| Do magnetic and/or electric field have any influence on time and space? Posted: 19 Aug 2018 06:22 AM PDT According to Einstein, gravity has influence on space and time. Does magnetic field have influence on time and space? Does electric field have influence on time and space? [link] [comments]  |

| How was the age at which the universe became transparent calculated? Posted: 19 Aug 2018 01:01 AM PDT I'd curious about the most accurate primary source regarding such data & calculations, thanks. [link] [comments]  |

| Do large Earthquakes risk setting off other nearby faultlines? Posted: 18 Aug 2018 06:47 PM PDT For example, when the Cascadia Subduction Zone next goes, it's supposed to cause a truly massive earthquake... Will this increase the likelihood of a major earthquake in California? Or if there is a major Earthquake in Fiji, like just happened, does that impact the opposite side of the tectonic plate? Or am Imagining the plates as much too rigid? [link] [comments]  |

| What chemical compound contributes to the classic "campfire smell?" Posted: 18 Aug 2018 07:58 AM PDT Referring to the smell that clothes sometimes take on when they're exposed to lots of campfire smoke. [link] [comments]  |
| Posted: 18 Aug 2018 07:22 AM PDT Is it possible to have them black or some other color? (maybe for a fantastical humanoid if not for RL humans?) [link] [comments]  |
| What is the status of the search for room temperature superconductors? Posted: 18 Aug 2018 11:18 AM PDT I know a few years ago there were some relatively promising advances using cuprates. I read something about gold and silver having room temperature superconductivity recently, but that seems implausible based on my experience with materials, and the noise patterns observed in their testing. What is currently the most promising path, and have there been much in advances since they reproduced a superconductor at 203 kelvin? [link] [comments]  |
| Why would animals share self-harming information? Posted: 18 Aug 2018 08:09 AM PDT I read that dogs have anal glands that release smells which give information to other dogs about their health. So other dogs can decide if they would want to make acquaintance but wouldn't natural selection make it so that all dogs would give out 'good' smells even if they were unhealthy just to get a chance to reproduce? Is there an evolutionary advantage to sharing honest information that reduces the individual's opportunity to pass on his genes? There must be similar examples in other animals as well.

| How do electron 'standing waves' relate to the probability density cloud? Posted: 18 Aug 2018 07:33 AM PDT Let me try to explain what I've sort of understood thus far:
My first question might be a little dumb-sounding, but how does de Broglie's model account for the electromagnetic radiation of the electrons? I'm pretty sure the electrons still release electromagnetic radiation, but how does the 'standing wave' model make sense for how the electrons do not fall into the nucleus of the atom? My second question at this point is, what are these 'standing waves'? I'm trying my best to think of these standing waves outside of its classical interpretation, but its getting kinda fuzzy in my mind. Are they mapping out the orbitals / probability clouds? (Which if I recall correctly, is described by the wave function as given by Schrodinger's equation.) Please do correct me if there are any discrepancies in what I've typed out so far. Thank you for any help given. [link] [comments]  |
| Can regenerative animals keep regrowing the same limbs over and over without any loss? Posted: 18 Aug 2018 02:52 AM PDT For example, salamanders can regrow limbs/tails. What if that same limb gets chopped off again or multiple times, will it regrow back again perfectly or are there diminishing returns each regrowth? [link] [comments]  |
| Posted: 18 Aug 2018 09:13 AM PDT For example: say a spaceship accelerates away from a stationary observer. What would the observer's "world-line" look like from the spaceship's perspective and what would the spacetime diagram look like? [link] [comments]  |
