"Complex Life was Possible in Cosmic Afterglow Just 15 Million Years After the Big Bang"

Did Alien life thrive in the Big Bang afterglow? A set of calculations -standard adiabatic cold dark matter (ACDM) cosmology- suggests that the first star forming halos within the Hubble volume started collapsing at redshifts allowing liquid water chemistry— a pre­requisite for life — to form on rocky planets just 15 million years after the Big Bang regardless of their distance from a star. According to Abraham Loeb, an astrophysicist at Harvard University, in the early Universe, the energy required to keep water liquid could have come from the cosmic microwave background, the afterglow of the Big Bang, rather than from host stars. 

The very early universe was filled with superheated gas, plasma, that gradually cooled and condensed to form stars and galaxies. We see the first light emitted by this plasma as the Big Bang afterglow, cosmic microwave background (CMB), which today just a few degrees above absolute zero. Loeb calculates that about 15 million years after the big bang, the radiation would have kept the entire Universe at 300 kelvin  making it a vast habitable zone --"an incubator for life.” 

Our current understanding of the early distribution of matter is incomplete, says Loeb. Standard Big Bang cosmology says that in most parts of the universe, the amounts of heavy elements needed to make planets didn't occur until hundreds of millions of years after the big bang. But rocky planets could have existed in pockets of the early Universe where matter was exceptionally dense, leading to the formation of massive, short-lived stars that would have enriched these pockets in the heavier elements needed to make planets. He suggests that there would have been a habitable epoch of 2 million or 3 million years during which all rocky planets would have been able to maintain liquid water, regardless of their distance from a star.  

"These planets are very rare objects that are extremely unlikely, but because the universe is so large, you could still have them," Loeb says. 

These planetary systems would have to be very stable from a very early stage to give life a chance of emerging.

Many of our greatest scientists have been asking why does the universe appear to be "fine-tuned" for life? The logic behind this question, sometimes known as the anthropic principle, says that's why we are here today, able to study the universe and learn about its laws, that the fundamental constants in the universe are tuned in just the right way for us to be around to observe them. But if any of these constants were slightly different, we could never have come in to exist in the first place.

"The anthropic argument gives us an excuse for not seeking a more fundamental understanding," says Loeb, which makes the notion of "big bang life" appealing. The denser regions of matter needed for it to arise would have also required a cosmological constant a million times larger than ours. That would mean life existed in our universe even at a time when the value of the cosmological constant would have precluded the existence of humans, negating the anthropic thesis.

 

Christopher Jarzynski, a biophysicist at the University of Maryland, reports the journal Nature, is not convinced that life could exist in a uniformly warm Universe. Life on Earth depends thermo­dynamically not only on the heat source of the Sun, but also on the cold cosmic microwave background, which provides a heat sink, he notes. “Life feeds off this,” he says.

Alexander Vilenkin, a cosmologist at Tufts University, issued the most logical hole in the Loeb hypothesis "that a few million years is too short a time to produce intelligent life." And the statistical odds of it happening are so low, and that most life in our universe should be suited to today's small cosmological constant, that from a statistical view the anthropic principle remains valid.

The stellar furnaces in this massive cluster of galaxies shown in the image at the top of the page had transformed light elements into heavy ones. In the image, individual cluster galaxies can be seen at optical and near-infrared wavelengths, shown in red, yellow, and green colors. X-ray data (in purple) reveal the hot intracluster gas, enriched in heavy elements.

The galaxy cluster lies nearly 9 billion light-years away ... and so existed at a time when the Universe was less than 5 billion years old. A measured mass of more than 200 trillion Suns makes this galaxy cluster the most massive object ever found when the Universe was so young. The cluster elemental abundances are consistent with the idea that most heavy elements were synthesized early on by massive stars, but current theories suggest that such a massive cluster should be rare in the early Universe.

Comments

For Loeb to imply that his finding has anthropic significance is
laughable. The anthropic principle concerns the evolution of
intelligent life, and his two million year time frame is
less than 1 percent of the time needed for that.
See my widely read blog post that criticizes the claims in Loeb's paper:
Could Life Have Evolved in the Very Early Universe?
http://www.futureandcosmos.blogspot.com/2013/12/could-life-have-evolved-in-very-early.html

“...liquid water chemistry— a pre­requisite for life ...” ! When are we going to escape this “life equals water” straightjacket? What about, ‘life equals organized sentience’...in whatever medium facilitates/permits sensory transmission?

