CHADS Posted February 10, 2005 Report Share Posted February 10, 2005 i was musing over an idea which basically looks at the stars we see in the sky ........... can any of them be the same star?I was looking at Orions belt and imagined the centre star of the trio producing the light of the other two ... Sure its unlikely that the belt stars are of the same star ... but the concept led me to try and rationalise such an event occuring . If for example a star radiated light in all directions and the light that travelled left came close to a black hole and was bent by 89.999999 degrees and travelled toward earth ... and similarly the light from the same star travelled right and encountered a different black hole , again bent at 89.99999 towards earth ... Would observers on earth see three stars ...... one bright .. and 2 red shifted ......... I say 89.999999 deg as im unsure to what extent a black hole can bend light if a tall ....and even if the light once bent would ever escape Any how the concept is simple is it possible that what we see in the night sky is a product of many of these black hole influences ......... that many stars are seen but there are infact less stars than we see ................... Like a hall of mirrors effect .... Of course our telescope observations would also be subject to illussion ... so could you even detect if its true or not.. Its probably that i dont know enough about what light can do .. or maybe theres something in it ......... please reply.... :) Link to comment Share on other sites More sharing options...
pgrmdave Posted February 10, 2005 Report Share Posted February 10, 2005 It is possible to determing the star's material through analysing the star's light. If two stars have exactly the same spectrum, I believe that it possible to determine the distance from the earth. If still the star seems the same, then it is possible, though not likely, that it could be the same star. Link to comment Share on other sites More sharing options...
alxian Posted February 10, 2005 Report Share Posted February 10, 2005 you said it yourself... :) because should orions belt only have one star then every nation on earth that noticed the formation was in fact not seeing three stars but the same one.. ... .. .. . i know i keep saying humans are dense but that would be too unbelievable a piece of evidence... (i might have to take myself seriously :D ) Link to comment Share on other sites More sharing options...
Buffy Posted February 10, 2005 Report Share Posted February 10, 2005 Science Fact! Uncle Albert first proposed it, and there's lots of evidence: take a look! http://images.google.com/images?q=gravitational+lensing&hl=en&btnG=Google+Search I'm not enough of an expert at the math, so I'll leave the question of 90-degree bending to someone who actually knows. I've never seen anything beyond some of the pics shown in the link above, but if the black hole was REALLY big (and really close I imagine), then it might appear majorly bent!

Tormod Posted February 10, 2005 Report Share Posted February 10, 2005 I don't know about single stars, but there are examples of galaxies which are observed twice. This is due to gravitational lensing, which means that the light from a galaxy is bent around another object (another galaxy, for example) so that half of the light passes on one side, the other half on the other side (oversimplification). It will appear as two galaxies, but it will be the same. This has led some to ask whether the universe actually is much smaller than what we think. Maybe a lot of the galaxies are simply repeated, like in your "hall of mirrors" analogy. Such a study was indeed performed, and showed no evidence of this. http://www.msnbc.msn.com/id/5051818/ Link to comment Share on other sites More sharing options...

alxian Posted February 10, 2005 Report Share Posted February 10, 2005 i meant hit a tab such as add url link and voila picture is inserted no outside app required. a popup appears within which you draw you doodle and hit close, this then serves as you piclink, again no outside app required.

Tormod Posted February 10, 2005 Report Share Posted February 10, 2005 No, there is a button which lets you insert an image URL but there is no drawing app, no. Link to comment Share on other sites More sharing options...
Tormod Posted February 10, 2005 Report Share Posted February 10, 2005 Cool idea, though. Have you seen something like that? Link to comment Share on other sites More sharing options...
alxian Posted February 10, 2005 Report Share Posted February 10, 2005 i haven't thats why i sugg'd it. this forum is midway between generic and the lustastic http://www.whirlpool.net.au, hopefully this forum will reach that level of hotness.

Tormod Posted February 10, 2005 Report Share Posted February 10, 2005 I'll take that as a compliment. :) And the whirlpool forum is completely custom built, whereas our forums are built on generic software (although we have customised it quite a bit).

alxian Posted February 11, 2005 Report Share Posted February 11, 2005 i wonder if they will create a kit and license their style, (whirl) few other forums compare. Link to comment Share on other sites More sharing options...
Tormod Posted February 11, 2005 Report Share Posted February 11, 2005 LOL...their FAQ actually states something like "No licensing offers will be accepted". :cup: Link to comment Share on other sites More sharing options...
