Is there a speed of a field? Posted: 03 Jan 2016 02:28 AM PST If an infinite negative charge appeared in the universe, would all electrons/matter instantly be repelled, or would there be delay in the charge appearing and other charges being affected? Does the same apply to gravitational and magnetic fields? submitted by Amish_Harry [link] [46 comments]

Are emotions innate or learned ? Posted: 02 Jan 2016 05:16 AM PST I thought emotions were developed at a very early age (first months/ year) by one's first life experiences and interactions. But say I'm a young baby and every time I clap my hands, it makes my mom smile. Then I might associate that action to a 'good' or 'funny' thing, but how am I so sure that the smile = a good thing ? It would be equally possible that my mom smiling and laughing was an expression of her anger towards me ! submitted by lcq92 [link] [299 comments]

Can we have lenses for sound? Posted: 02 Jan 2016 04:17 PM PST So that we could derive information about our surroundings similar to what optical lenses provide. submitted by AxelBoldt [link] [33 comments]

Can a black hole be charged enough to overpower it's gravity? Posted: 02 Jan 2016 11:25 PM PST Like for example say you have a negatively charged object of some sort, could you have a black hole with a charge strong enough that it would allow that object to escape once already inside it's horizon? EDIT: tried to make the question a little clearer submitted by oblivion5683 [link] [3 comments]

Could antimatter destroy a black hole? Posted: 02 Jan 2016 01:03 PM PST Since black holes are made of matter, could a large enough quantity of antimatter sent into a black hole destroy, or at least destabilize, a black hole? submitted by Eleves_202 [link] [19 comments]

Could a gunpowder cannon launch a cannon ball into orbit on the moon? Posted: 02 Jan 2016 10:16 PM PST Could an old-fashioned cannon, akin to what you might find on a pirate ship, fire a cannon ball from the surface of the moon into the moon's orbit. Would this be possible with an older cannon, if not, would it be possible with one from a modern battleship? What's it gonna take to get a cannon ball to orbit the moon? submitted by Creatively_Cautious [link] [11 comments]

Why is it not possible to run a virtual quantum computer inside a traditional digital environment? Posted: 02 Jan 2016 11:45 AM PST submitted by kipper_tie [link] [13 comments]

What happens to the length of a light wave when it's absorbed? Posted: 02 Jan 2016 11:07 AM PST Take a photon that's emitted from a distant star and after an amount of time, arrives at your eye and is absorbed. What happens to the portion of the wave that has not yet reached your eye? submitted by DotRook [link] [5 comments]

If you have to travel faster than light to escape a Black Hole, would an Alcubierre drive-enabled ship me able to study the singularity? Posted: 03 Jan 2016 03:55 AM PST Description of the theoretical drive here. Since the drive warps SPACE instead of actually traveling forward in time, would one be able to enter and escape a Black Hole using this method? submitted by mikegates90 [link] [2 comments]

If an event is triggered if the two doors of the ladder paradox is closed simultaneously, would it occur? How can the observers agree? Posted: 02 Jan 2016 02:13 PM PST Imagine the "Ladder Paradox" (https://en.wikipedia.org/wiki/Ladder_paradox) altered in this way: A light pulse is sent from each door when they are closed, towards a detector placed exactly in the middle of the garage. If this detector receives a signal from both sources at the same time, a bomb will go off, destroying the garage. As far as I understand this paradox is resolved by the relativity of simultaneity: The observer stationary relative to the barn sees both doors close at the same time, but due to length contraction the ladder fits inside. In the ladder frame, the doors do not close at the same time, allowing it to pass through even though it does not fit inside. I have a difficult time resolving how the two observers do not agree if the doors were closed simultaneously but at the same time have to agree on the bomb exploding or not. The questions are: 1) Do the bomb go off? 2) How can the observers agree? Thank you. submitted by clykke [link] [4 comments]

Why doesn't fusion occur on earth? Posted: 02 Jan 2016 01:57 PM PST As I've understood the physics of stars and fusion, not even our sun for example achieve temperatures needed for fusion but instead fusion occurs via quantum mechanics where there is a probability for the hydrogen nucleus to simply "be" with eachother and thereby fuse. The reason the stars still can support fusion and not implode to gravity is because though the probability for the phenomena is low the sun has so much mass it still happens all the time and if so why doesn't fusion happen randomly on earth? I feel like I have critically misunderstood something here so excuse me beforehand. English is also not my native language so feel free to ask if you do not understand what I am asking. submitted by stultus1337 [link] [6 comments]

Why don't some of the more recently discovered elements have permanent names? Why is element 117 called "Ununtrium" or just "Element 117"? Posted: 02 Jan 2016 10:24 AM PST Same thing goes for Unun­trium, Unun­pentium, and Unun­octium. I meant to call Ununtrium Element 113 and not 117. submitted by redbottlecapbeercan [link] [5 comments]

How deep underground can you still find life? Posted: 01 Jan 2016 06:44 AM PST How deep dig mammals like mice and moles? How deep go worms and insects? And at what depth stop bacteria and viruses?

