Record measurement of universe suggests 'something is fishy'

The Astrophysical Journal's thorough investigation found that two methods for estimating the universe's expansion speed varied significantly.

The research found that just 5% of the cosmos is regular stuff, while the remainder is dark matter and dark energy, which are yet unknown.

33.8 percent is matter and dark matter, which may be some undiscovered subatomic particle.

The research corrected Pantheon project data from two years earlier and improved computations.

Pantheon+ and the SH0ES supernova collaboration found the most precise measurement of the universe's expansion.

The cosmos is expanding 73.4 kilometres per second every megaparsec, or 3.26 million light years.
