Every astronomy textbook tells us that soon after the Big Bang, there was a period of exponentially accelerating expansion called cosmic inflation. In a tiny fraction of a second, inflationary ...

Researchers have discovered a new generic production mechanism of gravitational waves generated by a phenomenon known as oscillons, which can originate in many cosmological theories from the ...

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 ...

For a group of scientists who profess to love the symmetries in nature, cosmologists and astronomers spend an awful lot of time looking for and analyzing imbalances in the cosmic architecture. A new ...

The approach parallels the way cosmologists go about inferring the history of the universe. Like fossils, astronomical objects are not randomly strewn throughout space. Rather, spatial correlations ...

In the first moments after the Big Bang, the Universe was able to expand even billions of billions of billions of times faster than today. Such rapid expansion should be due to a primordial force ...

TO COOK up planets, stars and people, the universe had to be preheated. In the first slivers of a second after the big bang, the universe expanded exponentially in a process called inflation, leaving ...

According to the standard picture, the Universe sprang into being about 14 billion years ago, as a space filled with matter and radiation of nearly infinite temperature and density. At birth, the ...

When the European Space Agency’s Planck mission team unveiled the most detailed map yet of fluctuations in the cosmic microwave background — the afterglow of the Big Bang — in March, the map was seen ...

Researchers have discovered a new generic production mechanism of gravitational waves generated by a phenomenon known as oscillons. Researchers have discovered a new generic production mechanism of ...
