One of the most powerful instruments known to the world for 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 distance markers of galaxies shows that the cosmic distance has expanded twice as much as 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 andGeorges Lemaître, who first attempted to measure the universe in 1929). The Hubble constantis 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 magnetron 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.”
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 light-speed 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.
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?
