Re: APOD: Cosmic Microwave Map Swirls Indicate... (2014 Mar

just a note huge LQG spans 1200 Mpc, thats thats many magnitude of difference from the not well defined scale limit for homogenity , close to HUGE LQG is another LQG and they are close to sloan great wall all of these structures is in particular part of universe that make up 5% of mass of known univ...

Re: APOD: Cosmic Microwave Map Swirls Indicate... (2014 Mar

anyone care to explain why this exist http://en.wikipedia.org/wiki/Huge-LQG The linked article essentially answers the question: the scale of isotropy is not well defined. And it is statistical in nature. upper limit for the homogeneity scale in the universe is 260/h Mpc The Sloan Great Wall, disco...

Re: APOD: Cosmic Microwave Map Swirls Indicate... (2014 Mar

As a direct consequence of inflation, the Universe appears to be the same in all directions (isotropic) and the cosmic microwave background radiation is distributed evenly wikipedia http://en.wikipedia.org/wiki/Inflation_(cosmology) anyone care to explain why this exist http://en.wikipedia.org/wiki...

Re: NS: Largest structure challenges Einstein's smooth cosmo

its not a big deal ..homogenity is simple concept you dont need phd or whatever, i mean astronomy is not reserved for a clique of physicists ..these are the basic quesions and every human being should be concerned with this ...i wish carl sagan was alive today :( :(

support of people certainly helps ..physicists with different view don't feel singled out ..it also works the opposite way.

Re: APOD: Comet McNaught Over Chile (2013 Jan 27)

C/2011 L4 (PANSTARRS) most likely originated in the Oort cloud, a cloud of cometlike objects located in the distant outer solar system. It was probably gravitationally disturbed by a distant passing star :shock: , sending it on a long journey toward the sun1.

Re: POLL :fundamental questions about reality

The poll was useless, and demonstrates nothing of value. How quantum mechanics maps to "reality" may or may not even be a valid, answerable question. The fact is, the models utilized by quantum mechanics are useful: they are descriptive and predictive of nature, which is what we ask good ...
