How do spiders choose a location for their web? Posted: 21 Jun 2017 07:09 PM PDT So this is a multi-part question, I suppose. First time posting here and asking you guys about something. Whenever it is that spiders are grown and ready to set up shop, spin a web and wait for dinner (the species that do hunt this way), how does it choose the location? How does it know where the ideal place is to collect food? How far do they travel to seek out such a place, if they do "seek" out certain places. Do they just drop a web whenever and wherever they are hungry? Move on when they get bored to a new place? Going through some things in the bottom of the closet, stuff that gets moved on occasion, a couple times a month maybe. Inside a shoebox (and similar places) there are usually some tiny, tiny spiders with their homes set up. Is there really a steady food supply in there, tucked away, door shut? Obviously I know there is tiny food for them galore, but really, in my closet? submitted by /u/supersayanssj3 [link] [comments]

[Physics] How does gravity work on a torus world? Posted: 22 Jun 2017 04:27 AM PDT Hey so I've been thinking about this for a while and would like a definitive answer. If I lived on a torus planet where the cross-section of the torus was the diameter of the earth and the hole in the middle of the torus was around the distance from the earth to the moon. Assuming the torus is not rotating so no artificial gravity. Where would gravity pull me towards? My slightly educated guess would be the center of mass of the torus. If this is the case then my follow up question would be, if gravity is weaker over distance, could I increase the size of this torus to the point where I would no longer be pulled to the centre? submitted by /u/HymirTheDarkOne [link] [comments]

Why do UV stamps and UV paint show up under blacklight, but not under sunlight? Posted: 22 Jun 2017 07:06 AM PDT If the sun emits UV light, why can a blacklight with a UV bulb illuminate things that the sun can't? Is it just a question of strength or concentration of light waves? submitted by /u/danceswithlesbians [link] [comments]

Why is the imaginary number defined as i^2 = -1, rather than i = sqrt(-1)? Posted: 22 Jun 2017 04:47 AM PDT In case of i2 = -1, there are two possible outcomes for i. So why wouldn't you just define i? submitted by /u/JustReadingAndVoting [link] [comments]

Does having AIDS reduce allergy symptoms? Posted: 21 Jun 2017 12:08 PM PDT I know that allergies are caused by your immune system targeting harmless molecules.

How does a down quark turn into an up quark in neutron decay? Posted: 21 Jun 2017 11:53 PM PDT I had thought that an electron was a quark-antiquark pair, but apparently this isn't so. So neutron decay starts with a neutron (udd), and in the end, there's a proton (uud) and two leptons. Are up and down quarks, then, not fundamentally different things? Are 'upness' and 'downness' just different quantum states of something quarky? submitted by /u/SurprisedPotato [link] [comments]

Why does the multiverse theory have an infinite number of universes? Posted: 21 Jun 2017 12:27 PM PDT Every time I see the multiverse theory mentioned on TV, movies, books, comics, etc. they have the same basic concept of infinite universes, some very like ours, some very different. While the idea that there are different universes with different laws of physics sits fine with me, the concept of there being one universe exactly like mine but I'm made of corn, in another the only difference is I have a different colour shirt on, etc. seems ridiculous. Why does the theory have 'infinite' rather than many universes? submitted by /u/PermanentSubstitute [link] [comments]

If I woke up 3000 years ago, would it be realistically possible to create electricity in a usable form? Posted: 21 Jun 2017 12:18 PM PDT I frequently have dreams where I wake up in the past and am completely useless, and so I'm wondering if it would actually be possible to create modern technology without any support structure in place. I know the basics for creating electricity: A magnet, some conductive wire, and something for the electricity to work on, but would it be possible to create a powerful enough magnet from scratch? How would I go about making copper wire before copper wire is a thing? Could I create my own light bulb? submitted by /u/RadBadTad [link] [comments]

Why does cold water feel, or seem to feel, so much colder than cold air? Why does 50°F water seem so much colder than 50°F air? Posted: 21 Jun 2017 12:29 PM PDT I can walk outside in a pair of shorts and a t-shirt when its 50°F outside just fine, but when I get in 50°F water, I feel like I'm going to die.

