The most distant galaxy ever measured Video.
Astronomers using ESO’s Very Large Telescope (VLT) have measured the distance to the most remote galaxy so far, UDFy-38135539, existing when the Universe was only about 600 million years old (a redshift of 8.6). Image: M. Alvarez, R. Kaehler, and T. Abel
(PhysOrg.com) — A European team of astronomers using ESO’s Very Large Telescope (VLT) has measured the distance to the most remote galaxy so far. By carefully analysing the very faint glow of the galaxy they have found that they are seeing it when the Universe was only about 600 million years old (a redshift of 8.6). These are the first confirmed observations of a galaxy whose light is clearing the opaque hydrogen fog that filled the cosmos at this early time. It has taken 13.1 billion years, travelling at 300,000 kilometres (186,000 miles) per second, for this smudge of infant light to arrive

Running away
The distance to faraway galaxies is measured by noting how rapidly they are moving away from our own. Because the universe is expanding at an ever-increasing pace, all widely dispersed galaxies retreat from each other at greater speeds the farther apart they are.
Scientists measure all this by noting a galaxy’s redshift, the extent to which the wavelengths of its light have been stretched toward the red end of the spectrum during its long travels across the cosmos.
The previous record holder, a Sloan galaxy, is at redshift 6.4.
The newfound galaxy has a redshift of at least 6.6, based on the Hubble imaging, and may be near 7.0 according to a less firm analysis of the Keck observations.
The universe is now about 13.7 billion years old.

Astrophysicists: Time, universe will end in 3.7 billion years.
Image via Wikipedia According to Indian Philosophy, the period in question is 3.1 Billion years (appx) Time is Cyclic , not linear. “TIME- Calculation in Hindu Philosophy.Story:According to a team of United States and Japanese astrophysicists, they say there is a 50 percent chance that the end of everything as we know it will occur in approximately 3.7 billion years, reports Agence-France Presse.The inevitable conclusion of our universe’s existence will transpire because of the expansion of the universe. Although scientists generally agree that the universe expanding can occur for an infinite period of time, the team of researchers say the rules of physics state that an eternal inflating universe is unlikely. “The point of this paper is to show that certain methods and assumptions that have been widely used by physicists for years — most prominently, the use of a time cutoff in order to compute probabilities in an eternally inflating universe — lead to the conclusion that time will end,” said Raphael Bousso of the University of California. “In other words, the time cutoff, which we may have thought was just a calculational tool, actually behaves like a physical event, whether we like it or not.”Read more: http://www.digitaljournal.com/article/299119#tab=comments&sc=0&local=#ixzz12vJpMvkn

And as their Large Hadron Collider (LHC) at CERN near Geneva moves into high gear, they are talking increasingly of the “New Physics” on the horizon that could totally change current views of the universe and how it works.
“Parallel universes, unknown forms of matter, extra dimensions… These are not the stuff of cheap science fiction but very concrete physics theories that scientists are trying to confirm with the LHC and other experiments.”

iPhone in Space ,incredible video .
http://www.huffingtonpost.com/2010/10/16/father-and-son-send-iphon_n_765369.html
A father and son from Brooklyn, New York sent an iPhone into the stratosphere a few weeks ago to record a video of the earth’s curvature.
The two spent eight months researching and testing their homemade craft, which was made of a weather balloon and a styrofoam case for the iPhone, before launching in Newburgh, NY.
The phone apparently braved winds of 100 miles-per-hour and temperatures as cold as 60 below zero (the iPhone was smartly packed with hand warmers).
The recorded video shows the phone reaching a height of 100,000 feet before the balloon burst, plummeting the contraption back to earth, where it landed 30 miles from the launch point, in a tree, where the father and son found it in the dark because of the iPhone’s LED light.

String Theory and Indian Philosophy.
String theory 
Matter and mind differ only in degree not in kind. Greater the vibration it is Mind; lesser , matter.
Based on various levels of vibration,there are 14 Levels of existence9Vishnu Purana).References are also available in Buddhism.
All thee different levels co existed, co exist and shall co exist at the same in a cycle.
Please read my blog TIME.
Story:
String theory is a developing theory in particle physics that attempts to reconcile quantum mechanics and general relativity.[1] It is a candidate for the theory of everything (TOE), a manner of describing the known fundamental forces and matter in a mathematically complete system. The theory has yet to make quantitative experimental predictions, which a theory must do in order to be confirmed or falsified.
String theory mainly posits that the electrons and quarks within an atom are not 0-dimensional objects, but rather 1-dimensional oscillating lines (“strings”). The earliest string model, the bosonic string, incorporated only bosons, although this view developed to the superstring theory, which posits that a connection (a “supersymmetry“) exists between bosons and fermions. String theories also require the existence of several extra, unobservable, dimensions to the universe, in addition to the usual four spacetime dimensions.
