Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their ...

Scientists say microscopic wormholes could explain discrepancies in cosmological constants and affect our understanding of ...

Let's rewind the clock back…oh, I don't know, let's say a hundred years. It was 1917, and Einstein had just developed his ...

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

The geometry of space, the setting in which physical laws operate, may hold clues to some of the biggest unanswered questions in fundamental physics. The underlying structure of spacetime itself could ...

Physicists have uncovered a shocking twist in the fate of the universe—backed by real data and a precise timeline.

The universe is expanding. That much is clearer. But it’s less clear whether this expansion is accelerating or slowing down.

But new studies suggest that one of his most famous ideas, the cosmological constant, may not be fixed after all. If true, it could mean the universe is destined to collapse rather than expand forever ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

A century ago, a star in Andromeda named V1 launched a revolution in astronomy, revealing its true immensity and the origin ...

ABSTRACT: It is known that the cosmological constant can be dynamically tuned to an arbitrary small value in classes of scalar tensor theories. The trouble with such schemes is that effective gravity ...
