| Why do the electric field lines at the end of two parallel plates curve? Posted: 05 May 2017 02:44 AM PDT I believe it is called the end-effect? However I would like to know why this happens. Here is a picture of what I mean: Diagram [link] [comments]  |

| What is the earliest a habitable planet could have formed? Posted: 04 May 2017 05:56 PM PDT The estimated age of the universe is 13.82 billion years, and the estimated age of the earth is 4.54 billion years. The first multicellular life according to wikipedia is 4.25 billion years ago. This could mean that the earth became 'habitable' after 290 million years, when the universe was 9.57 billion years old. If the universe was fairly homogeneous after its creation, I would assume that for a while it remained above the temperature life could have started. In addition, being before the time when planets could have formed and organized into stable orbits and conditions. Then when was the time after the creation of the universe that a planet would have been able to form and sustain life? [link] [comments]  |
| To what extent can ℝ^n be generalized for n∉ℕ? Posted: 04 May 2017 05:24 PM PDT I know that ℝ0 is a point, ℝ1 is the number line, ℝ2 is the Cartesian plane, etc. I also know that we can generalize n-dimensional space to all positive real n to include fractals (for instance, the dimension of the Sierpinski triangle is log(3)/log(2)≈1.585). Is there any meaningful way to extend n-dimensional space to negative n? Complex n? Matrix N? I haven't heard of this being done, but I also know that once mathematicians define something, they like to generalize it far past what makes sense in terms of the original definition—back when numbers were just for counting, the concept of negative numbers seemed completely nonsensical.

| What happens to mass in particle smashing? Posted: 05 May 2017 12:53 AM PDT I've been wondering this for a while. What happens when particles are smashed together in, say, the Large Hadron Collider? Doesn't this violate the Law of Conservation of Mass where mass cannot be destroyed? Or is there another process going on where they meld together? [link] [comments]  |
| Do humans emit X-rays from blackbody radiation? Posted: 04 May 2017 02:39 PM PDT Infrared is the most well-known light emitted by humans, but what about the other frequencies of light? It seems by Wien's Law that there should be some–albeit a tiny amount–of every frequency emitted, but is this actually the case? [link] [comments]  |
| Posted: 04 May 2017 04:31 PM PDT I don't know if that makes sense, but if a star were to eventually burn out and turn into a white dwarf or neutron star or something of that sort, its gravity would be around the same right? Wouldn't objects in their vicinity be affected by the gravity and therefore have kinetic energy constantly? [link] [comments]  |
| Why don't we feed our livestock with livestock? Posted: 05 May 2017 06:50 AM PDT It would save a lot of resources if we fed our livestock with the same kind of animal, and given that they are the same animal, this means of feed would account for practically all of the livestock's nutrition needs, wouldn't it? Why aren't we doing this? I know that cattle, for instance, are herbivorous and obviously wouldn't eat another dead cow lightly, but couldn't they be fed livestock in a different form, like pellets, for instance?

| Is there any kind of measurable difference in an object when its potential energy is increased? Posted: 04 May 2017 07:18 PM PDT For example, a ball at the bottom of ramp vs. at the top. It now has potential energy that it did not have before. Does this slightly increase the object's mass or is the only measure of potential energy the difference in height? If it is the latter, does this mean people at the exact same altitude anywhere on the planet have the same potential energy as each other? [link] [comments]  |

| Conceptually, how does the speed of light relate to the permeability/permittivity of free space? Posted: 04 May 2017 06:27 PM PDT I know the equation that relates the three constants: c=(ε0*µ0)-(1/2) However, I never understood why this worked or if there was a conceptual reasoning behind it, so any explanation would be greatly appreciated.

| Is it possible to know how much of the total universe is occupied by the observable universe? Posted: 04 May 2017 02:23 PM PDT I feel like this is a pretty dumb question because it seems unanswerable by definition, but I've been surprised many times by science in the past. Is even a horrifically uncertain yet still better than random estimate possible? [link] [comments]  |

| What is actually happening when materials experience friction? Posted: 04 May 2017 05:51 PM PDT We say that when two materials rub against each other, they experience friction. Are they actually touching? How does them rubbing together cause heat? [link] [comments]  |
| Is it possible for a star to form exclusively from a cloud of Helium? Posted: 04 May 2017 01:26 PM PDT I know that most stars form from a cloud of gas from the remnants from a super nova, which most of it is hydrogen, but could a star come together with helium? If that is the case then it would start with an He core and star fusing that straight into C? [link] [comments]  |
| How do fish (and other ocean-loving creatures) see underwater? Posted: 04 May 2017 04:07 PM PDT What are the "mechanics" of how their eyes work being underwater their whole lives? And how far can they see? Is it likes us wearing goggles? How's does depth perception work for them in those conditions? [link] [comments]  |
