Researchers find new way of exploring the afterglow from the Big Bang by Staff Writers Waterloo, Canada (SPX) Apr 20, 2018
Researchers have developed a new way to improve our knowledge of the Big Bang by measuring radiation from its afterglow, called the cosmic microwave background radiation. The new results predict the maximum bandwidth of the universe, which is the maximum speed at which any change can occur in the universe. The cosmic microwave background (CMB) is a reverberation or afterglow left from when the universe was about 300,000 years old. It was first discovered in 1964 as a ubiquitous faint noise in radio antennas. In the past two decades, satellite-based telescopes have started to measure it with great accuracy, revolutionizing our understanding of the Big Bang. Achim Kempf, a professor of applied mathematics at the University of Waterloo and Canada Research Chair in the Physics of Information, led the work to develop the new calculation, jointly with Aidan Chatwin-Davies and Robert Martin, his former graduate students at Waterloo. "It's like video on the Internet," said Kempf. "If you can measure the CMB with very high resolution, this can tell you about the bandwidth of the universe, in a similar way to how the sharpness of the video image on your Skype call tells you about the bandwidth of your internet connection." The study appears in a special issue of Foundations of Physics dedicated to the material Kempf presented to the Vatican Observatory in Rome last year. The international workshop entitled, Black Holes, Gravitational Waves and Spacetime Singularities, gathered 25 leading physicists from around the world to present, collaborate and inform on the latest theoretical progress and experimental data on the Big Bang. Kempf's invitation was the result of this paper in Physical Review Letters, a leading journal in the field. "This kind of work is highly collaborative," said Kempf, also an affiliate at the Perimeter Institute for Theoretical Physics. "It was great to see at the conference how experimentalists and theoreticians inspire each other's work." While at the Vatican, Kempf and other researchers in attendance also shared their work with the Pope. "The Pope has a great sense of humor and had a good laugh with us on the subject of dark matter," said Kempf. Teams of astronomers are currently working on even more accurate measurements of the cosmic microwave background. By using the new calculations, these upcoming measurements might reveal the value of the universe's fundamental bandwidth, thereby telling us also about the fastest thing that ever happened, the Big Bang.
Unlocking the secrets of the universe Tempe AZ (SPX) Mar 01, 2018 Long ago, about 400,000 years after the beginning of the universe (the Big Bang), the universe was dark. There were no stars or galaxies, and the universe was filled primarily with neutral hydrogen gas. Then, for the next 50-100 million years, gravity slowly pulled the densest regions of gas together until ultimately the gas collapsed in some places to form the first stars. What were those first stars like and when did they form? How did they affect the rest of the universe? These are questi ... read more
