Most cosmologists will not admit it publicly, but perhaps over a beer they would tell you what is happening. Observations over the last 50 years, culminating with the Planck satellite results set modern science on a counter revolution leading closer to ideas formed 500 years ago. Today’s cosmology is based on two broad principles: The Copernican Principle (we are not in a special place in the universe) and the Cosmological Principle (The Copernican Principle, plus isotropy- the view from anywhere in the universe looks about the same). Starting with early studies of the cosmic microwave background (CMB), and in recent years culminating with results from the COBE then the WMAP satellites, scientists were faced with a signal at the largest scales of the universe- a signal that pointed right back at us, indicating that we are in a special place in the universe.
Without getting overly technical, the Copernican and cosmological principles require that any variation in the radiation from the CMB be more or less randomly distributed throughout the universe, especially on large scales. Results from the WMAP satellite (early 2000s) indicated that when looking at large scales of the universe, the noise could be partitioned into “hot” and “cold” sections, and this partitioning is aligned with our ecliptic plane and equinoxes. This partitioning and alignment resulted in an axis through the universe, which scientists dubbed “the axis of evil”, because of the damage it does to their theories. This axis passes right through our tiny portion of the universe. Laurence Krauss commented in 2005:
“ But when you look at [the cosmic microwave background] map, you also see that the structure that is observed, is in fact, in a weird way, correlated with the plane of the earth around the sun. Is this Copernicus coming back to haunt us? That’s crazy. We’re looking out at the whole universe. There’s no way there should be a correlation of structure with our motion of the earth around the sun — the plane of the earth around the sun — the ecliptic. That would say we are truly the center of the universe.”
Most scientists brushed the observation off as a fluke of some type, and many theories were created to explain it away. Many awaited the Planck mission. The Planck satellite was looked upon as a referee for these unexpected (and unwelcome) results. The Planck satellite used different sensor technology, and an improved scanning pattern to map the CMB. In March 2013, Planck reported back, and in fact verified the presence of the signal in even higher definition than before!
Rong-Gen Cai and Zhong-Liang Tuo at the Key Laboratory of Frontiers in Theoretical Physics at the Chinese Academy of Sciences in Beijing have re-examined the data from 557 supernovas throughout the Universe and recrunched the numbers.
Today, they confirm that the preferred axis is real. According to their calculations, the direction of greatest acceleration is in the constellation of Vulpecula in the Northern hemisphere. That’s consistent with other analyses and also with other evidence such as other data showing a preferred axis in the cosmic microwave background.
Cosmic Deflation: Doubts Raised Over Blockbuster Big Bang Study
A major new study claimed to find direct evidence of the Big Bang and the theory of cosmic inflation. But now scientists aren't so sure. It was just weeks ago that astronomers announced a major, double-barreled discovery: using a super-sensitive microwave telescope known as BICEP2, they had seen evidence of gravity waves that roiled the cosmos before it was a billionth of a trillionth of a second old. That was part one; part two was that the observed gravity waves strongly confirmed the theory of cosmic inflation—that the entire universe went into warp overdrive, expanding faster than the speed of light for the tiniest fraction of a second.
It was Nobel-level work, no doubt about it—provided it was true. But from the moment it was announced at a high-profile press conference, outside scientists had their doubts. There was reason to suspect, they said, that the Harvard-led team might actually have detected nothing more exciting than interstellar dust in the Milky Way. And now a paper expected to go online today, written by Raphael Flauger, of New York University and the Institute for Advanced Study in Princeton, puts those doubts in writing.
The signal may still be from the dawn of time, he writes. But it might equally well be what Princeton University astrophysicist David Spergel calls “schmutz” (in precisely that language: it’s what the Urban Dictionary defines as the Yiddish term “used by Jewish mothers to identify that you’ve got some kind of crap on your face.”) “At this point,” says Spergel, “I’m convinced that they haven’t made a discovery.”
An Indian theoretical physicist who questioned the existence of black holes and thereby challenged Stephen Hawking of Britain at last feels vindicated. But he is sad.
Abhas Mitra, at the Bhabha Atomic Research Centre (BARC) in Mumbai, was perhaps the first and the only scientist who had the guts to openly challenge Hawking of Cambridge University who is regarded by many as the modern-day Einstein.
For over 30 years Hawking and his followers were perpetuating the theory that black holes -- resulting from gravitational collapse of massive stars -- destroy everything that falls into them preventing even light or information to escape.
