quantumclaustrophobe say: But... there *is* gravity in outer space. Every mass has gravity. You do. The book on your shelf does. So does the Earth, and the moon.
-
Roger K say: There is gravity EVERYWHERE, and the moon has a gravitational field of its own. It is 1/6 the strength of that of the earth, but it is sufficient for the astronauts to be able to walk around, ride the lunar rover and do all the needed activities during their stay.
There is NO argument about the 6 manned landings on the moon. They are FACT, and I mean real facts, not alternative ones. The competition was with the Soviet Union, not China, and if any part of the missions were fakes, teh USSR wold have figured it out.
-
Joan H say: To correct your other misconception, it was competition with the Soviet Union that led to our need to land on the moon first. Nothing to do with China.
-
Kirk say: Using the weak nuclear force obviously. Gravity isn't the only one. They developed a type slow decaying. You know what let us just say magic they used real true to life magic! Feel special now?
-
JG say: That's not necessarily true- the gravity on the moon is about 1/6 that of the Earth- gravity on the moon is 1.622 m/s².
-
Bill say: There IS gravity in space. Try getting an education.
-
spot a say: Gravity from every particle of matter extends to the edge of the universe (if it has an edge). Gravity requires TWO masses to interact. Nobody bothers calculating gravity on earth with the mas of a human because they are so lignt compared to the earth. Even so, if your mass didn't interact with the mass of the earth according to Newtons G*M1*M2/(R^2) formula where M2 is your mass and R is the radius of the earth, you would float off into space
-
Infinitely Certain say: The moon has comparatively weak gravity compared to the earth but it's still strong enough to hold a human down. This is exactly why on the moon you can jump higher than you can on earth.
