| Is the mass of virtual particles accounted for in the mass of the galaxies? Posted: 18 Mar 2016 12:56 AM PDT As I understand it, virtual particles pop in and out of existence by some probabilistic model. On a small scale, I'd imagine this amounts to nothing,, but on a galactic level, shouldn't there be some quantifiable minimum total mass that they would contribute at all times? And if so, has this been considered as a candidate for dark matter? [link] [comments]  |
| Regarding the higgs boson, and its potential implications? Posted: 17 Mar 2016 09:13 PM PDT So I do fully admit that I'm basically an armchair physicist and not (fully) educated formally in the matter of quantum mechanics. In this admission, I fully welcome any comments completely debunking this idea. edit: Oh, and if this is posted in the wrong sub, let me know so I can take it down and post elsewhere.

| Can people with lazy eye choose which eye to use and alternate between them? Posted: 17 Mar 2016 03:12 PM PDT Hey there! I'd like to preface this by saying that I am not asking for medical advice of any kind, just checking if anyone has any insight on the subject, as google turns up nothing. Also, I apologize for the crude (and/or rude) terminology, but there are multiple issues with the same effect. I know that lazy eye usually happens when the muscles controlling the movement of the eye are somehow affected, or the brain is not processing the visual signal properly, which results in the eye veering off to one side and the loss of stereoscopic vision. My questions - do people with such issues have the ability to choose which eye to use at any given moment? Like having the ability to use only your left eye or your right eye? Thank you for your time! [link] [comments]  |
| Posted: 18 Mar 2016 03:11 AM PDT I am a radio host and sometimes conduct radio quizzes. As a tiebreaker between two contestants, I use a "guess how many"-question, like "How much money did the local government spend on traffic in 2015?" The first contestant gives an answer. The second one then answers. What is most fair? A: That the first one guess a number, and the second guess a number? B: The first one guess a number, and the second says higher og lower? My thinking is: In scenario B, number 2 has a 50/50 chance, but I am not sure if number 1 has the same 50/50 chance, because the success of his opponent is down to 50/50? Another question: Is the fairness affected by the nature of the question, i.e. the difference between a random number and an actual number that might be, but unlikely is known by one of the contestants?

| Does competition drive down diversity in an ecosystem? If so, why? Posted: 17 Mar 2016 12:17 PM PDT I read an article recently about two types of fish in a lake. One lived in the shallow portion of the lake, one in the deep. After crawfish were introduced to the ecosystem, the two fish interbred and competed, to their detriment. The abstract for the article stated, in a way that implied that it was a known fact, that competition drives down diversity in an ecosystem. This seems counterintuitive to me. Is this the case? If so, why? e: typo [link] [comments]  |

| When you stick your hand outside of a moving vehicle, are you slowing it down? If so, by how much? Posted: 17 Mar 2016 01:51 PM PDT "How much" is very vague and dependent on basically every variable... [link] [comments]  |
| Posted: 17 Mar 2016 09:55 PM PDT I understand that a single G represents one earth gravitys effect on our body, correct? 5 G would be like x5 earth gravity, right? So how can we go multiples of negative G? Is 0 G weightless, like in space? [link] [comments]  |

| Posted: 17 Mar 2016 03:49 PM PDT I am referring to the idea that "thoughts affect reality" as claimed in this video. After some research I know this comes from a common misconception of the quantum wave function. I am just a little confused on what this misconception is. [link] [comments]  |
| Posted: 17 Mar 2016 11:58 AM PDT While I was writing all the square numbers down I tried to find a pattern, so I wanted to see the difference between each square, I noticed that there were all odd numbers in order apart, i.e 1,4,9 and 16 are respectively 3,5 and 7 apart. Thank you for answering! [link] [comments]  |
| Why is the Prandtl number for the Earth's mantle so high? Posted: 17 Mar 2016 10:30 AM PDT On Wikipedia's entry for the Prandtl number, it states that the earth's mantle's Pr is around 1025. Does plate tectonic activity contribute to a high kinetic viscosity (∴ high viscous diffusivity) relative to a very low thermal diffusivity, or is the latter just extremely low relative to a low viscous diffusivity?

| If you traveled underwater faster than the speed of sound (in water), would you get a sonic boom? Posted: 17 Mar 2016 04:41 AM PDT And if so, how would it manifest? Would there be a bubble of air or something like that? I assume it would be quite a bit different from how sonic booms work in air. [link] [comments]  |
| How does the Y chromosome attain genetic diversity? Posted: 17 Mar 2016 09:14 AM PDT If it's the same Y chromosome passed down the male side, how does a person achieve genetic diversity like they do with X chromosomes? [link] [comments]  |
