Dark Energy: What is dark energy? One of science’s great mysteries, explained

Paris: Deep energy Makes about 70 percent of the universe, yet we do not know anything about it.
About 25 percent of the universe is equally mysterious dark matterFor everything, except just five percent that we can see and touch, substances made of atoms.
Dark Energy is the placeholder name that scientists have given to unknown force, which expands rapidly and rapidly over time.
But some recent cosmic clues are removing the leading principle for this event, which means that humanity will eventually have to rethink our understanding of the universe.
And with targeting the problem with many new telescopes, scientists hope that there will be some concrete answers soon.
Here you need to know what many scientists have said the greatest secret in the universe.
So what is dark energy really?
No one knows. It is invisible and does not interact with substance or light.
And it also cannot be present.
This story begins, like everything, about 13.8 billion years ago in Big Bang, when the universe began to expand for the first time.
Since then, there has been a “cosmic tug-of-war” between the two mysterious forces, a theoretical astronomer physicist at the University of Chicago told AFP.
Dark matter is considered to pull the galaxies together, while the dark energy separates them.
During the first nine or so many billion years of the universe, “Dark Matter was winning,” the galaxies and everything else, said Framinies.
Dark energy then attained the upper hand, starting to speed up the expansion of the universe.
However, for most history, scientists had very little idea that this almighty quarrel was going on. He thought that the expansion of the universe would start slowing down due to gravity.
Everything changed in 1998 when two separate groups of astronomers noticed that the distant stars called Supernova were far away as they should be.
This discovered that the universe is not just expanding – it is so fast and sharp.
So what can be the reason for this acceleration? He gave a name to this strange force: Dark Energy.
What are the main principles?
The major principle has long been that empty space produces dark energy.
Think of a cup of coffee, Fraveman said.
“If I remove all particles from the cup of coffee, then we still have energy due to what we say. Quantum vacuum,” He said.
This energy of empty space is known as Cosmic continuityThis is the principle used in the standard model of Cosmology, Lambda-CDM, which is our best estimate for how the universe works.
But in recent years, many scientific results have appeared to support a rival principle, called the Evolving Dark Energy, which has brought the standard model into question.
On Wednesday, new results of dark energy spectroscopic instrument gave the latest hints that dark energy could actually weaken over time.
However, the scientists behind the research have been emphasized that there is no definite evidence yet.
If proved correct, it will dismiss that dark energy is a universe constant.
It may not be the energy of empty space, as the empty space does not change, “Firman explained to a prominent proposer of theory.
To change the dark matter, this will require some incredibly the existence of light, as yet-unknown particles.
Another possibility is that there is something wrong with our calculation – or our understanding of gravity.
Einstein’s principle of relativity has surpassed an incredible amount of scientific investigation in the last century, and has repeatedly proved correct.
There is no evidence that Einstein was wrong, but is a “slight room” to change its principle when the universe comes on a large scale.
When could we know more?
Soon The best way to understand dark energy is to see a huge health of the sky, with more and more data in the galaxies as much as possible.
And a group of new telescopes is just working to do this.
On Wednesday, Europe Euclid space telescope Since its launch in 2023, he released its first astronomical data, but any dark energy results are a few years away.
NASA’s Nancy Grace Roman Space Telescope, planned for launch in 2027, and low construction Vera robin observatory The goal of the problem will also be in Chile.
This is an exciting time for dark energy, said that he said that he expected a “fixed answer” over the next few years.
There is no time to waste, said that Framinies said.
“Every minute we wait, the galaxies are disappearing from the scene.”
