Harvard Astrophysicist Avi Loeb Suggests Interstellar Object 3I/ATLAS Could Contain Antimatter

Avi Loeb, a Harvard astrophysicist, has suggested that the interstellar object 3I/ATLAS could be composed of antimatter, a form of material that annihilates ordinary matter and releases nearly total energy on contact.

Loeb described antimatter as

"the most efficient fuel" in the universe
and argued that its interaction with solar particles could account for the object's unusual brightness and apparent acceleration.

According to Loeb,

"If 3I/ATLAS truly contained it, its passage through the solar wind might generate detectable gamma-ray or X-ray emissions-signals that NASA's Fermi Gamma-Ray Space Telescope could observe.

Author's summary: Avi Loeb suggests 3I/ATLAS contains antimatter.
