Roughly 14 billion years ago, a tiny pinpoint of extreme heat and density erupted in a grand explosion, leading to the creation of between 100 billion and 2 trillion galaxies, one of them being our ...

Cosmology is already a complicated field of study, so switching up the variables is extra rough.

No one knows what kicked off the Big Bang that eventually allowed the stars to begin forming. Adolf Schaller for STScI, CC BY How can a Big Bang have been the start of the universe, since intense ...

Physicists have taken the Universe’s temperature, revealing the searing trillion-degree heat of the Big Bang’s first plasma.

The universe may not have begun with the Big Bang as is generally thought but from the collapse of a massive black hole, a new theory suggests. That is to say this model of cosmology explains the ...

Evidence now suggests the universe’s expansion has started to slow, not speed up. The findings imply dark energy is weakening ...

Findings from a new study into the cosmic "afterglow" may rewrite the history of the universe, according to researchers. This afterglow—the "cosmic microwave background" (CMB), the relic radiation ...

Evidence suggests the universe’s expansion has started to slow, not accelerate. The results imply dark energy is weakening and evolving faster than previously believed.

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously ...

In a world that often measures itself in days, years, decades and centuries, a second seems insignificant. But a lot can happen in an instant. It takes a lightning bolt just 30 microseconds to strike ...
