| Why is the dark matter halo spherical? Posted: 23 Sep 2021 03:54 AM PDT Dilettante scientist here, so be gentle. As I understand it, galaxies are disc shaped due to the conservation of angular momentum, but the all the data I've seen about dark matter says that it is a roughly spherical distribution around the galaxy. Are there any theories as to why this is? Or is this evidence that dark matter doesn't even interact with itself? [link] [comments]  |

| Do viruses eventually reach some stable, optimal variant? Posted: 22 Sep 2021 11:17 AM PDT As a forewarning, I have a very limited understanding of biology and even less of virology, so this may be a very uniformed question. Viruses have their genetic information encoded into RNA, as I understand it. RNA is composed of several combinations of bases (ACUG), and these combinations functionally act as the viruses' code. Computers store information as bits, and there are a finite number of numbers that can be stored using any finite number of bits. My thinking is, since there are only so many combinations of A, C, U, and G in a strand of RNA with finite length, there are only so many virus variants possible. Eventually, selective pressures will force the disease to adopt some optimal configuration, such that any deviation from that variant creates a weaker virus. At this point would it be possible to create a vaccine that targets this specific variant, therein effectively nullifying the disease since any other variant would be unable to get past the vaccine that protects against the best virus?

| When an unstable isotope decays are the decay products always more stable than the original isotope? Posted: 22 Sep 2021 08:05 PM PDT If so, what is it about the weak interaction that makes such a decay path favourable? [link] [comments]  |
| Why don't we feel air pressure? Posted: 22 Sep 2021 02:20 PM PDT The standard explanation I've seen is that this is due to the air on all sides of us pushing equally, but that's not always the case. If I place my hand flat on a table, for example, there's no air under my hand to balance the pressure pressing down from the atmosphere. Even apart from that aspect, I would still expect to experience the pressure even if it's balanced. I understand that our bodies don't collapse (or at least squish a bit) because they're basically incompressible (cavities excepted), but I would still expect to feel it. According to Wikipedia the air pressure at sea level is around 1kg/cm2, which is a lot, but I can pinch my arm with far less pressure than that and still feel it clearly. It's been a few years now, but I've also dived to a depth of around 12m where the pressure is significantly greater, and I don't recall a feeling of e.g. my legs being squeezed on all sides.

| Did terrestrial flora exist before aquatic fauna moved out of the ocean? Posted: 22 Sep 2021 05:06 PM PDT At some point animals moved out of the ocean onto the land, before this happened was there a period when the land was covered in plants without any animals (or insects?) to eat them? Or did it happen simultaneously? [link] [comments]  |
| What was the classification of the sunspot that caused the Carrington Event? Posted: 22 Sep 2021 08:59 AM PDT I can't seem to find an answer from Googling, I'm not talking if it was an A/B/C/M/X flare, I know it was likely an X42. I'm looking for more of the sunspot composition (beta-delta-gamma, etc.) That produced the flare. I've tried classifying it myself, but my knowledge is limited in comparison to the Space-Earth Sci nerds/professionals. [link] [comments]  |
| Why is most DNA double stranded?? Posted: 22 Sep 2021 03:55 AM PDT There are single stranded viruses, as well as something called DNA triple helix,, however most organisms have a double helix What are the possible reasons for this??? [link] [comments]  |
| Why does some metal bend, while other metal shatters? Posted: 21 Sep 2021 09:39 PM PDT I watched a video of an industrial machine shredding engine parts, and noticed that the metal from the engine appeared to shatter instead of bend. Why is this? [link] [comments]  |
| What will happen with dead body in space over time? Posted: 21 Sep 2021 02:42 PM PDT Hi! Let's imagine a human in space with no spacesuit. Of course he is dead. But what happens then? Will his body rot and decompose? Or is he just gonna float in space with no changes forever? Btw sorry for my English :) It's my second language [link] [comments]  |
