Static Black Holes Exert Pressure on Their Environment, Scientists Say In 1974, Stephen Hawking made the seminal discovery that black holes emit thermal radiation. Previous to that, black holes were believed to be inert. In new research, a duo of researchers from the Department of Physics and Astronomy at the University of Sussex shows that black…
The Journey to Define Dimension he notion of dimension at first seems intuitive. Glancing out the window we might see a crow sitting atop a cramped flagpole experiencing zero dimensions, a robin on a telephone wire constrained to one, a pigeon on the ground free to move in two and an eagle in the air…

The theory is that this new molten-salt technology will be “safer” and “greener” than regular uranium reactors, and so could help Beijing meet its climate goals. Yet is the country’s…
Physicists Just Accidentally Made a New Discovery About Black Holes Given that our first direct detections confirming the existence of black holes only took place in this century, humanity can be forgiven for not knowing a few things about these mysterious cosmic objects We don’t even know everything we don’t know – a fact that’s been made evident…
