In the universe we see that hydrogen (bound up energy) is found in a highly concentrated ordered state in some places and it's highly dispersed in most other places. There is a natural progression that makes all of the elements heavier than hydrogen so is there a return cycle to make hydrogen again? If not, how did hydrogen (bound up energy) get into a highly concentrated ordered state as we see it today? (You could appeal to another universe and it still will not answer the question of how energy got ordered or made for that matter.)

    $\begingroup$ Your title asks about energy, but the question itself asks about hydrogen. That's a bit confusing, so you should fix the title to better reflect your question. Or change the question body to match the title, if you are really asking about energy. $\endgroup$ – PM 2Ring Nov 5 '18 at 18:07

  • $\begingroup$ In supernovas, the last phase just before the forming of the black hole or the neutron star is, that the temperature goes over some ten billion Kelvins. On that temperature, even the $He_4$ nuclei break apart, and the collapsing stellar core is pure hidrogen for some seconds. $\endgroup$ – user259412 Nov 5 '18 at 23:54
  • $\begingroup$ A star that goes supernova is already in an ordered state. My question is how the star got to be in an ordered state in a vacuum where hydrogen disperses into a less ordered state. $\endgroup$ – Jungle Jargon Nov 6 '18 at 0:05

When you talk about highly concentrated ordered states of hydrogen, are you referring to stars and galaxies? If so, they are formed by gravity. There is not a “return cycle” that makes hydrogen from heavier elements.

  • $\begingroup$ Gravity assembles planets as well as stars and galaxies. So in that sense energy can order or organize itself. $\endgroup$ – G. Smith Nov 5 '18 at 23:41
  • $\begingroup$ There has to be considerable mass for there to be gravity. The first element to have been made is hydrogen which does not have much mass unless it is already compressed into a liquid or semisolid metallic state and there is no energy in a vacuum to do that. (There is no other matter around in the early universe for much gravity to exist.- I don't see where the gravity would come from to bring a gas together in a vacuum.) $\endgroup$ – Jungle Jargon Nov 5 '18 at 23:53

  • $\begingroup$ Any amount of mass will attract. Gravity doesn’t “start” when you get enough mass. Two H atoms attract, although it’s too small to actually measure. The observable universe has something like 10^80 nucleons. If they were originally perfectly evenly distributed, they wouldn’t clump. But they weren’t, because of quantum fluctuations, so they did start to clump. As soon as the density became a bit larger in some regions, gravity amplified those clumps and eventually produced galaxies. $\endgroup$ – G. Smith Nov 6 '18 at 0:11
