Researchers still have questions about how rapidly the universe is expanding, with new findings only deepening the mystery.
The universe is estimated to be expanding at a rate of 46 miles a second every megaparsec or more than 160,000 miles per hour, according to a new study published in the Astrophysical Journal.

These findings from the Pantheon+ method are in contrast to those when using the method of measuring cosmic microwave background radiation, which suggests the universe is expanding at a much slower 42 miles per megaparsec, give or take. The discrepancy between the two methods is typically known as the Hubble tension.
“We thought it would be possible to find clues to a novel solution to these problems in our dataset, but instead we’re finding that our data rules out many of these options and that the profound discrepancies remain as stubborn as ever,” Dillon Brout, who worked on the research, said in a statement.
Brout also told AFP about increased Hubble tension, saying, “It certainly indicates that potentially something is fishy with our understanding of the universe.”

The Pantheon+ project research also explored the universe’s composition, finding nearly two-thirds dark energy and nearly one-third matter and dark matter.
