Timeline of the universe | Science Using observatories on the earth and in space, astronomers have been able to study the nature of the cosmos in unprecedented detail. By analysing the motion of distant galaxies, they have discovered that the whole cosmos is expanding under the influence of forces unleashed at its birth in the big bang. Combined with studies of the radiation left over from that primordial explosion, they have found that the universe was born 13.7bn years ago, give or take 200m years. Pinning down the date of creation with such precision is impressive, but scientists have gone much further. 10^-43 seconds Known as the Planck Era, this is the closest that current physics can get to the absolute beginning of time. 10^-35 seconds The so-called Grand Unification Era, at the end of which the superforce begins to break apart into the constituent forces we see today. 10^-32 seconds 10^-11 seconds 10^-6 seconds 200 seconds 300,000 years 200m years 0.5bn - 1bn years 9bn years 9.1bn years
Vacuum energy Vacuum energy is an underlying background energy that exists in space throughout the entire Universe. One contribution to the vacuum energy may be from virtual particles which are thought to be particle pairs that blink into existence and then annihilate in a timespan too short to observe. They are expected to do this everywhere, throughout the Universe. Their behavior is codified in Heisenberg's energy–time uncertainty principle. Still, the exact effect of such fleeting bits of energy is difficult to quantify. The effects of vacuum energy can be experimentally observed in various phenomena such as spontaneous emission, the Casimir effect and the Lamb shift, and are thought to influence the behavior of the Universe on cosmological scales. Origin[edit] Summing over all possible oscillators at all points in space gives an infinite quantity. Additional contributions to the vacuum energy come from spontaneous symmetry breaking in quantum field theory. Implications[edit] [citation needed]
Google, democracy and the truth about internet search | Technology Here’s what you don’t want to do late on a Sunday night. You do not want to type seven letters into Google. That’s all I did. I typed: “a-r-e”. And then “j-e-w-s”. Are Jews evil? Google is search. The sixth is from Yahoo Answers: “Why are Jews so evil?” There’s one result in the 10 that offers a different point of view. I feel like I’ve fallen down a wormhole, entered some parallel universe where black is white, and good is bad. Stories about fake news on Facebook have dominated certain sections of the press for weeks following the American presidential election, but arguably this is even more powerful, more insidious. He came across a similar instance in 2006 when, “If you typed ‘Jew’ in Google, the first result was jewwatch.org. Google is knowledge. Next I type: “a-r-e m-u-s-l-i-m-s”. Jews are evil. A few days later, I talk to Danny Sullivan, the founding editor of SearchEngineLand.com. He’s surprised too. Google isn’t just a search engine, of course. Like a cancer? “Look at that.
Unveiling the Mystics of Sacred Geometry Sacred Geometry, how can I find the words to describe it? The need for us to speak about Sacred Geometry was dire but as usual the need to be thorough delayed it. So a week after googling “Sacred Geometry” and trolling through a lot of esoteric links, my mind is exploding with information. There is so much more to put in, but let me try compiling what I have watched and learnt and hopefully we shall present a decent overview on this subject. Let me start with the basic, what is sacred geometry? These same laws can be applied to produce visual harmony. Sacred geometric ratios applied to music gives it healing powers to harmonize a body that is out of balance. Nature itself has so much Sacred Geometry to display and in the video itself you would have heard, if you are open to it, its everywhere! From the center of a Sunflower Sacred Geometry can be seen all around us, here we can see it in the center of the Sunflower. Leonardo da vinci drew the Vitruvian man based on the work of Vitruvius.
Quantum gravity Quantum gravity (QG) is a field of theoretical physics that seeks to describe the force of gravity according to the principles of quantum mechanics. Although a quantum theory of gravity is needed in order to reconcile general relativity with the principles of quantum mechanics, difficulties arise when one attempts to apply the usual prescriptions of quantum field theory to the force of gravity.[3] From a technical point of view, the problem is that the theory one gets in this way is not renormalizable and therefore cannot be used to make meaningful physical predictions. As a result, theorists have taken up more radical approaches to the problem of quantum gravity, the most popular approaches being string theory and loop quantum gravity.[4] Strictly speaking, the aim of quantum gravity is only to describe the quantum behavior of the gravitational field and should not be confused with the objective of unifying all fundamental interactions into a single mathematical framework.
Twin Peaks Gifs Experiment Install theme How Does Theta Work | Quantum Theta The scientific basis of ThetaHealing® consists of two main categories, quantum and epigenetic: Quantum StuffWe are quantum beings. This simple fact is the beginning of understanding how and why ThetaHealing® works. We are not merely physical beings, made of matter. Scientists proved early in the last century that classical physics — that is, the theory that we are made up of solid sub-atomic particles whose activities can be understood and reliably predicted — is not entirely accurate. An important concept in both the quantum and the ThetaHealing® worlds is the observer effect: the fact that, as proven to surprised scientists in studies, the act of observation itself has a measurable effect on the behavior of sub-atomic particles. One more awesome aspect of quantum change: it is, by definition, fast. Electrons, as you may or may not remember from your high school science classes, orbit around the nucleus of an atom.
String (physics) In physics, a string is a physical object that appears in string theory and related subjects. Unlike elementary particles, which are zero-dimensional or point-like by definition, strings are one-dimensional extended objects. Theories in which the fundamental objects are strings rather than point particles automatically have many properties that are expected to hold in a fundamental theory of physics. Most notably, a theory of strings that evolve and interact according to the rules of quantum mechanics will automatically describe quantum gravity. In string theory, the strings may be open (forming a segment with two endpoints) or closed (forming a loop like a circle) and may have other special properties. In theories of particle physics based on string theory, the characteristic length scale of strings is typically on the order of the Planck length, the scale at which the effects of quantum gravity are believed to become significant. Strings can be either open or closed.
Top 10 Unsolved Mysteries of Science Despite what cable news may tell you, scientists don’t really squabble over if evolution is real (it is) or if the climate is changing faster than can be explained by naturally-occurring phenomena (it is) or if vaccines are regarded as safe and recommended for most children (they are). Sure, there may be fine points within those categories that are debatable, but not to the extent that is commonly described by talking heads on TV. However, that’s not to say that scientists perfectly understand everything about the ways of the Universe. Physicist Brian Cox once said: “I'm comfortable with the unknown—that’s the point of science. There are places out there, billions of places out there, that we know nothing about. So what are some of the top mysteries keeping scientists busy? Why is there more matter than antimatter? According to our current understanding of particle physics, matter and antimatter are equal but opposite. Where is all the lithium? Why do we sleep? How does gravity work?
