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 ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

The fundamental constants of the Universe appear to be fine-tuned with incredible precision to allow for life. The slightest variation would make our existence impossible, raising a profound question.

At 11:30 one night in May 2024, a graduate student, Chuankun Zhang, saw a signal that physicists have sought for 50 years. As a peak rose from the static on his monitor at the research institute JILA ...

Let’s face it: We are massively failing at change. According to research from Gartner published last May, employees’ willingness to support enterprise change collapsed to just 43% in 2022, compared to ...

Astronomers have made new measurements of the Hubble Constant, a measure of how quickly the Universe is expanding, by combining data from the Hubble Space Telescope and the James Webb Space Telescope.
