  • Where did supermassive black holes come from?
    The answer is different than we once thought.
    Based on observations from our observatories, we now have evidence that supermassive black holes may have formed from a process known as direct collapse.
    In direct collapse, huge clouds or streams of gas collapse to make seed black holes, maybe even before the galaxies that we associate them with are created.

  • Ben Horowitz: Quit being a coward and do the hard thing | Big Think+
    "You need to run towards the pain and darkness and not away from it. I think the best leaders always run towards the darkness. They always run towards a problem."

    Up next, The smartest people have mastered these 6 core skills ► https://www.youtube.com/watch?v=32z8Ax1j-Q4
    Much of the management advice we find in books emphasizes using leadership tactics that may seem reasonably obvious. This advice is often easy to follow — but that’s not where leaders run into issues with their strategy, argues Ben Horowitz, founding partner at the venture capital firm Andreessen Horowitz and author of the best-selling book, "The Hard Thing About Hard Things.”
    Horowitz says that leaders make blunders when they find themselves in highly emotionally charged situations where the emotion prevents them from doing the thing that they intellectually know they need to do. For example, firing a friend or doing a reorganization that causes a very talented employee to lose power. These things are much more difficult, and people often avoid them. But as a leader, you're much better off running at your fear than running away from your fear because it's going to chase you down, emphasizes Horowitz.
    ‘Management debt’ is what happens when you don't do what you're supposed to. And accruing a lot of management debt has a cascading effect that can create a total degradation of your organization. Here’s how to lead instead.

    1:19: Management debt
    2:42: Wartime conditions

    Alua Arthur, a death doula, never expected to find her calling in the space between life and death. Struggling with depression and a sense of not belonging, she was searching for meaning when a chance encounter in Cuba changed everything.
    After encountering death in her personal life, she began to confront her own mortality—and realize she wasn’t truly living. This moment, combined with the loss of her brother-in-law, set her on a path to becoming a death doula, someone who supports people through their final days. Now, she is an author, a (public speaker), and has dedicated her career to helping others embrace life by acknowledging its inevitable end.

  • How will the Universe end?
    One day, the Universe will go completely dark. No more stars. No more light. Just a cold, endless equilibrium where energy can no longer be extracted.
    This is known as the “Heat Death of the Universe.”
    What will the universe’s last flicker of energy be? Dr. Ethan Siegel breaks down two possible final acts of the cosmos:
    Corpses of stars spiraling into each other, emitting their last gravitational waves.
    Supermassive black holes slowly decay over time until the last one releases one final flash of energy that propagates throughout the Universe at the speed of light.

  • How I traded perfection for peace | Gracie Gold

    Gracie Gold’s battle with mental health nearly ended her career—and her life. This is how she found her way back to herself.

    Gracie Gold, a two-time national champion and Olympic medalist, seemed to embody perfection. But behind the medals and the headlines, her obsession with being flawless led her to a breaking point. After the 2016 World Championships, she spiraled into depression, binge-eating, and a complete loss of identity.
    Feeling trapped and out of place, Gold hit rock bottom before seeking help at a treatment facility. There, she finally “met herself,” learning to let go of perfection and accepting “okay” as enough. Now, she’s a mental health advocate and a New York Times bestselling author.

    What if the world's most critical technology isn't software, but the tiny pieces of silicon that power it? In an age where chips are everywhere, from smartphones to coffee makers, their manufacturing complexity might surprise you. It's harder to make a modern semiconductor than a nuclear weapon.
    Inside Taiwan's cutting-edge fabrication plants, machines worth $350 million each orchestrate an atomic ballet. These marvels of engineering use the flattest mirrors ever made and lasers that create temperatures 40 times hotter than the sun's surface – all to carve transistors smaller than a coronavirus.
    From Silicon Valley to Taiwan, from the Netherlands to Japan, making modern chips is a global dance of unprecedented complexity. Each processor requires ultra-purified materials, billion-dollar machines, and a supply chain spanning multiple continents. But this intricate network faces its greatest challenge yet.
    As artificial intelligence reshapes our world, the demand for advanced chips is skyrocketing. Tech giants are pouring billions into new semiconductor designs, while startups race to create specialized AI chips that could make artificial intelligence as accessible as a Google search. Join us as we explore how these tiny silicon marvels are shaping humanity's future.
