In this video, we explore the Big Bang theory and common misconceptions surrounding it. The Big Bang theory suggests an ...

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 ...

Black holes that formed before the Big Bang could still exist today as ‘cosmic fossils’, potentially helping to explain the ...

Generally speaking, black holes are regions of spacetime where matter is compressed into a tiny space. Dark matter, meanwhile ...

For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of ...

A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always posed a problem. Physics can describe a great deal about the universe ...

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.

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 ...

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 ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first predicted by Albert Einstein back in 1915, could have given rise to cosmic ...

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 ...

Researchers have shown that a discrepancy in a key cosmic measurement in the early universe originates from a subtle statistical interplay between measurements of the cosmic microwave background (CMB) ...
