剧情介绍
Physics professor Jim Al-Khalili investigates the amazing science of gravity. A fundamental force of nature, gravity shapes our entire universe, sculpting galaxies and warping space and time. But gravity's strange powers, discovered by Albert Einstein, also affect our daily lives in the most unexpected ways. As Jim tells the story of gravity, it challenges his own understanding of the nature of reality.
The science of gravity includes the greatest advances in physics, and Jim recreates groundbreaking experiments in gravity including when the Italian genius Galileo first worked out how to measure it.
Gravity science is still full of surprises and Jim investigates the latest breakthrough - 'gravity waves' - ripples in the vast emptiness of space. He also finds out from astronauts what it's like to live without gravity.
But gravity also directly affects all of us very personally - making a difference to our weight, height, posture and even the rate at which we age. With the help of volunteers and scientists, Jim sets out to find where in Britain gravity is weakest and so where we weigh the least. He also helps design a smartphone app that volunteers use to demonstrate how gravity affects time and makes us age at slightly different rates.
And finally, Jim discovers that despite incredible progress, gravity has many secrets.

讲述人类发现重力本质的过程。前半段讲初中的牛顿力学,伽利略实验,简而美的万有引力定律。后半段讲爱因斯坦小宇宙爆发指出重力不是力,而是质量造成时空弯曲,你们是三维低速生物当然没这脑洞。最后LIGO窜场,基普·索恩带着主角光环指出,万物都喜欢去时间流逝最慢之地,由重力操刀把你拉到那里。
