When researchers from the Harvard-Smithsonian Centre for Astrophysics announced recently that they鈥檇 found echoes of the birth of the universe their discovery was hailed as 鈥榮pectacular鈥�, 鈥榚poch-making鈥� and 鈥榳orthy of a Nobel Prize'. In this week鈥檚 Science Caf茅 Adam Walton asks what all the fuss is about and asks some big questions about the big bang.

听

Adam鈥檚 panel of physicists and cosmologists take a look at the birth of the universe and why scientists believe everything started 14 billion years ago in a gigantic explosion of matter and energy. They explain some of the scientific terms associated with the recent announcement 鈥� ideas like gravitational waves, the cosmic microwave background and inflation. And they reveal that the universe will probably end not with a bang but a whimper!

Adam is joined by Dr. Hiranya Peiris from University College London who describes her research area as 鈥渢he fossilised heat of the big bang鈥� and Dr. Chris North from Dr. Stephen Fairhurst from Cardiff University鈥檚 School of Physics and Astronomy. Chris works on the Herschel Space Observatory and is a presenter on the 成人快手鈥檚 Sky at Night programme. And Stephen鈥檚 research is into gravitational waves, those ripples in space-time which are the focus of all the current excitement.
