| How dense are asteroid fields and would they pose a problem flying through? Posted: 30 Aug 2021 04:45 AM PDT I was watching StarWars episode V and was curious if asteroid fields were seriously that dense? Also am I right in assuming most of the asteroids should be moving in the same direction? [link] [comments]  |
| Why are anti-parasitics (ie hydroxychloroquine, remdesivir) tested as COVID-19 treatment? Posted: 30 Aug 2021 08:19 AM PDT Actual effectiveness and politicization aside, why are anti-parasitics being considered as treatment? Is there some mechanism that they have in common? Or are researches just throwing everything at it and seeing what sticks? [link] [comments]  |

| Why do surgeons use intermittent pneumatic compression devices even during short surgeries? Posted: 29 Aug 2021 09:03 PM PDT Sorry if this is the wrong subreddit. A couple years ago I had a surgery that only lasted about 1.5 hours, but my surgeons put an IPC machine (the leg squeezy thing that prevents blood clots) on my legs anyway. wouldn't it take more time to develop a blood clot than lying down for a few hours? Is it more of a liability thing? [link] [comments]  |
| Is it possible for the delta variant to only infect a vaccinated individual's nasal cavity? Posted: 29 Aug 2021 07:18 PM PDT I've been reading how a lot of vaccinated people are testing positive with typical sinus infection or cold symptoms. They have some congestion and sinus pressure, may lose their sense of smell, but that seems to be the extent of their symptoms. Many people seem to think it's just allergies. From some research, it seems like the vaccine promotes IgM antibodies, but IgA antibodies which reside in mucosal surfaces fade quickly. Is it possible that an individual could be infected where they get exposed to the delta variant, but because of IgM antibodies it stops in the nasal cavity, which is why the symptoms seem to be less severe in vaccinated folks? Would this also prevent long covid if the virus never can inflict damage to other organs? [link] [comments]  |
| Why EXACTLY are Category 5 hurricanes classified AT 157 mph? Why THAT number exactly? Posted: 29 Aug 2021 07:44 AM PDT So with Hurricane Ida impending, I was curious as to why the Saffir-Simpson Hurricane Wind Scale appoints hurricane category cutoffs like it does? I understand damage proportion and know the scale does not account for storm surge, flooding, or tornadoes. Thanks! [link] [comments]  |

| Why Do Hurricanes Speed Up When They're Over Land? Posted: 29 Aug 2021 07:39 AM PDT Title says it all. I'm a bit of a weather nerd and we're getting into peak hurricane season. I've always been curious about this. [link] [comments]  |

| Why was Cassini destroyed and Voyager not? Posted: 29 Aug 2021 12:32 PM PDT So I know the Voyagers are still controlled by NASA but after they run out of fuel and stop sending information, isn't it possible that they could hit a planet and contaminate it with bacteria from Earth? We don't know what exactly the spacecrafts could find there because that area is so unexplored, so what if there is a planet with a chance of supporting life? It's like the Cassini mission, where they sadly destroyed the spacecraft because they didn't want to risk a collision with Enceladus or Titan and contaminate it with Earth bacteria. But NASA won't destroy the Voyager spaceships, so isn't that risky? I know that technology wasn't as developed when they launched them as it is nowadays, but NASA took the mission not to affect other worlds and let them in their natural state. It has very low odds to happen but still, what if they crash in an Enceladus-like world and possibly contaminate it? That would basically break NASA's vow not to affect other planets and so. Would it have been better to end them like Cassini to avoid this possibility? Is it possible though? (ok that's a lot but these questions have been troubling me for quite long :)))) [link] [comments]  |
| Do hurricanes hit the east Atlantic? Posted: 29 Aug 2021 07:38 AM PDT We always hear about hurricanes in the Atlantic hitting the east coast of the US, Caribbean, etc. The west side of the Atlantic. But I can't remember ever hearing about them hitting the west coast of Africa or anything like that. Is that just US focusing on US and not talking more about the outside world, or do they really hit over there more rarely? And if so, why? [link] [comments]  |
| What material would break the loudest? Posted: 29 Aug 2021 02:12 AM PDT I was wondering, if loudness of breaking things is somehow connected to their hardness. In that case, a diamond rod (for example) would be unbeatable in terms of sound? [link] [comments]  |

| Can infinite ordinals include negatives? Posted: 29 Aug 2021 06:28 AM PDT So for example can one have the ordinal number omega - 1, which comes immediately before omega, or omega2 - omega, which would be somewhere between omegaarbitrarily large number and omega2? Or omegaomega + omega3 - omega*4 + 5? Or must Ordinals be strictly increasing? [link] [comments]  |
