- If two objects collide on Earth, their kinetic energy is converted to other forms such as light and sound. But in space, it can't be converted into sound energy, so what would it get converted into? And would it be more destructive for the objects in question? Or am I completely misguided?

| Why does the CMB tells us spacetime is flat ? Posted: 02 Jul 2019 04:30 AM PDT Hey there. In the PBS Space Time series, in the episode about the CMB, they explained the "dots" in the CMB are approx 1° in width, and this facts is related to having a flat spacetime. Why ? Since spacetime works like a "filter" on the CMB we see, aren't there other CMB/spacetime curvature "combinaison" making us see the same result ? If im not clear : if a flat spacetime gives us the CMB we see today, isn't it possible the CMB is totally different and spacetime curved in a such way we see the CMB like we do ? Maybe I dont get something and the answer is obvious, but I had that in my head for a long time. Thanks ! [link] [comments]  |
| Does the Higgs Boson have more mass than the protons that were collided to create it? Posted: 02 Jul 2019 04:55 AM PDT My search attempts seem to suggest that it does have more mass than an individual proton at least. But I'm assuming that's at rest (if it matters here)? Does this mean that it's a demonstration of the creation of mass? Is this "creation of mass" seen elsewhere in particle physics? I apologize if this is all so confused as to be unanswerable.

| How exactly do Lagrange-4 and Lagrange-5 work? Posted: 01 Jul 2019 03:50 PM PDT I feel like I understand L-1 through L-3 pretty well. L-1 is just where gravitational "forces" subtract perfectly to slow down orbits to geosynchronous, L-2 is where they add perfectly to speed up orbits to geosynchronous, and L-3 is on the opposite side of the sun as L-2 but has the same effect. However, no matter how many explanations I hear or how many diagrams I see, I still can't figure out what is so special about +/-60 degrees in the orbit, or why these are actually stable instead of metastable.

| How do video game controllers compare to each other in terms of hand health? Posted: 02 Jul 2019 01:59 AM PDT Since hand and wrist problems are becoming a problem in gaming, I've become interested in the controllers we use. In articles covering the topic I normally only see exercises being mentioned as a treatment, while my intuition tells me switching from gamepad to keyboard would help significantly when possible. The only example I know of this being brought up is with hax$ and smash brothers melee. Here's a 6 minute video on the story if interested: https://youtu.be/tCOISFOWswc Question: How do game controllers compare to each other in terms of hand health in high apm games? keyboard vs. keyboard + mouse vs. gamepad?

| What makes someone develop one eating disorder over another? Posted: 01 Jul 2019 09:00 PM PDT For example, what causes someone to develop anorexia over bulimia or binge eating disorder? They all share similar risk factors of depression, anxiety etc, but wondered if anyone could shine more light on the causes of developing one ED specifically. [link] [comments]  |
| Why do soda bubbles tend to go to the side of their container? Posted: 02 Jul 2019 04:10 AM PDT I noticed that when bubbles form in the soda they tend to move from the center to the sides and then stick there, when I asked my physics teacher he vaguely answered it was due to water tension, so I wanted an proper answer regarding why this movement happens and why do they stick on the walls.

| Are the Southern Alps growing? Posted: 01 Jul 2019 03:59 PM PDT I know they're being pushed up by the Australian and Pacific plates. At the same time they're being eroded: Aoraki lost 10m of rock from the summit in 1991. Are these processes in equilibrium or is one tending to dominate? Is there a general rule about whether mountain ranges are in equilibrium or is a case-by-case question? [link] [comments]  |
| Posted: 02 Jul 2019 12:25 AM PDT Basically title. I'm asking if someone knows if this could be true, or has any research. My Google-Fu is weak, and I request a master's skill. The reason I started thinking this was due to this article. "After a cool May, it finally warmed up in June in Germany. A lot. Last Wednesday, the thermometer near Guben in the northern German state of Brandenburg reached 38.6 degrees Celsius (100 degrees Fahrenheit). That marked the first time since measurements began in 1881 that a temperature that high was reached in Germany in June." I was basically wondering why the temperature record in Germany hadn't been beaten until now, 140 years later. Sure, the globe is heating (I'm a firm believer in climate change/AGW), but this little fact seems weird to me. The reasoning would be that, yes, high-pressure systems obviously still occur, but something might've changed in the climate to make these extreme high-pressure bubbles appear. Little help?

| Posted: 01 Jul 2019 11:57 PM PDT I, like many others, was fascinated with the Chernobyl mini-series. The final episode did an amazing job of explaining step by step what went wrong and why. I loved the visualisation of the red and blue cards. I understand that in Fukushima Daiichi, the plant was flooded and therefore generators responsible for pumps / cooling down of the reactor failed, therefore the core started to overheat (So in Chernobyl the mini-series style, the Red cards started increasing and there were no (?) blue cards to balance it). But the reactors were shut down (is this with a kill switch, similar to AZ-5? or is that an RBMK reactor-only function?), so why did the meltdown occur? Is Xenon poisoning also an actor here? Why did the heat went up and ultimately, what happened? Edit: I went with the Chemistry flair as I couldn't find any "nuclear" option. I hope that's allright. Please don't kill me.

| Falling into a black hole, looking outward; what do you see? Posted: 01 Jul 2019 11:18 PM PDT I've wondered about this for a while. Set aside the physical effects on a human body and assume the black hole has no accretion disc or immediate source of light to obscure an outward view. As you fall into a black hole, with time dilation being so pronounced, would you see the fate of the universe play out as you reached the singularity? My understanding is that you'd still be able to see the external light entering the event horizon that you are inside of. Would you see heat death or Big Crunch or some other cosmic ending? Would it happen in a reasonably perceptible time or in a flash? Am I missing something? I appreciate this is an unknown realm. I just wanna hear people's thoughts. [link] [comments]  |
| What was the daily temperature during the “little ice age”? Posted: 01 Jul 2019 06:52 PM PDT During the little ice age, the climate was from 0.5 to 2.0 C colder than today. What does that mean in daily high and low temps for summer and winter? This has been surprisingly hard to find. [link] [comments]  |

| Posted: 01 Jul 2019 11:28 AM PDT Hello. I was trying to find an answer to this question and found this article: http://www.atomicarchive.com/Effects/effects1.shtml . It starts with
I thought that gave me an answer, but it later talks about "equivalent megatons (EMT)" which got me all confused. An other way to phrase my question would be: [link] [comments]  |

| So, inflammation is a common reaction to injury. Does that mean inflammation is a good thing? Posted: 01 Jul 2019 06:57 AM PDT (Edited to be clear that this is a general science question and isn't a request for personal medical advice...) Patients experiencing pain are often given anti-inflammatories, but now I'm wondering: is it really a good idea to always suppress inflammation when it appears? Are we suppressing some healing process when we do so? [link] [comments]  |
