Here is a news item: The Hubble and Chandra space telescopes have detected a new belch emerging from a black hole located about 800 million light-years away. But they saw a remnant of another belch that occurred 100,000 years earlier. “Black holes are voracious eaters, but it turns out they don’t have very good table manners,” Julie Comerford, from the University of Colorado, Boulder, told the 231st American Astronomical Society meeting in Washington DC. “There are a lot of examples of black holes with single burps emanating out, but we discovered a galaxy with a supermassive black hole that has not one but two burps.” The burp itself consists of a stream of high-energy particles that is kicked back from the black hole.(BBC online news/science)

When man talks about God, happiness or anything else his language is peppered with what is familiar to his world. Blackholes have voracious appetites we say. I can understand it since I have had voracious appetite some times and so long ago when I have had a cast-iron constitution. It has no meaning whatsoever outside the specific context of humans conveying their observations and based on their own experience. Nature of God, Trinity are all concepts which we employ in human language; logic, rhetorics by the same token are artifices to makes one’s arguments sound superior and it does not however means truth has been established. When we read in the Bible and in several passages, God’s blessings are given in conjunction with all living creatures who makes case for his right to cut out all competition?  When the Spirit writes of God’s anger over the old world he writes,”It grieved him at his heart” and he would destroy them as well. From so many examples it is very clear that God’s Providence would see man in a context than singly. Why? Man is a steward (Ge.1:28) and is responsible for their welfare. In salvation also he is a witness and bring others to peace of God which He assures as the portion for the righteous. Noah among the creatures in the ark is but a snapshot of the Millennial Reign on the earth. This being the case  when we see so many species are either extinct or on the endangered list where did man go wrong? His rational mind only makes his world in terms of dollars and cents but he is steadily making his own future in jeopardy. He accepts only ‘here and now’ and not the way God wants him to. His Time sees past future and present as here and now. God knew that there would be a great famine in Israel so he had set Joseph as his instrument and bestowed bumper crop to Egypt so much so they could be helped. Sufferings of Joseph were foreseen and God’s Providence to sustain a nation it was necessary. God also had instilled in him necessary qualities to ride out all injury and humiliation. Besides God sets him as an antitype for Jesus Christ whose death would bring great many to eternal salvation. God sees all events and persons and their roles in 360°. In short God’s ways are mysterious where man’s ways are only based on short term benefits for himself.

Cosmic lunch where stars partake their table manners however clumsy it would seem leave great blessings. ISM for instance. Do not however ask me who says Grace for the occasion.

Classical physics implies that anything falling through the horizon of a black hole can never escape. But Hawking showed that black holes continually emit radiation once quantum effects are taken into account. Unfortunately, for typical astrophysical black holes, the temperature of this radiation is far lower than that of the cosmic microwave background and we have no way of proving it. If a black hole continually emits radiation, it will continually lose mass – eventually evaporating. Hawking realized that this implied a paradox: if a black hole can evaporate, the information about it will be lost forever. This means that even if we could measure the radiation from a black hole we could never figure out it was originally formed. This violates an important rule of quantum mechanics that states information cannot be lost or created.

Determinism implies that the state of the universe at any given time is uniquely determined from its state at any other time. This is how we can trace its evolution both astronomically and mathematically though quantum mechanics.

If a black hole can evaporate and information lost how will determinism work? Black hole physics provides a test for any potential quantum gravity theory. Whatever your theory is, it must explain what happens to the information recording a black hole’s history.

It took two decades for scientists and they have come up with an answer. They suggested that the information stored in a black hole is proportional to its surface area (in two dimensions) rather than its volume (in three dimensions). This could be explained by quantum gravity, where the three dimensions of space could be reconstructed from a two-dimensional world without gravity – much like a hologram. See a problem like quantum gravity can disappear if we make the universe is a hologram: the real action would play out where gravity is zero. In regimes where there are no analytic tests a holographic universe replaces actual proof.

In this context we have Maldacena conjecture and it  reconciles Einstein’s General Theory of Relativity and quantum mechanics.

Shortly afterwards, string theory, the most studied theory of quantum gravity was also shown to be holographic.

Using holography we can describe the evaporation of the black hole in the two-dimensional world without gravity, for which the usual rules of quantum mechanics apply. This process is deterministic, with small imperfections in the radiation encoding the history of the black hole. So holography tells us that information is not lost in black holes, but tracking down the flaw in Hawking’s original arguments has been surprisingly hard.

Which came first? chicken or egg? Maldacena conjecture in this case makes chicken the hologram projection of egg where gravity is zero. Conversely shall we say chicken is the hologram projection of an egg in another time zone?

In a 4-D world of chickens , the eggs are entangled only in a flattened 3-D scaled down version of reality. Both are present.( cf.universe as a hologram)
