What is Dark Energy? “Is it a Formula of Dark Energy in the Universe?” A panel discussion at the American Physical Society’s Global Physics Summit

We’ll try to find out what that dark energy is, by using those numbers. Is that a modification to gravity? “Is this a formula of energy in the universe?” he asked.

The latest results were presented at the American Physical Society in Anaheim, California, on 19 March, based on three years of data-taking, compared to one in April last year.

We thought that the universe would keep expanding and expanding and expanding, at a faster rate. Ishak says. “It [almost] becomes empty. Now, it is back to the table that the expansion of the universe also has the possibility that it will stop And eventually it will collapse.

“Is it just [that] we are missing something big in the model of our universe and we just don’t know it? We will have to stop, sit down and rethink our model of the universe due to the fact that we are just measuring things. “What it’s showing us is….it is actually a wild type of dark energy that we need to understand and we don’t understand it yet.”

If dark energy is a time-varying component it will allow for a completely different way of thinking about the origin of dark energy. “We have to think about how to scrutinize the properties of dark energy better from the current and future datasets.”

An international group of more than 900 researchers studying the expansion of the universe presented their findings on Wednesday during the American Physical Society’s Global Physics Summit in Anaheim, Calif.

According to the new research, the universe is at risk of collapsing on itself over billions of years because of a weakened dark energy.

The DESI telescope: mapping the expansion of the Universe using radio-loud spectroscopy (DESI-Lambda)

Catherine Heymans is an astronomer at the University of Edinburgh, UK, as well as the Astronomer Royal for Scotland.

The DESI telescope is located at Kitt Peak National Observatory near Tucson, Arizona. It uses 5,000 robotic arms to point optical fibres at selected points where galaxies or quasars are located within its field of view. The fibres then deliver light to sensitive spectrographs that measure how much each object is redshifted — meaning the degree to which its light waves were stretched by the expansion of space on their way to Earth. Researchers can estimate an object’s distance using its redshift, to produce a 3D map of the Universe’s expansion history.

Tracking the evolution of the BAOs can be used to reconstruct how the Universe has changed over time. The expansion switched from decelerating to an accelerated state around 5 billion years ago. Until last year, cosmology data were all consistent with dark energy being a cosmological constant — which meant that the Universe should continue to expand at an increasingly fast rate.
