Do black holes evaporate? What’s really happening at SpaceX? What is dark gravity? On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are answering fan-submitted Cosmic Queries covering topics all across the universe. To kick things off, Neil and Chuck investigate dark gravity and dark energy. Could dark energy be leftover energy from an evaporated black hole? We explore how black holes eventually disappear. Neil enlightens us about the “five ages of the universe.” We ponder if dark matter or dark energy could predate the universe itself. Neil tells us why galaxies are found where dark matter has collected them. You’ll hear why radio waves are the preferred contact method to chat with aliens. We dive into conspiracy theories and why humans are susceptible to believing in them. Discover more about “dark-sky ordinances” and how light pollution impacts telescopes. Neil shares an example of a city and observatory working together to create less light pollution. Are the sizes of planets proportional to the distance between planets? We discuss the gravitational influences of planets on each other. We also discuss how many light years you would have to travel in order to see the Roman battles taking place on Earth. If time is a coordinate, why can’t we move back and forth in time? We take a look at predeterminism. Lastly, we explore the science of Superman. What would happen if something made the Earth rotate in the opposite direction like in Superman. Neil reminisces on his star-turn in a Superman comic. All that, plus, you’ll learn how Neil found an actual home for Krypton. NOTE: StarTalk+ Patrons can watch or listen to this entire episode commercial-free.

Lesson 6 (Friction) of Dianna s Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you! Exercises in this video: Problem1: The coefficient of friction between your car’s tires and concrete is 0.7. Your car’s mass is 1000kg. If you slam on your brakes and the tires lock, what is the magnitude of the sliding friction force acting while you slide? What is your acceleration? Problem 2: You put your cow on a ramp. Moo. Then you tilt the ramp up, slowly. Just when your cow starts to slide, you measure the ramp angle as 34º. What is the coefficient of static friction between the cow and the ramp? Thank you to atrophysicist Naomi Rowe-Gurney for her awesome shoutout at the end of the video!

This documentary examines the enigma and the woman behind this aural assault on the public. Taking on the challenge of portraying the flamboyant ‘queen of dissonance’ is opera superstar Joyce DiDonato making her cinematic debut. The casting of a great opera singer in the title role makes it possible for the film to contrast two different musical worlds: the music Florence Foster Jenkins wanted to hear and claimed to make, melodious and masterful, and the reality of the sounds she subjected her audience to. It s like Netflix for history...
