What’s Wrong with the Hubble Constant?
<p>It is well known that the Universe is not static; it is constantly expanding, and what’s more, it is accelerating. Currently, the exact mechanism of expansion is unknown, but this acceleration is due to the mysterious “dark energy”. Because of it, all galaxies are moving away from each other, and the further they are, the faster they recede. Edwin Hubble was the first to describe in detail and formulate the law of galaxies’ recession in the early 20th century.</p>
<p>Hubble’s law is formulated as follows: A linear relationship exists between the distances to galaxies and the velocities of their recession. The further a cosmic object is from the observer, the faster it moves away.</p>
