If you squeeze enough stuff into one place, space-time itself will contract in a sweet cosmic kiss known as a black hole. As far as Einstein’s sums go, that “stuff” includes the massless glow of electromagnetic radiation. Given E = mc2which describes the equivalence between mass and energy, the energy of light itself should – … Read more
Using gravitational lensing, scientists have discovered that dark matter can extend more than a million light-years from galactic centers, proposing significant adjustments to our theories of gravity or the concept of dark matter itself. Credit: SciTechDaily.com Groundbreaking new research shows that the rotation curves of galaxies remain flat far away, confirming the predictions of modified … Read more
The rapid formation of supermassive black holes in the early universe continues to baffle astronomers, and new observations from the James Webb Space Telescope have only deepened the mystery; even challenge existing models of cosmic evolution. The James Webb Space Telescope (JWST), equipped with the advanced Mid-Infrared Instrument (MIRI), allows scientists to delve deeper into … Read more
An illustration of distant quasar, supermassive, black hole-powered objects that can be used to constrain the parameters of gravity theories. Credit: ESO/M. Kornmesser A recent study explored teleparallel gravity and its potential to resolve the tension surrounding the expansion of the universe in a way that general relativity cannot. In the early 20th century, our … Read more

A TikToker has opened up about her theory on why we never really die, and it’s scaring people. You know that feeling after a night out where you go back to a friend’s house and sit there until the early hours, talking about random and slightly bizarre ideas or experiences so often that you feel … Read more

Teflon objects (orange cylinders) were placed in a waveguide with a rectangular cross-section. Then, an electromagnetic signal (blue wavefront) was injected from the right to obtain information about the metal cube, shown in gray. By measuring the wave field in … Read more

This diagram shows how a catalyst consisting of a few layers of iridium oxide (IrOX) over a titanium nitride (TiN) carrier can efficiently store oxygen (O2), hydrogen ions (H+), and electrons (e.g–) from water molecules (H2O) in an acidic electrolyte. … Read more
This diagram shows how a catalyst consisting of a few layers of iridium oxide (IrOX) over a titanium nitride (TiN) carrier can efficiently store oxygen (O2), hydrogen ions (H+), and electrons (e.g–) from water molecules (H2O) in an acidic electrolyte. This ‘oxygen evolution reaction’ is the more challenging of the two reactions required to split … Read more
