Extra Credit: Primordial gravitational waves. You may remember the kerfuffle about the BICEP2 "discovery" (and then un-discovery) of gravitational waves in the weak primordial "glow" of the Big ...

Their research provides some evidence that the signals they have found may be the result of gravitational waves from the earliest moments of the universe's existence and thus might constitute the ...

A new technique may sift out universe's very first gravitational waves. Identifying primordial ripples would be key to understanding conditions of the early universe. In the moments immediately ...

While much of CMB polarization is due to later density fluctuations that gave rise to galaxies, theory predicts that some of it came from primordial gravitational waves. Those waves are ripples in ...

Besides particles like sterile neutrinos, axions and weakly interacting massive particles (WIMPs), a leading candidate for the cold dark matter of the universe are primordial black holes—black holes ...

Those fractures would have released floods of gravitational waves, and a team of astronomers ... which gave rise to all of the primordial hydrogen and helium in the universe or distorted our ...

That should have magnified tiny ripples in the universe called primordial gravitational waves, which in turn left a stamp on light created some 13.5 billion years ago. That light still pervades ...

At present, the major method for exploring the origin of the universe is to search for primordial gravitational waves. The magnitude of these waves is directly determined by the energy scale of ...

Until recently, gravitational waves could have been a figment of Einstein ... Another possibility is tiny, primordial black holes, too small to be formed by standard means, which might have ...

Steady light signals from pulsars may be distorted by the gravitational wave background – a pervasive ... with quark-gluon plasma – a dense “primordial soup” of elementary particles ...

Gravitational waves are ripples in the fabric of space. Waves that originated in the early universe could carry important information about the phenomena that occurred there. When you purchase ...

Now, we might have a new way to detect primordial black holes, although in a severely limited form. This method comes via gravitational waves. First detected in 2015 by the LIGO gravitational wave ...