How can the same protein isoform (PrPSc) cause so many different diseases? Posted: 21 Jun 2017 06:35 AM PDT Everywhere I read about prionic diseases, it always talk about the PrPSc protein, making a distinction between it and its isoform PrPC. But I imagine that not all PrPSc are the same, since they exhibit some differences in terms of symptoms, incubation period... But I can't seem to find what exactly is the difference between the prions that cause each disease. submitted by /u/TridentBoy [link] [comments]

How do they build highways in loose sand? Posted: 21 Jun 2017 04:20 AM PDT My question is basically only what is in the title, I am trying to find out how paved roads in the desert are made. Normally, constructors lay down a subbase on the subgrade (which in this case is sand) then a base course over that and then the pavement. The subgrade is supposed to hold the whole weight of the road, how do they solve this in the desert? submitted by /u/Jacareadam [link] [comments]

This might be an idiotic question, but do things really fall at the same rate? Posted: 21 Jun 2017 01:02 AM PDT If F=G(M1*M2/d2) then objects don't actually fall at the same rate, right? It's just that any experimental observation we've done on Earth shows that they do because M2 being the mass of Earth is so large that comparing different M1s is kind of irrelevant? submitted by /u/dcrico20 [link] [comments]

How hot is a nuclear meltdown? Are there materials like tungsten which could stay solid indefinitely?

What causes phone's GPS to drift? Posted: 21 Jun 2017 04:52 AM PDT I currently have an iPhone 6, but this question is probably general for all modern phones. What causes GPS drift (phone thinks it is somewhere and then somewhere else meters away, then somewhere else) and how can it be created by placing the phone in a specific location (like a box made out of something that doesn't disable the signal, only weakens it). More info: Mainly asking for Pokemon Go, but interested in GPS technology too. submitted by /u/webs2slow4me [link] [comments]

How do different aged organs effect receipients of organ transplants? Posted: 20 Jun 2017 09:51 AM PDT For instance, if a 20 year old patient received a kidney from a 60 year old donor, by the time the patient was 60, that would be a 100 year old kidney! Is there reason to think that the kidney would "stop" working at a certain age, regardless of the patient's age? Or, in reverse, if for example, a 75 year old received a kidney from a 20 year old, would their body be shocked at how relatively healthy this one particular organ was? Even if the rest of their body was relatively healthy, the body would have slowed down compared to a 20 year old! Do hospitals try to match organs by age in addition to blood type, etc? submitted by /u/bandroid887 [link] [comments]

How does light get pulled back into a black hole? Posted: 21 Jun 2017 07:07 AM PDT Say I was standing inside account black holes event horizon holding a laser pointer. If I turned it on and pointed out outwards perpendicular to the event horizon, how does the light get pulled back into the black hole? The photons coming out of the laser would need to accelerate towards the black hole which means that their velocity would decrease to less than c. My understanding is that light always travels at c in a vacuum, so how is it possible for the photons' velocities to decrease? I think I might be confusing how photons behave with how ordinary matter behaves, but I'm not an expert.. submitted by /u/StupidQuestionsAcnt [link] [comments]

Would it ever be possible for humans to have gold-colored eyes (like cats, owls, wolves, bald eagles, etc.)? Posted: 20 Jun 2017 05:06 PM PDT I am wondering if it would ever be possible, through a genetic-engineering perspective, for humans to have the gold-colored eyes that other animals have. Let's say you have a futuristic culture in which designer babies are the norm, and diseases have been all-but-eradicated in this better "breed" of human which has resulted through generations of careful genetic selection. If these futuristic peoples have the ability to pick and choose certain phenotypes for their children, isn't there some way for a gold eye color to come about (as it would be an alluring and desirable trait)? Can we not simply "inject" the pigments from other animals exhibiting golden eyes into human eyes, or splice the genes from these animals into human DNA to allow for this to be a new genotype able to be passed on from parent-to-parent? Please help... I've done tons of research but can't seem to find the answer anywhere. I need to know if this is possible for a novel I am writing. submitted by /u/ShowMeTheNugget [link] [comments]

