Have Astronomers Uncovered Proof Of Dark Matter?2 min read

A team of American and Israeli astronomers may have uncovered the first-ever proof of the existence of the mysterious “dark matter,” one of the building blocks of the universe, while attempting to detect the earliest stars in the universe through radio wave signals.

The discovery by the team, led by Professor Judd Bowman of Arizona State University, which was published this week in the journal Nature by Professor Rennan Barkana, head of the Department of Astrophysics at Tel Aviv University’s School of Physics and Astronomy, suggests that the signal is proof of interactions between normal matter and dark matter in the early universe.

“Dark matter is the key to unlocking the mystery of what the universe is made of,” said Barkana. “We know quite a bit about the chemical elements that make up the earth, the sun and other stars, but most of the matter in the universe is invisible and known as ‘dark matter.’”

Barkana said that while the existence of dark matter is inferred from its strong gravity, astronomers have no idea what kind of substance it actually it is. As such, dark matter is one of the top remaining mysteries of physics.
