| Does dark energy actually exert a force? Is it actually energy? Posted: 24 Mar 2019 03:38 AM PDT Been reading about this recently and I'm a little confused as to how it's supposed to work. If every point is expanding from every other point, how can any quantifiable value of force be determined for it? If it's actually antigravity -something like negative mass particles appearing with vacuum energy and annihilating or whatever- doesn't that break causality because negative mass allows stuff like building FTL drives? Articles also say it's a force being exerted on the fabric of the universe itself, but is that quantifiable too? [link] [comments]  |

| What is the smallest organism capable of learning? Posted: 23 Mar 2019 06:45 AM PDT From my understanding most microbes interact with their environment but are not capable of pattern recognition or learning based on experience. They simply react as they were programmed to by their DNA. Mice can be taught to run mazes. I want to know what is the smallest creature that has been shown to have intelligence or learning capabilities. [link] [comments]  |

| Posted: 24 Mar 2019 06:21 AM PDT Would it behave the same as an ion? or would they just repel each other no matter how much force you use to keep them together? Say you include a neutron would that allow the now 3 particles to form 1 exotic particle? [link] [comments]  |

| Does the lethal dose scale linearly even for very fat people? Posted: 24 Mar 2019 04:37 AM PDT Lethal dose is usually given as per body weight. My question is, if I eat a lot now, get really fat and double my weight, is 'my' lethal dose now twice as high? [link] [comments]  |

| Posted: 24 Mar 2019 01:07 AM PDT As the title says, I'm sure I heard/read/saw somewhere that some animals won't go into heat or ovulate or mature sexually if the external environments are unsuitable, such as no suitable breeding males, insufficient food or other issues. If so, is there a term for this suppressed ovulation or delayed sexual maturity? [link] [comments]  |
| Has anyone ever witnessed a star death ? Posted: 23 Mar 2019 12:07 PM PDT I understand the time difference of how long it takes light to come to Earth from stars, galaxies, and other wonders of the night sky. Has there ever been a recorded time when someone just so happened to be looking in the right place at the right time and has seen that light stop ? In essence, watching a star die.

| Posted: 23 Mar 2019 07:08 AM PDT This is one that's been on my mind a lot lately. So I play piano and whenever I play, my dog wouldn't leave the room or anything, would just sit there and sometimes even comes in while I'm playing. I find it strange as if there is any erratic, unusual noise like a loud piano note she is fine but if I watch rugby and shout or any other loud noise she would leave the room. It would be the same if I'm listening to loud music. I'm just wondering if that's just something to do with her being able to tell the mood of the situation or if she has an appreciation for music or is neutral with it, super confused please help.

| Posted: 23 Mar 2019 07:42 AM PDT It seems like there is a high upper limit to how much data can be transmitted simply by adding channels and increasing bandwidth, but wouldn't the harder, lower limit be on how quickly pulses can be generated/received whilst remaining intelligible?

| Is it possible to generate a neutrino beam using an electron beam? Posted: 23 Mar 2019 12:03 PM PDT I know that using a proton beam is the standard, but would it be theoretically possible to somehow do it via electrons instead, using other interactions? [link] [comments]  |
| How much energy does an average post on social media take? Posted: 23 Mar 2019 09:42 PM PDT This is more about the amount of energy the servers that belong to these companies (Facebook, Twitter, YouTube, Reddit, Instagram) take to store and retrieve a post. If there are estimates which include energy expenditure on clients' devices too, that would be nice. I realize that each of these platforms have different types of posts which would probably account for most of the difference in energy expenditure (an average YouTube video probably takes more energy than an average tweet). Nevertheless, I thought it'd be interesting to know how our content on social media is adding up to our carbon footprint. And should we be worried that some of this footprint is not insignificant, that we might probably be better off not posting? I also realize the irony of making this post, but i guess curiosity got the better of me. [link] [comments]  |
