Cosmologists are scratching their heads after the latest measurements of just how fast the universe is expanding raises more questions than answers.
Scientists have been trying to pin down the exact value of the Hubble Constant, a number that describes how far galaxies are receding over a specific time and distance as the universe expands, for nearly a century. Georges Lemaître, a Catholic priest and physicist who also first proposed the Big Bang theory (no, not the TV show), attempted to calculate that number in 1927.
Thanks - Technology - Scientists - Data - Wizardry
Now, thanks to better technology, scientists can actually rely on real data rather than just mathematical wizardry. The latest measurement made by a large team of cosmologists known as the H0LiCOW collaboration, which stands for H0 (an abbreviation for the Hubble Constant) and Lenses in COSMOGRAIL’s Wellspring confirms that the universe appears to be expanding faster than expected – and can’t be explained by the current standard model.
“There has been an intriguing pattern of differences in the Hubble Constant that appear to depend on which end of cosmic history its value is measured,” Adam Reiss, a professor of physics and astronomy at John Hopkins University, who isn’t part of the H0LiCOW team explained to The Register. Reiss was part of the trio of physicists who won the Nobel Prize in Physics in 2011 for discovering that the universe is expanding at an accelerated rate.

“This has been widely known as 'The Hubble Tension'. Measurements in the 'Late Universe' - or the present time - cluster around 73 kilometers per second per megaparsec. Measurements from the 'Early Universe' - or shortly after the Big Bang - get a value of about 67 kilometers per second per megaparsec.”
“Of course we should get the same answer at either end assuming we understand the physics of the universe. There is a...
