Host Anand Jagatia tackles gravity - a fundamental force of the universe yet also an everyday mystery that has baffled several listeners. Can you outrun it? Or at least use it to get fitter? If it varies, does that mean that you weigh less, depending on where on earth you stand? And if it’s the force of attraction between any objects with mass, are you technically more attractive after eating a massive cake? Professor Claudia de Rham from Imperial College London explains the basics of gravity, while we discover the best place on earth to weight ourselves, with Professor Paddy Regan from Surrey University and NPL Fellow in Nuclear and Radiation Science and Metrology. Anand takes a very fast spin on a special chair to experience extra gravity, thanks to Professor Floris Wuyts from the University of Antwerp, Kings College London and Minister of Science of Asgardia. And finally, we talk to an expert lined up at the other end of a hypothetical hole through the earth: Professor Richard Easther from the University of Auckland, New Zealand. What would happen if we fell straight through the earth? CrowdScience finds gravity a force to be reckoned with.

  • Is it totally dark now?

  • Yes, it's totally dark now.

  • Okay, now you're spinning at 350 degrees per second.

  • This really does feel like being on some kind of space mission.

  • Can you do A this is CrowdScience thing?

  • Yes.

  • Hello, this is CrowdScience from the BBC World Service.

  • I'm Anand Jagatia and currently experiencing extra gravity.

  • I'm strapped into a chair that is spinning very, very fast in an absolutely pitch dark room.

  • And the reason why I'm spinning so fast in this chair is because of a listener question all about gravity.

  • And I say a listener.

  • But the CrowdScience inbox is groaning from the weight of messages about this mysterious force,

  • gravity.

  • So in this episode we're going to tackle some of them.

  • We'll be returning a bit later to that spinning chair where I experienced extra G force.

  • But in the rest of this gravity special, we will be looking at a physicist guide to weight loss,

  • how gravity could help make astronauts and the rest of us super fit.

  • And we'll be traveling to the other side of the world really fast.

  • As you can hear, we're not in the studio today.

  • We're at my house in England and I should say I'm joined by Marnie Chesterton,
