From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens in the cosmos. It shapes planets and people, bends light into celestial ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new ...

An almost impossible alignment of galaxies that forms a giant magnifying lens could give astronomers an unprecedented deep view of the universe. The Carousel Lens—named for its concentric circular ...

Gravity is invisible, yet it governs the cosmos, warping spacetime and bending light. This video explores Einstein’s general ...

We could drastically overcount the number of galaxies present in the early Universe due to the impact of gravitational lensing. Wow. Is the effect really that similar to a concave/convex lens? The pic ...
