considering that the pistol shrimp can produce heat almost as hot as the sun just here on earth... http://en.wikipedia.org/wiki/Alpheidae
I don't think heat would be an issue if it's just a millisecond like that. However, the gravitational pull even for a millisecond might ruin earth or alter the seasons and cycles by throwing it off course.
>>550805020 I think you underestimate how much heat and radiation our bitch ass would get if we were that close to the sun. The atmosphere on the side closest to the sun would get blown right the fuck off while the dark side got to experience that enjoyable feeling of all the air catching fire at once.
In order for us to be aight, we'd need to be there for less than a microsecond.
>>550804825 >crack apart from the gravity nigga lrn2physics
mass doesn't just disintegrate when near a much larger group of mass. it merely is attracted.
it may possibly disrupt gravitational pull all over the earth, squashing people, cars, knocking over buildings, etc...
>>550804341 OP, UV radiation and solar wind would tear everyone to shreds. pick a shorter, more interesting duration, say a nanosecond, or a picosecond.
>>550805020 You are literally and idiot. Humans can sense a basic change of light or sound over the duration of 5 milliseconds with ease. If the Sun was present for 1 ms, it would still be EXTREMELY noticeable. 1 ms is an incredibly long time in physics.
No, literally. The Earth would boil, the atmosphere would disintegrate, and it's short duration of gravitational pull would rip skyscrapers, buildings and trees sideways, crush cars and houses, possibly liquefy organisms, etc.
>tl;dr ITT: /b/tards that think that 1 ms is a very short amount of time.
>>550805421 Yeah, I can't work out the tidal forces, but the earth alone heats up and affects the moon from the difference in the gravitational pull between one side and the other. It would probably trigger some insane earthquakes at least. Also, the effect of gravity travels at the speed of light, so in a millisecond, the effect will only have traveled 299792 meters (299 Km) by the time the Sun returns and The average distance from Earth to the Moon is 384,400 km. This might mean the effect won't be full blown and will only pass in a millisecond wave.
Does the earth have a set amount of water that's been recycled from the beginning of it's existence? If some dickass aliens dropped by and took a decent amount for themselves, would the earth have a way of recovering it?
>>550807206 There would have to be some sort of shockwave, consisting of whatever gasses are thrown out by the explosion. Of course, that isn't what would destroy us. Most likely we'd succumb to the effects of gravitational changes. Thus, would the change in gravity actually affect us before the light of the event itself?
>>550807349 There is essentially a set amount of water forever, yes. Meteorites are the only way, normally, that new material gets added to Earth, and they're not made of water. Comets are. If a comet hit the Earth we'd get new water. But if a comet hit the Earth, that would be hella bad news.
>>550806671 It doesn't matter what distance it is away from the Sun, it's going to stay a rock until other variables change that state (i.e. Temperature, Collision...)
Just like asteroids, retard.
Bodies of rock don't just explode before hitting a much larger celestial body due to gravity. In fact, due to centripetal force, it is more likely to be under even further compression (clouds condense into planets for this very reason).
The only explosion that could happen is the disintegration of the terrestrial body due to temperature levels. Whether or not the distance from the moon away from the Sun is enough to annihilate the Earth into dust, well... the answer would help solve this thread's debate a lot, now wouldn't it? I'm not a fucking astrophysicist. Go fuck yourself.
I'm not pretty sure, but i think that from that distance, it would be the end of earth.
I mean, the ultimate gravitional pull of the sun would rip the earth in pieces, also the amound of energy would be so great from that distance, it would burn every thing that lives, evaporate all water and burn all oxigen.
All of this happens in less than 2 seconds (because of the distance)
>>550806152 Look at the power output, dumbass. We're talking a 1/1000 of a second. Comparing the distance from the sun to the moon, we'd receive roughly 152100x the amount of energy we usually do for one millisecond. The earth receives roughly 1400 W/m^2 of energy from the sun. So for a single square meter, it normally receives 1.4 J/m^2 of energy each millisecond. Multiplying that out, all visible portions of the Earth will receive about 213 kJ of energy per square meter. This is enough energy to raise 51 kg of water by 1 degree C. Water's density is 1,000 kg/m^2. It could only raise .051 m of a 1 m^2 patch of water by 1 C if all of the light were absorbed.
It wouldn't have as big of an effect as you think. The biggest threat would be the atmosphere turning into a giant flash bulb for an instant.
>>550806671 >Gravity on one side of the earth would be stronger than the other
And what is your evidence for that?
It would be to an extent, but the difference in gravitational pull between the far side and the sun-facing side would not be enough to cause it to somehow "pull apart" just because one side would be accelerating in relation to the other if they were totally split and separated.
