| Is there any intuitive way to visualize the symmetries of the standard model? Posted: 18 Dec 2019 12:09 PM PST U(1), SO(2), SU(3), SO(3,1), i keep seeing these again and again when trying to learn about physics, but I have no idea of how to picture these visually as anything other than a bunch of matricies that I don't understand because I don't have a way to picture them. is there any sort of intuitive way to understand then?

| How is it that shockwaves can occur in space? Posted: 18 Dec 2019 01:13 PM PST My understanding is that shockwaves need an atmosphere to "shock" or distort. Referring to the supernova that the Hubble telescope caught that is circling on Reddit. [link] [comments]  |
| Can a person with the flu vaccine still spread the flu? Posted: 18 Dec 2019 10:37 AM PST I was just wondering if you are vaccinated and you are exposed to one of the strains of virus the vaccine covers, and your body fights it off, is it possible in the period of time that your body is fighting it off for you to spread the virus to others? So I guess I'm wondering at what point you become contagious? i know viruses hijack your cells and eventually lyse your cells once they have used it's machinery to replicate, is it at this point at which you become contagious? Once the viruses reach a certain "dosage" from replication within your body? [link] [comments]  |
| Why isn’t RAM replacing the hard drive at this point? Posted: 18 Dec 2019 06:21 PM PST It seems like RAM has be increasing with more space and at a quicker rate. It's always been like that. But it seems like we are getting to a point where RAM will be capable of handling average peoples storage needs. Then grow after that. My question is, what is stopping us from creating a RAM only machine and having it serve our needs without an SSD. [link] [comments]  |

| Why is the ocean level equal to continental height? Posted: 18 Dec 2019 02:09 PM PST If the ocean level were 1km lower, we would be on a plateau 500 meters high with steep edges. So is it just a coincidence oceans have exactly that height or is there some process behind that? [link] [comments]  |
| What's stopping our sun from crashing into another Sun? Posted: 18 Dec 2019 08:57 PM PST Hey, so I just had an edible, so sorry if this question seems obtuse. I understand that our sun is constantly moving across the galaxy, just as our planet is constantly moving around the Sun. Throughout all this movement, is there any scenario where our Sun crashes into another neighboring Sun sometime in the near or distant future? If not, what's stopping that from happening?

| Why doesn't Deuterium spontaneously form from most Hydrogen neutron collisions? Posted: 18 Dec 2019 10:05 AM PST As I understand it, in nuclear rectors, Uranium releases neutrons which collide with water molecules to slow down. Since there are a bunch of neutrons bouncing around, presumably some are colliding with some hydrogens in H2O. The binding energy of Deuterium is ~2MeV, and neutrons start out at around ~2MeV but slow down to much less than that, so it doesn't make sense to me that the neutrons are going too fast to make the reaction favorable. There shouldn't be any repulsive force when the neutron gets close to a proton and they should actually attract each other when they are close enough for the strong force to be in effect. So why don't these collisions result in deuterium production? [link] [comments]  |
| Posted: 18 Dec 2019 11:01 AM PST In oxidative phosphorylation (OXPHOS), I get how complexes I-IV in the mitochondria play a major role in respiration via their various redox reactions, coupled to the passing of electrons, and pumping of protons into the intermembrane space. My questions is what exactly is the "phosphorylation" part of the term OXPHOS referring too? Is it referring to Complex IV where oxygen gets turned into water? Or the coupling of complexes I-IV? Thanks for the help. [link] [comments]  |

| Posted: 18 Dec 2019 08:38 AM PST (Note that this is tagged as biology since I'm not sure what else to tag it as, but biology seemed the closest) I've always seen that paper, glass, plastic, etc., is supposed to be recycled, and I get how most things are: they get melted and reformed into something with a different shape and purpose. but paper? that stuff can't melt. how does it get recycled?

| Was there a specific criteria for constellations to be officially recognized by the IAU? Posted: 18 Dec 2019 06:34 AM PST There are some really interesting constellations (e.g. Quadrans Muralis) that aren't included in IAU's 88 official constellations. I'm wondering if there was any criteria that had to be met for a constellation to be recognized among those 88. [link] [comments]  |
| Posted: 18 Dec 2019 11:41 AM PST I got confused while trying to think if I remember flat pictures only or actually full stereoscopic 3D objects. Did I spend too much time in front of a 2D screen? [link] [comments]  |
