Ein Universum aus dem Nichts – der Beweis gegen Gott?

Mit „Ein Universum aus dem Nichts“ fasst der Kosmologe Lawrence Krauss den Stand der momentanen Schöpfungstheorie zusammen – und provoziert nicht nur Kreationisten. Laut Krauss machen die Ergebnisse einen Gottglauben obsolet.

Zuerst leuchtete ein gleißender Funke auf. Aus dem subatomaren Glutball erwuchs in Sekundenbruchteilen ein Gebilde von der Größe einer Pampelmuse, das danach langsam weiter expandierte. Unser All war geboren — hervorgegangen aus dem Feuersturm des Urknalls. Was aber löste diese Urexplosion aus? Stand am Weltenbeginn das Walten eines Gottes, wie es die Schöpfungsgeschichten der Weltreligionen bekunden? Oder brachten natürliche physikalische Prozesse das Universum hervor?

Are We Living in a Simulated Universe?

„The fact that heavy elements were plentiful only 5 billion years after the big bang is a very good sign about the possibility of alien-life evolving in the very earlier universe. But of course that then leads to the annoying and now cliche Fermi paradoxical question: If alien life had several billion years to get started earlier than we might have initially expected, then where the heck are they? Consider this: If a hyper intelligent civilization arose when the universe was only 5 billion years old, then it should have had time to effectively colonize every galaxy in the universe, simply by sending out replicating-machines and probes to every visible galaxy at once, simultaneously. And of course once each probe reached the target galaxy, it would only take a few hundred thousands years (or perhaps a couple of million years at most) to establish replicating probes in every star system of that galaxy. So really once life reaches hyper intelligence, then it doesn’t take very long to colonize not only a single galaxy, but the entire universe. Thus there really should be aliens amongst us.

Spuren des Urknalls: „Planck“-Daten geben Kosmologen Rätsel auf

Das Universum ist etwas älter und etwas anders zusammengesetzt als bisher vermutet – doch abgesehen davon scheinen die neuen Ergebnisse des „Planck“-Teleskops kosmologische Standardmodelle zu bestätigen. Wenn da nicht einige unerklärliche Ausnahmen wären.

Higgs-Boson-Erkenntnisse: Physiker halten Universum für instabil

Ist der Fund des Higgs-Bosons eine schlechte Nachricht für unser Universum? Physik-Theoretiker glauben, dass die Masse des Teilchens in einem Bereich liegt, der dem Kosmos ein Verfallsdatum gibt. Ein baldiges Ende ist jedoch unwahrscheinlich.

„Every Galaxy has Counterparts in Other Universes“

“The quantum theory of parallel universes is not the problem, it is the solution. It is not some troublesome, optional interpretation emerging from arcane theoretical considerations,“ says David Deutsch. „It is the explanation, the only one that is tenable, of a remarkable and counter-intuitive reality. Everything in our universe — including you and me, every atom and every galaxy — has counterparts in these other universes.“

Legendary Oxford physicist David Deutsch is best known for his contributions to quantum physics, quantum computing, and a leading proponent of the multiverse (or „many worlds“) interpretation of quantum theory — the astounding idea that our universe is constantly spawning countless numbers of worlds.

„Gravity Doesn’t Exist“ –Is this Fundamental Phenomenon of the Universe an Illusion?

Could both gravity and the Big Bang be an illusion? In January 2010, Erik Verlinde, professor of Theoretical Physics and world-renowned string theorist, caused a worldwide stir with the publication of On the Origin of Gravity and the Laws of Newton, in which he challenged commonly held perceptions on gravity, going so far as to state ‘for me gravity doesn’t exist’. If he is proved correct, the consequences for our understanding of the universe and its origins in a Big Bang will be far-reaching.

„Everyone who is working on theoretical physics is trying to improve on Einstein,“ says Robbert Dijkgraaf, UvA University Professor and current director of the Institute for Advanced Study in Princeton (where scientists including Turing, Oppenheimer and Einstein have worked) In my opinion, Erik Verlinde has found an important key for the next step forward.“

Verlinde, who received the Spinoza prize (the Dutch Nobel Prize) from the Netherlands Organisation for Science, is famous for developing this new theory, or idea, on gravity in which he says that gravity is an illusion. „Gravity is not an illusion in the sense that we know that things fall,“ says Verline.“ Most people, certainly in physics, think we can describe gravity perfectly adequately using Einstein’s General Relativity. But it now seems that we can also start from a microscopic formulation where there is no gravity to begin with, but you can derive it. This is called ‘emergence’.“

New Theory of Dark Matter & Energy Alters Einstein’s View of Spacetime

A pair of mathematicians — one from Indiana University and the other from Sichuan University in China — have proposed a unified theory of dark matter and dark energy that alters Einstein’s equations describing the fundamentals of gravity.

„In a nutshell, we believe that new gravity theory will change our view on energy, gravitational interactions, and the structure and formation of our universe,“ said Shouhong Wang, a professor of mathematics at Indiana University.

Wang and Tian Ma, a professor at Sichuan University, suggest the law of energy and momentum conservationin spacetime is valid only when normal matter, dark matter and dark energy are all taken into account. For normal matter alone, energy and momentum are no longer conserved, they argue.