What would it look like inside a star? Posted: 21 Jun 2017 02:46 AM PDT So, incredible heat and pressure and magnetic forces from the fusion, but how much fusion actually goes on at a time? Stars last billions of years, so all their material clearly doesn't undergo fusion at once. We know what a fusion explosion looks like on earth, but what does it look like in a star? How long does it expand before it runs into other fusion explosions? How many fusion explosions are there in any given, say, square kilometer of space per minute? 1? 1 million? submitted by /u/naciketass [link] [comments]

What is in the vacuum of outer space? Posted: 19 Jun 2017 05:37 PM PDT To clarify, what exists between, for example, to planets? There's no air or other gases (in most scenarios), so what fills the empty vacuum of space? It is my understanding that a perfect vacuum, an area in which literally nothing exists, is impossible, so by extension something needs to inhabit that area. So what exists in the void of space? submitted by /u/A_box_of_Drews [link] [comments]

Would I experience the same pressure 10 meters below the water regardless of container size? Posted: 19 Jun 2017 11:11 AM PDT I'm learning about SCUBA diving and the initial reading about water pressure got me thinking. If pressure is just the weight of the water above you, do I experience the same or less pressure at the bottom of a 10-meter tall glass of water as I would at the same depth in a 100 meter wide swimming pool or a many miles wide ocean or lake? submitted by /u/orangecrushucf [link] [comments]

Is it possible to cancel out AC current the same way sound gets cancelled with an inverse wave? Posted: 20 Jun 2017 04:20 AM PDT I was wondering since both AC and sound are waves. I know that the way sound cancelling headphones work is by simply playing an inverse wave of the sound it is trying to cancel. This way the two waves cancel each other out, and silence is formed. Are we able to do something similar with ac current where we would match the frequency​ to "cancel" any current? submitted by /u/15feet [link] [comments]

What happens to human cardiac muscle as you do cardio exercises? Does the heart micro-tear like skeletal muscle? Posted: 19 Jun 2017 10:33 AM PDT I've been having a hard time finding good explanations online. Does the heart "micro-tear" during aerobic or anaerobic work the same way skeletal muscle does during weight training? I've always learned that the heart does not grow because an enlarged heart is a terrible thing. So how exactly does a heart "get stronger" from cardio work? Is it perhaps the whole pulmonary system that changes and not just the heart? Thank you! submitted by /u/ass_hat_mcgee [link] [comments]

Is it theoretically possible to deconstruct a nucleus into its substituents and reconstruct a nucleus from the subatomic particles? Posted: 20 Jun 2017 03:33 AM PDT For example, take some Oxygen atoms, deconstruct it into its Protons/Neutrons/Electrons & fuse them into carbon atoms?

What factors can affect the magnetic field strength of planets and stars? Posted: 20 Jun 2017 02:00 AM PDT I believe I have a basic understanding of how planetary magnetic fields can be formed. I know that the core of such objects should be molten and conductive and that they should spin fast enough for this molten mixture to interact with each other to produce a field. However, I am uncertain as to what exact factors can affect magnetic field strength and how they really work. For example, I recall Jupiter's magnetic field is incredibly strong relative to the Earth but is its strength really all to do with the gas giant's size and rotation rate? What sort of relationships do various factors have on a field's strength in celestial objects? submitted by /u/SyzygySoldier [link] [comments]

To test for Quantum Entanglement, two particles are generated such that their total spin is zero, and that one's spin will be opposite to the other. Why is it "surprising" that this property is maintained over arbitrary distances, if the particles were generated for that very purpose? Posted: 20 Jun 2017 05:34 AM PDT I also understand that the measurement of their spin can be seen as an "action" performed on the particle, but I still don't understand how it is surprising that two particles designed to be opposite to each other continue being opposite to each other over arbitrary distances. submitted by /u/BarelyLegalAlien [link] [comments]
