| 1134048 | 2010-09-05 11:37:00 | F'rinstance::: I proffer the 'white noise' that is still bouncing around/in this universe from early-to-current radio/energy emissions from radio/TV/radar, etc, that can be measured and heard through audio devices as 'sizzle' or 'hash', and of course can also be seen when demodulated as the 'visual and aural noise' between broadcast channels on TVs. If there was no limit to the universe, (ie: boundaries) for the echo-effect and resultant bounce-back of these radiant forms of energy, then they would be seriously less or even non-existent, unlike what we have now and can see/hear and decipher. Think of it this way: you need some sort of wall or enclosure to create an echo in a canyon or large empty building; I see the universe as such but on a much grander scale. Sorry to kill that theory for you Joe, but the only signals you can 'demodulate' are those on a carrier wave and the moon is about as far as they can reliably bounce back from unless you have a rather large parabolic antenna. The visible noise (snow) and sound hiss between channels on a TV is simply random cosmic noise coupled with the internal noise from the amplifying devices in the equipment itself. Put a TV in a shielded room and turn it on and you will see the same snow on the screen. Similarly, turn on a radio in the same room and you will hear hash from the movement of electrons within the amplifying and tuning circuits. You see, when there is no signal input, all receiving equipment cranks itself up to full gain to see if it can find anything, and that's what creates the on-screen or audio noise. However, just supposing there was a boundary to the Universe, then given that radio waves travel at the speed of light, the 'boundary' would have to be no more than 40 light years away if you wanted to 'hear' noise from a 1930 broadcast radio signal (40 years out and 40 years to get back). To 'see' noise from a 1980 TV broadcast it would have to be no more than 15 light years away. You talk about current signals being reflected from the boundary?? Honey you just shrunk the universe to squat! We can see many times further than that with optical telescopes and further again with radio telescopes. I think the big problem is that man cannot comprehend infinity, any more than he can accept the brevity and finality of his own death. Religion is a triumph of fantasy over reality, and a monument to man's towering ego. That which man can neither comprehend nor explain, he deifies. Personally I believe that the turtle came first, in fact he had to, because he moves so slowly, and if the elephants had been there first, they'd have fallen off the edge of the universe as soon as they arrived because they'd have found nothing to stand on. This theory presumes that you believe in flying elephants of course. Cheers Billy 8-{) :illogical |

| 1134051 | 2010-09-05 12:35:00 | I think the Universe is so unimaginable gigantic that or brains cannot comprehend the enormous scale involved, and new discoveries like the vid shows keep on showing us there is probably even more scale than current science could imagine . Light travels at 299792 . 458 km /s now multiply that by 13000000000 years, each one with 31 556 926 seconds and thats only in one direction . Hubble can see an equal distance in the opposite direction as well . Another thing to take into consideration is the Red Shift . The further away galaxies are from us the more they seem to be moving away . When you get way out, they approach the speed of light and this effects the light we receive from them and spectrometers show their light shifts more towards the red end of the spectrum . Mind you the light we receive from them is 13 billion year old so they have had plenty of time to continue to speed up to beyond the speed of light, so would be no longer visible to us in real time . So who knows whats out there? My point is you need the observations,data, evidence to be able to make a conclusion and as far as the Universe is concerned we don't have much evidence except its big . All we have is theory and philosophy . Face it, some things are just to big to make any sense of at the moment, let alone measure . Maybe in another 10,000 years when we're grown up(if we survive that long) Thats my perspective . |

| 1134052 | 2010-09-05 13:48:00 | Well, it's like this...the Universe is made up of many worlds. Each world travels through space on the backs of four elephants that stand on the back of a giant turtle. api.ning.com 59lE-w6y2njk7lK-LCg3*zKlIV31m0uOjZxSScdT1v*8fX/GreatATuinsmall.jpg www.terrypratchettbooks.com There are some people who have a legend that the whole universe is carried in a leather bag by an old man. They're right, too. Other people say: hold on, if he's carrying the entire universe in a sack, right, that means he's carrying himself and the sack inside the sack, because the universe contains everything. Including him. And the sack, of course. Which contains him and the sack already. As it were. To which the reply is: well? |

Then again it could have the entire universe at the bottom of the well | gary67 (56) | ||

Wasn't there an old movie about someone who dug a well and there were people living deep in it and they established a form of communication with a woman - and the most important line in the movie was something like this: "We call it chicken" . |

| 1134056 | 2010-09-06 00:50:00 | Well , I'm impressed , Billy T , very sensible , logic is a very powerful tool in a sharp mind. With a little bit of real knowledge on the subject. Ppd , you made far more interesting reading by putting it in your own words, some of us are on dial-up and hate having to go and load another page. The red shift , I have a theory that the red shift is caused by gravity not things moving away. Our sun is supposed to be red shifted??? |
