Antimatter appears to fall.

Scientists get closer to solving mystery of antimatter

Scientists have made a key discovery about antimatter - a mysterious substance which was plentiful when the Universe began.

Antimatter is the opposite of matter, from which stars and planets are made.

Both were created in equal amounts in the Big Bang which formed our Universe. While matter is everywhere, though, its opposite is now fiendishly hard to find.

The latest study has discovered the two respond to gravity in the same way.

For years, physicists have been scrambling to discover their differences and similarities, to explain how the Universe arose.

Well done those scientists on the work. It seems intuitive to me that antimatter would be affected by gravity just the same as matter. It's made up of subatomic particles just like matter, so why would it not? Intuition is not observation though.

No it shouldn't, it's antimatter, the opposite of matter.
It should behave in THE opposite manner of matter in every conceivable matter!

But would not anti-hydrogen readily react and combine with anti-oxygen to form anti-water? If so, is anti-water dry?

Of course, and your toe will hurt if you don't kick it on an antimatter rock.