How do photons emmited from stars millions of light years away, or a light-bulb in a room, get distributed? Posted: 02 Jan 2016 05:08 AM PST Consider a star 500 light years away that I can see from Earth. Is this interpretation below of how this works correct? i) When i look at a star my eyes are basically detecting photons emitted by that star. ii) I could be standing at point 1, and I would see the photons "streamed" in my direction. i could be a point 2, and I would see a separate set of photons "streamed" in my direction. iii) Is there a "resolution" or minimum distance between points I could be standing at to detect the same photons? iv) If there is no such minimum resolution, given that there are infinite number of points within visible distance of that star, the star would have to emit an infinite amount of photons in every direction simultaneousely? But this is not possible, so there has to be a minimum resolution, OR the light emitted is a continuous wave emitted in all directions. v) Assuming the "continuous wave" is correct, how does ray tracing software simulations that uses "light rays" render the world correctly? Are "light rays" here a discretized section of the waveform to aid simulation and interpretation? The same question could apply to a light bulb I suppose. Thanks. submitted by sirblabla [link] [1 comment]

What would happen if Jupiter suddenly ignited, and became a star? Posted: 01 Jan 2016 08:38 PM PST I have heard before (can't remember where) that Jupiter is on the threshold of becoming a star, and it had gained a bit more mass during its formation it would have been able to ignite and been born a star. So my question is; what would happen it our solar system of Jupiter were to suddenly ignite and become a second star in our solar system? submitted by Incendium_Fe [link] [14 comments]

What is left behind when a black hole explodes? Posted: 01 Jan 2016 02:10 PM PST So through Hawking radiation, a black hole evaporates and eventually explodes. If it explodes, shouldn't that leave behind matter? Can there be an explosion without matter? Wouldn't this also mean that after the Stelliferous Era, there could be more fusion taking place as matter is left behind from black hole explosions? Couldn't this also keep the universe going indefinitely? submitted by Imissyourgirlfriend2 [link] [4 comments]

How did humans take down such large animals? *How many humans had to be involved? *How many spears were needed to take down a Mammoth? *Were any other tools used, such a rope to tie down the animal? *Did hunters spear and let the animal bleed out? *What do we know based on current hunting techniques? submitted by Puznug [link] [4 comments]

Why is this door hard to close when the window is shut? Posted: 31 Dec 2015 11:38 AM PST Here's a quick diagram of my room: http://imgur.com/64u0HoF When I walk in my room, I push the door behind me to shut it. When the window is open, the door shuts just fine. But when the window is shut, the door always stops right before it meets the doorframe, and I have to push it the rest of the way. I suspect it has to do with an air pocket being caught in the little hallway, but I'm not 100% sure. Anyone know why? Edit: And anybody know how to fix it? submitted by kevin4789 [link] [7 comments]

Why does spin change how particles work? Posted: 31 Dec 2015 03:10 PM PST I've been told that spin is a measure of intrinsic angular momentum, but I don't understand why it leads to all these confusing properties of particles and forces. I have heard that fermions with half-spin can't occupy the same space, but bosons with integer spin can, and that bosons with spin 1 cause opposites to attract and likes to repel, but spin 2 bosons have like attraction. I've also heard that because of their half-spin, fermions can be rotated 360º and end up with the opposite spin. Assuming what I'm told is correct, what is the reason for these odd properties? Is there a simple analogy to explain all of this? submitted by chunkylubber54 [link] [2 comments]

Hypothetically, can Period 8 have a further sub group like Lanthanides and Actinides? Posted: 31 Dec 2015 06:27 PM PST I guess, for one, do we know for sure that period 8 will have lanthanides and actinides? And for two, could there hypothetically be a further sub group? Like how Lanthanides appeared in period 6 and have that funky extra-extendy part. Could the table get (probably absurdly) longer?

If I hit a baseball with a bat, can the ball go faster than the speed that I'm swinging the bat? Posted: 31 Dec 2015 10:59 AM PST I'm thinking of a ball that is stationary, like on a tee. I guess that maybe the question would work better for a golf ball now that I'm thinking about it. If it is a pitched ball, can the ball ever go faster than the combined speed of the bat and the ball? Does it matter what the ball is made of, or how strong the person swinging the bat is? submitted by IUhoosier_CCCP [link] [9 comments]

What is meant by 'gravity assist?' Posted: 31 Dec 2015 07:14 PM PST It seems to me that an orbital object would gain energy falling into a gravity well, then lose all that energy climbing out the other side. How is this a net gain? submitted by yHero [link] [3 comments]

With bitcoin-like cryptocurrencies, how does a person know whether the blockchain they have is up to date? Posted: 31 Dec 2015 09:50 AM PST I understand that the blockchain of a cryptocurrency is essentially a public ledger of all the transactions in that currency, and that it's used to prevent duplicate transactions from occurring as well as tracking all the balances. How can a single client know whether or not the blockchain that it has contains the full list of transactions? I mean, it can compare blockchains with the user it's performing the transaction with and make sure that the later of the two is used; maybe it can look around at other public blockchains and make sure they're not newer? I guess I don't understand what underpins the system's trust. submitted by Bladelink [link] [3 comments]

What caused protons and neutrons to come together in the early universe? Posted: 31 Dec 2015 06:59 AM PST In the early universe, when the temperature was hot enough, there was a sea of protons, neutrons, electrons, and radiation (photons). Eventually as the temperature dropped, it became possible for protons and neutrons to come together and form atomic nuclei, though it was still too hot for electrons to bind and form neutral atoms. My question is - what caused the protons and neutrons to bind in the first place? If I understand correctly, the nuclear force keeps the nucleus together once it's already formed, but what caused the proton and neutron to bind? Why didn't all protons and neutrons continue as individual particles as the universe continued to cool? submitted by acunc [link] [4 comments]

Not sure how to word this but do programmers have to have technical knowledge of something to write code for it? I'll be more detailed in the post. Posted: 31 Dec 2015 07:47 AM PST For example, an autopilot program on an airplane...does the programmer have to be fluent in the mechanics of flight or aerodynamics to be able to write the program? Or for weather modelling software does the programmer pretty much have to be a meteorologist to make it work? Etc, etc submitted by Young_Laredo [link] [8 comments]
