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 ...

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 ...

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 ...

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 ...

The ‘inflationary’ model of cosmology explains many large-scale features of the Universe as the result of a primordial period of exponential, almost instantaneous cosmic expansion called inflation.

We're often told it is "unscientific" or "meaningless" to ask what happened before the Big Bang. But a new paper by FQxI cosmologist Eugene Lim, of King's College London, UK, and astrophysicists Katy ...

What happened in the first trillionth of a trillionth of a trillionth of a second after the Big Bang? Super-sensitive microwave detectors, built at the National Institute of Standards and Technology, ...

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.

Astrophysicists at the Harvard-Smithsonian Center have observed gravitational waves-- the first ever direct evidence of the Big Bang, the theory that the entire universe sprung into existence from a ...