While still employing the metric of curved spacetime that Einstein used in his field equations, the researchers argue the presence of dark matter and dark energy — which scientists believe accounts for at least 95 percent of the universe — requires a new set of gravitational field equations that take into account a new type of energy caused by the non-uniform distribution of matter in the universe. This new energy can be both positive and negative, and the total over spacetime is conserved, Wang said.

It is curved spacetime, along with a new scalar potential field representing the new energy density, and the interactions between the two that form the foundation for the new gravitational field equations.

„The Universe is Timeless“ –A Radical Theory of Spacetime

Scientists at the Scientific Research Centre Bistra in Ptuj, Slovenia, have theorized that the
Newtonian idea of time as an absolute quantity that flows on its own, along with the idea that time is the fourth dimension of spacetime, are incorrect. They propose to replace these concepts of time with a view that corresponds more accurately to the physical world: time as a measure of the numerical order of change.

This view doesn’t mean that time does not exist, but that time has more to do with space than with the idea of an absolute time. So while 4D spacetime is usually considered to consist of three dimensions of space and one dimension of time, the researchers’ view suggests that it’s more correct to imagine spacetime as four dimensions of space. In other words, as they say, the Universe is “timeless.”

„Big Bang or the Big Bounce?“ –New Science Points to a Continuum

The big bang may not have been the beginning of the universe, but merely the beginning of one of an infinite series of universes. Two fundamental concepts in physics, both of which explain the nature of the Universe in many ways, have been difficult to reconcile with each other. European researchers have developed a mathematical approach to do so that has the potential to explain what came before the Big Bang.

The big bang singularity –the single point from which the entire universe is supposed to have sprung– is the major sticking point in the big bang theory; the calculations just can’t account for such a singularity. Without evidence associated with the earliest instant of the expansion, the Big Bang theory does not provide any explanation for such an initial condition.

„Some Black Holes Existed Prior to the Big Bang“

Cosmologists have begun to think seriously about processes that occurred before the Big Bang. Alan Coley from Canada’s Dalhousie University and Bernard Carr from Queen Mary University in London, have theorized that some so-called primordial black holes might have been created in the Big Crunch that came before the Big Bang, which supports the theory that the Big Bang was not a single event, but one that occurs over and over again as the Universe crunches down to a single point, then blows up again.

In some circumstances, they say, black holes of a certain mass could avoid this fate and survive the crunch as separate entities. The masses for which this is possible range from a few hundred million kilograms to about the mass of our Sun.

Higgs-Boson: Alles nur Theorie?

MEYRIN. (hpd) Zum Nachweis des Higgs-Bosons überschlagen sich zurzeit in der Presse die Meldungen über den offenbar gelungenen Nachweis des so genannten „Gottesteilchens“. Ein Physiker würde nie auf die Idee kommen, eine solch unsinnige Bezeichnung zu kreieren. Man könnte sie vielleicht so interpretieren: Es ist das Teilchen, das Gott als Schöpfer des Universums endgültig und restlos überflüssig macht.

„90% of Distant Galaxies in Universe Unseen“ –European Space Agency Astronomers

The European Space Agency’s Herschel space telescope has discovered that previously unseen distant galaxies are responsible for a cosmic fog of infrared radiation. The galaxies are some of the faintest and furthest objects seen by Herschel, and open a new window on the birth of stars in the early Universe. Astronomers estimate that their are billions and billions of galaxies in the observable universe (as well as some seven trillion dwarf galaxies) .

Here’s how astronomers breakout  the visible universe within 14 billion light years:

Superclusters in the visible universe = 10 million

Galaxy groups in the visible universe = 25 billion

Large galaxies in the visible universe = 350 billion

Dwarf galaxies in the visible universe = 7 trillion

Stars in the visible universe = 30 billion trillion  (3×10²²)

Astronomers realize that they may have underestimated the number of galaxies in some parts of the universe by as much as 90 percent, according to Matthew Hayes of the University of Geneva’s Observatory, who led the investigation using the world’s most advanced optical instrument — Europe’s Very Large Telescope (VLT) in Chile, which has four 8.2-meter (26.65-feet) behemoths. They turned two of the giants towards a well-studied area of deep space called the GOODS-South field.

Lawrence Krauss: Life, the Universe and Nothing

„Our Universe is Merely a Region of an Enormous Universe“

„This new concept is, potentially, as drastic an enlargement of our cosmic perspective as the shift from pre-Copernican ideas to the realization that the Earth is orbiting a typical star on the edge of the Milky Way.“

Sir Martin Rees, physicist, Cambridge University, Astronomer Royal of Britain

Is our universe merely a part of an enormous universe containing diverse regions each with the right amount of the „dark energy“ and each larger than the observed universe, according to  Raphael Bousso, Professor of Theoretical Physics, U of California/Berkeley and Leonard Susskind, Felix Bloch Professor of Physics, Stanford University. The two theorize that information can leak from our causal patch into others, allowing our part of the universe to „decohere“ into one state or another, resulting in the universe that we observe.
