If there were only two objects in the universe, how would we know which is moving away from which? Or would we know? Posted: 29 Nov 2018 02:24 AM PST Let's say in the whole universe there are only 2 stars and they are moving away from each other at different velocities. Would we know each star's velocity without the reference point of a 3rd object? If they are rotating around each other to the point where they are always the same exact distance from each other would we even know, or as far as we knew they would be considered to not be moving/not have any velocity? If there were only one object in the universe, let's say me, am I effectively not moving, or would there be any way to tell I'm moving and in what direction? submitted by /u/liddieskeet [link] [comments]

To what degree can lungs repair damage caused by smoking? Posted: 28 Nov 2018 02:11 PM PST I'm wondering how this varies for different frequencies of smoking - and whether damage can repair at all. And, of course, how do you know/ what metrics are there, if any. Soz if wrong sub. submitted by /u/Molotov_Is_Dead [link] [comments]

Are there predators in the microscopic world? Posted: 28 Nov 2018 10:47 PM PST I've been thinking a lot about how life is sustained on earth by consuming. There are top predators all the way down the food chain such as this cat. I was wondering about microscopic world, are there any awesome predators in the microscopic world? submitted by /u/Ffaattccaatt2 [link] [comments]

Do we know anything of prehistoric fruits and vegetables? Posted: 28 Nov 2018 03:45 PM PST Are there any fossils of plants that were once edible or could be edible by humans today? submitted by /u/Red-Luft-Clouds [link] [comments]

How do they isolate the exact antibodies they want for an immunoglobulin shot? Posted: 28 Nov 2018 09:37 PM PST Apparently IVIG is just a bunch of random antibodies (which I'd also like to know how they separate that from blood). The immunoglobulin shot is specific. HOW do they get the correct antibodies they want out? submitted by /u/SecondTimePreggo [link] [comments]

Can two quanta interact with an electron at the same time in the photoelectric effect? Posted: 29 Nov 2018 03:29 AM PST I was studying the photoelectric effect at school the other day and I was wondering if two photons that do not have enough energy to eject an electron on their own, can interact with the electron at the same time and extract it out of the metal; unfortunately the teacher didn't know the answer....and couldn't find a concrete answer on the web. submitted by /u/Apaconcrack [link] [comments]

Is it possible to calibrate an optical instrument using the cosmic background radiation as a source? Posted: 29 Nov 2018 02:35 AM PST Have any spacecraft instruments been calibrated against the 2.725K CBR? If so, what were the main issues that had to be solved to perform such operation? I was wondering specifically whether It'd be necessary to cool the instrument below that temperature to be able to effectively measure the CBR without noise. submitted by /u/danilon62 [link] [comments]

Why did steam locomotives not push the trains? Posted: 28 Nov 2018 02:10 PM PST Steam locomotives produce a lot of smoke from the coal fire. That used to be an issue for the passengers on the train, especially in tunnels. It meant that in the first wagons, it was impossible to open a window without getting black smoke inside. So why weren't the engines pushing the train instead? submitted by /u/I-_-II [link] [comments]

How much natural gas is in a gas shale deposit? Posted: 28 Nov 2018 04:12 PM PST I don't mean how much natural gas reserves are in shale deposits, but rather, what is the grade of a shale gas reserve? If you were able to dig out the shale deposit from underground and look at it independent of the surrounding rock, how many cubic feet of gas would you get out of every tonne or cubic meter of rock? submitted by /u/fourthirds [link] [comments]

Is ALS more common today than in the past? Posted: 28 Nov 2018 11:59 AM PST I'm willing to consider the fact that we're just more aware of it as a society after the ice bucket challenge, but it seems much more common today. submitted by /u/tuuper25 [link] [comments]

