| Posted: 10 Feb 2020 06:29 AM PST the scene where they visit the waterworld-esque planet and suffer time dilation has been bugging me for a while. the gravitational field is so dense that there was a time dilation of more than two decades, shouldn't the planet have been pulled into the blackhole? i am not being critical, i just want to know.

| How does tungsten bond with carbon to produce Tungsten Carbide? Posted: 11 Feb 2020 02:12 AM PST Is it a type of metallic bond or ionic bond? I'm not sure about how it bonds together. [link] [comments]  |
| How does heat capacity relate to heat conductivity? Posted: 11 Feb 2020 02:07 AM PST I'm having a hard time reconciliating between these to two concepts, as far as I understand a material with low heat conductivity will impede the flow of heat but doesn't that also mean that it takes more effort (energy) to heat up that material? I don't understand how a material could have a low heat conductivity but not a high heat capacity. [link] [comments]  |
| Are there electrons in neutrons? Posted: 11 Feb 2020 01:47 AM PST During Beta radiation a neutron (according to our teacher) basically turns into one Proton and one Electron, the proton stays in the atom and the electrons gets sent out. is this correct? Where does the electrons come from? [link] [comments]  |

| Why do we raise our hot drinks? Posted: 10 Feb 2020 08:44 PM PST So I was on the shuttle to school the other day, and I had a fresh cup of coffee. I saw we were approaching a speed bump and I instinctively raised my coffee higher in the air as we went over said bump. I then realized that many other people do the same thing to sort of brace for any incoming bumps if that makes sense? Can someone give me the physics or logics to why we do this? Thanks [link] [comments]  |
| Which mountain could overtake Everest? Posted: 10 Feb 2020 08:40 PM PST With the constant geologic forces, is there a mountain that could overtake Everest as the highest mountain in the next 10,000 or more years? [link] [comments]  |

| Is there a simple method for differentiating between genera of actinobacteria? Posted: 10 Feb 2020 08:54 PM PST I'm in a second year microbiology course trying to ID a culture isolated from a local dirt sample. I decided to try to ID one of the filamentous colonies that grew despite the course being geared towards more basic organisms. I've determined that my culture is an actinobacteria, and I suspect that it's within the genus Streptomyces (based on morphology). However, I can't seem to find much literature on methods of confirming that it's a type of Streptomyces within my means (or even exactly what it is that makes a species Streptomyces and not another type of actinobacteria). I have access to a phase contract microscope (up to 1000x), various selective and differential media, some basic biochemical tests, and solutions to make most commonly used stains. I do NOT have fluorescence microscopy or any genetic analysis equipment (or experience). I've learned everything I know about actinobacteria in the last 3 days, but from my understanding, they're incredibly diverse. Due to the ridiculous variety in colony formation, morphology, structure, and biochemical function within actinobacteria, I'm having difficulty discerning the genus of my culture. Is there any specific differentiating morphological trait between genera, or any series of stains or growth conditions? [link] [comments]  |
| Why does GPS use so much power on phones? Posted: 10 Feb 2020 02:35 PM PST Using location services is known to be a battery hog on smartphones. But if my understanding of how GPS works is correct, it seems like the smartphone never transmits any radio signals: your phone simply listens for broadcasts from GPS satellites and computes its position from the data they transmit. I can't imagine that the calculations are all that intense, and antennas are passive devices. Why then does GPS use up so much battery power? [link] [comments]  |
| Specifically how do scientists identify viral DNA in the human genome? Posted: 10 Feb 2020 01:15 PM PST I have heard the claim that humans have some odd 2-8% viral DNA and that some of this DNA is shared across species, I am curious how scientists actually determine what is viral DNA and what's not.

| Orbiting Moon at low altitude , how low can we go and would there be a point? Posted: 10 Feb 2020 01:15 PM PST Since there is no atmosphere on the moon to slow down a ship, is it possible to orbit the moon at a very low altitude (say several to several dozens of meters)? How fast would the ship go? And would there be a point to do this either for one ship or for a constellation? [link] [comments]  |

| Why do we need multi-stage rockets to get to space? Posted: 10 Feb 2020 07:24 AM PST I recognize that it takes a lot of energy to get to orbit, but why do we need more than one type of rocket? To dumb it down a bit, what's wrong with one big rocket that powers you all the way? Or two of the same rocket? [link] [comments]  |
| Posted: 09 Feb 2020 10:21 PM PST Cell replication, as far as my freshman, non-biology-major coursework puts it, is a cell making copies of itself based on instructions passed down through generations. How does the cell, the organ, and the body age if they are constantly being replaced with new copies on the cellular level? As a side question, what organ(s) would last the longest if they were able to run independently? Which organs or parts of the body wear out the fastest? [link] [comments]  |
| Posted: 10 Feb 2020 07:41 AM PST We know that vaccination doesn't have 100% efficacy; my question is aimed at the 5%+ of people who the vaccine doesn't induce immunity in. Is this group of people still susceptible to the effects of these disease in all its horrific glory (i.e. sterility, encephalitis, deafness, pneumonia, etc.)? Or are they still susceptible to infection but far less likely to develop complications? [link] [comments]  |
