19 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?

20 Would spaghettification hurt?

21 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?

22 Why do scientists say that the universe is flat?

23 Is it possible that if a black hole becomes massive enough, it can turn into something else?

24 If there was a black hole the size of 1 millimeter on Earth, what would happen?

25 What is an example of how large the universe is that will truly blow my mind?

26 Do British people know what the Sun looks like?

27 In the Flat Earth Society beliefs, are the other planets flat too?

28 What are the most common arguments from people who believe the earth is flat?

29 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?

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

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

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

33 Can the confirmation of flight times between 2 different pairs of places verify that the Earth is flat?

34 What is the silliest argument you've heard in favor of the flat Earth theory?

35 How do you obviously debunk the flat Earth theory? Why are their beliefs impossible nonsense?

36 As it's estimated that it will take 110000 years to reach Alpha Centauri, does it mean that there's a life secret, which is preventing us to know what is happening on the other star systems?

37 Is there any solid point in a flat earther's theory?

38 It might just be my imagination, but 30 years ago when we discovered extra-terrestrial planets, it seemed like astronomers and scientists were totally surprised. If so, why would they be surprised at something sci-fi fans have always known?

39 Did people used to think Mars was populated?

40 If I point a laser pointer at the Moon, will at least a single photon reach it?

41 Is it likely there are multiple alien civilizations all over the universe?

42 What are some of the best rare natural phenomena that occur on Earth?

43 Can a meteorite be so big that there’s no practical way to move it?

44 Why is it that almost all planets in every Star Trek series ends with a number, such as Celtis III, or Rigel VII?

45 In layman's terms, why does the singularity in a black hole have to have infinite density? Can't it just be a spot with absurdly high density while not being infinite?

46 Why can’t we go straight upward above the solar system?

47 What is the status of the Arecibo Radio Observatory that collapsed several years ago?

48 If the Earth is "flat", at night, why can’t you see the Sun?

49 Can a flashlight really send light all the way to Mars, and if so, how much actually gets there?

50 Are we really sure we should believe astrophysicists? Light goes 200,000 miles per second. Can you prove that with real science? I have my doubts.

51 If the Earth is not perfectly round, how come it appears spherical in all of NASA’s pictures?

52 Why would anyone want to do anything as stupid as put a nuclear reactor on the moon?

53 What if Earth had a habitable twin planet instead of a moon?

54 If we pour water on the sun with a bucket as big as the sun, will the sun be extinguished?

55 Can you envision a technology that could mine a nebula?

56 Does it bother you that we can't see the dark matter that supposedly makes up most of the universe?

57 How is it possible that if the Earth moves through space at 18.5miles per second, that all of the constellations look the same- including brightness even from ancient times? Wouldn’t the nearest stars be dimmer and in different locations by now?

58 If gravity suddenly disappeared for 10 seconds, what would actually happen to Earth and everything on it?

59 Can a microscope eyepiece be used in a telescope to increase the magnification by 1000 times?

60 Why can't the sun warm up the whole universe?
