Warp Drive More Possible Than Thought, Scientists Say

Warp Drive More Possible Than Thought, Scientists Say
HOUSTON — A warp drive to achieve faster-than-light travel — a concept popularized in television's Star Trek — may not be as unrealistic as once thought, scientists say. A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light. A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre; however, subsequent calculations found that such a device would require prohibitive amounts of energy. Now physicists say that adjustments can be made to the proposed warp drive that would enable it to run on significantly less energy, potentially bringing the idea back from the realm of science fiction into science. "There is hope," Harold "Sonny" White of NASA's Johnson Space Center said here Friday (Sept. 14) at the 100 Year Starship Symposium, a meeting to discuss the challenges of interstellar spaceflight.

Egyptian Teenager Creates Next-Generation Quantum Space Propulsion System An Egyptain teenager has patented a next-generation propulsion system that could send spacecraft to other solar systems—without using a single drop of fuel. While it is not quite warp-drive technology, young physicist Aisha Mustafa’s system is based on quantum physics and could see mankind boldly go where no man has gone before. The 19-year-old is further proof that young minds produce fresh new ideas. Her propulsion system gets rid of traditional rocket boosters in favor of a more futuristic concept. For those of you who aren’t up to scratch on quantum physics, Mustafa’s idea works on the principle that space is not a vacuum. Instead, it is filled with a roiling sea of particles and anti-matter particles that are created and then destroy themselves in a blink of an eye.

NASA: Warp drive is 'plausible and worth further investigation' Warp drive, a staple of science-fiction, has just been deemed "plausible and worth further investigation" by the smart and apparently not crazy people over at NASA. And by way of further investigation, they've gone and started trying to create warp bubbles in the lab. The principle of warp drive is really fairly simple. Nothing that exists in space is supposed to be able to go faster than the speed of light, right? Right.

Dead stars 'to guide spacecraft' 30 March 2012Last updated at 12:28 ET By Jonathan Amos Science correspondent, BBC News, Manchester Spacecraft could one day navigate through the cosmos using a particular type of dead star as a kind of GPS. German scientists are developing a technique that allows for very precise positioning anywhere in space by picking up X-ray signals from pulsars. Why Nikola Tesla was the greatest geek who ever lived Additional notes from the author: If you want to learn more about Tesla, I highly recommend reading Tesla: Man Out of Time Also, this Badass of the week by Ben Thompson is what originally inspired me to write a comic about Tesla. Ben's also got a book out which is packed full of awesome. There's an old movie from the 80s on Netflix Instant Queue right now about Tesla: The Secret of Nikola Tesla. It's corny and full of bad acting, but it paints a fairly accurate depiction of his life. The drunk history of Tesla is quite awesome, too.

We're More than Stardust — We're Made of the Big Bang Itself Transcript Anna Frebel: The work of stellar archaeology really goes to the heart of the "we are stardust" and "we are children of the stars" statement. You’ve probably heard it all but what does it actually mean? UFO Cases Directory: All Cases: Sorted by Oldest First 329 BC: Alexander the Great records two great 'flying shields' 329 BC - Central Asia, Alexander the Great records two great silver shields, spitting fire around the rims in the sky that dived repeatedly at his army as they were attempting a river crossing. The action so panicked his elephants, horses, and men they had to abandon the river crossing until the following day.

Alcubierre drive Two-dimensional visualization of the Alcubierre drive, showing the opposing regions of expanding and contracting spacetime that displace the central region. The Alcubierre drive or Alcubierre metric (referring to metric tensor) is a speculative idea based on a solution of Einstein's field equations in general relativity as proposed by theoretical physicist Miguel Alcubierre, by which a spacecraft could achieve faster-than-light travel if a configurable energy-density field lower than that of vacuum (i.e. negative mass) could be created. Rather than exceeding the speed of light within its local frame of reference, a spacecraft would traverse distances by contracting space in front of it and expanding space behind it, resulting in effective faster-than-light travel.

Wormhole Construction: Proceed with Caution Ronnie Chen/Hampton University, from a ThinkQuest project Spaceships on Star Trek: Deep Space 9 regularly take a shortcut between distant parts of the Universe by traveling through a wormhole, a kind of spacetime tunnel. Although Einstein’s General Relativity theory allows wormholes to exist, physicists have been trying for decades to construct them mathematically without breaking any other laws of physics. Most researchers agree that wormholes require “exotic matter”–stuff that is repelled by gravity, rather than attracted–but some have claimed ways around that problem.

The Elements by Theodore Gray Praise for The Elements The printing quality of this book is truly extraordinary. The pictures leap out from a deep black background, just as brightly as they do on the computer screen. (And the metalized cover is pretty nifty!) If you don't believe me how packed this book is with elements, take a look at this complete catalog of the pages in the book. If you love science, or art, or life, or anything really, you'll love this book. Monkey teeth hint at a miraculous marine migration to North America Scientists have long thought that monkeys first ventured from South America into North America no earlier than about 4 million years ago, when the two continents merged. But seven teeth unearthed in Panama may change that story. These monkey teeth were discovered encased in 21-million-year-old rocks. This suggests that the primates accomplished the impossible: they crossed the more than 100 miles of ocean that separated South America from North America at the time. These prehistoric monkeys, which probably looked like today's capuchin monkeys, are the only mammals known to cross this watery boundary so early, says Jonathan Bloch. Dr.
