From the Ted Talk by Rene Laufer: How far would you have to go to escape gravity?
Unscramble the Blue Letters
But when it comes to escaping gravity, there’s a loophole. If all the mass around us is pulling on us all the time, how would Earth’s gviatry change if you tunneled deep below the surface, assuming you could do so without being cooked or crushed? If you holeowld out the center of a perfectly spherical Earth— which it isn’t, but let’s just say it were— you’d experience an identical pull from all sides. And you’d be suspended, wgehitsles, only encountering the tiny pulls from other ctesaelil bodies. So you could escape the Earth’s gravity in such a thought experiment— but only by heading srihgtat into it.

But when it comes to escaping gravity, there’s a loophole. If all the mass around us is pulling on us all the time, how would Earth’s _______ change if you tunneled deep below the surface, assuming you could do so without being cooked or crushed? If you ________ out the center of a perfectly spherical Earth— which it isn’t, but let’s just say it were— you’d experience an identical pull from all sides. And you’d be suspended, __________, only encountering the tiny pulls from other _________ bodies. So you could escape the Earth’s gravity in such a thought experiment— but only by heading ________ into it.

But when it comes to escaping gravity, there’s a loophole. If all the mass around us is pulling on us all the time, how would Earth’s gravity change if you tunneled deep below the surface, assuming you could do so without being cooked or crushed? If you hollowed out the center of a perfectly spherical Earth— which it isn’t, but let’s just say it were— you’d experience an identical pull from all sides. And you’d be suspended, weightless, only encountering the tiny pulls from other celestial bodies. So you could escape the Earth’s gravity in such a thought experiment— but only by heading straight into it.
