For a quarter century, cosmology has rested on a simple but audacious idea: that a fixed “cosmological constant” drives the ...

The universe may be asymmetric, not identical in all directions The cosmic dipole anomaly challenges the standard Lambda-CDM ...

Matrix models have emerged as a powerful framework in theoretical physics, offering a nonperturbative approach to describing quantum space-time. In these models, fundamental degrees of freedom are ...

In the early 2000s, it seemed that cosmologists had solved the largest and most complex puzzle of all: how the universe works. “There was this amazing moment when all of a sudden, all the pieces in ...

What is the actual speed and direction of our solar system as it moves through the cosmos, and how does this compare to longstanding cosmology models? This is what a recent study published in Physical ...
