| Is there a tidal effect on our atmosphere? Posted: 21 Jun 2017 12:50 AM PDT So I understand that the sun and moon's gravity creates a tidal effect on the oceans of our planets, but do they cause a similar effect on our atmosphere? Or is it not dense enough? [link] [comments]  |

| Do Prime numbers change with base? Posted: 21 Jun 2017 05:13 AM PDT E.G., we use Base-10, but would there be different prime numbres in base 12? 20? 99? [link] [comments]  |
| Posted: 21 Jun 2017 06:35 AM PDT Also, what would happen if said material was placed in a low gravity situation, such as on earth? [link] [comments]  |
| 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. [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? [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?

| Posted: 20 Jun 2017 04:47 PM PDT Assuming that pressure isn't an issue would a large tungsten(or similar) vessel be able to contain a meltdown, or is a nuclear meltdown hot enough to melt pretty much anything? [link] [comments]  |
| 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. [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?

| 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.. [link] [comments]  |

| 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. [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? [link] [comments]  |
| Why is a halogen more electronegative than it's halide? Posted: 21 Jun 2017 02:28 AM PDT I tried asking my chemistry teacher why Cl2 was more electronegative than Cl- but wasnt able to understand her explanation. Help would be appreciated! [link] [comments]  |
