chemistry_geek said:Hmmm....that's a tough question....I used to ask my mother and father those kinds of questions when I was 4 years old. When I was old enough to read, my mother bought me a book titled "Tell Me Why". That book explained everything, almost, it didn't explain the origin of the universe. But getting back on topic, I think the poll should have included "By design", meaning that an "intelligence" or "order" created the universe. I recall reading a recent physics article, gosh, I can't think of the name of it, but it involves some heavy players in physics. Any way, the article mentions that if some of the constants in the universe were just a little different, everything would be drastically different. This is what I mean by "by design". It doesn't imply a god-like supreme intelligence created the universe, but it basically says that "it is the way it is because things work that way, the only way". Personally, I do believe in God, and that He created the universe, but I also believe that it is by design in the terms that I describe.
There are a few astronomy programs out there, one in particular lets you cruise around the solar system and the local universe. Even moving at the speed of light, the stars don't move like you see in Star Trek. For that, you have to be traveling several hundred to several thousand times the speed of light. This gives you an idea of the immense distances in the universe. When you look at the images from Mars sent from Spirit and Oportunity, the images from the Voyager and Pioneer spacecraft, think about this: Earth is the only planet where the environment is just right to foster life. Temperatures, atmospheric pressure, the variety of all of the elements, the amount of water to sustain life and drive the air currents, the atmosphere protecting us just enough from ultraviolet radiation. THAT is something to ponder. And after you've ponder THAT, ponder about your own consciousness, how you came to think about the universe after reading this thread. Ponder about your thinking processes, and how they're geared to mesh well contemplating the universe.
Some ancient oriental wiseguy once said "The beginning of understanding comes when you learn to think with your heart and feel with your mind." (or reason or brain or however is the best way to translate that inscrutable oriental wiseguy ancient language.)MBHockey said:Evolution gave you a brain; use it.
JohnnyV said:How can "A natural event unaided by any intelligence" occur if there is no nature to speak of? Before the beginning there was nothing, can something come from nothing? Is it possible that God has a God? Where did God come from? As a supreme being has he always existed?
Arden said:The best explanation I have heard for the beginning of the universe is that it started at the Big Bang after a previous universe collapsed on itself, and ours will eventually collapse on itself as well, producing another Big Bang and another universe...
That would only be true in a "flat" euclidean kind of space ... you go father and father ... ehm ... further and further away from the origin of the x-y-z axes and matter gets spread thinner and thinner ("like butter that has been scraped over too much bread"). But WHAT IF space isn't like that and it would be more like the surface of a sphere? Matter would keep expanding, but then going around the fictional equator of this sphere, conglomerate again and maybe give rise to another big bang ... I'll leave it to the physicists to argue the whether and how ...The other theory is that the universe expands forever until all matter and energy becomes uniformly distributed and thus, very cold.
octane said:That is part of two competing theories; will the universe end in fire or ice?
Satcomer said:IMHO, that one is easy. Sir Isaac Newton has already the answer. It's called Gravity. Besides, we'll all be long gone before we collide with another Galaxy.
Arden said:Yes... the current theories state that, rather than matter moving fartherno, furtheraway, as would corks floating in water, spacetime itself is actually expanding and matter is simply expanding with it, like the image on a balloon.
Too late & too tired to go into detail with this...
Cat said:Torus or sphere would imply that there are no boundaries, but simply that you cannot "lift off" the surface. On the surface itself, of course, you can go everywhere without ever meeting a wall or something like that. However, keep in mind that the examples of Hawking likely mean that the space-time continuum is "shaped" in a certain way (it is still a model so don't take it too literally), not just the spatial universe.
