| What are the colorful lines in NASA's Pale Blue Dot image? Posted: 03 Jan 2020 01:06 AM PST |
| What was radioactivity called pre-Curie? Posted: 03 Jan 2020 05:34 AM PST Before Marie Curie coined the term "radioactivity," what was the term for that phenomenon? [link] [comments]  |
| Is there a theoretical limit to how much detail we can get from satelital images? Posted: 02 Jan 2020 03:43 PM PST The resolution you can get out of Google maps is pretty good, and we can make our individual persons most of the time. Will the technology ever get so good that we will be able to make out, say, an ant? If not, does the limit come from our technological capacity or is the limit a theoretical one, where it's physically impossible to get more resolution/detail? [link] [comments]  |
| How can a pregnant mother generate a sterile environment? Posted: 02 Jan 2020 11:47 PM PST I watched a Kurzgesagt video which said that human fetuses are in a sterile environment until they are born. From what I understand about microbiology, creating a sterile environment is hard. Pressurized oven level hard. If I can wash my hands until I flay the skin from my fingers and still not get all the bacteria off, how can a mother generate such a large space of sterile room for an unborn? [link] [comments]  |
| Posted: 03 Jan 2020 02:12 AM PST Like in a car or plane crash. I'm just thinking like, when they say to brace for impact, if it is a good idea to keep your neck pillow on? [link] [comments]  |
| What is the heat of vaporization for NaCl? Posted: 02 Jan 2020 04:10 PM PST I found that its boiling point is 1738K, but I can't find anything for its heat of vaporization. Wikipedia lists the heat of fusion, but not the heat of vaporization. Am I missing something? [link] [comments]  |

| How human milk is made? I mean all the way through: from food to bloodstream to mammary glands Posted: 02 Jan 2020 02:42 PM PST Is there a description of the whole process? I mean all chemical reactions, and how mammary glands extract nutrients from blood and convert them to milk and full understanding of how they work. Also, are there machines which can turn food into bioidentical milk, let's say corn into human milk or grass into cows milk? [link] [comments]  |

| Can you measure the size of a galaxy using Cepheid variable stars? Posted: 02 Jan 2020 03:36 PM PST Specifically, could I measure the size of the Milky Way using the pulsation period of variable stars? [link] [comments]  |

| How steep must an incline be before you start to fall instead of slide down it? Posted: 02 Jan 2020 03:47 PM PST I've been curious about this for days and I can't seem to find an answer on Google. The logical answer would be a 90 degree angle but wouldn't an 89 degree angle still cause one to fall still? What about an 88 degree angle and on? [link] [comments]  |
| How much water is on the moon? Posted: 02 Jan 2020 07:36 AM PST From some quick googling, I've found that evidence of ice was found on the moon, but I don't anything saying how much could exist. With NASA's new lunar base campaign, it sounds like they're counting on significant amounts of water to be present in order to sustain a permanent base, and possibly having the moon as a fueling station using the water. What has been found so far? [link] [comments]  |