But they're not. They're one piece, pulling and tugging on itself to go in a particular direction. The sun isn't as strong as a black hole, it's not going to be spaghettify.
>What's that? >Spaghettification actually maintains the body as one consistent, strung-out object?
Well if a black hole can't spontaneously disintegrate a body of mass, how the fuck can the sun?
>>550806671 The difference in gravitational potential would be minor due to the immense size of the sun. The only thing that it will do is result in 1 m/s of immense gravity pointing towards the sun that affects everything almost equally. It wouldn't really have a shearing effect.
>>550809362 I couldn't say. Powerful gravitational waves are hard to come by. I'm pretty sure it would merely be the effect that I mentioned in the post above you. The overall influence on the Earth's orbit would be restricted to that .001 seconds, so it wouldn't be too major despite the magnitude of the effect.
>>550808941 >Calculates raw energy >Badly >Doesn't take into account UV radiation >Doesn't take into account solar winds >Both of which would disastrously ruin your poor Rebbit excuse for a theory >Doesn't take into account the surface area of the sky occupied by the sun
You're doing those calculations based purely on distance. >152100x >Took the distance from the sun to the earth >Divided by the distance from the moon to the earth >Failed trigonometry and geometry in the process
>>550804341 Many things would happen simultaniously. -gravity would pull Earth out of its current orbit (there's a chance 1 ms would be enough for them to collide) -corpuscular radiation would be too dense for Van Allen belts to stop so we'd see aurora all around us and tiny dots would flash in front of our eyes... -...if we wouldn't be blind by then because visible light... -...but, more importantly, if we weren't evaporated due to some 5000 K heat In the meantime, the atmosphere ignites and gets blown away thanks to the copuscular radiation mentioned above (trade name: solar wind) along with the now gasous water -finally, the crust blows up due to thermal elongation and the remains of our beloved planet start orbiting their killer The chunks remain white-hot for a couple of thousands of years because vacuum has no thermal conductivity. Some pieces may turn into comets far, far away.
>>550809810 It's a rough figure for a rough scenario. Also, the calculation should at least somewhat similar to the actual numbers. I squared the difference in the distances as per the inverse square law, so the flux figure should be somewhat comparable to the actual figure. This also accounts for the amount of the sky that the sun occupies.
I'm assuming no major solar activity since that would be completely random and unnecessarily complicates the scenario.
It's obvious from your post that you aren't all that proficient when it comes to physics and math.
>>550810305 I don't know anon. You might wanna check your calculations >sun distance from earth to moon >1 ms >enough time for the earth to fall into the sun's surface >implying earth could move faster than the speed of light
The fucking. Light. It takes 1500 ms to get to the Earth from the Moon.
That means it would take >1500x the amount of time you suggested it could take.
>meaning all of your other opinionated "extrapolations" are shit
you could also use the raw energy output of the sun 3.8×10^26 J/s then use a simplified calculation (earth absorbed) = (sun emitted)*(earth area)/(sun area) distance is ignored 3.17*10^22 J/s divide by 1000 for miliseconds 3.17*10^19 J that is a lot of energy approx 100 x larger than krakatoa and 10^5 x larger than the earth's normal solar absorption during the same milisecond
>>550811107 Yeah, but now that I think about it, I'm actually wrong. There's a constant output of energy from the Sun, so you'd immediately receive the radiation that was there, at that moment, one moon-distance from the Sun.
>>550810305 It wouldn't affect the earth's orbit because sun's surface gravity is only 274 m/(s^2). 274 m * (.001^2) = 274 m * .000001 = .000274 m = .274 millimeters. The primary concern is atmospheric heat and even then it should be small, since I don't remember chemistry I'll leave it to someone else to calculate the mass and heat capacity of the atmosphere and see how much the sun would heat up the atmosphere, but again, I bet it's minuscule. EMP might be a factor though. We wouldn't even notice it, and there would probably be conspiracy theories about aliens messing with the technology
>>550812617 Close to the sun: 3.17*10^19 / 1.47x10^17 = 215 J/m^2 each millisecond.
Far from the sun: Using Wikipedia values for flux on Earth. 1413 W/m^2 = 1.413 J/m^2 each millisecond.
