A new Scientific Reports study proposes an extension of the electron Born self-energy (eBse) model, unveiling a mechanism for cosmic inflation driven by a constant potential energy density, thereby challenging the conventional ...
In the very early universe, physics were weird. A process known as inflation, during which the universe went from a single infinitesimal point to everything we see today, was one such instance of those weird physics. Now, ...

A team of astrophysicists say that cosmic inflation—a point in the universe's infancy when space-time expanded exponentially, and what physicists really refer to when they talk about the "Big Bang"—can in principle be ...

Early in its history, shortly after the Big Bang, the universe was filled with equal amounts of matter and "antimatter"—particles that are matter counterparts but with opposite charge. But then, as space expanded, the universe ...

As the Big Bang theory goes, somewhere around 13.8 billion years ago the universe exploded into being, as an infinitely small, compact fireball of matter that cooled as it expanded, triggering reactions that cooked up the ...

Most everybody is familiar with the Big Bang—the notion that an impossibly hot, dense universe exploded into the one we know today. But what do we know about what came before?

A team of scientists has proposed a powerful new test for inflation, the theory that the universe dramatically expanded in size in a fleeting fraction of a second right after the Big Bang. Their goal is to give insight into ...
