New Measurements Point to an Error Made Regarding the Expansion of the Universe

Whether we like it or not, the Universe is constantly expanding, and nobody knows for sure where this phenomenon will lead to. We do know that the dark energy is the main cause of the accelerated expansion of our Universe. Einstein made his biggest blunder when he contradicted the idea of an everlasting expansion of our Cosmos, but he later admitted his mistake.

You can easily tell nowadays how sure astronomers are about the fabric of spacetime constantly getting larger. But there is still a lot more to learn about this perpetual phenomenon.

The measurement of the Hubble Constant is wrong

The Hubble Constant means the rate of expansion of the Universe, and a recent study claims that scientists had measured it wrong. A team of researchers discovered that there was a discrepancy between the previously obtained measurements of the Hubble Constant and the value that gets predicted by the model that belongs to the cosmic microwave background from the Planck Satellite.

James Braatz from the National Radio Astronomy Observatory (NRAO) declared:

We find that galaxies are nearer than predicted by the standard model of cosmology, corroborating a problem identified in other types of distance measurements. There has been debate over whether this problem lies in the model itself or in the measurements used to test it. Our work uses a distance measurement technique completely independent of all others, and we reinforce the disparity between measured and predicted values. It is likely that the basic cosmological model involved in the predictions is the problem,

Scientists first discovered that the Universe is expanding in 1929, when the American astronomer Edwin Hubble observed that many galaxies have a red shift. According to the Doppler effect, this means that those objects are moving away from us. That discovery revolutionized cosmology forever, as it was also the moment when scientists discovered that there are many other galaxies in the Universe besides the one we’re living in.