>>550813037 The density of light lessens the further away from the source of light. That's what causes the difference in energy received. Imagine light branching out in a sphere. The bigger than sphere, the more area that energy has to be spread out over.
interesting. in general i would say that we would be fucked: a) the total radiation that we receive on earth from the sun scales as : 4 * pi * r^2 . r is the distance (so it's the spherical surface. since earth-sun distance is 412 times earth-moon distance, (3 orders of magnitude) and the whole this is squared we are talking about a sudden 9 digit increase in radiation. After that with the stefan's law I=sigma* T^4 we can estimate that we will get an at least 2 orders of magnitude larger temp. so ... 2 digits more temperature for 1 millisecond. that's hot man.
b) gravity! i can't even. all the tidal forces that will be developed for that sweet millisecond are going to finally get rid of the cancer on this board. the scorched rocks that this earth was once, will have to deal with a pretty sexy amount of sudden acceleration and they would sligshot the fuck out of our trajectory
>>550813037 doesn't that require the assumption that the energy is being released from a single point as apposed to a large sphere or near flat surface which is the case with the relative sizes and distances of the sun and moon
>>550813343 gravity travels as waves, the distance between the earth and the moon, even at the speed of light, is more than a millisecond; there would be no effect whatsoever except from the previous radiations from the sun already on their way, hence cancer
>>550813670 sure. but OP didn't ask what would happen IN the time of that millisecond. now---sun comes over-*1ms*-sun leaves--we get hit by the first wave-*1ms*- second tidal waves comes in---ripples keep fucking us---endofcancer
>>550804341 I imagine we'd get sucked into the sun eventually. Something people keep missing is that our solar system and entire galaxy is still moving through the universe. If the sun teleported to us, I imagine it would give us a massive gravitational pull towards it. Then, it would return to it's original location - but keep in mind, the original location would no longer be the center since the solar system has moved with respect to the universe.
There would be a smaller gap between us, while we accelerate violently towards the sun.
>>550812617 r = earth radius R= sun radius d = distance fi = the solid angle the earth covers
fi=2 asin(r/(r+d+R)=0.006 rad being fi small we can assume the area of earth exposed to radiation is not much different than pi*r^2 at a distance of (r+d+R). So the radiation that goes to earth is (3.8×10^26 J/s)*((r/(r+d+R))^2)=1.326x10^22 W. Wich gives 1.326x10^19 J
even with distance it's that big. Earth average absorption is 10^14 W, so 10^11 J/ms
>>550813340 my number has no per area units just total energy meaning that either 1.47x10^17 is not a ratio but an area which it cant be because the surface of the earth is 5*10^16 m^2 if you aren't doing proper unit conversions your end result is essentially useless
>>550804341 Gravity and heat would wreck the Earth. Solar System might be thrown out of alignment. Think about the strength of our star's gravitational pull, it's what keeps all 8 planets together, as well as Pluto, the asteroid belt, and God knows how many orbiting rocks.
>>550816150 >confusing heat (state of excitation) what? that is like >confusing constitutional literalism (anchovies) with current supreme court doctrine those things cannot be compared or confused heat is by definition energy transfer (radiation, convection, conduction) there is no stationary heat nor excitation heat the words you are looking for are temperature or possibly molecular kinetic energy
What would happen if a sun made of ice would collide with the normal sun, which is made of lava? Both suns are same size, and the sun made of ice is at -1000 Fahrenheit, and the normal sun is at +1000 Fahrenheit.
Would their temperatures cancel each other and leave only empty space, or would they leave a zero degree sun?
>>550817739 there is a real answer to this troll question ice is weak-sauce and cant stop the unlimited baseness of the sun after weird collision period there would be a new sun with twice the mass nothing else would change
>>550816862 >https://en.wikipedia.org/wiki/Thermal_radiation Sorry to break it to you, but that's not really relevant. The Planck curves show the relationship between temperature and wavelengths of emitted radiation in a black body. Besides, heat isn't the same as radiation. Heat refers to the amount of movement on a molecular level, whereas radiation refers to, well, electromagnetic fields. They're intimately connected, as you can see from your link. Specific temperatures give off specific amounts and types of radiation, and radiation can, due to its energy, be transformed into heat once it hits something (say, the atmosphere or the earth's surface).
It would, however, get really hot in any case. The only reason the sun heats the earth now is due to radiation, and that wouldn't change just because it got closer. On the contrary, seeing as how radiation propagates according to the inverse square law, the sun being at the distance to the moon for even a millisecond would throw so much radiation at earth it's almost unfathomable. So in any case, the side of the earth facing the sun would most likely get toast after the 1.3 seconds it takes from light to travel from the moon to the earth.
>>550819805 Well, that guy's wrong. If we assume the sun teleported here and went away in AN INSTANT (a planck time, I suppose), the earth would be accelerated towards the sun at a rate of 3.318*10^8 m/s^2. This rate would increase as it got closer to the sun for that millisecond.
Depending on where the sun faces the earth, we'll either get fucked out of orbit or accelerated inwards to the sun and either find a new orbit or get sucked into the actual sun. Yay.
