Not only is the Universe expanding, but its expansion is actually happening at a speed higher than was thought possible until recently. For many years now, physicists have been trying to establish the ...

The existence of electromagnetic radiation—light, radio waves, microwaves, X-rays, and so on—is one of the most important physical phenomena. Their theoretical understanding is one of the greatest ...

Lately, I’ve noticed something in my conversations with clients, colleagues, and even friends: Everyone feels like they’re running, yet getting nowhere. The pressure to adopt, integrate, and master ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

New research suggests dark energy, the mysterious force accelerating the universe’s expansion, may not be constant after all. Credit: SciTechDaily.com Astrophysicists at the University of Chicago have ...

If you've ever ready anything about cosmology, you'll have come across an astonishing statistic: all the matter around us, everything we see and touch, every star and gas cloud and planet, makes up ...

In 1998, astronomers made a startling announcement. Space-time, the unified phenomenon that comprises our universe and that was previously understood to be expanding, was actually not just growing, ...

Einstein’s theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own ...

Everything in the universe has gravity – and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...
