| Can there be particle accelerators for chargeless particles? Posted: 11 Jul 2017 05:16 AM PDT Can particle accelerators be built, in theory, to accelerate particles on the basis of color or spin, instead of their electric charge, if a particle has no components that carry charge? E.g. would it be possible to draw gluons out of a G/Q plasma and move them around in one way or another by the means of fields? [link] [comments]  |

| Why isn't there muscle cancer? Posted: 10 Jul 2017 08:37 AM PDT We hear all the time about brain cancer, skin cancer, lung cancer, breast cancer, stomach cancer, etc., but why do we never hear of malignant, cancerous tumors from developing in muscle tissue? Is there something unique about the makeup of muscle fibers that prevents abnormal growth? EDIT: I'm specifically referring to skeletal muscle and why rhabdomyosarcoma (RMS) is rarer than other types of cancer. (Thanks /u/seanbrockest) [link] [comments]  |
| How are electronics cooled in space? Posted: 11 Jul 2017 12:34 AM PDT Hi guys, I just saw some youtube videos of some fancy tech in space. During the video I started to wonder how you keep things in space cool enough to operate properly. If i think of my pc here on earth, heat is transmitted from my CPU to the air. In space however, there is no air. So how do people keep electronics in space from dying from overheating? My first thought was, maybe they use some sort of water cooling tech, but that still wouldn't be enough for CPUs to be cooled for long periods of time, since the water still would rise in temperature and maybe even burst the pipes when getting too hot. Does anyone know how electronics are kept cool in space? Thank you :) [link] [comments]  |
| What are these straight line formations in the middle of Australia and what caused them? Posted: 11 Jul 2017 06:04 AM PDT This is the phenomenon I'm referring to. The very weird straight drainage patterns it results in can clearly be seen on the beautiful map of the continent's river basins seen on this reddit post, which led me to ask the question. Is this natural? How did it occur? Why is it unique to that area in Australia? Does a similar phenomenon occur elsewhere on Earth? [link] [comments]  |
| What actually happens when we "get used to something"? Posted: 10 Jul 2017 08:29 PM PDT Say after you spend some time at the landfill, you stop smelling the foul odor, or you live next to a busy street and stop hearing the traffic, or you live in an area with higher metal contents in the water and stop tasting it. What is actually occurring when we stop smelling/hearing/tasting a frequent sensation? [link] [comments]  |

| Posted: 10 Jul 2017 07:43 PM PDT Any object entering a body of water will cause displacement thus making the water rise, but an aircraft carrier compared with the world oceans? I can't imagine the number being remotely significant [link] [comments]  |

| What is the difference between absorbing and capturing a neutron with regards to the Tritium bonus? Posted: 10 Jul 2017 07:41 PM PDT I'm looking at the Tritium Bonus of the Castle Bravo detonation. The scientists only enriched 40% of the lithium to 6Li, thinking that the 7Li was inert. It was thought that the 6Li would absorb a neutron from the 239Pu and emit an alpha particle and 3H, the latter fusing with the 2H, whereas the 7Li would absorb a neutron to become 8Li and decay to 8Be and eventually 2 alpha particles. But what happened was the 7Li captured the high energy neutron instead of absorbing it and immediately decayed into an alpha particle, a 3H nucleus, and another neutron, so a lot more of the 238U fissioned and the yield was much higher than expected causing radiation and fallout problems. I'm not understanding what the difference of the 7Li absorbing a neutron to decay through 8Be and capturing a neutron to produce more 3H nucleus and another N. this wasn't something that was known at the time I take it.

| What minerals were present in Earth's crust when tectonics began? Posted: 10 Jul 2017 06:22 PM PDT I'm wondering what minerals would have been found in the earth's crust when plate tectonics began. A good reference to read would be fantastic. I know that many of the minerals we have today formed over time due to interactions with water, chemistry, and life. Curious what was around back then.

| Posted: 10 Jul 2017 08:57 AM PDT Lithium carbonate is an antidepresant, I was wondering why there was no LiCl for medical use and found that it was toxic. Why is that? [link] [comments]  |
| Does the time at which we sleep affect or bodies? Posted: 10 Jul 2017 08:17 AM PDT Does the time at which we sleep affect our brain and body? its common knowledge that you need around 8 hours of sleep but i was wondering if WHEN you slept mattered. say i sleep every single day at 2 am and get atleast 8 hours of sleep as compared to sleeping at lets say 10 pm and also getting atleast 8 hours of sleep. would there be a difference as to how our brains and bodies develop? ive looked for awhile and couldnt really find much. most people and articles say sleeping late is bad but what if you do it regularly? would your body even consider it "late"?

| Posted: 10 Jul 2017 04:45 PM PDT Since it is travelling in a vacuum, it will travel forever until it hits something, right? What are the odds it hits something vs hit nothing? What are the odds that the thing that it hits a star vs a planet vs a black hole, or whatever else? [link] [comments]  |

| How long did NASA truly expect the Mars Rovers to function? Posted: 10 Jul 2017 04:09 PM PDT NASA said they would survive 90 days. Spirt operated for 2269 days. It's always best to over deliver. Are there true predictions and likely ways they would fail? [link] [comments]  |
| Can a binary star system have a small (Jupiter size) star orbiting a larger (Sol size) star? Posted: 10 Jul 2017 06:52 AM PDT In Arthur C. Clarke turned Jupiter into a star (in his book "2010") in order to provide warmth/light to one of its moons. Can a solar system like this actually form? That is: one small star very much in orbit around a larger star similar to our own. [link] [comments]  |
| Is the process that created oil and gas continuing today? Posted: 10 Jul 2017 08:11 AM PDT Or was that process only present during a particular time of our planet's development? [link] [comments]  |
| Why don't they make spacesuit helmets that fit tightly on your face? Posted: 10 Jul 2017 05:53 PM PDT Kinda like mass effect... or even Iron Man. The neck could be made out of fabric just like the whole suit, but the face plate would contain the metal ring and seal, which means that the neck would be flexible. [link] [comments]  |
| What would the perspective an observer going near-light speed look like? Posted: 10 Jul 2017 01:23 PM PDT I understand that, according to Einstein's Relativity, the closer one gets to the speed of light, the slower time moves for them (relative to our perspective here on Earth, for example). If we were to theoretically look at them, we would see them move extremely slowly because they experience time at a much different rate than us. But let's say we were the travelers. What would we see if we were theoretically able to stably observe the world moving past us? If we were able to observe Earth? Would it look like Earth, and everything on it, was moving in fast motion? [link] [comments]  |