What changes led to the massive polio outbreaks in the late 19th and early 20th centuries? Posted: 28 Nov 2018 10:16 AM PST Polio has been around for a long time, but this morning I learned that there weren't any (recorded) major outbreaks anywhere in the world before the mid-1800s...yet by the early 1900s there were paralytic outbreaks all over the world crippling thousands of children. I have been searching for explanations but, outside of a small number of anti-vax sites, I haven't found any (non-paywalled) attempts to explain what drove the switch from a slow drip of isolated cases to massive terrifying outbreaks. So...what happened? Do scientists suspect that a more dangerous strain emerged? Some change environmentally or socially? What made poliovirus so much more scary in such a short period of time? submitted by /u/djublonskopf [link] [comments]

Why is getting oxygen into the bloodstream bad? Posted: 28 Nov 2018 01:39 PM PST I heard that doctors would squeeze the syringes to get air out because they don't want air in the blood stream, but why is getting oxygen in veins bad? If a doctor gets oxygen into the bloodstream, won't it just diffuse into the blood and oxygenate the blood? submitted by /u/GangstaKev [link] [comments]

High-intensity ultrasound is being used to destroy tumors rather deep in the brain. How is this possible without damaging the tissue above? Posted: 28 Nov 2018 03:16 AM PST Does this mean that it is possible to create something like an interference pattern of sound waves that "focuses" the energy at a specific point, distant (on the level of centimeters in the above case) from the device that generates them?How does this work? submitted by /u/EPIC_BOY_CHOLDE [link] [comments]

For the universe, if the Big Bang were 12:00:00 on Jan 1, and the theorized Heat Death were 11:59:59 on Dec 31, what day/time is it now? Posted: 27 Nov 2018 08:38 PM PST I know comparing the time that has passed to the time that will pass is a very large number, but that's very hard for most people including myself to imagine. I'm hoping if we put it on a calendar scale it'll help. I mean, has it even been one minute yet? submitted by /u/hairy_butt_creek [link] [comments]

When battling a cold or flu, does taking drugs to ease symptoms impact recovery time? Posted: 27 Nov 2018 04:37 PM PST It's my understanding that the symptoms of cold and/or flu virus infections (hot flushes, sweating, excess mucus production, inflammation, etc) are the body's attempts at trying to eliminate the virus, alongside the immune response. When we take drugs to try and help reduce those annoying symptoms (paracetamol, phenylephrine, etc), are we interfering with the healing process and ability to overcome the infection? submitted by /u/NickEhlers [link] [comments]

Do other animal species experience the same right vs. left handed population differences as humans? Posted: 27 Nov 2018 03:43 PM PST So the other day I was wondering if other animals exhibit hand dominance like humans and read that other primates, kangaroos, and a host of other animals show signs of handedness. Then I started to think about human left handed trends, like how left-handed humans generally have shorter life spans and are GENERALLY more gifted in mathematics and music. In humans, there is a positive correlation between complications of birth and left handedness. Left handed humans are also more likely to break bones, get breast cancer, and suffer from heart disease. Do other animal species see these same differences between their right and left handed populations? I did a bit of digging and couldn't find anything myself, so I thought that you beautiful people maybe be able to help me out. PS. This is more of a zoology question than biology but this is the closes tag I could find :/ submitted by /u/FunnyMemeName [link] [comments]

Would Fermat have understood Andrew Wiley's proof? Posted: 28 Nov 2018 06:25 AM PST The math that Andrew Wiley used to prove Fermat's Last Theorem is more advanced than anything available in the 1600's. Would Fermat have understood Wiley's proof? If not, doesn't a proof of the theorem have to use the "technology" available at the time in order to be considered valid? submitted by /u/alt_romance_writer [link] [comments]

What is the History of Defining Water's Boiling Point? Posted: 28 Nov 2018 08:13 AM PST I heard a story years ago that I am struggling to remember accurately and I can't find online. The gist was that some famous (perhaps Greek?) scientist estimated the boiling point of water to be 90°C (obviously they weren't actually using Celsius :) ). The next person to come along measured it at 100°C and said, "Oh, but so-and-so is a great scientist. I must be off. Maybe I'll just report that I think the boiling point of water is 92°C." The next guy measures 100°C and says, "Those other guys can't have missed by that much. Maybe I'll report that I think it's 93°C." And so on, until estimates converged to 100°C. Does this ring a bell for anyone? I love the example as an illustration of systems learning slowly, for better or for worse, but I wish I knew both the details and the truth of the story. Any help is much appreciated. submitted by /u/Doctor_Underdunk [link] [comments]

