The astronomers discovered that the universe is expanding at a slower rate than expected.
So far, measuring the speed of expansion of the universe, scientists used the Type Ia supernovae, which arise as a result of the explosion of white dwarfs. Since all known objects of this type seem to be identical, you could use them as cosmic beacons transmitting signals from distant corners of the universe. This makes it possible to measure the rate of expansion of the universe.
study conducted by researchers at the University of
Thanks to this research, astronomers have identified two groups of Type Ia supernovae. Some of them are closer to the Earth than previously thought, so all calculations performed had to be regarded as invalid. Therefore, if the universe is expanding at a slower pace than expected, the nature of dark energy and matter must be tested again.
