Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, known as quantum foam. It was a state where spacetime was unstable, and ...

Cosmic inflation is a popular scenario for the earliest phase in the evolution of the Universe CREDIT A. Ijjas, P.J. Steinhardt and A. Loeb (Scientific American, February 2017) Astrophysicists say ...

For a fraction of a second after the big bang occurred 13.8 billion years ago, most physicists believe, the newborn universe dramatically ballooned in size, jumping from being smaller than a proton to ...

In the earliest moments after the universe was born, everything changed—fast. This rapid expansion, known as cosmic inflation, was theorized to solve problems in the Big Bang model. It explains why ...

The cosmos is riddled with evidence that the universe began with an unfathomably rapid expansion — even faster than in traditional Big Bang theories — but scientists don’t know why it happened. A ...

Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki University suggests these signals might carry “beats” — patterns formed by ...

For decades, scientists have viewed the Big Bang as the starting point of space and time. But research into cosmic inflation—the lightning-fast expansion that likely occurred before the Big Bang ...

Last year’s reports that the BICEP2 telescope had uncovered evidence for cosmic inflation turned out to be a false alarm, but researchers in the field haven’t given up. Matthew R Francis describes how ...

galaxies — should be bigger than recently reported, according to a new (WMAP) concluded that space is flat, or Euclidian, instead of being curved, said Dr. Richard Lieu, a professor of physics at UAH.