Why can’t we use food as energy? Posted: 27 Nov 2018 10:52 PM PST We live off of food. All of our energy comes from food. All of our motion is fueled by the food we eat. And our body temperature is due to the burning energy we get from food. So why can't we use food to fuel other things like say a car. Why can our body tear food down to energy but we can't build a device that basically does what our body does, tear food down to energy. submitted by /u/5dwolf20 [link] [comments]

Why do we see hydrogen's spectral lines in absorption in the sun's spectrum? Posted: 27 Nov 2018 04:08 PM PST Why are hydrogen's wavelengths missing from a star's spectra. Does it have something to do with the gas enveloping the sun? submitted by /u/TheArmChairGen [link] [comments]

Why does food get crispy when you cook it longer? Posted: 27 Nov 2018 04:06 PM PST For that matter what actually happens when you cook food? I hardly know anything about cooking, but I was making some food earlier and just had this thought. I really only think of it as heating food up, potentially combining ingredients and things along that nature. However I don't get why it would change just from heating it up. Can someone please explain. submitted by /u/afediukov [link] [comments]

Out of my depth. My nephew is trying to figure out how a cell phone speaker works, what powers it, how does it connect so tiny? He's 14, how do I explain this? Posted: 27 Nov 2018 09:49 AM PST He's interested in taking things apart. Right now he has an older phone I think it's an iPhone 6? He found the speaker assembly, and used ifixit to identify the other parts. But he wants to know how to make it work apart from the cell phone. How can he hook the speaker up so it plays from a bluetooth source? I have a soldering iron, but that's as useful as I can be.

Are humans getting taller? Posted: 26 Nov 2018 01:06 PM PST I've read that Americans, on average, have stayed the same height for the past 50 years. Is this true even now with the amount of immigration from Latin America and Asia where people tend to be shorter on average? Are millennials taller than their parents?

Could a substance get so hot that it behaves relativistically? Posted: 27 Nov 2018 06:49 AM PST If temperature is a measure of the kinetic energy of the particles in a substance and we can calculate the root-mean-square velocity of those particles, then hotter substances contain faster-moving particles.

Is there "air resistance" in space? Posted: 26 Nov 2018 11:48 PM PST Yes, I understand that space is a vacuum and that there isn't actually air out there. That being said, I was reading about the interstellar medium and nebulae and was wondering if the density of space would affect the speed of an object going through it. For example, would there be any noticeable change in velocity of the voyager probe as it left our galaxy and entered interstellar space? Or what if it was on course for a particularly dense nebula? The more of this that I'm typing out the more questions I have. I assume that light would also be refracted through a denser part of space as well- so is that also the case? submitted by /u/Foxmod [link] [comments]

Why are fast breaths cooler than slow breaths? Posted: 27 Nov 2018 08:30 AM PST If temperature is average kinetic energy, why is it colder when I blow air out quickly and warmer when I blow air out slowly? Shouldn't the faster air have a higher overall kinetic energy and therefore a higher temperature? submitted by /u/ApePac [link] [comments]

How realistic fiction portrayal of extraterrestrial decoded humanity's digital radio communication?

How do carcinogens cause cancer? Posted: 26 Nov 2018 10:41 AM PST As I understand, cancer is caused by mutations in DNA. I can see how UV light or radiation can cause a mutation by directly damaging the DNA. But how does an exposure to certain chemical cause cancer? Shouldn't most chemicals be stopped by cell membranes? Or when ingested, wouldn't they normally broken down in the digestive tract before getting into the bloodstream? Also, if a chemical can go all the way into cell nucleus to damage DNA, wouldn't it also cause other kinds of damage, causing cell death? submitted by /u/IndependentGuy [link] [comments]
