Science Fiction No Match For Reality: Lawrence Krauss
2014-02-16 04:54:06

April Flowers for redOrbit.com - Your Universe Online Science fiction borrows from, and sometimes anticipates, the state of the art in scientific progress. This can be seen from warp drives to hyperspace, and has resulted in the perception that science and science fiction have a causal relationship. People assume that science finds direction from and fulfills the science fantasy laid out before it. According to Lawrence Krauss, a Foundation professor in the School of Space and Earth...

John P. Millis, PhD for redOrbit.com - Your Universe Online For the better part of two decades, the greatest fundamental question facing physics and cosmology has been, quite simply, what is dark energy? Detailed observations of galaxies in our Universe reveal the expansion of the Universe is accelerating. Even after accounting for all of the normal matter, radiation, and even the theorized dark matter out there, there still simply isn't enough "stuff" to explain the dynamics of the...

Before firing up the dilithium crystals in your warp drive, you should know what you are getting into, said Lawrence Krauss, ASU Foundation Professor at Arizona State University. When applied to the known laws of physics, some features of Star Trek — the endearing science fiction franchise that hooked millions of viewers on the possibility of intergalactic space travel — don't always hold up. "For example, the transporter, is, alas, impossible, which is a real shame because I...

Advancing into the next frontier in astrophysics and cosmology depends on our ability to detect the presence of a particular type of wave in space, a primordial gravitational wave. Much like ripples moving across a pond, these waves stretch the fabric of space itself as they pass by. If detected, these weak and elusive waves could provide an unprecedented view of the earliest moments of our universe. In an article appearing in the May 21 issue of Science, Arizona State University theoretical...

A panel of international scientists moved the minute hand of the "Doomsday Clock" back one minute on Thursday. It was the first time in two years that the clock had been adjusted, and the 18th time since its inception in 1947 when it was set to seven minutes before midnight. This year's slight move away from midnight, the metaphorical apocalypse, indicates that the world has inched away from nuclear or environmental disaster.  However, the scientists, including 19 Nobel laureates,...

Lawrence Krauss, a theoretical physicist and cosmologist at Arizona State University, will co-chair the Board of Sponsors of the Bulletin of Atomic Scientists with Nobel Laureate Leon Lederman. Together they plan to re-energize a national discussion on the reduction of nuclear weapons stockpiles, and a commitment to fight proliferation and encourage disarmament efforts."With a new administration in Washington, it will be an unprecedented opportunity to re-examine our policy on missile...

But gravitational waves may be more sensitive probe of early universe physics than previously thoughtA team of researchers from Case Western Reserve University has found that gravitational radiation"”widely expected to provide "smoking gun" proof for a theory of the early universe known as "inflation""”can be produced by another mechanism. According to physics scholars, inflation theory proposes that the universe underwent a period of exponential expansion right after the big...

When Dutch astronomer Willem de Sitter proposed a static model of the universe in the early 1900s, he was some 3 trillion years ahead of his time. Now, physicists Lawrence Krauss from Case Western Reserve University and Robert J. Scherrer from Vanderbilt University predict that trillions of years into the future, the information that currently allows us to understand how the universe expands will have disappeared over the visible horizon. What remains will be "an island universe" made from...

If you've ever wondered about the ultimate fate of the universe, Lawrence Krauss and Robert Scherrer have some good news - sort of. In a paper published online on April 25 in the journal Physical Review D, the two physicists show that matter as we know it will remain as the universe expands at an ever-increasing clip. That is, the current status quo between matter and its alter ego, radiation, will continue as the newly discovered force of dark energy pushes the universe apart. "Diamonds may...

Word of the Day
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
