Q0fwRMvNkoA sabine-gravity-without-mass-could-explain-dark-matter Sabine | Gravity Without Mass Could Explain Dark Matter I recently read that you can have gravity without mass. Ha, no way, I thought and had a look at the paper. It's wild, people. -ZRwlYtAMps killer-patents-secret-science-free-energy-anti-gravity-cover-ups Killer Patents and Secret Science | Free Energy and Anti-Gravity For decades, we've heard about the catastrophic effects of fossil fuel pollution. For just as long, I've been hearing that global warming is a myth. ALmS9E87LCg pbs-space-time-does-antimatter-create-anti-gravity PBS Space Time | Does Antimatter Create Anti-Gravity? From hoverboards to flying cars to cloud cities, anti-gravity is a staple of science fiction and our dream of a less Earth-bound future. But in the real universe gravity appears to be a purely attractive force. HlNSvrYygRc dr-becky-huge-blow-for-alternate-theory-of-gravity-mond Dr. Becky | Huge blow for alternate theory of gravity MOND A new research study was published this month claiming to have completely ruled out an alternate theory of gravity called MOND, that doesn’t need dark matter to explain our observations of the Universe. eIgbsZ05O2A gravity-is-a-lie-light-speed-is-slow-nothing-is-real Gravity is a Lie | Light Speed is Slow | Nothing is Real Since grade school, we’ve been taught that gravity is what keeps our feet firmly planted on the ground, but what if that’s all been a lie? DkRbNXILroI quanta-magazine-a-bet-against-quantum-gravity Quanta Magazine | A Bet Against Quantum Gravity Is gravity quantum in nature, just like all the other particles and forces? Or is it fundamentally different? For nearly a century, physicists have attempted to define gravity using the framework of quantum mechanics. But it turns out that “quantizing” gravity leads to some thorny dead ends. Q0CE7qDQYpA discovery-of-new-gravity-waves-is-going-to-rewrite-physics Discovery of New Gravity Waves is Going to Rewrite Physics Astronomers have finally discovered the gravitational-wave background, the faint hum of the cosmos. zpXGN6BKTBU how-goats-defy-the-laws-of-gravity How Goats Defy the Laws of Gravity Nature has thought of everything down to the smallest detail when making her creations. It endowed animals with unique abilities that help them survive in their habitat. Ygq-DK1p17E is-the-strength-of-gravity-really-constant Is the Strength of Gravity really Constant? Is the gravitational constant, G, really a constant? Or does it change with time, or with space, or with scale in the Universe?! And if it did, could this help solve the crisis in cosmology?! Or even be an explanation for dark energy and the accelerated expansion of the universe? XRr1kaXKBsU veritasium-is-gravity-an-illusion Veritasium | Is Gravity an Illusion? The General Theory of Relativity tells us gravity is not a force, gravitational fields don't exist. Objects tend to move on straight paths through curved spacetime. d-86tNCSJsg quantum-gravity-the-search-for-a-theory-of-everything Quantum Gravity | The Search for a Theory of Everything Why don’t we have a theory of quantum gravity yet? I explore why it has been so difficult. wYDJ0vxg1lU is-artificial-gravity-really-achievable Is Artificial Gravity Really Achievable? Rotating habitats and artificial gravity are a staple of science fiction movies and TV shows, but the realities of space travel means that someday we'll have to get serious about artificial gravity to keep our astronauts and space travelers healthy. The question is, what's the best way to do that, and is it even possible with today's technology? fUj1-cPaFgo microgravity-will-change-how-we-make-everything Microgravity will change how we make everything Microgravity can be used to unlock old materials and make new ones in ways that can’t be replicated on Earth. Private companies know this, and are leading the charge toward the next gold rush. But can they turn low Earth orbit into a home for the next ind b3D7QlMVa5s cool-worlds-artificial-gravity Cool Worlds | Artificial Gravity Artificial gravity is a concept that is ubiquitous in our science fiction yet elusive in our space program. Why is this? And how could we develop artificial gravity soon? 2_p2ELD7npw jim-al-khalili-the-amazing-world-of-gravity Jim Al-Khalili | The Amazing World of Gravity From the award-winning team that brought you The Secret Life of Chaos comes a unique television event on the physics of gravity, featuring unexpected historical insights, cutting- edge science and exciting new experiments.
