| Posted: 27 Oct 2018 09:03 AM PDT To be more specific, are there well understood evolutionary histories of the animals native to the Hawaiian Islands or Iceland, for example? [link] [comments]  |

| How bright is the center of a galaxy? Posted: 27 Oct 2018 09:44 PM PDT When you see pictures of other galaxies, from my understanding, there's a ton of light due to the supermassive black holes and probably a ton of stars near the center. If you were on a planet in that area, would your night sky always be bright? What would it look like? Sorry for the bad formatting as I'm typing from mobile. [link] [comments]  |
| Why do flames always burn upwards? Posted: 27 Oct 2018 08:30 AM PDT When we burn something, why does it always burn upwards? What causes the fire to take a particular shape? [link] [comments]  |

| Why isn’t 1 considered a prime number? And for that matter, maybe zero too? Posted: 27 Oct 2018 07:30 PM PDT This might be dumb... but I thought a prime number was a number that is only divisible by one and itself... well both are true for one. Sure it's redundant, but still. And zero—clearly it can be divided by one. I get that dividing by zero is a big no no, but it seems like a weird case for zero divided by zero. [link] [comments]  |
| How do you calculate acoustic wavefront db dropoff? Posted: 28 Oct 2018 12:44 AM PDT I understand the inverse square law, and how to calculate point source volume, but how does this apply to a wavefront? [link] [comments]  |
| Why don't we use therapeutic hypothermia when dealing with anticoagulation, or brain bleeds, etc.? Posted: 27 Oct 2018 01:37 PM PDT If ice can help a bruise by constricting blood vessels, why don't we use that on a greater scale, like for people on blood thinners, or for brain bleeds that won't clot?

| How big does Reynolds Number get in real life pipelines, such as oil pipelines? Posted: 27 Oct 2018 12:00 PM PDT I couldn't find any actual numbers for this, wanted it as a reference point for a project I am doing. Thanks in advance. [link] [comments]  |
| Posted: 27 Oct 2018 12:55 PM PDT According to Wikipedia "Charges correspond to the time-invariant generators of a symmetry group, and specifically, to the generators that commute with the Hamiltonian" Can someone dumb that down a bit? How does charge lead to two particles exhibiting a force? Do the different type of charge lead to the same type of force being exerted on carriers of a charge (i.e. does color charge attract or repel like electric charge)? [link] [comments]  |

| Posted: 27 Oct 2018 08:05 AM PDT I wasn't sure if the salt in the sea water would cause issues or not. I also figured that using sea water might be more cost effective with where Cape Canaveral is situated. [link] [comments]  |

| Can a linear particle accelerator be powered by chemical cells? Where does the energy come from? Posted: 27 Oct 2018 06:18 AM PDT That is, can a battery be used to create an electric field between two plates, which is used to accelerate an electron for example? Would the battery discharge? If so, how? Edit: the electron would be produced by another source, and the battery is just used to accelerate it [link] [comments]  |

| Why do Muon Catalyzed Fusion happen at such low temperatures? Posted: 27 Oct 2018 05:39 AM PDT I saw a minutephysics video talking about how Muon Catalyzed Fusion can occur at room temperature because using Muons instead of electrons makes atomic radii much smaller and therefore much more likely to reach with each other. However, by that logic, shouldn't nuclear fusion happen all the time around the temperature where hydrogen gas becomes ionized because then the atomic radii become as small as the nucleus? I thought the reason that nuclear fusion requires such high energy is because you need to be able to overcome to proton-proton repulsion enough to let the strong force take over at close distances. How does using Muons allow us to accomplish this at less than room temperature? [link] [comments]  |
| How do we actually know the age of the Earth? (Repost) Posted: 27 Oct 2018 02:55 PM PDT I come from a math background and I'd like to know the methodology of how we get the estimates we all agree upon today regarding the age of the Earth. I have looked at many websites and articles but they always beat around the bush and never answer the question. I just want to know how to calculate the age of the Earth, which I think would be a good activity in a math class. I've heard about radiometric dating but I haven't found a clear presentation on it. So, how do we get that the earth is 4.543 billion years? Note: I posted this under Chemistry, here. I wasn't sure what flair to choose. [link] [comments]  |

| Is it possible to create a triplet of quantum entanglement? Posted: 26 Oct 2018 10:01 PM PDT So in other words you entangle 1 qubit to another, the 2nd to a 3rd and the 1st to the 3rd. Because if you are, if you read the first qubit as a 1 what would the other 2 display? [link] [comments]  |
| Why do humans not enter the rage phase of rabies and begin attacking others? Posted: 26 Oct 2018 08:25 PM PDT I was reading this and then did my own research on this twisted, evil microorganism and it occured to me that not one human has entered the rage phase. At most I saw a vid of a clearly infected child under its partial control with a entirely red body, a foamy mouth and screaming out once. [link] [comments]  |
| What is at the edge of the universe? Posted: 27 Oct 2018 08:28 AM PDT When scientists say the universe is all "space and time" do they mean all space and time within which matter and energy can exist? (I always thought space was infinite) If not I have some questions: If the universe is finite (including space), then if I am at the edge of the universe, what would I see? If I was at the edge of the universe and kept going, where would I end up, given that there is no space? Is there a wall or something? [link] [comments]  |
