One of the most powerful instruments known to the world when it comes to interstellar measurements is the Hubble Space Telescope. Hubble is currently on a much larger-scale mission – to determine how fast our universe is expanding.

Now, new findings show that the universe is not expanding at a uniform rate. Scientists are studying new data from the Hubble Space Telescope. They say that the expansion rate of other galaxies has become much faster than we originally expected and understood.

The biggest update on the Hubble constant and the resulting galactic distance markers shows that the cosmic distance has doubled in size compared to before. Scientists examining new data from the 32-year-old Hubble space telescope are trying to determine how fast the universe is expanding, and how much that expansion is accelerating, through a number known as Hubble constant (named after astronomers Edwin P. Hubble and Georges Lemaître, who first attempted to measure the universe in 1929). The Hubble constant is a very special number. It can give scientists a long-standing view of the universe.

“We have the most accurate measure of the expansion rate of the universe yet,” said Nobel laureate Adam Riess of the Space Telescope Science Institute (STScI) and Johns Hopkins University in Baltimore, Maryland. The telescope’s gold standard universe and cosmic mile markers Observations also show other galaxies are moving away from our Milky Way galaxy at a faster rate. They still can’t figure out why, so all they’re saying right now is still something weird going on.”

Riess is currently leading a team of scientists who have published a paper regarding data collected from the Hubble Space Telescope and it has been found that other galaxies are moving quite quickly compared to us. – shows a clear increase in the rate of cosmic expansion.

Einstein’s special theory of relativity holds that the speed of light in the universe is the fastest, and that all motion of matter cannot surpass the speed of light. However, in the standard model of the universe, the expansion of the universe exceeds the speed of light, in a way that has proved very difficult to understand, since the motion of matter cannot exceed the speed of light. the speed of light, so why is the expansion of the universe faster than the speed of light?

In fact, the essence of the answers to these questions is the difference between the expansion of the universe faster than the speed of light and the speed of light in the motion of objects. Simply put, the speed of light barrier can only be applied to objects with static mass, which cannot exceed the speed of light, whereas the expansion of the universe is the expansion of space-time. Space-time itself has no mass, and of course it is not limited by the speed of light.

The study of the expansion rate of the universe has been a topic that has fascinated scientists and astronomers for a very long time. From the initial studies carried out in the 1920s by astronomers Edwin P. Hubble and Georges Lemaitre until the discovery of “dark energy” in the late 1990s, advances in the field have made progress in the field. This happens slowly but steadily.

However, the Hubble Space Telescope has been providing a huge amount of data for research scientists, and NASA believes that something strange is happening in the universe as it is expanding rapidly. how.

Other NASA scientists said in a press release: “The cause of this discrepancy remains a mystery. But Hubble’s data, which includes many different cosmic objects, plays a role. distance markers, supporting the idea that something strange is happening, possibly related to an entirely new physical phenomenon.”

Cosmic expansion refers to the continuous expansion of the entire universe on a large scale, this was first discovered and provided by the famous American astronomer Edwin Hubble. In his memory, mankind’s first modern space telescope was named after him. After the Hubble Space Telescope was put into the sky, it greatly expanded humanity’s vision and deepened understanding of the universe.

Hubble came to a conclusion about the expansion of the universe in 1929 based on long-term observations. The conclusion is that the entire universe is expanding and homogenizing, all the galaxies are separate, getting further and further apart. From this he deduced Hubble’s law, which is simply expressed as: V = HD. Here V represents the rate of regress of the galaxy; H represents the Hubble constant, which is defined as the rate of regression of the galaxy at a distance of 10Mpc from us, in s/km; D represents the actual distance between the galaxy and us.

Mpc is a unit of megaparsec, and 1pc (parsec) is about 3.26 light years. This statement is fully consistent with Einstein’s description of general relativity, and resolves the contradiction between Einstein’s field theory and absolute space-time theory, thus adding a major and important piece of evidence to the model. the big bang universe, showing that the universe began with a singularity explosion, the expansion never stopping.
