| Can someone explain why Saturn has a hexagon at its uppermost pole? Posted: 28 Apr 2019 06:18 PM PDT I saw this image on Reddit and am completely dumbfounded. Thanks! [link] [comments]  |
| Why does the water exiting the nozzle of a water bottle rocket create waves? Posted: 28 Apr 2019 07:06 AM PDT So my classmate and I created a water bottle rocket and have decided to record it with a 60fps camera zoomed to the rocket itself. From what we can see in this frame, there seems to be some sort of oscillation in the water being pushed out of the nozzle. Why does this occur? Edit 1: Will be uploading launch video in a few hours. Edit 2: Video [link] [comments]  |
| What actually kills us from lack of sleep? Posted: 29 Apr 2019 12:12 AM PDT Sleep deprivation for a long enough period of time is capable of killing people. We know sleep is necessary to live, but do we know why that's the case? What actually causes you to die if you're so severely sleep deprived that you reach that point? [link] [comments]  |

| Posted: 28 Apr 2019 08:58 PM PDT How likely are we to start simulating the other senses? It seems like itd be exceedingly complex, but so does television until you realize its just 3 colors and that our speakers are just a vibrating diapgram. But things like smell and taste arent exactly on the same level. Id assume that smell and taste are just uniqe things about life and not fundamental concepts of reality. But im usually wrong about the difficulty of things. [link] [comments]  |

| Posted: 28 Apr 2019 05:34 PM PDT I have always assumed that some SRP receptors make it to the Golgi/plasma membrane during forward transport. If they are degraded, how are they selectively chosen? Is this assumption wrong? Or is this just a matter of proximity? Thanks! [link] [comments]  |
| Posted: 28 Apr 2019 10:53 AM PDT 1) is it possible for there to be, somewhere in the universe, planets made of antiparticles? I know that theoretically half matter half antimatter was created, but since our solar system exists, could there are ossicle be an "inverse" with antimatter? 2) I recently read an article about neutrinos which said that neutrinos might be their own anti particles. If (hypothetically) that was the case, could you create energy by only making neutrinos and making them collide? 3) what are the "unwanted emissions" when matter and anti matter collide ( the equivalent of radiation for nuclear fusion, CO2 for fossil fuels, etc...)? 4) I saw a video about strange quarks and strange matter and how( in theory) everything it comes in contact with also turns to strange matter. How does that process work? Sorry that I have so many questions! [link] [comments]  |

| What's the theoretical size limit of a star? Posted: 28 Apr 2019 04:35 PM PDT So I know that our sun is a third generation star. And that stars used to be more massive. So if I went back let's say 11 billion years ago what would the average mass of a star be? And what would be the behemoths of that generation? [link] [comments]  |

| How do we distinguish gravity waves? Posted: 28 Apr 2019 08:29 AM PDT For instances how do we distinguish between them from a collision of neutron stars or a collision of black holes? [link] [comments]  |
| What is the chemical composition of pre-ejaculate? Posted: 28 Apr 2019 07:20 AM PDT There's a ton of research out there about whether or not pre-ejaculate from the Cowper's Gland contains sperm, but I can't find a single article (scholarly or otherwise) that actually breaks down the chemical composition of pre-cum. Searching in this sub, I see this question has been asked only once 10 months ago and didn't get a response. Can someone please tell me or link me to an article that breaks down the composition? Thank you. [link] [comments]  |
| Did Earth increase the speed of its revolution at any point in its history? Posted: 28 Apr 2019 07:16 AM PDT Someone recently told me that the meteor that caused the mass extinction and the gulf gulf of Mexico sped up the revolution of the earth causing days to be shorter. He also claimed that impact is what caused the formation of the moon as we see it today. Is any of this true or even plausible? [link] [comments]  |
| Before the modern world, what caused the Earth's temperature to regularly vacillate 15 degrees (C)? Posted: 28 Apr 2019 07:47 AM PDT I'm speaking to this graph here: https://i.imgur.com/HpVkWti.png You can see that the earth is rather steadily moving between periods of warm and cold. What were the factors that contributed to the climate shifts that caused these dramatic changes in both directions at what looks like regular intervals? [link] [comments]  |
