14 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?

15 Would spaghettification hurt?

16 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?

17 Why do scientists say that the universe is flat?

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

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

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

21 Do British people know what the Sun looks like?

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

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

24 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?

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

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

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

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

29 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?

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

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

32 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?

33 Did people used to think Mars was populated?

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

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

36 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?

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

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

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

40 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.

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

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

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

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

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

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

47 What would happen if an asteroid the size of Europe was discovered to undoubtedly be on a collision course with Earth with impact expected in a year?

48 The moon was set to rise at 11:11 a.m. Isn't the Moon supposed to come out at night only?

49 Is it possible that there are exoplanets within our solar system that we have yet to discover?

50 Would an arrow puncture a target if playing on the Moon or Mars?

51 What would happen if a sphere of pure gold with a radius of 10 AU suddenly appeared 3 light years from Earth?

52 If the Earth is rotating, why isn't its rotation noticeable to us like the rotation of a fan is noticeable?

53 I believe the Earth is flat because there has never been a photo of the round Earth. How do scientists feel about this?

54 What's your toughest question to flat earth inventors?

55 How can you tell if a stone is a meteorite?

56 How big would a black hole have to be to weigh the same as the Sun?

57 Did any famous scientists believe in a flat earth? If so, what was their reasoning and did they have any explanations for how it could work?

58 How do we know there are other galaxies when we can't see a fraction of our own Galaxy?

59 Is there any common sense that makes a flat earth impossible even without scientific knowledge?

60 Are the spaces between the galaxies absolutely nothing?
