Description: Every star, black hole, human being, smartphone and atom are all constantly pulling on each other due to one force: gravity. So why don't we feel pulled in billions of different directions? And is there anywhere in the universe where we'd be free of its pull? Rene Laufer details the inescapability of gravity. [Directed by TED-Ed, narrated by Addison Anderson].

How far would you have to go to escape gravity?

Every star, black hole, human being, smartphone and atom are all constantly pulling on each other due to one force: gravity. So why don't we feel pulled in billions of different directions? And is there anywhere in the universe where we'd be free of its pull? Rene Laufer details the inescapability of gravity. [Directed by TED-Ed, narrated by Addison Anderson].

Gravity connects every object in the universe, from stars and black holes to smartphones and atoms. Even 400 kilometers above Earth, astronauts still feel ninety percent of gravity’s pull. No matter how far someone travels, Earth’s gravitational influence never truly vanishes, only weakening with distance. The only place a person could escape this force altogether would be at the exact center of a perfectly hollow Earth, suspended between equal tugs from all sides.
