These galaxies were used to measure the universe's expansion rate.
Verifying that dark energy is speeding up the universe's expansion;
So the universe's expansion has not been slowed because of gravity, which everyone thought it has accelerated.
We need to understand, measure, and quantify the Universe's expansion.

To measure the universe's expansion rate- a number known as the Hubble constant- astronomers typically look at stars and galaxies to see how fast they seem to be moving apart.
This invisible forceis said to be responsible for accelerating the Universe's expansion.
But since then, astronomers observing and measuring the universe's expansion have arrived at different values of the Hubble Constant, none of which seem to agree with one another.
In the process,it could answer big questions about dark energy and the universe's expansion.
Besides finding evidences about the universe's expansion, DESI would also help to set limits on theories related to gravity and the formative stages of the universe. .
Before the discovery,physicists thought that the attractive force of gravity would slower the universe's expansion over time.
From these measurements they calculated the Universe's expansion rate, known as the Hubble constant, to be 73.2 kilometres per second per megaparsec(a megaparsec equals 3.26 million light-years).
That corresponds to a possible future in which the force of gravity brings the universe's expansion to a halt- and then reverses it.
Dark energy became important for the Universe's expansion 6 billion years ago, and began dominating the Universe's energy content around the time our Sun and Solar System were being born.
This biblical claim for simultaneously finished and ongoing acts of creation, incidentally,is not limited to just the universe's expansion.
But by adhering to the eternal view in the interim,he had missed predicting one of the biggest discoveries in cosmology: the universe's expansion.
By assuming the rate of the Universe's expansion depended not just on time, but its scale as well, he showed there was no need for a quantum leap out of a singularity into a dense, voluminous space 13.82 billion years ago.
Particles that remain, like electrons and light particles(photons),are then very far apart due to the universe's expansion and rarely- if at all- interact.
Riess- who shared the 2011 Nobel Prize in physics for the discovery that the universe's expansion is accelerating- and his colleagues used NASA's Hubble Space Telescope to study 2,400 Cepheid stars and 300 Type Ia supernovas.
This discovery puzzled scientists,who long thought that the gravity of matter would gradually slow the universe's expansion, or even cause it to contract.
While its predecessor is credited withunveiling important discoveries including the acceleration of the universe's expansion, the JWST is expected to go even further by exploring the birthplaces of planets, stars, and first galaxies born after the Big Bang more than 13.5 billion years ago with its sensitive infrared cameras.
In 1998, two different teams--the Supernova Cosmology Project and the High-z Supernova Search Team--both failed at their goalof measuring the deceleration of the universe's expansion.
Recent measurements with telescopes and space probes have shown that a mysterious force- a dark energy- fills the vacuum of empty space,accelerating the universe's expansion.
By collecting specific wavelengths of light from these galaxies, DESI will let astronomers measurehow quickly these objects are moving away from us because of the universe's expansion.
Early this century, scientists studying the outer reaches of the universe confirmed that not only is everything moving apart from everything else,as you would expect in a universe that began in hot, dense big bang, but that the universe's expansion also seems to be accelerating.
It's what physicists in real life are currently calling"dark energy",as an explanation for the accelerating expansion of the universe- which has only recently been discovered and flies in the face of the previous notion that the universe's expansion should be slowing down because of gravity.
As of right now, the current hypothesis states that the Universe is made up of 4.9 percent normal matter- the stuff we can see, such as galaxies and stars- 26.8 percent dark matter, and 68.3 percent dark energy, a hypothetical type of energy that's spread throughout the Universe, and which might be responsible for the Universe's expansion.
Those factors are the reddening of light due to the expansion of space, the universe's dynamic nature, and the absorption of light by intergalactic dust and gas.
That turns out to be dark energy,” Harvey says-which only emerged again in 1998 to explain the universe's accelerating expansion. .
