When Albert Einstein told us about the relationship between mass,
energy, space and time, he assumed that the universe was static. Even
though his first equations showed that in fact the cosmos was moving
apart from some source, he thought that was a mistake: so he added a
fudge factor - what he called the cosmological constant, a way of
balancing the force of gravity. Later, he was to call the cosmological
constant the biggest mistake of his life. Astronomers started to prove,
almost before the ink dried on his equations, that galaxies were flying
apart, and the cosmos was in fact expanding from some point in space.
But now there's new evidence about that expansion rate - one that shows
that Einstein may have been right after all.
