Overview

• Antimatter was first discovered in 1932 and is the opposite of normal matter, annihilating when the two meet.
• Scientists at CERN trapped antihydrogen atoms and observed their motion in a magnetic field to measure the effects of gravity.
• The results showed antimatter responds to gravity identically to normal matter, falling downwards rather than exhibiting antigravity.
• This finding supports Einstein's theory of general relativity and provides new insights into antimatter's properties.
• The imbalance between matter and antimatter in the universe remains an unsolved mystery.
