A study says the universe could eventually collapse because of weak dark energy

Dark Energy: Why the Universe is Decaying and Why It Could Collapse Over the Course of Millennias in a New Way

“We will use those numbers and we’ll try to find what is it, exactly, this dark energy. Is that a modification to gravity? “Is this a new formula of energy in the universe?”

He’s studying dark energy from an earlier time in the universe’s existence than DESI. It looks at the sound waves from the universe’s beginning.

There is no evidence to show the universe has already stopped expanding and is collapsing on itself, Ishak says. There will not be another 20 billion years of that if that were to happen.

If the findings hold up, they could force cosmologists to revise their standard model for the history of the Universe. The model usually assumed that dark energy is an inherent property of empty space and that it will not change over time.

If dark energy can be divided into different components, this will lead to a new way of thinking about the beginning of dark energy. The properties of dark energy have to be better scrutinized in the future.

More than 900 researchers from all over the world presented their findings at the American Physical Society’s Global Physics Summit in Anaheim, Calif.

According to new research, weak Dark Energy could cause the universe to collapse over the course of billions of years.

The Redshift of an Object: Observing the Expansion History of the Universe with a Robotic Spectrometer

“Now I’m really sitting up and paying attention,” says Catherine Heymans, an astronomer at the University of Edinburgh, UK, and the Astronomer Royal for Scotland.

Kitt Peak National Observatory is where the DESI telescope is located. It uses 5000 robotic arms to point at selected points where galaxy and quasars are located. 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.

Researchers are looking at the density of the universe to identify differences that are from sound waves that used to exist before stars began to form. They are the largest known features of the Universe, as their scale has grown by 1,000 to 150 megaparsecs over the course of the last decade.
