| When a rocket lifts off, is the entire weight borne by the nozzle assembly? Posted: 29 Mar 2021 02:38 PM PDT If so, what specific part of the nozzle(s) bear the weight? How big is this connection compared to the bell of the nozzle? And due to acceleration, do G-forces cause the weight to be greater than the rocket weighs at standstill? [link] [comments]  |
| Are there stars that orbit perpendicular to the galactic plane? Posted: 29 Mar 2021 08:25 AM PDT In spiral galaxies, there is commonly a 'galactic bulge' of light. As most of us know, stars usually orbit around the plane, but is it possible for a large number of stars to orbit at (at least close to) a 90 degree angle relative to this? If so, how would that formation process have occurred? Or am I overthinking it and the bulge is simply a result of the massive light output from the high density of stars? Edit: just to clarify, I know that there are irregular galaxies that are composed of stars in a 'cloud' of sorts, like the Magellanic Clouds. I am referring to conventional spiral galaxies for this post. Edit 2: by 'large number', I'm referring to a significant portion of the total number of stars. Maybe 0.1-1% of total stellar count or mass. Something along the lines of 0.1-10 million stars at least. [link] [comments]  |
| Why do these biotite crystals have blurred edges in thin section? Posted: 30 Mar 2021 06:59 AM PDT Hello! I'm fairly new to geology, so not completely confident. I'm studying this sample in thin section (I know I can't add photos) and the biotite is slightly different to the characteristics I know. It seems that in places the edges of the biotite crystals/ grain boundaries are blurred/ fading outwards, could anybody please tell me why this is? Is it to do with deformation or is it just simply the way it is? Also some of the darker brown crystals appear to have no cleavage (I know biotite has one), does anybody know if theres a reason for this please? Thanks so much! [link] [comments]  |

| Do new-borns have fear of falling ? Posted: 30 Mar 2021 04:18 AM PDT Ok . So here's a question : do young babies (who dont understand yet that falling can injure you) have a falling ? Like , if you keep you newborn on your sofa and then sit on the floor and call them , will they stop at the edge of the sofa to not fall or will they continue walking , unaware of the lack of solid surface in front of them ?

| Posted: 30 Mar 2021 10:45 AM PDT I'm referring to the Astra Zeneca Covid19 vaccine that Germany and France have said will not be given to under-60s, but this isn't specifically a Covid19 question. [link] [comments]  |
| Posted: 30 Mar 2021 10:12 AM PDT (Looking to expand on a recent post I saw): For instance, cases where patients have experienced peripheral nerve damage (numbness, throbbing, fizzing/buzzing, pain), where symptoms have persisted many months after infection. Obviously the vaccination doesn't contain the live virus, but if the initial nerve symptoms were a result of an irregular immune response to the antigen, what are the chances that the vaccination-provoked response could be similar (and potentially worsen the neuropathy)?

| Why isn't biomass carbon neutral? Posted: 30 Mar 2021 12:49 AM PDT Surely if all the carbon in the tree comes from the atmosphere, then it isn't actively adding new carbon in when burnt? I've seen arguments stating that it isn't carbon neutral because of transport, but similar arguments can be made of the production techniques and the vehicles used in servicing wind and solar farms. I ask because of this article [link] [comments]  |

| What happens if there's difference in mass with a matter/antimatter annihilation? Posted: 30 Mar 2021 07:16 AM PDT So this is a question I've had for a while but can't seem to find an answer for by googling it (maybe I'm just using the wrong terminology), but what happens if there's a mass imbalance between matter and antimatter during annihilation? For example, if a positron came into contact with an entire atom, the positron would only "destroy" one electron, so what would happen to the rest of the atom? Would the atom just change into a different isotope/element, or would the energy created by the electron-positron annihilation be enough to break the atom apart into its individual protons/neutrons/remaining electrons? Would the mass of the atom make a difference? [link] [comments]  |

| Posted: 29 Mar 2021 10:40 AM PDT I know this question is very specific, and I am sorry if it has been asked a million times before, but of all the threads explaining how the mRNA vaccines work, this seems to be the only question I couldn't find an answer to. I have seen people saying that the spike protein "sticks" to your cells. Does this mean your body thinks that cell is a viral one and destroys it, or just removes that protein and lets the cell carry on? Super quick, hopefully accurate context the best an engineer can give: The vaccine delivers mRNA to your cells. Your cells use that as instructions to create the same spike protein the virus uses. Your body uses that spike protein to create antibodies. The cell gets rid of the mRNA itself(?). [link] [comments]  |

| Vaccine side effects due to immune response, but no symptoms due to infection? Posted: 29 Mar 2021 08:11 AM PDT I get that the Covid vaccine, especially on the second dose, can cause side effects due to the body generating an immune response to the spike protein. However, why wouldn't you get this type of reaction during a subsequent real infection; instead the vaccine gives very good protection against symptoms. [link] [comments]  |
