minus-squarehperrin@lemmy.worldlinkfedilinkarrow-up3arrow-down2·1 year agoWhy would anything think it would fall up?
minus-squareMatch!!@pawb.sociallinkfedilinkEnglisharrow-up3·1 year agoBecause things exist (the antigravity hypothesis was an attempt to explain why matter and antimatter haven’t annihilated each other)
minus-squarefoyrkopp@lemmy.worldlinkfedilinkarrow-up2·1 year agoBecause one common assumption was that the universe might contain as much antimatter as matter. Which begs the question: Where did it go? We would notice a huge amount of annihilation reactions in the solar system. “Antimatter falls up” (is gravitationally repelled instead of attracted by normal matter) was an easy hypothesis to explain that.
