36 I just watched a live video of Earth from space, courtesy of NASA. How come you can’t see it spinning at 1,000 mph?

37 I read that if gravity on Earth were 10% more, blasting off into space would be practically impossible. Does this mean that, once we fly into the gravity well of a more massive planet like Jupiter, we can never escape?

38 Would spaghettification hurt?

39 Why can't Mars hold onto water even if we managed to give it a lot, like from Europa? What's the science behind it?

53 Why do you think some scientists think there is life on Enceladus, another of Saturn's moons, and why hasn't NASA sent a probe?

54 Do scientists suspect that there are undiscovered elements in the solar system? If scientists are sure that there aren’t any, how can they be so sure?

55 What is the myth behind standing brooms and the Earth’s tilt?

56 If a black hole is the size of a grain of sand, would it still be considered a black hole?

57 Is the moon's soil as fertile as Earth's soil?

58 If a plane flies west fast enough, could it technically “chase the sunset” and keep it from getting dark?

59 What galaxy do you think is the most interesting?
