It's a constant on SciNoFi that we do one post per episode of a given show. But as we all now know from watching the unexpectedly epic season finale of Fringe last week, constants can change, ...

For years, astronomers and physicists have calculated the age of our universe by measuring the time elapsed since the Big Bang and by studying the oldest stars based on the redshift of light coming ...

The kilogram is losing weight and many scientists agree that it's time to redefine it. They are hoping to redefine the kilogram by basing it on standards of universal constants rather than on an ...

In physics, there are a host of standard constants: the speed of light, the charge-to-mass ratio of the proton, and Planck's constant, to name just a few. Repeated measurements going back a few ...

It seems that nothing stays the same: not even the 'constants' of physics. An experiment suggests that the mass ratio of two fundamental subatomic particles has decreased over the past 12 billion ...

Not only does a universal constant seem annoyingly inconstant at the outer fringes of the cosmos, it occurs in only one direction, which is downright weird. Those looking forward to a day when science ...

The strength of the electromagnetic interaction, one of physics’s most fundamental constants, is actually very slowly changing, and has different values in different parts of the universe. This ...

Some things never change. physicists call them the constants of nature. Such quantities as the velocity of light, c, Newton’s constant of gravitation, G, and the mass of the electron, m e, are assumed ...
