In the late 1990s, observations of type Ia supernovae led to the astounding discovery that the universe is expanding at an accelerating rate. The explanation of this anomalous acceleration has been one of the great problems in physics since that discovery. We propose cosmological models that can...
The Universe is expanding at an ever increasing rate according to recent observations of supernovae. Astronomers believe that a certain class of supernova explosions - so-called type 1a supernovae - all have the same intrinsic luminosity, which means that their observed luminosity can be used to...
Astronomers also know that the universe is expanding at an accelerating rate. The standard model attributes this effect to a cosmological constant— a form of energy that pushes outwards against gravity’s inward pull, with equal strength throughout time. ...
Only in 1988 did astrophysicists first discover that the universe is expanding at an accelerating rate. This discovery was made by observing distant supernovae, showing that the universe expanded much more slowly a long time ago. "The behavior of the universe as a whole is like a tug of wa...
“Dark energy,” a mysterious force that counters gravity, has been proposed to explain why the universe is expanding at an accelerating rate. Mathematicians at UC Davis and the University of Michigan, Ann Arbor, argue for an alternative. Galaxy cluster image from the Hubble Space Telescope. ...
Astronomers have exploited this fortunate circumstance to study the expansion history of our Universe. They recently arrived at the fundamental conclusion that the Universe is expanding at an accelerating rate, cf. ESO PR 21/98, December 1998 (see also the Supernova Acceleration Probe web page). ...
