22 Articles on Whether Or Not To Search for Extraterrestrial Life. Full Title:Commentaries: Stephen Hawking's Aliens. The Search for Intelligent Extraterrestrial Life. Project Breakthrough Listen Abstract Stephen Hawking and Yuri Milner have launched a $100m search for intelligent alien life beyond solar system; a program focused on listening for radio signals coming from advanced civilizations far beyond the solar system, which, presumably, rely on similar technologies as those of the present civilizations of Earth. The search will be 50 times more sensitive, and cover 10 times more sky, than previous hunts for alien life. According to Stephen Hawking the effort...

Are We Living In A Black Hole? // / Here’s an idea, what if the universe and everything we see around us is actually inside a black hole?Whenever I’m asked this question, what folks typically have in mind is that the universe began as an infinitely dense point, just like the singularity of a black hole, and because of cosmic expansion there’s a limit to how far we can observe, so maybe that’s like the event horizon. While it’s an interesting idea, things aren’t quite so simple.To begin with, the universe did not begin with an explosion from a...

For the past several centuries everyone believed that Mars was the most likely body in our solar system to support life beyond Earth. But, after centuries of telescope observation, decades of spacecraft exploration and several robots exploring its surface the promise of discovering life on Mars remains elusive. Now, scientific attention is being focused on Europa, the fourth largest of Jupiter's 67 confirmed moons. It may be an even better candidate for finding life than Mars. For life to be present the three basic requirements are: 1) liquid water; 2) chemical building blocks; and, 3) a source of energy. Europa...

Physicists have gained new insights into dark energy and the theory of gravitation by analyzing data from the "Planck" satellite mission of the European Space Agency (ESA). Their results demonstrate that the standard model of cosmology remains an excellent description of the universe. Yet when the Planck data is combined with other astronomical observations, several deviations emerge. Further studies must determine whether these anomalies are due to measurement uncertainties or undiscovered physical correlations, which would also challenge Einstein's theory of gravitation. Thus, the analysis of the Planck data gives major impetus for research during future space missions.

Some simple observations about the universe seem to contradict basic physics. Solving these paradoxes could change the way we think about the cosmos Revolutions in science often come from the study of seemingly unresolvable paradoxes. An intense focus on these paradoxes, and their eventual resolution, is a process that has leads to many important breakthroughs. So an interesting exercise is to list the paradoxes associated with current ideas in science. It’s just possible that these paradoxes will lead to the next generation of ideas about the universe. Today, Yurij Baryshev at St Petersburg State University in Russia does just this...

Stardust got in their eyes. In the spring a group of astronomers who go by the name of BICEP announced they had detected ripples in the sky, gravitational waves that were the opening notes of the Big Bang. The finding was heralded as potentially the greatest discovery of the admittedly young century, but some outside astronomers said the group had underestimated the extent to which interstellar dust could have contaminated the results - a possibility that the group conceded in its official report in June. Now a long-awaited report by astronomers using data from the European Space Agency’s Planck satellite...

It is, if you except the powers of human memory, the closest thing we have to a time machine. Scientists have created the first realistic model of the universe, capable of recreating 13 billion years of cosmic evolution. The simulation is called “Illustris,” and it renders the universe as a cube (350 million light-years on each side) with, its creators say, unprecedented resolution: The virtual universe uses 12 billion 3-D “pixels,” or resolution elements, to create its rendering. And that rendering includes both normal matter and dark matter. The rendering, importantly, also includes elliptical and spiral galaxies—bodies that, because of...

'Smoking Gun' Evidence of Inflation? by Jake Hebert, Ph.D. * On March 17, a team of radio astronomers announced they discovered purportedly direct evidence for cosmic inflation—a critical component of the modern Big Bang model. To make this discovery, the researchers used a specialized telescope called BICEPS2 located on the Antarctic plateau.1 Radiation that has its strongest intensity in the microwave portion of the electromagnetic spectrum comes to us from all directions in space. Secular researchers interpret this cosmic microwave background radiation (CMB) as "relic radiation" from a time about 400,000 years after the alleged cosmic explosion. Now, a team...

