| Humans use titanium dioxide for so many things, what will happen when we run out of it? Posted: 01 Nov 2019 08:40 PM PDT From my research it doesn't seem like it's a renewable resource, at least not at the rate we use it? Aren't we going to run out of it at some point? [link] [comments]  |

| When an object absorbs a liquid, is energy lost? Posted: 01 Nov 2019 08:36 PM PDT Take a towel for instance. When it absorbs water it moves mass but doesn't appear to generate heat. It also seems to be completely reversible, i.e. you can squeeze the towel enough and have a puddle of water and a dry towel. [link] [comments]  |
| Is it ok to harvest wind energy? Posted: 01 Nov 2019 04:24 PM PDT If Saharan dust feeds the Amazon plants, I imagine convection currents play a huge role in ecosystems. Is it ok to harvest this energy? [link] [comments]  |
| Does everything in the universe pull on everything else in the universe? Posted: 01 Nov 2019 07:46 PM PDT My high school physics teacher told my class that we all pull on everything in the universe. Today I was curious how long it takes for gravity to travel to objects and I looked it up on google and was told that it moves at the speed of light. But I also have been told that space is expanding faster than the speed of light. So I'm wondering if it is true that everything pulls on everything else in the universe? [link] [comments]  |
| Posted: 01 Nov 2019 07:55 PM PDT So I was watching PBS Space Time and neutrinos was a topic and the presenter Matt O'Dowd said that physicists have only discovered left handed neutrinos and right handed antineutrinos. Since neutrinos have an incredibly tiny mass compared to other particles, does this mean that sterile neutrinos, which are the opposite of normal neutrinos, are the same thing as heavy neutrinos as they're opposite so the opposite of a tiny mass particle is a heavy mass particle. Also, I also learnt that the value of the Hubble constant has conflicting data taken from 3 different sources, each being the Cosmic Microwave Background Radiation, the afterglow of the Big Bang, Type 1a Supernovae, when a white dwarf takes matter from a larger star that it in a binary pair with it until it explodes, and Quasars, black holes with extremely bright accretion disks. He said that this shows that, if all the results are taken properly, this shows that the Cosmological Constant is increasing over time. He also said in another video that the cause of this could be unknown physics such as a fast moving particle such as sterile neutrinos. In a third video, he says that if more neutrinos exist, such as the sterile neutrinos, then it's evidence that the early universe would've expanded faster than current observational data assumes. So does this mean that sterile neutrinos are the answer to this discrepancy and if not then what is? [link] [comments]  |
| Posted: 01 Nov 2019 03:51 PM PDT Basically women tend to develop schizophrenia later than men, in their mid to late 20s. This is also around the time that a lot of women start their family's. How do therapists determine if it is PPP (postpartum psychosis) or schizophrenia (or something else)? Plenty of women with PPD (postpartum depression) don't get diagnosis or treatment until quite a while after they have given birth so I don't think the time frame of the illness is necessarily a reliable indicator of which the woman is suffering from. Do you think there is a lot of misdiagnosis? How does treatment vary between the two illnesses? If the PPP is resistant to therapy does the diagnosis get changed to schizophrenia? Also if a woman has a history of schizophrenia in her family is she more prone to PPP? Have any official studies been conducted into this, and if not what is your opinion? [link] [comments]  |
| Posted: 01 Nov 2019 10:35 AM PDT An object that is in motion stays in motion right, so if you were to spin a huge object really fast, and then use a machine to harvest that rotational momentum when energy is needed, could you not spin up an object in space and leave it spinning for as long as you want until you're ready to use its energy? Could spinning objects serve as simple batteries? Is it viable to harvest energy from a spinning object? I posted this yesterday BTW and got 0 replies. AskScience is dying I think, or maybe just over-moderated. I'd be open to suggestions to alternative boards. [link] [comments]  |
| The universe is expanding, but is it measurable within the scope of a single galaxy? Posted: 01 Nov 2019 06:34 PM PDT So from my understanding, the universe is expanding, and the rate of expansion is increasing. Are we able to observe this expansion on the scale of a single galaxy? Like, is the space in between the stars in the milky way observably expanding? Or is it only visible at a much larger scale? Thanks. [link] [comments]  |

| Posted: 01 Nov 2019 07:49 AM PDT I watch this video https://www.youtube.com/watch?v=1Nh_vxpycEA&t=285s by Tom Scott on how 'stale air' which was marked by an increase in CO2 levels caused certain health problems in individuals. Is this directly because of the Carbon Dioxide molecules themselves, or is it because an increase in CO2 levels implies a decrease in O2 levels? [link] [comments]  |
| Posted: 01 Nov 2019 08:31 AM PDT I'm assuming their food is getting better too along with medicine. For example a Great Danes life expectancy is 8-10 years. Has that risen over time / will rise in the future? [link] [comments]  |
| What, scientifically, makes hills suboptimal locations for farming? Posted: 01 Nov 2019 02:41 PM PDT When I read about history, it seems clear that hills are not very good for farming compared to flat land. Especially in Europe, hills and mountains seem to be reserved for tribes or poor populations who were not wealthy or powerful enough to occupy better farmable land for themselves. I tried searching on Google about what exactly makes uneven land so bad for farming, but all I found were articles about modern hill farming and terrace farms, none of which really answers what I want to know. So in short, what physical characteristics of hills makes them bad for farming crops? Does this apply to all crops, or just the most profitable types? Does it have to do with uneven sunlight, bad soil, rocks, water flow...? [link] [comments]  |
| Posted: 01 Nov 2019 09:53 AM PDT When a scientist looks through a telescope, no matter what type it is, they aren't seeing a current snapshot of anything. The light from the objects that are observed are arriving at different times depending on how far away the object is. Since these objects are all out of sync, how do astronomers and cosmologists make predictions about how the objects are interacting with each other when its impossible to view them together in the same time? How do they account for this when making predictions about things like gravitational influence, etc.? [link] [comments]  |
| Why VX nerve gas poisoning Is treated with atropine? Posted: 01 Nov 2019 03:17 PM PDT I red that nerve gas poisoning is treated with pralidoxime, diazepam and atropine subministration. Wasn't atropine the main active alkloid in Datura stramonium? The one that causes hallucinations, spasms and paralysis? Why would you give something that paralize to a paralized patient? How does It works? [link] [comments]  |
