How Did the Universe Begin: Hot Big Bang or Slow Thaw?

Posted on by

25.02.2014 - (idw) Ruprecht-Karls-Universitt Heidelberg

Did the universe begin with a hot Big Bang or did it slowly thaw from an extremely cold and almost static state? Prof. Dr. Christof Wetterich, a physicist at Heidelberg University, has developed a theoretical model that complements the nearly 100-year-old conventional model of cosmic expansion. According to Wetterichs theory, the Big Bang did not occur 13.8 billion years ago instead, the birth of the universe stretches into the infinite past. This view holds that the masses of all particles constantly increase. The scientist explains that instead of expanding, the universe is shrinking over extended periods of time.

How Did the Universe Begin: Hot Big Bang or Slow Thaw? Heidelberg physicist develops a new theoretical model in which the Big Bang stretches into the infinite past

Did the universe begin with a hot Big Bang or did it slowly thaw from an extremely cold and almost static state? Prof. Dr. Christof Wetterich, a physicist at Heidelberg University, has developed a theoretical model that complements the nearly 100-year-old conventional model of cosmic expansion. According to Wetterichs theory, the Big Bang did not occur 13.8 billion years ago instead, the birth of the universe stretches into the infinite past. This view holds that the masses of all particles constantly increase. The scientist explains that instead of expanding, the universe is shrinking over extended periods of time.

Cosmologists usually call the birth of the universe the Big Bang. The closer we approach the Big Bang in time, the stronger the geometry of space and time curves. Physicists call this a singularity a term describing conditions whose physical laws are not defined. In the Big Bang scenario, the spacetime curvature becomes infinitely large. Shortly after the Big Bang, the universe was extremely hot and dense. Prof. Wetterich believes, however, that a different picture is also possible. If the masses of all elementary particles grow heavier over time and gravitational force weakens, the universe could have also had a very cold, slow start. In that view, the universe always existed and its earliest state was virtually static, with the Big Bang stretching over an infinitely long time in the past. The scientist from the Institute for Theoretical Physics assumes that the earliest events that are indirectly observable today came to pass 50 trillion years ago, and not in the billionth of a billionth of a billionth of a second after the Big Bang. There is no longer a singularity in this new picture of the cosmos, says Prof. Wetterich.

Wetterich stresses that this in no way renders the previous view of the Big Bang invalid, however. Physicists are accustomed to describing observed phenomena using different pictures. Light, for example, can be depicted as particles and as a wave. Similarly, his model can be seen as a picture equivalent to the Big Bang. This is very useful for many practical predictions on the consequences that arise from this new theoretical approach. However, describing the birth of the universe without a singularity does offer a number of advantages, emphasises Prof. Wetterich. And in the new model, the nagging dilemma of there must have been something before the Big Bang is no longer an issue.

BLR Aerospace Offers Customized ROI Analysis During Heli-Expo 2014

Posted on by

ANAHEIM, Calif., Feb 24, 2014 Throughout Heli-Expo 2014, operators of Bell Medium helicopters may visit BLR Aerospace (Exhibit 5743) for a custom return on investment (ROI) report that will instantly estimate their individual payback period and ongoing savings for the investment made in the FastFin Tail Rotor Enhancement and Stability System.

Operators who take advantage of the analysis will better understand how FastFin installation impacts them financially, in addition to the proven operational advantages it delivers, said Dave Marone, Vice President of Sales and Marketing for BLR Aerospace. When you factor in the additional useful load, access to higher density altitudes, improved stability and increased wind azimuth tolerance, FastFin offers a compelling value proposition with empirical benefits while enhancing safety.

With FastFin installed, most operators will receive between a 10 and 90 percent increase in useful load depending on specific model and density altitude. The FastFin system includes two parallel stall strips on the tailboom and a reshaped vertical fin. FastFin optimizes airflow around the tailboom, dramatically improving tail rotor authority and wind azimuth tolerance. FastFin also improves aircraft stability, positively impacting operating costs by reducing cycle fatigue in structures and torque requirements on tail rotor rotating components.

In 2010, Bell Helicopter made FastFin standard equipment on new Bell 412EPs, and today more than 600 FastFin systems are operating worldwide, supporting diverse missions across all rotorcraft market segments. From firefighting to heliskiing, from sea level to the most challenging density altitudes, FastFin delivers when needed most.

A Connecticut-based aerospace firm is expanding to North Charleston to support Boeing.

Kaman Aerospace Group announced Tuesday that its subsidiary, Kaman Engineering Services, has a new office at the Clemson University Restoration Institute on the old Navy base, and will place a team of workers near Boeing's jet-building operation near Charleston International Airport.

The company did not say how many workers it would bring to North Charleston.

The office will support the growing aerospace industry in the Southeast, said Jim Larwood, president of Kaman Aerosystems.

"Kaman Engineering Services provides a unique, high-level engineering skill set and competency that aligns with the needs of Boeing S.C.'s operation," Larwood said in a statement. "This investment is one of several investments in Kaman's strategy of geographic diversification, and we are pleased to be part of the growing research and development community in the Charleston region."

The company, working as stress liaison, will work with Boeing's 787 Dreamliner program structures team.

"Kaman's on-site teams will include lead engineers to provide the greatest impact of the co-location and (will) support the Boeing engineering teams," said Cliff Ward, general manager of Kaman Engineering Services.

Gov. Nikki Haley welcomed the company's announcement and said the aerospace sector is a major driver of the state's economy.

"Seeing Boeing suppliers like Kaman Engineering Services opening new offices in South Carolina speaks volumes for our economic future," the governor said.