As if by magic, the stage morphed into a massive cathedral with imposing stained-glass windows and a marriage archway. High Priestesses “Material Girl” Madonna and pure “royalty,” Queen Latifah, then appeared on stage to join in marriage 33 couples of numerous sexual permutations, thereby sealing the new religion’s Oneist creed: all religions and all sexualities are One—to the thunderous applause of the thousands present, and to the approbation of millions of television viewers. The vacuous marriage sacrament of the “Grammys religion” and its further trivialization as an entertainment stunt, only underlines the spiritually empty gospel that Tinsel Town and its...

ID theorists say that information is the foundation of the universe. Others say matter is. Our choice of who to believe will shape our future. First, suppose the materialists are right. If materialism (naturalism) is simply true, because everything comes down to matter in the end, what future might we expect? Stephen Hawking insists in a recent interview that "Science will win." If we take his current non-realist views seriously, science as we have known it is finished and there is nothing to win. That doesn't mean, of course, that everything shuts down. Some projects will continue as if immortal...

This web page is designed to give everyone an idea of what our universe actually looks like. There are nine main maps on this web page, each one approximately ten times the scale of the previous one. The first map shows the nearest stars and then the other maps slowly expand out until we have reached the scale of the entire visible universe. This atlas does a very good job of providing the proper persepctive in demonstrating the vast distances that encompass our known universe. Of course, like most people, you will find yourself being able to maintain focus, losing...

Goodbye Big Bang, hello black hole? A new theory of the universe's creation Enlarge Artist’s conception of the event horizon of a black hole. Credit: Victor de Schwanberg/Science Photo Library Could the famed "Big Bang" theory need a revision? A group of theoretical physicists suppose the birth of the universe could have happened after a four-dimensional star collapsed into a black hole and ejected debris. Before getting into their findings, let's just preface this by saying nobody knows anything for sure. Humans obviously weren't around at the time the universe began. The standard theory is that the universe grew from...

The universe may end in another 10 billion years or sooner if the heaviest of all the known elementary particles, the top quark, is even heavier than previously thought, researchers say. If the top quark is not heavier than experiments currently suggest, then an even stranger fate may await the cosmos: disembodied brains and virtually anything else could one day randomly materialize into existence. The protons and neutrons that make up the nuclei of atoms are made of elementary particles known as quarks. Protons and neutrons are made up of the lightest and most stable flavors of quark: the up...

Original title:Scientists to Discuss Universe's Strange Dense Spot Wednesday: Watch Live You can't watch it live anymore but you can watch the video of the event. This map shows the oldest light in our universe, as detected with the greatest precision yet by the Planck mission. The ancient light, called the cosmic microwave background, was imprinted on the sky when the universe was 370,000 years old. It shows tiny temperature fluctuations that correspond to regions of slightly different densities, representing the seeds of all future structure: the stars and galaxies of today. An odd dense spot in the universe populated...

A fireball that appeared over the Sri Lankan province of Polonnaruwa on December 29, 2012 was a meteorite containing algae fossils, according to a paper published in the Journal of Cosmology. A team of researchers, led by Jamie Wallis of Cardiff University, believes that these fossils provide evidence of cometary panspermia, the hypothesis that life originated in outer space and comets brought it to Earth. Scientists at the Sri Lankan Medical Research Institute in Colombo forwarded 628 stone fragments that allegedly fell from the fireball to Cardiff University, where Wallis' team indentified three as originating from a carbonaceous chondrite. The...

Massive Quasar Cluster Refutes Core Cosmology Principle by Brian Thomas, M.S. * Astronomers recently found a distant collection of quasars. But those quasars shouldn’t exist. And while they certainly appear connected, they’re spread too far across space for standard secular models of the structure and origin of the universe to accommodate. “It is the largest structure ever seen in the entire universe,” according to astrophysicist Roger Clowes from the University of Central Lancashire.1 Clowes led a team of researchers, who published their discovery in The Monthly Notices of the Royal Astronomical Society,2 in analyzing data from the Sloan Digital Sky...

A group of Penn State physicists says the universe we now see could have arisen from a "Big Bounce" rather than a Big Bang. The new work by Penn State, led by professor Abhay Ashtekar, director of the Institute for Gravitation and the Cosmos, proposes ways to apply quantum physics "further back in time than ever before – right back to the beginning," the university says in a release. We have a pretty good idea of the large-scale structures of the universe when it was only a few hundred thousand years old. That comes from studying the fingerprint of the...

Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe. Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full moon. The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble Space Telescope data from 2003 and...
