Cosmologists a step closer to understanding quantum gravity
by Staff Writers
Portsmouth, UK (SPX) Jan 25, 2017


Dr Vincent Vennin.

Cosmologists trying to understand how to unite the two pillars of modern science - quantum physics and gravity - have found a new way to make robust predictions about the effect of quantum fluctuations on primordial density waves, ripples in the fabric of space and time.

Researchers from the University of Portsmouth have revealed quantum imprints left on cosmological structures in the very early Universe and shed light on what we may expect from a full quantum theory of gravity.

Dr Vincent Vennin, from the Institute of Cosmology and Gravitation said: "We haven't solved quantum gravity but we've learnt a little more about how it would work.

"Physicists do not yet know how to combine theories of gravity and the quantum world. Yet both play a crucial role in the very early Universe where the expansion of space is driven by gravity and cosmological structures that arise from quantum fluctuations.

"Quantum fluctuations during inflation are thought to be the origin of all structure in the Universe. Structures we see today such as galaxies, stars, planets and people can be traced back to these primordial fluctuations."

The paper is co-authored by Professor David Wands, Dr Hooshyar Assadullahi, Hassan Firouzjahi and Mahdiyar Noorbala. It was published in the Physical Review Letters.

China to set up gravitational wave telescopes in Tibet
Lhasa Tibet (XNA) Jan 10, 2017
China is working to set up the world's highest altitude gravitational wave telescopes in Tibet Autonomous Region to detect the faintest echoes resonating from the universe, which may reveal more about the Big Bang. Construction has started for the first telescope, code-named Ngari No.1, 30 km south of Shiquanhe Town in Ngari Prefecture, said Yao Yongqiang, chief researcher with the Nationa ... read more
