| Posted By: Owen T Posted On: Jul 25, 2006 Views: 1742 | It's a Small......Universe I would just like to point out that in an atom you obviously have the neutrons and protons in the centre and the electrons flying round the outside...In the space between the electron(s) and the neutrons & protons...there is nothing..in fact I think that as much as 99% of an atom is nothing...Hard to get your head round maybe...but this then means that 99% (or a similar amount) of the universe is nothing! Anybody's thoughts? P.S. I'm not entirely sure it is exactly 99% but I know it is a number near to this |

| Posted By: Owen T Posted On: Jul 25, 2006 Views: 1739 | RE: It's a Small......Universe Thanks...Also i wanted to clear up something else....If distant galaxies are moving away from us, as if being "stretched" like dots on the surface of a balloon being inflated, and galaxies further away from us are moving faster away and ones nearer are moving slower, as if in proportion, does that then mean that each atom in the universe is moving away from others...Even if it is an amount of space that is so small it is unmeasureable....Because the way I see it the "fabric of space" is moving apart, so to speak, not just distant galaxies...Or is it just that galaxies and stars are moving away from us? Thanks in advance.... |
| Posted By: Keith Mayes Posted On: Jul 26, 2006 Views: 1735 | RE: It's a Small......Universe It is the universe that is expanding, this does not affect the size or spacing of individual atoms, they remain constant. It does mean that galaxies are all getting further apart. |
| Posted By: Owen T Posted On: Aug 1, 2006 Views: 1728 | RE: It's a Small......Universe I still don't see why this is...If the universe is imagined as a plate of elastic that is being stretched and that is the reason for the galaxies moving further away from us and new space is being created then is it not true that even on a smaller scale things are moving apart from each other, even if it is a smaller distance? For example wherever space is created in the universe then it moves two points eiher side of that space further apart from one another? |
| Posted By: Keith Mayes Posted On: Aug 1, 2006 Views: 1726 | RE: It's a Small......Universe The universe itself is expanding, not everything in it. Get away from the idea of it being 'elastic' and stretching everything further apart. Imagine instead being in a swimming pool and more water is added, the volume of water would increase but the objects in it would remain the same. If you use the anology of painting dots on a balloon to represent the galaxies and then blow into the balloon it can be seen that the galaxies all get further apart as the balloon expands. The actual atomic structure of the painted dots does not alter however, the atoms remain the same. |
| Posted By: Owen T Posted On: Aug 2, 2006 Views: 1721 | RE: It's a Small......Universe But using the balloon analogy is exactly the same!!! I think Il have to make a quick diagram to show what I mean. |
| Posted By: Owen T Posted On: Aug 2, 2006 Views: 1720 | RE: It's a Small......Universe Thanks for calling me a dumb hypocrite as well!!Really appreciated it |
| Posted By: Keith Mayes Posted On: Aug 2, 2006 Views: 1717 | RE: It's a Small......Universe That was under a totally different thread and you deserved it! |
| Posted By: Owen T Posted On: Aug 2, 2006 Views: 1714 | RE: It's a Small......Universe w/e man, u want ppl 2 post on these boards or not? |
| Posted By: Keith Mayes Posted On: Aug 3, 2006 Views: 1710 | RE: It's a Small......Universe You said I must think that 0.999' is less than 1 because my teacher told me. You then went on to say that your teacher told you they were equal so you believed it. If that is not being a dumb hypocrite then I don't know what is. If you consider my telling the truth to be an insult that is your problem, deal with it. |
| Posted By: Owen T Posted On: Aug 3, 2006 Views: 1707 | RE: RE: It's a Small......Universe No you obviously didn't understand, as i wasn't clear enough. What I was trying to say was that I'd read in another thread (don't ask me where!) that you're teacher had told you 0.999' didn't equal 1, or it seemed like that. I was trying to point out that my teacher told me the opposite, which just proves that teacher's are not always right!!!! which is what i was trying to show and why i gave another example in my thread. |
| Posted By: Keith Mayes Posted On: Aug 3, 2006 Views: 1705 | RE: It's a Small......Universe That just goes to show the importance of reading a statement properly, comprehending it and not making assumptions. I have NEVER said anything about any teacher telling me anything, where you got that from I have no idea, I have not been to school for friggin years! Now, to get back on track... why do you have a problem with an expanding universe but static atomic structure? |
| Posted By: Owen T Posted On: Aug 3, 2006 Views: 1703 | RE: It's a Small......Universe lol yeah innit, seeing as it is such a better topic than the bloody 0.999' crap!!! Ah yes, well i will do a diagram for it, but simply, if we use the balloon analogy, and mark dots on the balloon to represent different galaxies, then I am fine with the fact that when you blow the balloon up, as is currently happening in the universe (yes?) then the dots will move further apart...And further, the dots will move in proportion to the distance they are away from each other i believe: 2 dots far apart from each other will move further apart, relative to 2 dots that are closer to each other. But, and this is where I've thought past the basic analogy, and thought that not only do the dots move further apart, the whole of the surface of the skin of the balloon is stretched. Which should mean that the dots stretch, ie get bigger....or easier put, one side of the dot will get further away from the other side of the dot. But even further to this, if you could draw an even smaller dot, on one of the dots, then that dot would be stretched as well, but the amount would be a lot less than the dots on the balloon moving apart, but still can you see where this is going? You could carry on forever judging smaller distances and noticing that the space between them was getting further apart. Now Im sure that on an atomic level and even within the confines of a planet, gravity and the force that holds atoms together will be enough to hold them in the same space constantly, even in our solar system... but surely within the Milky Way things are getting further apart? It's worth thinking about anyway.... Anyone's thoughts?! Where is everyone these days on the boards? |
| Posted By: Owen Posted On: Aug 3, 2006 Views: 1702 | RE: It's a Small......Universe P.S. ^^ Jus referring back to up there, the analogy doesn't matter if its elastic or a balloon, its the same thing....You know the one where you have a plate of elastic, and the heavier a planet or star the further it sinks into the elastic and that demonstrates its gravity...When the star or planet gets two heavy it rips the elastic....Hence the black hole? Was on horizon once i think...brilliant prog. |
