This is incorrect. The only measurement of antimatter gravity so far by ALPHA-g resulted in no difference to normal matter within the experimental uncertainty [

This is incorrect. The only measurement of antimatter gravity so far by ALPHA-g resulted in no difference to normal matter within the experimental uncertainty [1]. This is not surprising, since any difference would violate conservation of energy. [1] https://www.nature.com/articles/s41586-023-06527-1 https://www.nature.com/articles/s41586-023-06527-1
