The question of whether the cosmos goes on forever is no longer just a late night thought experiment, it is a live research ...

This video walks you all the way to the last pages of reality, exploring what modern physics says about how the universe ...

Here’s what you’ll learn when you read this story: A new paper adjusts an equation that defines our universe in response to recent new data. The cosmological constant, which describes how our universe ...

In the beginning, the Big Bang happened, sending everything in the universe expanding outward and apart, from a dense hot point. Since then, all that matter and energy has continued to move outward, ...

Studies suggest that the universe's expansion is decelerating — but what could that mean for the future of the cosmos?

Gazing up at the stars at night, it’s easy to imagine that space goes on forever. But cosmologists know that the universe actually has limits. First, their best models indicate that space and time had ...

Knotted structures once imagined by Lord Kelvin may actually have shaped the universe’s earliest moments, according to new research showing how two powerful symmetries could have created stable ...

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole. Parallels in the physics of the universe and that of black holes have led ...