Big Bang ..Big Bullsh*t - Astronomical Redshift is an Artifact of Distance!

The Big Bangers, Sagan, Hawking et al are idiots and stretcher case retards, whose impetus is the dumbing down of mankind, who remain the scientific equivalent of politicians and journalists, blind to hard evidence 911 was an inside job!

See the Virgo cluster for images of galaxies extending as far as the eye can see, some appear to exist in a swarm around the sub cluster at the core, others are in streamers and wisps of galaxies extending outward, until their images are no more than pin points.

In the 1950's when the spectra of deep field galaxies, obtained by Edwin Hubble with the two hundred inch telescope on Mount Palomar, was subjected to scrutiny, it was found that the absorption lines of all the common elements were shifted toward the red end of the spectrum.

This is called redshift, the furthest ones away attested to by their small image width on the photographic plates, all had greater RS than their closer counterparts whose images subtended a greater angle.

When space based and adaptive optic instruments extended the visual limit even further, vastly more distant edge on spiral galaxies, recognized as a central bulge with two pointy bits extending about twice as far on the same axis, emerged in the same advanced stages of evolution as the MW.

Here RS is approaching twelve which puts the rate of recession well into the super luminal category, which means faster than the speed of light, yet they are goin’ about their own business the same as around here.

Expanding the images further for faint blobs of light which are galaxies ever further away in every direction, and see them as neurons in the brain of God which is meant in no evangelical sense, it just seems the best way to describe it.

M31 the Andromeda Galaxy has blue shift because it is gravitationally bound with other galaxies in the local group, M31 and the Milky Way or home galaxy with Centaurus A and Dwingeloo 1, another member of the local group which lies directly opposite the nucleus of the MW, will expand to become elliptical galaxies and form a sub cluster typically seen in the middle of larger galaxy clusters.

http://i019.radikal.ru/1309/07/f646e17b818a.jpg
NGC 5128 called Centaurus A twenty six million light yrs away, is currently undergoing that process.

Those who cackle on about the age of the universe expressed as a percentage of it’s present age, say redshift indicates the universe is expanding after the explosion of a primal atom, that accordingly could only have been located right where good ol’ Earth is today, the Big Bang hypothesis.

A class of object called a BL Lacerta object has no redshift, and remains a pinpoint of light on even the deepest fields, is thought to be a tunnel shot of the energy beam from the active nucleus of a quasar.

Modern binocular space based and image stabilized telescopes, have identified a rim of matter surrounding some of the BL Lacerta points of light which does exhibit redshift, supporting that hypothesis.

Thus viewing a distant galaxy with a redshift of eight, between here and there is another galaxy with a RS of four, indicating it was speeding toward the more distant place.

So from the more distant galaxy our galaxy the Milky Way would similarly have a RS of eight, so too would the intervening galaxy viewed from the more distant place have a RS of four, indicating it was speeding toward us at a pretty good clip.

It can not be speeding in both directions at once can it now.. when confronted with that the Big Bangers start on about balloons and expanding space, forget about balloons Hubble was a dictator.

The only person other than him who was allowed to look thru the two hundred inch telescope, was a mule skinner named Milton Humason.

Hubble and Milt cooked up the Expanding Universe theory between the two of them, which is just so much hot air .. assume that most spiral galaxies that look the same are roughly the same size, as distance reduces the linear dimension constantly so too does redshift increase in proportion.

A spiral galaxy that is one degree across, will be twice as distant as another that is two degrees across, similarly one that is half of one degree wide will be twice as far as the first, and four times further than the other.

Blue shift is observable in the discs of rotating galaxies, thus the light from a distant galaxy will exhibit mean redshift in proportion to its linear distance, expanding the image further, as rotation brings parts toward us they will be slightly blue shifted back toward the norm.

Similarly as rotation takes objects away, their light will be shifted so slightly even further toward the red part of the spectrum.

The Hubble Space Telescope went into orbit with an incorrectly ground primary mirror, B’s of D’s were invested in building, storing and testing the HST prior to launch, and nobody had checked to see if the primary mirror was going to work.

Where did the money go, spammers will tell you about what a great asset and what a grand piece of hardware it is, it is not it is a piece of junk, who got the HST money, as well and the trillions missing from the Pentagon revealed September 10, 2001.
