art star. Demolition Lover Age: 31 Gender: Female Posts: 19017 | there's a theory that the universe expands and contracts... ...and the contaction is responsible for the feeling of deja vu. i don't know. it's just some thoery. |
Oxycontin Genocide. Banned Age: 29 Gender: Male Posts: 2955 | xrated_romance: Wow, that's an interesting way to look at things! I have llike deja vu alot. It's really weird. |
konton. Always Born a Crime Age: 32 Gender: Female Posts: 5642 | I don't know why, but I have a REALLY hard time believing in the fact that the universe is endless. |
abeautifuldisaster Killjoy Age: 31 Gender: Female Posts: 39 | Oxycontin Genocide: deja vu really is all in the mind. it has been proven scientificaly. every thing you have ever seen, felt, touched exc. has been chizzled on to your brain. even from you moment of birth. we just don't "remember" it all. things are brought back when stimulated by a later touch, sight, feeling exc. the same with deja vu. when a certain memory is stimulated by a certain scence, it creates the feeling of somthing having happened before. it is really your mind playing tricks on you. it does the same thing with dreams. dreams are messages from you entire lifetime being mixed up into one experience. yeah. its hard to believe that it goes on forever. but than again alot of stuff we can't see yet we still believe in it. a few hundred years ago people couldn't even imagine that anything like bacteria could exsist. they never imagined that there was a whole other world of things that we can't even see right under their noses. i guess that is kinda like the universe. is is just me or does the thought of FORVER make you feel a tad bit overwealmed, maybe even a little sleepy? |
Diana_a7x Thinking Happy Thoughts Age: 31 Gender: Female Posts: 456 | Well like a lot of people have posted, The world is a huge place. I do think though that we will know how big it is. I think the question is, who will take their time to do it? |
blow Bleeding on the Floor Age: - Gender: Female Posts: 1137 | The universe is endless. I like to compare the universe to the internet, because as far as I know the internet s endless as well. You can store millions of gigabytes in it and still have room for more. That's probably a faulty metaphor, but it makes sense to me. I believe there are pararrallel worlds out there (not multiple universes, like Reinvent Love said, the universe is everything, so there can't be more than one.) but perhaps there are other 'worlds' that exist side by side with ours, but separate. I don't know, it's a crazy idea. |
Rexperience Bleeding on the Floor Age: 32 Gender: Male Posts: 1052 | So far as I know, we are living in a 4 dimensional Universe that is pretty flat, yet warped due to the gravity of its heavenly bodies and constantly expanding. (Which means there truly is always room for desert) Just for Reference of size, I calculated the diameter of our Milky Way Galaxy is 588 Quadrillion miles long, thats 588 with 15 zeros! And thats just our galaxy, not to mention any other larger galaxies, or clusters or super-clusters. Theres a lot of space out there... Also the faintest star in the night sky isn't a star at all, its our closest neighboring galaxy: Andromeda. The light you see when you look at it is ancient light, meaning its taken 2.9 million years to get to earth. So when the light you are seeing now started traveling, humans didn't even exist! For more in depth info on the Universe and the laws that govern it please read "A Briefer History of Time" by Steven Hawking and watch documentaries "The Elegant Universe" and "What the Bleep!? Down The Rabbit Hole" I highly recommend them all. |

fawkes Bleeding on the Floor Age: - Gender: - Posts: 1131 | I think that there's space, which goes on forever. The universe only takes up part of that, and if the big bang theory is true, it probably is spherical (or maybe not?), expanding from one point. There could be other universes too. And there could be other dimensions besides length, width, height, and time that we can't sense. |
blow Bleeding on the Floor Age: - Gender: Female Posts: 1137 | fawkes: Like string theory? If anyone here understands string theory I would love to have it explained to me in simple terms. It's intriguing, but I have no idea what it's saying. |
fawkes Bleeding on the Floor Age: - Gender: - Posts: 1131 | Faraday: I think so. We learned about something like that in my physics class. I sort of understood it, but I have no idea how to explain it. |
xxZalanortxx Killjoy Age: 28 Gender: Male Posts: 79 | I think that there is quite a good chance that other dimensions, and possibly even alternative realities and other planes of existence exist. |
blow Bleeding on the Floor Age: - Gender: Female Posts: 1137 | xxZalanortxx: Were did you hear this? The universe is all matter and energy, it is everything by definition. There can not be more than one universe. xxZalanortxx: Most say there are ten or eleven dimensions to the universe, but the number could actually be infinite. Of course this isn't the kind of dimensions you're talking about. |
blow Bleeding on the Floor Age: - Gender: Female Posts: 1137 | ^Im going to bookmark that. There's a bunch of videos with parts of Carl Sagan's Pale Blue Dot, they are very humbling to watch. |
xxZalanortxx Killjoy Age: 28 Gender: Male Posts: 79 | Faraday: I heard and read about it on the Science Channel, Scientific American, and a few sites on the internet. I know it sounds confusing, as the definition of "universe" is supposed to mean everyting, but it is a real theory. It was adopted in some cases, as an alternative to the expanding universe theory, and in others (the one I agree with) to go hand in hand with the theory. |
blow Bleeding on the Floor Age: - Gender: Female Posts: 1137 | xxZalanortxx: hmmm... But what does it mean that the mass of the universe does not add up? |
xxZalanortxx Killjoy Age: 28 Gender: Male Posts: 79 | What they meant by "the mass of the universe does not add up", is that their has to be a specific amount of mass in the universe for gravity, aerodynamics, and essentially every known scientific theorem to exist and function properly. Through some complex mathematical equation, they were able to find what the presume is that magical number to allow everything in the universe to function as it does. Well, then they added what is estimated to be the total mass of our universe. It wasn't the amount required. They eventually looked at if there were other universes, would it add up? They went through the similar process of the previous mathematical equation, and then added in multiple factors such as the distance between them. The result was, that with a certain number of alternate universes (presumably five) they could reach that number. |
blow Bleeding on the Floor Age: - Gender: Female Posts: 1137 | xxZalanortxx:I looked this up and there's actually another explanation that I find more feasible. The presence of dark matter and dark energy would account for the gap between normal mass and the 'magic number'. I think it's more possible that there are unknown substances in the universe that we have not discovered than parallel universes. This explains it: Dark Matter: |
xxZalanortxx Killjoy Age: 28 Gender: Male Posts: 79 | Umm.. Faraday, dark matter is actually is actually most commonly identified with anti-matter. I black hole, for example is composed of (depending on your point of view) dark matter or anti-matter. Anti matter is a constant implosion, hence sucking all other materials into it and practically disintegrating it. This doesn't seem like it would add to the equation. It seems as though it would only take away. |
blow Bleeding on the Floor Age: - Gender: Female Posts: 1137 | xxZalanortxx: I think you're incorrect. Dark matter and antimatter are two completely different things. Antimatter has been created in laboratories and we know what it is. Dark matter is an unknown substance, we don't know what it is, what it's made of, or how it works. I've read a lot on dark matter and nothing I've read says that it is related to antimatter or is anymore present in a black hole than regular matter. Nasa.gov: If black holes contain no matter then dark matter cannot be present in a black hole simply because it is matter. Wikipedia: Nasa.gov: csep10.phys.utk.edu: newton.dep.anl.gov: |