Mitra, four years ago, in a controversial paper in the reputed journal, Foundations of Physics Letters, showed that Hawking's theory was flawed. He proved black holes couldn't exist because their formation and existence flouted Einstein's general theory of relativity. Except a handful, the majority of mainstream scientists
dismissed Mitra's conclusions even though, till now, no scientist has contradicted him in writing. Mitra invited several notable black hole theorists including Hawking and Jayant Narlikar of India to criticise his work but no one replied.
Naturally, Mitra now feels vindicated following Hawking's own admission two weeks ago at a conference in Dublin, Ireland, that there isn't a black hole "in the absolute sense."
In essence, Hawking's "new" black holes never quite become the kind that gobble up everything. Instead, they keep emitting radiation for a long time -- exactly what Mitra showed in his paper.
Hawking's about-turn has vindicated Mitra. But, in retrospect, he feels sad about the treatment he got at home while trying to take on Hawking all by himself.
Too "embarrassed" to be associated with a man who challenged Hawking, even Mitra's close colleagues avoided him and he became an outcast. To add insult to injury, BARC authorities removed Mitra from the theoretical physics division on the excuse that this division was meant only for those doing "strategic research."
Though Mitra stresses that the `Black Hole’’ solutions are correct, his contention is that Black Hole masses, arising from relevant integration constants, are actually zero. His peer reviewed paper published in Journal of Mathematical Physics of the American Institute of Physics supports this contention by showing that Schwarzschild black holes have M = 0.[27] If so, (i) The so-called massive Black Hole Candidates (BHCs) must be quasi-black holes rather than exact black holes and (ii) During preceding gravitational collapse, entire mass energy and angular momentum of the collapsing objects must be radiated away before formation of exact mathematical black holes. And since the formation of a mathematical zero mass black hole requires infinite proper time, continued gravitational collapse becomes eternal, and the so-called black hole candidates must be Eternally Collapsing Objects (ECO).[28][29][30][31] Mitra’s peer reviewed papers describe why continued physical gravitational collapse should lead to formation of ECOs rather than true black holes, and the mathematical ``black hole’’ states can be achieved only asymptotically.[32][33][34][35][36] An ECO is essentially a quasi-stable ultra-compact ball of fire (plasma) which is so hot due to preceding gravitational contraction that its outward radiation pressure balances its inward pull of gravity. Some American astrophysicists[37][38][39][40][41] claimed to have verified this prediction that astrophysical Black Hole Candidates are actually ECOs rather than true mathematical black holes. The corresponding Harvard University Press Release[42] acknowledges Mitra's original contribution in this context.
Counterfactual quantum cryptography, based on the idea of interaction-free measurement, allows Bob to securely transmit information to Alice without the physical transmission of a particle. From local causality, we argue that the fact of his communication entails the reality of the quantum wave packet she transmits to him. On the other hand, the travel was not physical, because were it, then a detection necessarily follows, which does not happen in the counterfactual communication. On this basis, we argue that the particle's wave function is real, but nonphysical. In the classical world, the reality and physicality of objects coincide, whereas for quantum phenomena, the former is strictly weaker. Since classical cryptography is insecure, the security of quantum counterfactual cryptography implies the nonphysical reality of the wave function.
Cosmology is in Crisis and this is because many people in Cosmology try to fit data into their preferred theories or they just ignore any evidence that contradicts their preferred theories.
Efforts to understand time below the Planck scale have led to an exceedingly strange juncture in physics. The problem, in brief, is that time may not exist at the most fundamental level of physical reality. If so, then what is time? And why is it so obviously and tyrannically omnipresent in our own experience? “The meaning of time has become terribly problematic in contemporary physics,” says Simon Saunders, a philosopher of physics at the University of Oxford. “The situation is so uncomfortable that by far the best thing to do is declare oneself an agnostic.”
The trouble with time started a century ago, when Einstein’s special and general theories of relativity demolished the idea of time as a universal constant. One consequence is that the past, present, and future are not absolutes. Einstein’s theories also opened a rift in physics because the rules of general relativity (which describe gravity and the large-scale structure of the cosmos) seem incompatible with those of quantum physics (which govern the realm of the tiny). Some four decades ago, the renowned physicist John Wheeler, then at Princeton, and the late Bryce DeWitt, then at the University of North Carolina, developed an extraordinary equation that provides a possible framework for unifying relativity and quantum mechanics. But the Wheeler-DeWitt equation has always been controversial, in part because it adds yet another, even more baffling twist to our understanding of time.
“One finds that time just disappears from the Wheeler-DeWitt equation,” says Carlo Rovelli, a physicist at the University of the Mediterranean in Marseille, France. “It is an issue that many theorists have puzzled about. It may be that the best way to think about quantum reality is to give up the notion of time—that the fundamental description of the universe must be timeless.”
