| Posted: 27 Aug 2016 02:34 PM PDT So we can create all our visible colors by combining (additive or subtractive) a base set of three colors. However, what differenciates these colors is their wavelength which then again lies between the two points of red and blue (or let it be two points with an even shorter/longer wavelength). So why do we need three colors rather than two? And why then exactly three and not four or more? [link] [comments]  |
| Can an element's properties be predicted from the structure of its atom? Posted: 27 Aug 2016 09:44 PM PDT I.e., imagine there was no gold on Earth and humans had never encountered the stuff before. Would we be able to guess that "Unknown Element 79" would be yellow in color, very dense, and melt at 1947.52 °F based on the fact that it had 79 electrons, 79 protons, etc? [link] [comments]  |

| Are solar panels in space an efficient source of energy? Posted: 27 Aug 2016 02:24 PM PDT How would the energy be transmitted to the surface? In focused beams? [link] [comments]  |

| What affects the rate of growth of cancer? Posted: 27 Aug 2016 03:05 PM PDT I know that cancer is an broad term, but I was reading the story of Paul Kalanithi who had his cancer spread incredibly quickly, versus other cancers that are less aggressive. What exactly makes the rate of growth (of the same type of cancer) different? [link] [comments]  |
| How would galactic internet work? Posted: 27 Aug 2016 10:14 AM PDT Nothing can beat the speed of light, and we all know that, at least with our current technology. However, since we are eventually going to conquer another planet someday, we would want to figure out how to access the internet from a nearby star system. Let's say we conquer Proxima b - the closest planet that "supports" life, if we want the internet there, we'd have to start from scratch. If we wanted other websites from Earth, we'd have to wait 4.2 years, maybe even longer if the speed is slow. How would we turn this 4.2 years into seconds? [link] [comments]  |
| Could Dark Matter form "Dark Black Holes?" Posted: 27 Aug 2016 04:57 PM PDT It was an idea that occurred to me today after reading about Dragonfly 44. Could Dark Matter form a Dark Black Hole? If so, and the hole followed the same general laws as normal black holes, would that mean they would release a format of Energy as they evaporate? (Do they evaporate?) Sorry, this question got me thinking about a lot of different questions regarding Dark Matter. [link] [comments]  |
| Black holes. Could we see an event horizon's silhouette against a bright background? Posted: 27 Aug 2016 12:08 PM PDT From the perspective of earth. A black hole is positioned in front of a star. do we see a dimming of the star and possibly even the black disk of the event horizon silhouetted against the star? Or do we see a distortion/flipped image of the star due to gravitational lensing? [link] [comments]  |

| Posted: 27 Aug 2016 06:37 PM PDT I've heard some people say it's the same as the speed of light, but one of my friends says it is instantaneous. He says we could communicate across the universe using gravity kinda like in Interstellar. [link] [comments]  |
| Can d Electrons Ever be Valence? Posted: 27 Aug 2016 01:06 PM PDT So I know the traditional view is that elements want to get a complete octet and since the d subshell is considered n-1 when [back]filling, we usually don't consider it valence. What about if we had an element with a full s and d subshell (lets say Zn), which then lost 2+ electrons? The first electrons to be removed would be the 4s electrons by convention, meaning the 4n shell is now empty. How do we consider this new orientation, as 4s0 or 3s2,3p6,3d10? Thanks in advance for the help! [link] [comments]  |
