Multiverse Controversy Heats Up over Gravitational Waves

The multiverse is one of the most divisive topics in physics, and it just became more so. The major announcement last week of evidence for primordial ripples in spacetime has bolstered a cosmological theory called inflation, and with it, some say, the idea that our universe is one of many universes floating like bubbles in a glass of champagne. Critics of the multiverse hypothesis claim that the idea is untestable—barely even science. But with evidence for inflation theory building up, the multiverse debate is coming to a head.

Will We Ever… Travel in Wormholes?

Will We Ever… Travel in Wormholes?

The universe is huge. Travelling at light speed to the nearest star would take more than four years. Venturing to the other side of the galaxy? More than 100,000 years. So what’s an intrepid space traveler to do? One option is a cosmic shortcut called a wormhole, a tunnel through the fabric of space and time that can connect far-flung corners of the universe. Hopping through a wormhole would be incredibly difficult, say scientists, but they have yet to rule it out. So, what would it take in reality, and what exactly is stopping us now?

We May Already Know How We Will Cure Death—But Should We?

We May Already Know How We Will Cure Death—But Should We?

The quest for humans to live forever is elegantly laid out in “The Immortalists,” a new documentary making its away around the film festival circuit. The Immortalists follows the triumphs and tragedies of three years in the lives of William H. Andrews and Aubrey de Grey, two men who prove just as interesting as the work they’re doing. The Immortalists is really a film about death, not life, which is what makes it so fascinating. The goal of Andrews and de Grey is not merely to extend life, but to actually reverse the aging process. “Once we are really truly repairing things as fast as they go wrong, game over,” de Grey says in the film. “We will have the ability to live indefinitely.”

Newly Discovered Dwarf Planet Hints At a Hidden Super Earth In Dim Reaches of Solar System

Discovery of an icy “dwarf” world beyond Pluto hints that a much bigger planet may hide even farther out in the dim reaches of the solar system, astronomers suggested on Wednesday.

MIT Engineers Design Hybrid Living/Nonliving Materials

MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving materials, such as gold nanoparticles and quantum dots. These “living materials” combine the advantages of live cells — which respond to their environment, produce complex biological molecules, and span multiple length scales — with the benefits of nonliving materials, which add functions such as conducting electricity or emitting light.

Michio Kaku on the Evolution of Intelligence

Dr. Michio Kaku explains the evolution of human intelligence. How did we become intelligent? What separated us from the animals? Well there are basically three ingredients — at least three that help to propel us to become intelligent. One is the opposable thumb…

Our Universe May Exist in a Multiverse, Cosmic Inflation Discovery Suggests

Our Universe May Exist in a Multiverse, Cosmic Inflation Discovery Suggests

The first direct evidence of cosmic inflation — a period of rapid expansion that occurred a fraction of a second after the Big Bang — also supports the idea that our universe is just one of many out there, some researchers say. This theory posits that, when the universe grew exponentially in the first tiny fraction of a second after the Big Bang, some parts of space-time expanded more quickly than others. This could have created “bubbles” of space-time that then developed into other universes.

Cosmic Inflation & Gravitational Waves: Complete Coverage of Major Discovery – the ‘Smoking Gun’ for Universe’s Incredible Big Bang Expansion

On March 17, 2014 scientists announced the first direct detection of the cosmic inflation behind the rapid expansion of the universe just a tiny fraction of a second after the Big Bang 13.8 billion years ago. A key piece of the discovery is the evidence of gravitational waves, a long-sought cosmic phenomenon that has eluded astronomers until now.

The Science of ‘Paying It Forward’

In recent years, social scientists have conducted experiments demonstrating that the effect of a single act of kindness can in fact ripple through a social network, setting off chains of generosity that reach far beyond the original act. But whether it is enough to merely witness a generous act, rather than actually benefit from one, has been an open question.

Einstein’s Lost Theory Describes a Universe Without a Big Bang

In 1917, a year after Albert Einstein’s general theory of relativity was published—but still two years before he would become the international celebrity we know—Einstein chose to tackle the entire universe. His calculations told him that the universe could not stay static: it had to either expand or contract. Einstein chose to ignore what his mathematics was telling him. The story of Einstein’s solution to this problem—the maligned “cosmological constant” (also called lambda)—is well known in the history of science. But this story, it turns out, has a different ending than everyone thought: Einstein late in life returned to considering his disgraced lambda. And his conversion foretold lambda’s use in an unexpected new setting, with immense relevance to a key conundrum in modern physics and cosmology: dark energy.

The Baloney Detection Kit: Carl Sagan’s Rules for Bullshit-Busting and Critical Thinking

Through their training, scientists are equipped with what Carl Sagan calls a “baloney detection kit” — a set of cognitive tools and techniques that fortify the mind against penetration by falsehoods. The kit is brought out as a matter of course whenever new ideas are offered for consideration. But the kit, Sagan argues, isn’t merely a tool of science — rather, it contains invaluable tools of healthy skepticism that apply just as elegantly, and just as necessarily, to everyday life. By adopting the kit, we can all shield ourselves against clueless guile and deliberate manipulation. Sagan shares nine of these

Stonehenge: Built For Music?

The prehistoric monument Stonehenge may have been built as a giant xylophone, researchers have claimed. The Royal College of Art spent months tapping more than 1,000 types of rock to study the monument’s musical qualities. Most rocks produced a “dull thud” while the bluestones, which formed the earliest stone circle, were found to “sing” when struck. The rocks made a range of metallic sounds like bells, gongs and tin drums, the study confirmed. Read more: Rock ‘n’ roll: Stonehenge may have been a giant xylophone

Scientific Research Suggests We Unconsciously React to Events Up to 10 Seconds Before They Happen

Scientific Research Suggests We Unconsciously React to Events Up to 10 Seconds Before They Happen

Can your brain detect events before they even occur? That was the stunning conclusion of a 2012 meta-analysis of experiments from seven independent laboratories over the last 35 years, which found that the human body “can apparently detect randomly delivered
stimuli occurring 1-10 seconds in the future” (Mossbridge, Tressoldi, & Utts, 2012). In the studies, physiological readings were taken as participants were subjected to unpredictable events designed to activate the sympathetic nervous system (for example, showing provocative imagery) as well as ‘neutral events’ that did not activate the nervous system. These readings showed that the nervous system aligned with the nature of the event (activated/not activated) – and what’s more, the magnitude of the pre-event response corresponded with the magnitude of the post-event response.
