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 years, we’ve believed that the universe is a vast, uniform expanse, with the same properties stretching across the cosmos ...

Learn how in just six months, the NASA team has mapped the entire universe in 102 colors.

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 ...

Before there was light, there was cosmic inflation. Before life, planet Earth, the first galaxies — and even before the violent explosion of hot dense primordial stuff scientists traditionally have ...

Cosmic inflation tries to describe one brief but crucial phase in the Big Bang that launched the universe onto its expansion course. Credit: Christine Daniloff / MIT / ESA / Hubble / NASA Many ...

The Universe is big, as Douglas Adams would say. The most distant light we can see is the cosmic microwave background (CMB), which has taken more than 13 billion years to reach us. This marks the edge ...

We'll cut right to the chase: This video of Stanford Professor Andrei Linde finding out about yesterday's big discovery of "smoking gun" evidence of cosmic inflation (the "first tremors of the big ...

In this video, we explore how gravitational waves from the Cosmic Microwave Background (CMB) could illuminate the mysteries of the Big Bang. The discussion includes the CMB and its polarization, ...

Is the universe 'tuned' to support life, and ultimately us? Physicists Nemanja Kaloper and Alexander Westphal have proposed ways to test this Anthropic principle. (Image of deep star field from the ...

The idea of a multiverse consisting of “parallel universes” is a popular science fiction trope, recently explored in the Oscar-winning movie Everything Everywhere All At Once. However, it is within ...

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 ...
