Dark energy DOES exist and it's increasingly driving our universe apart, scientists claim Dark energy DOES exist and it's increasingly driving our universe apart, scientists claim By Daily Mail Reporter Updated: 17:14 GMT, 20 May 2011 Dark energy is driving our universe apart at accelerating speeds, according to a five-year survey of 200,000 galaxies, stretching back seven billion years in cosmic time. The study offers new support for the favoured theory of how dark energy works - as a constant force, uniformly affecting the universe and propelling its runaway expansion. Its findings are based on results from Nasa's space-based Galaxy Evolution Explorer and the Anglo-Australian Telescope on Siding Spring Mountain in Australia. Scientists measured the separations between pairs of galaxies and observed that dark energy (represented by purple grid) is a smooth, uniform force that dominates over the effects of gravity (green grid) But they contradict an alternate theory, where gravity, not dark energy, is the force pushing space apart.

The Great Dark Cosmic Side Coincidence The Great Dark Cosmic Side Coincidence [Earthlit Moon: Dorst/Druckmüller] One of the biggest mysteries — and wonders — in the known Universe flies over our heads every day. Or night, to be more precise. Alas, few human beings ever come to realize these questions even exist, much less ponder about them.

Enigma: Black Holes Glow with a Hot Ring of Light Enigma: Black Holes Glow with a Hot Ring of Light Stephen Hawkings great discovery was that the mysterious regions in space we call black holes radiate heat through quantum effects. Hawking has said that "black holes are not really black after all: they glow like a hot body, and the smaller they are, the more they glow." Hawking's famous theory says that the temperature of a black hole varies inversely to its mass.
Could the Universe Be A Giant Quantum Computer? MIT scientist Seth Lloyd proposes that information is a quantifiable physical value, as much as mass or motion -that any physical system--a river, you, the universe--is a quantum mechanical computer. Lloyd has calculated that "a computer made up of all the energy in the entire known universe (that is, within the visible “horizon” of forty-two billion light-years) can store about 1092 bits of information and can perform 10105 computations/second." The universe itself is a quantum computer, he says, and it has made a mind-boggling 10122 computations since the Big Bang (for that part of the universe within the “horizon”). In Year Million: Science at the Far Edge of Knowledge, Leading and up-and-coming scientists and science writers cast their minds one million years into the future to imagine the fate of the human and/or extraterrestrial galaxy.

10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around.

10 Strange Things About The Universe

Menlo Park, Calif.—The Crab Nebula, one of our best-known and most stable neighbors in the winter sky, is shocking scientists with its propensity for fireworks—gamma-ray flares set off by the most energetic particles ever traced to a specific astronomical object. The discovery, reported today by scientists working with two orbiting telescopes, is leading researchers to rethink their ideas of how cosmic particles are accelerated. "We were dumbfounded," said Roger Blandford, who directs the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University. "It's an emblematic object," he said. The Crab Nebula, also known as M1, was the first astronomical object catalogued in 1771 by Charles Messier.

Cambridge University astronomers have discovered the 'missing link' in the evolution of the universe following the Big Bang, it was claimed today. For years scientists have known nothing about the 'dark ages' of space - a period between the Big Bang 13.7billion years ago and the creation of the first stars. But newly captured light emitted from a massive black hole has allowed scientists to peer into this unknown portion of the history of the universe. Astronomers discovered remnants of the first stars and evidence of the aftermath of an exploding star, which was a staggering 25 times larger than the sun. Professor Max Pettini, of Cambridge's Institute of Astronomy, believes the discovery of these gases could help reveal the origins of the universe. "We have effectively been able to peer into the Dark Ages using the light emitted from a quasar.

Observations of cosmic microwaves from 380,000 years after the big bang have been essential to modern cosmology, but cosmic neutrinos should carry information on the state of the universe when it was less than a second old.

An Ancient Subatomic Signature Extends Across the Universe: Relic Particles 10 Billion Light-Years in Length Discovered An ancient subatomic signature extends across the universe. It seems that some subatomic particles, invisible and untouchable effects of the very creation of reality, might exist simultaneously across all of space. "Relic" neutrinos, like the relic photons that make up the cosmic microwave background, are leftovers from the hot, dense early universe that prevailed 13.7 billion years ago. But over the lifetime of the cosmos, these relic neutrinos have been stretched out by the expansion of the universe, enlarging the range in which each neutrino can exist. Of course there's a little bit of physics involved when you talk about particles pouring out of the beginning of time. Neutrinos are tiny, almost undetectable neutral particles which stream through pretty much everything, ever.

Scientists glimpse 'dark flow' lurking beyond the edge of the universe There are already two giant cosmic mysteries, sources of hard-to-account for anti-gravity and gravity, called dark energy and dark matter, respectively, which are ubiquitous in the universe. In honour of this, and because the flow cannot be accounted for by the observed distribution of matter in the universe, the Nasa team that found the cosmic drift calls it "dark flow". The find was made using data from Nasa's Wilkinson Microwave Anisotropy Probe (WMAP), which maps out changes (anisotropy) in the microwave (heat) radiation left over from the Big Bang 13.7 billion years ago, when the universe was born.

Is the Universe Actually Made of Math? | Math You’re talking about the way the observer appears to affect the measurement of what’s being observed. Right. There is this beautiful mathematical equation in quantum theory called the Schrödinger equation. It uses something called the wave function to describe the system you are studying—an atom, an electron, whatever—and all the possible ways that system can evolve.

Novikov self-consistency principle

The Novikov self-consistency principle, also known as the Novikov self-consistency conjecture, is a principle developed by Russian physicist Igor Dmitriyevich Novikov in the mid-1980s to solve the problem of paradoxes in time travel, which is theoretically permitted in certain solutions of general relativity (solutions containing what are known as closed timelike curves). The principle asserts that if an event exists that would give rise to a paradox, or to any "change" to the past whatsoever, then the probability of that event is zero. It would thus be impossible to create time paradoxes. History of the principle[edit]
Wheeler–Feynman absorber theory The Wheeler–Feynman absorber theory (also called the Wheeler–Feynman time-symmetric theory) is an interpretation of electrodynamics derived from the assumption that the solutions of the electromagnetic field equations must be invariant under time-reversal symmetry, as are the field equations themselves. Indeed, there is no apparent reason for the time-reversal symmetry breaking which singles out a preferential time direction and thus makes a distinction between past and future. A time-reversal invariant theory is more logical and elegant. Another key principle, resulting from this interpretation and reminiscent of Mach's principle due to Tetrode, is that elementary particles are not self-interacting. This immediately removes the problem of self-energies.

Comoving distance Comoving coordinates[edit] While general relativity allows one to formulate the laws of physics using arbitrary coordinates, some coordinate choices are more natural (easier to work with). Comoving coordinates are an example of such a natural coordinate choice. They assign constant spatial coordinate values to observers who perceive the universe as isotropic. Such observers are called "comoving" observers because they move along with the Hubble flow. A comoving observer is the only observer that will perceive the universe, including the cosmic microwave background radiation, to be isotropic.
