| ELI8 for Rain vs Bubbles please? Posted: 28 May 2020 07:02 AM PDT My 8yo recently discovered that bubbles do not pop in the rain, even rain brought in by a tropical storm (honestly, I was surprised too, I thought the torrential downpour would pop them). I tried to look up the science behind it and couldn't find an explanation that I understood well enough to explain it on the 8yo's level. Can any one help us out? We're still curious and ridiculously gleeful that you can blow bubbles in a tropical storm and they will just happily beebop around in the wind and rain. TIA! [link] [comments]  |
| Could we launch a space shuttle using a railgun? Posted: 28 May 2020 01:06 AM PDT Could we make an electric SSTO using a railgun and ion engines? although we haven't reached escape velocity with a railgun, could we still do it if we just use enough energy? happy to answer any questions [link] [comments]  |
| Why are rocket launch windows so narrow/sparse? Posted: 27 May 2020 01:40 PM PDT The falcon 9 launch today was scrubbed due to weather, the commentators seemed to think the weather would have cleared 10 mins after T-0, I get that they need to arrive on time to intercept ISS at the right moment, but why not just wait 90 mins for ISS to come back around?

| Do we have any idea what came before our solar system? Posted: 28 May 2020 01:59 AM PDT My understanding is that around 4.5 billion years ago our star formed out of a cloud of gas and dust, and that our planet formed out of what was left. But what was that gas and dust? Where did it come from? I am assuming that it did not come directly from the Big Bang, because there was too much complex stuff in there. So did we form from the remenents of a supernova or a single dead old star? Did we form out of many old stars or did many new stars form out of a single old star? If the old stars had run out of fuel and finally died, where did the new fuel come from to ignite new stars? [link] [comments]  |
| Why is prostate cancer associated with bone loss? Posted: 28 May 2020 07:04 AM PDT Prostate cancer likes to eat your bones - is it because of metastasis, is it treatment-induced and what is the mechanism? [link] [comments]  |
| Is there a relationship between bullet density/weight and speed needed in order to penetrate a body? Posted: 28 May 2020 03:06 AM PDT Assuming you were able to shoot something other than a bullet, like earplugs made of foam/gym, or a vitamin pill, or a rubber eraser without it breaking up, how would you calculate the speed needed for it to "kill" a human, or simply put penetrate his body? I remember someone telling me if you drop a dollar from the Empire State Building you could kill someone due to the speed it reaches falling down, but I assume that's also because it keeps accelerating while a bullet doesn't? (Correct me if I'm wrong) [link] [comments]  |
| Posted: 28 May 2020 06:25 AM PDT I've done my fair share of brake jobs and I've always wondered how OEM rotors are able to take far more abuse than their aftermarket counterparts. [link] [comments]  |
| Posted: 27 May 2020 05:25 PM PDT I know that documents/primary sources are an essential resource in regards to etymology - but my studies only required a few linguistics courses. So my knowledge on etymology itself is lacking. How exactly do etymologists determine when a word transferred from one language, to another language that does not share a common ancestry? For example, words in modern Japanese that came from the English language, or another indo-european language. I am sure there are countless examples with many languages - but most importantly, what sort of things are taken as solid proof of the transfer occurring? Is there much debate among etymologists about how those words got their origins? Also, are there examples of words that came to be, similar to the concept of convergent evolution? Edit: added a word for clarity. [link] [comments]  |

| What would happen to plants and animals if the magnetosphere was weakened? Posted: 27 May 2020 07:49 PM PDT I know that exposure to solar radiation, in space for example, can cause blindness or genetic mutations. I'm wondering how an increase in solar radiation would effect flora, fauna, and the climate. [link] [comments]  |
| What do we know about Covid-19 and mutation rate? Posted: 27 May 2020 12:20 PM PDT I haven't seen this asked, but if it was I apologize for missing it. I have several related questions I'm hoping y'all can help with. To my knowledge, viruses can mutate at will. Are there concerns about Covid-19 mutating? Do we know the rate at which that virus is likely to mutate? If the virus mutates, is it possible for it to become more severe/lethal? How would scientists know if it did mutate? [link] [comments]  |
| How long does magnetic reconnection take? Posted: 27 May 2020 08:33 PM PDT How long does the sun's plasma take to break apart its field and reconnect them? I've tried searching but to no avail. One article suggests it is a "lengthy process", but doesn't elaborate. [link] [comments]  |

| What is the smallest thing an ant can see? Posted: 27 May 2020 02:36 PM PDT As most of the cells are impossible to see to human eye, would it be that hard for smaller and smaller animals to see it? [link] [comments]  |
