| What are the fastest accelerating things we have ever built? Posted: After seeing a reddit post in where a rocket (or missile) accelerates to Mach 10 in 5 seconds, I now have the question if there is anything similar or faster than this. Edit: Link to the gif: http://i.imgur.com/l7v5FzZ.gifv The title of the gif states that the missile is accelerating with 100g. [link] [comments]  |

| Posted: Another way of thinking of this is whether the escape velocity varies with the angle of travel relative to a stable orbit or the planet surface. [link] [comments]  |

| Can the Uncertainty Principle break down in superposition? Posted: This may be terribly misinformed or fundamentally flawed query that belongs on ShowerThoughts, but can someone explain the outcome of the following scenario? Consider a single instrument that is capable of measuring both the momentum and position of a single particle asynchronously (For added entertainment, imagine it's a cat). The instrument's function fluctuates between the two states, never possessing both simultaneously. The condition of these fluctuations is a switch, the position of which is affected by the readings from a geiger counter positioned next to a sample of a radioactive substance. If this instrument were to be positioned so as to measure the momentum and position of a given particle in an alternating and random fashion, would the particle's momentum and position be known with equal precision albeit in a state of superposition, thereby defying the uncertainty principle?

| Do Gravitational Waves Satisfy the Wave Equation? Posted: Recently started learning about waves and their associated wave functions, and I believe my lecturer said "all simple waves should satisfy this equation". Though Gravitational waves are no way simple, would they still satisfy it in some way or another? [link] [comments]  |
| Is 10^80 an accurate representation of the amount of atoms in the universe? Posted: I saw a post about how Google developed an algorithm to beat world championship 'Go' players. One person interviewed said "there are more board configurations of 'Go' than are atoms in the universe." I researched it further and sure enough a lot of sources say the estimated amount of atoms in the observable universe is estimated to be around 1080. That's an incredibly huge number, however, I don't buy it one bit. Considering that the observable universe is 46 billion light years in any direction from us, I can't believe that 1080 is an accurate representation. Is this accurate? Is there a concept I might be missing or misunderstanding? Am I underestimating 1080? [link] [comments]  |

| How does radiation from the sun compares to radiation from a wi-fi router? Posted: I'm having this discussion where I said that being out in the sun for one minute is much more harmful, in terms of radiation, than living with a wi-fi router in the house for a year. Now he wants citations and proof, but I can't find anything online that compares radiation from the sun and wi-fi routers. Thank you! [link] [comments]  |
| Is it possible that a great flood, similar to the story in the bible? Posted: Obviously I'm not saying that the biblical account is historical truth but I was wondering if there was any scientific, probably geological, evidence to show there was a massive flood (most likely regionally). This came about as I was looking into different mythologies which all talk about a great flood of sorts. this takes place in hebrew, greek, egyptian, some native american, and many other mythologies. I figured if there was a story about it in so many mythologies then it probably came from an actual event that took place. EDIT: I took out the term globally because even before this got posted after mod approval I figure Global was already out of the question because when thinking about an actual cause for it, my thinking being a massive tsunami, i figured the closest the world has probably come to that was probably before the advent of humanity (as in like the idea of a giant meteor that wiped out the dinosaurs). I wanted to stress the idea of massive catastrophic regional floods. Plus people love to attack the global idea and forget the regional. EDIT: Thank You for all the answers. [link] [comments]  |

| Posted: In my head, I've been playing with a model where I fall through the gravitation of the earth. I'm assuming I managed to dodge all the individual particles as I fall, so that I'm not stopped by smashing my head into the ground. Also obviously assuming I'm not going to die from it. So usually when people answer this question (which is usually demonstrated as a hole through the earth so that you're not obstructed), you fall past the center until you're near the surface on the other side, and you bounce back between the two sides getting further from the surface each time until you eventually settle in the middle of the earth's gravitation. But I was thinking, what about the gravitation of the particles around you, such as the gravitation of the particles in the atmosphere, crust, oceans and mantle - even though the earth as a structure would attract you towards the center, wouldn't the gravity of these regions also affect you as a gradient, thus changing the path? Sorry if this is a wrong way of looking at it, feel free to correct me. [link] [comments]  |
| Why isn't molality more common than molarity? Posted: I often seen molarity used to describe solutions all the time, and molality only as a problem for just number crunching practice. I even see %mass used more often than molality. I used to think molarity seemed like the better measurement to use, but the more I think about it, the more molality seems to be the better measurement. It seems like it would be more accurate to prepare solutions by molality vs molarity due to molality being density-independent, along with molality being used to calculate effects like boiling/freezing point elevation/depression.

| Why will the Smith Cloud cause stars formations, after entering the Milky Way? Posted: A sparse cloud of gas enters the area with a more dense distribution of matter (do i understand galaxies right?) - why would it cause a And why is it called [link] [comments]  |

| How much energy would be needed to make the Ocean Boil? Posted: Since salt increases the amount of energy/temperature that is needed for water to boil, and with the high concentration of salt in the ocean, how much would be needed for it to reach its boiling point? Could you measure on a smaller scale with the same density of salt as the entire ocean? Someone in a speech today said "you cannot boil the ocean" and it made me think of how much it would take.

| Is eating a raw diet the healthiest method of sustinence? Posted: Aka a largely vegan diet? I've heard this argument a great deal from vegans. As well as the argument that "we aren't supposed to eat meat" I.e. "Meat eating is unnatural". [link] [comments]  |
