How Gravity Shapes Our World With Jim Al-Khalili
Synopsis
A hammer and a feather dropped simultaneously on the moon in 1971 confirmed Galileo's theory that all objects fall at the same rate in a vacuum.

Synopsis
Professor Jim Al-Khalili stands at the LIGO lab in the United States, where scientists first detected gravitational waves. The film investigates how gravity influences everyday life, from weight and height to the aging process. Al-Khalili conducts experiments to demonstrate fundamental principles, such as why a hammer falls faster than a feather. He also delves into historical insights from figures like Galileo Galilei, ultimately questioning the relationship between gravity and the flow of time.
Deep Dive
Why Watch
- Find out how gravity shapes your weight and height.
- See Galileo's experiments proven on the moon.
- Discover the link between gravity and the flow of time.
Did You Know
- Galileo Galilei first demonstrated that objects fall at the same rate in the 16th century.
- In 1971, an experiment on the moon confirmed Galileo's findings about falling objects.
- At high altitude, the difference in the rate of flow of time is one second in 100 years.
- Gravity affects how we age at different rates, as shown through volunteer participation.

Frequently Asked Questions
Why does a hammer fall faster than a feather?
A hammer falls faster than a feather due to air resistance, not because of its weight.
Who first realized that all objects fall at the same rate in a vacuum?
Galileo Galilei first realized that all objects fall at the same rate if air resistance is removed.
What is the difference in the rate of flow of time at high altitude compared to the surface of the Earth?
The difference in the rate of flow of time is one second in 100 years between high altitude and the surface of the Earth.
