to another world or galaxy, but what would you experience and see on your way to your inevitable demise? And what would the rest of the Universe see as this was happening, and would they point and say "eewwwwww"? ![]()
