Nasa on Thursday revealed that the Hubble Space Telescope completed a nearly 30-year marathon of data collection
With this data, Hubble was able to identify dozens of markers for space and time to help scientists measure the expansion rate of the universe.
However, the more precise those measures become over the years, the more they indicate that “something weird” is happening in space, Nasa said.
There is a huge discrepancy between the universe’s current rate of expansion compared to observations from right after the Big Bang.
Scientists are unable to explain this phenomenon, which they say “predicts a different expansion value,” per Nasa.
The cause of this discrepancy remains a mystery.”
“But Hubble data, encompassing a variety of cosmic objects that serve as distance markers, support the idea that something weird is going on, possibly involving brand new physics.”
Researchers have been studying the universe’s expansion rate since the 1920s using measurements by astronomers Edwin P. Hubble and Georges Lemaître.
In 1998, this led to the discovery of dark energy, which Nasa describes as “a mysterious repulsive force accelerating the universe’s expansion”.
