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 ...

Astrophysicists have presumed for nearly a century that the universe will just keep expanding for all eternity, driven by an invisible force called dark energy. But new data suggest that this is ...

The question of whether the cosmos goes on forever is no longer just a late night thought experiment, it is a live research problem that cuts to the heart of modern physics. Astrophysicists are using ...

The surface of Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, good ol' Earth helps us understand what the universe might be doing beyond ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when all of space, time, and energy were born from a single infinitely dense ...

Cosmologists have long treated black holes and the Big Bang as separate extremes of physics, one swallowing light, the other birthing space and time. A provocative line of research now suggests those ...

AUSTIN (KXAN) — A commonly held belief that the universe is rapidly expanding may be wrong. A new paper published this month suggests the universe’s expansion might be slowing down and it could mean ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or mathematician to tell you about fascinating ideas from their corner of the ...
