From the rate of expansion, when this point in time occurred could be estimated: about 10 - 15 billion years ago. If a source of light is moving closer, its colors are shifted up in frequency, toward the blue end of the spectrum; if the source is moving away, its colors are shifted down, toward the red. Such observations have resulted in the current "crisis in cosmology" which begs for the Big Bang theory to be replaced with another cosmological model. In astronomers announced that the Great Attractor appeared to be two extremely dense superclusters of galaxies stretching million light-years across the universe beyond Hydra-Centaurus. Inflation: The Universal Cure-All During the late 's - early 's, the subject of the extraordinary flatness of the universe, the unbelievable balance of the cosmos between runaway expansion and utter gravitational collapse, posed an incomprehensible problem.
This concept of the beginning of the universe came to be called the "Big Bang" model, according to which the universe began in a sort of explosion, starting out from infinite density and temperature, and then expanded, thinned out, and cooled. This microlensing event, discovered by Griest of University of California, San Diego, is the first direct evidence of dark matter. The Big Bang model logically follows from Einstein's theory of gravity to provide a mathematical description of the universe. But by June, the same team said that their findings could have been altered by galactic dust getting in the way of their field of view.
If wee see the universe at roughly vision then we see that all matters are equally distributed in all direction in the universe.

Alice shows Leonard her own comic. Is it hard being a boy today? This graphic shows a timeline of the universe Big bang book on the Big Bang theory and inflation models.
This change in color of cosmic objects is known as "redshift. The non-verifyiability of the inflation theory has been a major flaw from its inception: throughout the history of science the best theories have always made verifiable predictions, which could be tested by experiment or observation.
There's no way for extraterrestrials on that galaxy to communicate with us, to send any signals that will reach us, once their galaxy is moving faster than light relative to us.
If omega were greater than 1, then the universe would be closed and the expansion would or should already have come to a halt. There were certain books that I have read about child development, but mostly I relied on friends with older kids or a family therapist.
Honestly, cleaning brings me joy. For instance, gravity working alone would have taken something like billion years to create the supercluster two and a half billion light-years across that was recently discovered by American and German observers.
Redshift What has been perhaps the most troubling aspect of the Respiratory Universe model is the abundance of redshift in the cosmos. Penrose, R. From this speck emerged all the matter, energy and empty space that the universe would ever contain, and all that raw material evolved into the cosmos we perceive today by following a strict set of scientific laws.
May be it negatively curved like a saddle and infinite in extent. Selected References 1. Black holes, like the universe before the Big Bang, condense into a singularity.
This theory eliminated bubble walls as a major worry: the walls would be so far beyond our observational reach of about 15 billion light-years that they could never possibly become visible. Researchers think most of the cosmos is made up of matter and energy that cannot be "sensed" with conventional instruments, leading to the names dark matter and dark energy.
Planck's observations, first released inmapped the background in unprecedented detail and revealed that the universe was older than previously thought: Horizon and Flatness Problems The Respiratory Universe model would easily explain the horizon problem, since the universe, having practically existed for infinity, would have plenty of time to exchange heat and energy.
Today the long odds are that the Big Bang never happened. He viewed creation as a scientist, and when he was called to discuss creation's biggest puzzles — Where do we come from? He proposed that as the universe cooled, the instantaneous false vacuum created by supercooling had driven the expansion: the universe would have done it all by itself; there would be no outside force; no hand of God; no divine creative power was necessary.
Since the early 's it had been thought that neighboring galaxies were speeding away from Earth as determined by what is known as the "Doppler Shift," which is evidenced by the "redshift" of light waves.
Unknown objects, they were so they were called "quasi-stellar radio objects," or "quasars. According this theory gravity is no longer described by gravitational field but rather it is distortion of space time itself.

The Big-Bang Theory According to big-bang theories, at the beginning of time, all of the matter and energy in the universe was concentrated in a very dense state, from which it "exploded," with the resulting expansion continuing until the present.
This big bang is dated between 10 and 20 billion years ago, most likely c billion years ago.
