The universe is expanding at dizzying speed

NASA's Spitzer space telescope data gives scientists the most accurate view of the universe's rate of expansion. Accordingly, the universe is expanding at the fastest rate ever recorded.

Spitzer telescope observations released by the US Aerospace Agency (NASA) in 2003 show that the universe is expanding at a rate of 74.3 plus minus 2.1 km per second over a wide area. a megaparsec (equivalent to about three million light years). It is rated as the fastest expansion rate since humans discovered the universe bulged every day.

The scale is created by creative experts to compare distances
between cepheids, which helps determine the best degree of expansion of the universe.

In 1920, American astronomer Edwin P. Hubble was the first to discover that our universe was not static. In fact, Mr. Hubble has proven that space has expanded greatly since it began to take shape after the Big Bang 13.7 billion years ago. After that, the world was once again surprised when the 1990 astronomers' research proved that the expansion of the universe is accelerating day by day. This discovery won the 2001 Nobel Prize in Physics.

Since astronomer Hubble discovered the expansion of the universe, scientists have always tried to measure the expansion of space with the measurement formula called Hubble's Constant. However, this calculation became not very accurate after the space telescope, Hubble, introduced new figures to help people better understand the age and size of the space.

Expert Wendy Freedman works at the Carnegie Science Institute Observatory in Pasadena, California: 'More than a decade ago, the concept of' precision 'and' cosmology 'could not exist in the same sentence. But now, we can pretty much determine the parameters of the universe, with only a few percent of the errors. '

Combining the Hubble Constant with the most advanced space observation devices, NASA can calculate accurately and independently of the 'dark energy' power , against gravity to extend the universe more than when it was formed.

The reason is that humans can discover dark energy thanks to the Spitzer telescope using long wavelength infrared rays capable of penetrating cosmic dust clouds to reach the most remote areas of space. Accordingly, the Spitzer telescope focuses on tracking stars called cepheids. Based on the time it takes for infrared waves to respond, scientists can easily calculate the exact distance between the earth and those stars. The distance away from the experts noted is the speed of expansion of the universe.

Currently, Spitzer observes 90 stars called cepheids with much higher accuracy than previous studies. The most accurate and comprehensive parameters released by the Telescope in 2003 show that our universe is expanding at the fastest rate since it was discovered.
