This means that the light that composed the image travelled 13 billion light years, and hence the source is currently ~13 billion light years away. If we say that the universe is 13.7 billion years old, then the observable universe is roughly 13.7 billion light years in radius.

In an expanding Universe this distance NOW is larger than the speed of light times the light travel time due to the increase of separations between objects as the Universe expands.

Yes! Stockton (1978, ApJ, 223, 747) observed faint galaxies near in the sky to bright quasars at moderate redshifts. He chose quasars with moderate redshifts so he would still be able to see galaxies at the redshift of the quasar. He found that a good fraction of the redshifts of the faint galaxies agreed with the redshifts of the quasars. In other words, quasars are SaMhAcKeRhttp://www.blogger.com/profile/13708883781541208252noreply@blogger.com0tag:blogger.com,1999:blog-7857889996295004427.post-9750893243129206492011-03-15T05:53:00.003-07:002011-03-15T05:53:44.128-07:00Has the time dilation of distant source light curves predicted by the Big Bang been observed?This time dilation is a consequence of the standard interpretation of the redshift: a supernova that takes 20 days to decay will appear to take 40 days to decay when observed at redshift z=1. The time dilation has been observed, with 5 different published measurements of this effect in supernova light curves. These papers are:

1. Redshift with DistanceIt is a remarkable coincidence that there are actually two ways that you get a redshift with distance. Only the big bang explanation was considered which is the most complicated explanation, the most simple explanation was never considered because it depends upon the recently discovered wave SaMhAcKeRhttp://www.blogger.com/profile/13708883781541208252noreply@blogger.com1tag:blogger.com,1999:blog-7857889996295004427.post-66391850584957477542011-01-25T02:57:00.000-08:002011-01-25T02:57:30.250-08:00Our Finite Spherical 'Observable Universe' exists as part of Infinite Eternal Space.BY: Geoff Haselhurst - Karene Howie
The most simple explanation is that only one thing exists, space, thus it is necessarily infinite and eternal. From this most simple foundation we can then deduce that matter must be formed from waves in Space, where the electron is a spherical standing wave. The wave center forms the 'particle' effect, the SaMhAcKeRhttp://www.blogger.com/profile/13708883781541208252noreply@blogger.com0tag:blogger.com,1999:blog-7857889996295004427.post-45916816610407611402011-01-22T21:09:00.002-08:002011-01-22T21:09:51.259-08:00Three Ways the World Could EndThe apocalypse has always been the subject of Hollywood intrigue. From asteroid impacts, solar flares, and alien invasion, doomsday has been depicted in a variety of ways since the dawn of cinema. Although many of these films are produced for entertainment value with spectacular special effects, many scientists agree that there is a distinct possibility that one day the world may end in SaMhAcKeRhttp://www.blogger.com/profile/13708883781541208252noreply@blogger.com0tag:blogger.com,1999:blog-7857889996295004427.post-30389719184371173972011-01-22T21:09:00.000-08:002011-01-22T21:09:06.751-08:00Know the 4Cs and Save Money on Diamonds and on JewelryDiamonds prices are determined primarily by what gemologists and jewelers refer to as the 4 C’s – carat, color, clarity, and cut. Carat refers to weight and is equal to 200 mg – about 0.007 ounce. For comparison, an average size paper clip weighs about one gram, or 1000 mg, so five one carat diamonds weigh about the same as a paper clip. For wedding rings the one carat diamond is a popular choiceSaMhAcKeRhttp://www.blogger.com/profile/13708883781541208252noreply@blogger.com0tag:blogger.com,1999:blog-7857889996295004427.post-50310544309194528352011-01-20T21:11:00.003-08:002011-01-20T21:11:54.919-08:00newton letter over dualitya) How does matter exist as a discrete particle in Space and move through the Space around it?As Born explains;
One obvious objection to the hypothesis of an elastic Aether (Space) arises from the necessity of ascribing to it the great rigidity it must have to account for the high velocity of Waves. Such a substance would necessarily offer resistance to the motion of SaMhAcKeRhttp://www.blogger.com/profile/13708883781541208252noreply@blogger.com0
