Research shows that we all misunderstood the universe

The conclusions of the recent study may cause many human laws of the universe to be rewritten.

Many previous studies have suggested that the universe was formed after the Big Bang 13.8 billion years ago, and has since expanded at an increasingly terrible rate. This speed is measured by the Hubble telescope.

However, recently, a study by physicists at Johns Hopkins University (USA) has proposed an extremely accurate measurement of the speed of the universe. And they found that the rate of expansion of the universe is 8% faster than what we still think.

The rate of expansion of the universe is faster than we thought.

Only 8%! It sounds so small, but this difference can make many laws about the universe rewritten. According to Professor Adam Riess, the research director: "I think we still have not grasped the rules of the universe."

If the universe expanded faster, this would mean that the force from the "dark matter " has become stronger since then. Big Bang explosion. While earlier, Professor Riess's own studies have suggested that dark matter is immutable.

Dark matter is no longer invariant.

Scientists have made some assumptions for this. In it, the first possibility that Professor Kevork Abazajian - cosmologist of the University of California - pointed out that the composition of dark matter is essentially not the same as what has been studied, but they can evolve over time. time.

Meanwhile, Professor Wendy Freedman of the University of Chicago does not rule out the possibility that this new measurement method may be misleading.

The composition of dark matter can evolve over time.

However, most experts believe that this finding has the potential to "change the basic theories of cosmology" - Professor Abazajian said.

The study is published in Nature.
