KerrTexas Posted November 3, 2009 Share Posted November 3, 2009 Came across an article entitled " Rumors of a Strange Universe " today, thought I'd post the link here for those who might find the article interesting. Three years ago results were first presented indicating that most of the energy in our universe is not in stars or galaxies but is tied to space itself...

I'm still not 100% convinced. The evidence comes almost entirely from one source...distant Class 1 supernovas. There may yet be something other than acceleration of the universe expansion that is causing them to appear fainter than they 'ought' to be.

Angleochoas Posted November 10, 2009 Share Posted November 10, 2009 distant Forgive me if I'm way out of line (I didn't read the whole article), but upon first glance a couple of things seemed to make sense.Think of the amount of space for all the light to be dispersed between here and the originating point/s. My thought is, when we see the sun so bright, again obviously distance comes into play for proximity of travelling photons? 360 degrees at that (minus whatever immediate matter blockage is lessening/defracting as seen in the photo around it's equator. If the right matter or debris were immediately encircling the radiating body, could refraction so close cause any photon collision? I'll go read the article now before I make myself sound sillier Link to comment Share on other sites More sharing options...

Stuff like debris and dust tends to scatter light in a predictable way....so you can usually tell if there is such material between you and a star, for example.There are really only two possible explanations for the brightness discrepancy other than 'dark energy' making the universe accelerate. 1) The speed of light is changing. If the speed of light was slower in the past, then by definition less energy would be produced in nuclear reactions....and stars would be dimmer. 2) Space itself somehow absorbs energy over long distances.
