For many years, astronomers have relied on distant supernovae as cosmic beacons to study the universe and test the laws of physics. But while ...

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...

Mercury freezes at roughly minus 38.8 degrees Celsius, a temperature so far below everyday conditions that the silvery ...

Black holes that turn matter into energy could explain dark energy and answer two other cosmic questions. Now, the challenge ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

These universal constants include the speed of light in a vacuum, Newton’s gravitational constant, Planck’s constant (the scale at which quantum effects begin), and the masses of the fundamental ...

In his classic science-fiction story “The New Accelerator,” published in 1901, H. G. Wells describes a drug that speeds up a person’s metabolism by a factor of 1,000. For the two protagonists who ...

Proposals offering alternatives to Einstein’s relativistic theory of gravitation are almost as old as the theory itself. Einstein even saw them as the beginning of a path that could lead to quantum ...

You can roughly divide gamers into two camps nowadays, even if they don't actually realise that – those who've played their favourite systems on an OLED display ...
