  • i like the liquid explaination and it makes sense,,, some thing my obtain a critical mass in order for it to be formed sphericaly,, this would be related to compression, pressure and finaly heat,

  • So many questions.. Why..

    Was there a Big Bang...

    Who or what created the Big Bang..

    Who or What created the space where the Big Bang occured....

    And so on ... Why do we wanna know the impossible?

  • @YEyup

    For the same reason that you want to know, why we wanna know the impossible.

  • i dont think the big bang is true

  • Why?

  • i belive that it the universe expands and then gravity make all matter come back into one peace then it expand then it all comes back to one peace like a never ending thing but, how the matter got in are universe was by a black hole in another universe the black hole made a opening in space were matter came in to are universe but i still dont know how all the universe started or how gravity started so i still belive in god , i have a spelling disability icant reallybut whatamthinking in words

  • i just subbed, as i recently found your vids randomally, and i found the analogy i guess... that you used to explain spherical objects very compelling and a good way to approach this question, i think i may adopt it myself :)

  • thanks for the great video response.

    i appreciate the time you spent on making it and the interesting information.

    ill pm you later.

  • Hey Stoney, great question! I wanted to answer you in your video, but you disabled comments. So I'll answer it here. Now, as we have observed, our galaxy is just one of many. From what we can observe from our galaxy, all the galaxies that we can see are moving away from each other. So this tells us that there is a central point that they are all moving away from. Now we can not observe this point, but it must be there for everything to be moving away from. You may be right, it might be empty.

  • "So this tells us that there is a central point that they are all moving away from. "

    No it does not. If every galaxy move away from all others no central point is required or even meaningful to talk about.

    Think about it like dots on a balloon that is filled with air and stretched out. All dots move away from each other with no central point. The universe is like that (but three dimensional, of course).

  • Yes, this is technically correct, but there is still a central point: The Big Bang Singularity. While it is true that we are describing an expansion of space-time, which your example describes more accurately, it is also true that I am merely trying to give a very generalized description.

  • Yes, I understand that you try to generalize but, technically, if the singularity was a "central point" we are still in it, only the singularity expanded to become the universe we live in. The concept "outside the singularity" make no sense so calling it a "central point" makes no sense either.

    The BB theory is in may ways mind-boggling because the physics, or rather the conditions where the physics apply, is so far from our experience that "common sense" is totally useless.

  • And I completely agree. This is one of those things where a 500 character explanation simply will not do the subject justice. I think that I have explained the concept sufficiently in a general sense to disabuse stonedcommander of many of the misconceptions that he had. And that was really the whole point of my original comment.
