- What fills the void in the earth when we pump oil out, and are there visible structural effects on the surface? Also, has the net mass displacement to the earth's surface caused the earth's rotation rate to change?
- What happens if you freeze a super strong container full of water?
- Wikipedia says element 120 might be the last element possible to synthesize with current technology. Is this true? And if so, why can’t we synthesize further elements with our current technology? What new technology would we need to synthesize heavier elements like 121, 122?
- I'm reading into small/medium nuclear reactors for more localized power production, but they are not common-place right now. Why is that? Regular nuclear reactors have been around for a while, does scaling the reactor down result in new technical difficulties?

| What happens if you freeze a super strong container full of water? Posted: 06 Feb 2019 04:07 PM PST From my understanding, water expands when it freezes, and the expansion is what causes its container to break. However, if we have a super rigid container that's strong enough to withstand the expansion force of freezing, will the water still be able to freeze? [link] [comments]  |

| Posted: 07 Feb 2019 01:28 AM PST This was one I found from a specific company: https://www.u-battery.com/what-is-u-battery It mentions a few times how it coats the uranium molecules in carbon to make them safer. Other sources: http://www.world-nuclear.org/information-library/nuclear-fuel-cycle/nuclear-power-reactors/small-nuclear-power-reactors.aspx Talk about how the reactors are smaller and simpler but not necessarily cheaper to run, and that there are other issues in the way, mainly based on societal/legislative barriers. That same website also talks about smaller (portable) reactors that have already been used. So what are some reasons that they are not more common place now? [link] [comments]  |

| Identifying Patient Zero. How? Why is it important? Posted: 06 Feb 2019 03:46 PM PST With the measles running a muck, and news stations broadcasting we found patient zero I would like to know why that's important. [link] [comments]  |
| Why is it so hard to build a thermonuclear weapon? Posted: 07 Feb 2019 01:31 AM PST I find nuclear weapons fascinating. I've been doing some reading on the subject, and I find the mix of science and... destruction interesting. I am in no way a physicist however. The following question has reared itself: Why is it so difficult to build a thermonuclear bomb? I realize the details of the designs that are public are very vague and generalized, but still. You would think once the concepts are known, smart people would work out the kinks. Still, all countries (NK for instance) always start with simple fission weapons, maybe even never reach the thermonuclear stage. Is the difficulty in refining and designing the actual physics of a weapon, or in the manufacture and tooling of, I assume, many exotic materials? (Of course I also realize that building such things is generally not something that is encouraged by those that know how it's done.) [link] [comments]  |

| Posted: 06 Feb 2019 08:23 PM PST Basically, how to paleontologists know a fossilized bone is broken due to an activity during the animal's life and not because part of the bone fossilized poorly? [link] [comments]  |
| Can the venom of a snake or a spider harm a plant? Posted: 06 Feb 2019 07:41 AM PST I know that most venoms are not designed to attack plants, but which ones can? Is there a specific plant/specific venomous animal or bug that can harm a plant? [link] [comments]  |

| When did animals evolve wings? Posted: 06 Feb 2019 05:59 PM PST When did animals first begin to take flight? And how did they go about the process? Like when was the first bug like, Imma jump and it'll work itself out! [link] [comments]  |

| Why do we still need vaccines against measles, but not against smallpox? Posted: 06 Feb 2019 11:51 AM PST Before anything, I want to make clear I am not an anti-vaxxer, by no means. I'm simply curious about the difference between both pathogens. Smallpox was eradicated in en 1970s after a global campaign and and people don't need to be vaccinated any longer. Measels seems to have been basically eradicated until now, due to anti-vaxxers. How is that possible? [link] [comments]  |
| Does our body have a way of storing excess protein like it does with excess fat? Posted: 06 Feb 2019 10:33 AM PST There are adipocytes, but apparently there are no 'proteinocytes'. I would think that storing protein is a big evolutionary advantage, so does our body do that? And if no, why not? [link] [comments]  |
