The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

Embrace the flow, says a duo of mechanical engineers at North Carolina State University—the flow of energy, that is. The mantra you might normally hear from your yoga instructor could be an entirely ...

Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity. This effectively means that time is slower the closer ...

The James Webb Space Telescope found unexpectedly chemically mature galaxies. Turns out those JWST results match predictions ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

If you imagine the story of the universe as a film endlessly in post-production, cosmologists would be its obsessive editors, constantly tweaking the narrative. The version they are working with is an ...

Hilbert space theory and operator algebras provide a robust framework for analysing linear operators and their spectral properties, which are pivotal in both pure and applied mathematics. Hilbert ...

Rising launch cadences have dramatically increased orbital debris, posing critical risks to spacecraft and operations, as highlighted by incidents like the Shenzhou-21 stranding. The primary barrier ...

Optical aberration theory remains a fundamental component in the design and operation of space telescopes. With increasingly ambitious astronomical missions and the demand for high-resolution imaging, ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.
