Quark (2/13)



  1. That (and swansont's answer) answers most of my questions. Though I was wondering if you know the answer to my last question too: Is this how all neutrons were originally formed?
  2. Well, but those are atoms, right? Doesn't that mean that they simply release a neutron that was already present in their atomic structure?
  3. Let me preface this by saying I'm not a physicist, or physics student. Now that we have that out of the way, I've been playing a game called Elite Dangerous and seeing a neutron star there reminded me that while I've looked up plenty on black holes, I'd never really looked into neutron stars very much. So I was looking up the composition of a neutron star, etc. and I read (on this website http://science.nationalgeographic.com/science/space/solar-system/neutron-stars/) thata neutron star's birth involves " A neutron star's almost incomprehensible density causes protons and electrons to combine into neutrons." Now, is this correct? How do protons and electrons combine into neutrons? Why don't they normally bind into neutrons while inside of an atom together? Just lack of pressure condensing them? And finally, is this how all neutrons ever are formed?
  4. I think that answers my question pretty fully now, thanks. Though a side question: Is there any sort of graph which shows how the rate would change depending on those last factors you mentioned?
  5. It was not in fact the original question. I was personally looking for more of an answer in femtoseconds or something. You know, the time it takes for two hydrogen atoms to fuse together from the moment it becomes possible for them to do so. Or alternatively what the timetable would be for 1 gram of hydrogen to become fully fused. Alternatively the equivalent of "half-life" would also be a fine answer (since it may in fact be the case that the rate slows down).
  6. This may be kind of an odd question, but provided that two hydrogen atoms are in a position where they are about to fuse, how long does this process actually take? As an extra question, how long would it take to fuse every atom in 1 gram of hydrogen, assuming you had conditions that allowed for this to happen?
  7. So what about previous species of human then? Strays kind of away from my central question, but you have made me curious.
  8. That last thing is something I was wondering about. This seems fairly complex for the earliest human groups. I would've expected something more like the system of other genetically close species of ape.
  9. What do these caste systems generally entail? And does that mean there's a leader caste who makes decisions for the group? So you're saying that culturally it was sort of like a "high school" where there weren't so much rules among the individuals participating in the group or a larger governing structure but rather cliques of people where one or multiple may have a "pecking order" amongst themselves and that interact based on reputation, rumour and whatnot? And I mean the students of a high school, not taking into account the organized structures of the teachers, etc.
  10. Any links to any of these maps? Well, but there must be a currently more-or-less accepted migration pattern, no?
  11. I was wondering about what the organization of "groups" of humans was in prehistoric times. Here, of course, I'm talking about before we started using agriculture and before we started settling in one place. What was the typical size of a group of humans? Why was it this size? How was it lead? How were the jobs divided? What was the hierarchy? How was the hierarchy maintained or changed? How was it organized? All of that good stuff. So, any thoughts? Simply links to for example documentaries about this are also appreciated.
  12. Is there anyone out there who has a map of the world (as it was thousands of years ago) where the various waves of human migrations are marked with arrows with the arrows also having dates? I'm talking here of course about the migrations that occured while we were still hunter-gatherers. If possible it would also be very interesting if someone could tell me what the pain push and pull factors for humans were at that time.
