| 1484025 | 2022-02-01 20:31:00 | "Mankind understands much about the Universe and how it came about but not why or what its final state will be especially since latest observations show the expansion is speeding up which makes no sense." Man doesnt know that much about the universe. Just in my lifetime so many theories proved wrong by observations Dont know : Why it popped into existence, dont know why expansion is speeding up, dont know if constants are constant every where & at all times, dont know why constants have the values they do, dont know if there are multiverses etc etc . Mankind make up dark matter & dark energy because we dont know why , there are just a best guess We only know what we can see. We cant see so much of it . "It has to be a continuous process which is repeating forever." You are putting human emotions into this, same as when Einstein refused to believe anything but steady state It doesnt have to be anything . It just is and we dont know why . "It can't be solid nothing and it can't be solid everything because either is a completely predictable state and that violates the Uncertainty Principle which is derived mathematically and is known to be correct. " ? The uncertainty principle is " that we cannot know both the position and speed of a particle" The uncertainty principle doesnt matter much on the macro level . My cat is both dead and alive when its hiding in a box . It doesnt really apply at the macro level . its all just a collection of fields anyway , and it could all be just a simulation . |

| 1484026 | 2022-02-01 21:26:00 | My mind is very far from being the sharpest knife in the box and I am unable to believe in the big bang theory. I cannot conceive that suddenly after nothing, something just exploded and we now have an expanding Universe, so big that we cannot see the end of it even with the best of devices we can design to try and do so. Some of the great minds believe in the big bang but I wonder if they have fallen into that belief just because someone else thought of it first? |

| 1484027 | 2022-02-01 21:39:00 | Another thing to contemplate is, is the Universe like a ball? If so is it in a void of nothing as it expands? And, where does the Milky Way lie in the Universe, certainly it isn't the centre so we must be closer to one edge of the ball than to another edge. | Bryan (147) | ||
| 1484028 | 2022-02-01 22:55:00 | There is no void, that's in your mind, (like zero and infinity, a mind construct) the huge sphere shaped ball of galaxies composed of stars is not expanding into space, space is expanding with it. What's more the latest measurements show that the expansion is speeding up which makes no sense. The Big Bang did happen but the question is what set conditions up in the first place for it to happen, and how will it end? As I said, a one-shot Universe says that God made it which is nonsense. It has to be something changing its form and state which has always existed and always will, things can't exist then cease to exist or magic is involved, ie nonsense. I covered this is my previous writing above but of course some things are hard to understand and express succinctly. As I said before, it is composed of not nothing and not everything the answer lies somewhere in the middle of nothing and everything and what you see around you now is one form of how that manifests. Best way to look at is is as a great work of art which is totally pointless and almost completely meaningless. LoL That is: The Cosmic Joke LoL |

Instantaneous combustion I can understand, as having worked for a feedmill, where they had stacks of linseed and these seeds were not completely dried off, and caused an explosive fire, therefor someone must have stacked the sacks to tightly. lurking. |

| 1484030 | 2022-02-02 19:24:00 | And, where does the Milky Way lie in the Universe, certainly it isn't the centre so we must be closer to one edge of the ball than to another edge. en.wikipedia.org earthsky.org But through a telescope, we see the Milky Way for what it truly is: a spiral arm of our galaxy. Our solar system is located about 2/3 of the way out from the Galactic Center toward the edge of the galaxy. We are, in fact, 26,000 light years from the center, or 153,000 trillion miles (246,000 trillion km). And www.space.com Filaments...oh er.... |

| 1484033 | 2022-02-02 23:59:00 | By definition there is only one Universe, if there are multi-verses then they are contained in the Universe which we just made our definition bigger to fit all the rest in. Once upon a time not so long ago, (1920's I think) we thought that the Milky Way was the Universe; but soon nebulosities or fuzzy stars were noticed in amongst the observed stars and these turned out to be other galaxies made up of millions of other stars further away than the local galaxy stars so our definition of Universe was expanded. |

| 1484034 | 2022-02-04 02:25:00 | Or are we seeing the same stars more than once.? Einstein once said that if we had a telescope powerful enough, we could see the back of our head. www.quora.com |
