Context: After a tough win over the Texans, the Steelers stayed home for a game against the Colts. In the first quarter, the Colts scored first as Adam Vinatieri nailed a 31-yard field goal for a 3-0 lead. However, the Steelers took the lead later on in the quarter when Ben Roethlisberger found Markus Wheaton on an 18-yard TD pass for a 7-3 game. In the 2nd quarter, the Steelers would score again increasing their lead as Roethlisberger found Martavis Bryant on a 5-yard TD pass for a 14-3 game. This was followed by William Gay picking off Andrew Luck and returning it 33 yards for a TD as they increased their lead to 21-3. The Colts however responded as Andrew Luck threw a 21-yard TD pass to Dwayne Allen for a 21-10 game. However, the Steelers pulled away as Roethlisberger would find Antonio Brown on 2 consecutive TD passes: from 8 and 47 yards out to increase their lead at first from 28-10 to 35-10. The Colts responded with 10 straight points first being Luck who found T. Y. Hilton on a 28-yard TD Pass for a 35-17 game followed by Vinatieri kicking a 23-yard field goal before halftime to make the score 35-20. The Steelers went back to work in the 3rd quarter as Roethlisberger and Bryant hooked up again on a 2-yard TD pass to increase their lead making the score 42-20. The Colts however were able to come within 8 later on when Ahmad Bradshaw ran for a 12-yard TD followed by Luck finding Donte Moncrief on a 31-yard TD pass to make the score 42-27 and then 42-34. In the 4th quarter, it was all Steelers when a penalty was enforced on Luck in the end zone for a safety making the score 44-34. The Steelers were able to seal the game later on when Roethlisberger found Heath Miller on an 11-yard TD pass for a final score of 51-34. Roethlisberger set franchise records with 522 yards passing and six touchdowns while picking up his 100th victory in his 150th start. Roethlisberger's yardage total was the fourth highest in NFL history. He became the first player in NFL history to go over 500 yards passing twice as the Steelers won consecutive games for the first time this season.

Context: Think about the longest elevator ride that you've ever taken. Whether you rose five or 100 floors, it probably took less than a few minutes. Now imagine riding in an elevator higher and higher as it climbs for nearly a day. When you reach the top floor, prepare for views that are really out of this world. You'll be in space! Space elevators might sound like a crazy idea, but they're something scientists have been working on for decades. At the moment, riding in a capsule is the only way ordinary people can get to and from space. But those rides are very expensive---about $ 25 million per person per flight. Now scientists are making efforts to reduce the expense of those rides. Researchers are still figuring out the details about how a space elevator might work. One idea is stretching a very long cable -- more than 37,000 kilometers -- up to space from the earth's equator . Objects in space above the equator orbit (......) the earth at the same speed that our planet turns. A weight on the end of the cable would stretch it tight. An elevator tied to the cable could use _ to climb up and down. The only problem is that besides being long, this cable must also be very strong. Storms, including hurricanes might break it. One way to solve this problem is to stretch the cable from the moon instead of from the earth. Airplanes designed to climb higher than a typical jet might take off from the earth and link up with the cable, which would be held in place by the pull of gravity from the earth. An elevator car waiting there would then take riders the rest of the way to the moon. Fueled by solar power, the elevator could transport people and materials without much expense or effort per ride. 
 Question: What may make the cable stay in place on the moon?
answer:

the pull of gravity from the earth.
