- The cosmic microwave background radiation is radiation that has been stretched out into the microwave band (It went from high frequency to low). Does that mean it has lost energy just by traveling through expanding space?
- What led Socotra Island to having such unique flora when it is less isolated than, say, Easter Island or St. Helena?

| Discussion: Veritasium's newest YouTube video on the reproducibility crisis! Posted: 11 Aug 2016 07:01 AM PDT Hi everyone! Our first askscience video discussion was a huge hit, so we're doing it again! Today's topic is Veritasium's video on reproducibility, p-hacking, and false positives. Our panelists will be around throughout the day to answer your questions! In addition, the video's creator, Derek (/u/veritasium) will be around if you have any specific questions for him.

| Posted: 11 Aug 2016 06:16 AM PDT That is my understanding of the CMB. That in the early universe it was actually much more energetic and closer to gamma rays. It traveled unobstructed until it hit our detectors as microwaves. So it lost energy just by traveling through space? What did it lose energy to? [link] [comments]  |

| Why did the Olympic pool go green and why was it so quick? Posted: 11 Aug 2016 01:08 AM PDT http://m.bbc.co.uk/sport/olympics/37029833 That article mentions Alkaline. How does that affect the colour? And would it really be safe? [link] [comments]  |

| Posted: 10 Aug 2016 11:03 AM PDT I have an engineering degree level of physics understanding and am not religious so there is no need to address concerns regarding physics possibly being "unnatural". https://www.quantamagazine.org/20160809-what-no-new-particles-means-for-physics/ [link] [comments]  |
| Could we use CRISPR to create a more efficient CRISPR? Posted: 10 Aug 2016 03:38 PM PDT I was watching this video on CRISPR and my mind wandered to computer language compiler, where the first compilers may be ineffecient, but eventually they get better. Could we enhance our own genes to make this system more efficient, or at least with more "features"? [link] [comments]  |
| Why, in terms of an energy transfer, forces, and molecular structure, do brittle objects shatter? Posted: 10 Aug 2016 07:02 PM PDT Say I dropped a glass on the ground and it broke. Did it break because its own weight exceeded the ultimate compressive force of the glass? Is it because the equal and opposite force from the ground to the glass as it hit would somehow rupture the bonds between the atoms of the glass, thus ruining the structural integrity? Something else? [link] [comments]  |
| Expansion of the subreddit rules on AMA's Posted: 10 Aug 2016 02:15 PM PDT Hello all! We are expanding our rules to better encompass AMAs. Our AMAs are something we've been growing over the last few months and expect to keep growing in coming months and years. We want to make sure we have guidelines set out for those specific posts, and have updated the rules to include AMAs. Here are the updated rules list for the subreddit If you have any questions please feel free to ask them here. [link] [comments]  |
| What was the average temperature on Earth during the Cretaceous Period? Posted: 10 Aug 2016 09:22 PM PDT |
| What is the difference between Embryonic and Fetal stem cells? Posted: 10 Aug 2016 03:19 PM PDT In addition, how are they both extracted/obtained for research Background: I'm a student and am working on a project about the ethics of Stem Cell research. I'm trying to get a half decent understanding before I have to write my paper :) [link] [comments]  |
| How much would life on Earth change if the Earth's axis was tilted at 24 degrees? Posted: 10 Aug 2016 10:59 AM PDT Unsure if this is repost, but I woke up this morning thinking about this. I've read articles and watched documentaries about how drastic of a change Earth would experience if it was x feet closer/farther away from the sun, or if it spun x miles faster/slower. Would there also be a drastic change to life on Earth if it were tilted .5 Degrees more? [link] [comments]  |
| Are there any Miller-Urey-type experiments that are currently running continuously? Posted: 10 Aug 2016 01:51 PM PDT Hello, I have always been fascinated by experiments simulating the early times on Earth trying to answer the question of how life first arose. I was wondering if any of you know about Miller-Urey-type experiments that focus on running the experiment continuously and analysing the chemical composition at time intervals trying to create some primordial-like soup by performing a longer (in relation to time) experiment?

| Posted: 10 Aug 2016 12:48 PM PDT I know some birds are surprisingly smart so I just wanted to know how they handle that situation. [link] [comments]  |
| Why is the domain to f(x) = x^x only positive numbers? Posted: 10 Aug 2016 11:34 PM PDT When I ask Wolfram Alpha what the domain of f(x) = xx is, it tells me that it's only positive numbers. This seems odd, though, since the function is defined for some negative numbers (e.g. [-2]-2 = 1/4). Does a function's domain generally exclude numbers for which it's define? Is WA right about this, and if so why? [link] [comments]  |
| Is there any actual scientific evidence for such a thing as severe pornographic addiction? Posted: 10 Aug 2016 09:23 AM PDT I was curious about how the brain reacts to pornography and If it behaves similarly to other addictions. When I tried looking up the subject matter a lot of christian help websites came up in the search list. I'm not looking for a religious answer, all I want to know is if pornographic addiction is an actual thing and, if so, how the brain reacts on and off of porn. [link] [comments]  |
| Are non-commuting variables always Fourier transform duals? Posted: 10 Aug 2016 03:26 PM PDT The intuitive explanation of the Uncertainty Principle usually involves thinking about a wave packet in both position and frequency space. This makes sense for position/momentum, but it's hard to visualize for something like orthogonal projections of intrinsic spin. Can the latter be represented as Fourier conjugates, or is the Fourier interpretation of the commutation relation peculiar to position/momentum? [link] [comments]  |
| Where are asteroids and comets coming from? And where are they going? Posted: 10 Aug 2016 07:03 PM PDT |
| Posted: 10 Aug 2016 08:30 PM PDT Despite quantum physics still being a theoretical branch, many of us speak as if characteristics/theories of quantum physics are laws that can be used to explain phenomena of classical physics. To what extent do we use theories of quantum physics as bases for explaining classical physics? [link] [comments]  |
| Does time dilation affect the propagation of gravity waves? Posted: 10 Aug 2016 12:20 PM PDT I understand that gravity waves propagate at the speed of light, and I understand that extreme gravity, like a black hole's erogosphere, can bend spacetime faster than the speed of light. Are gravity waves affected by time dilation since it is itself a form of gravity? Could an extremely strong gravity wave affect itself? [link] [comments]  |
| Are certain bases easier to find prime numbers? Posted: 10 Aug 2016 07:52 PM PDT I did a quick search, but most of the inquiries were about whether a prime remains prime whether the base changes (spoiler - it does). I saw something strange that indicated that primes represented in base 10 have a higher probability of ending with certain digits. I guess this doesn't do much because now instead of guessing primes you guess bases that have better prime patterns and then you still have to guess at primes, but it also leads to the question of is there a certain base we are better at finding prime numbers with? I guess base 2 makes sense given it's native to numerical computation (transistors being on or off). But maybe outside of pure numerics there's some magic prime base that works best?
