I heard that astronauts cannot burp in space. Is it true?


Actually, it is true!


In space, there is no gravity to pull things straight down, so the gas and liquids in the astronauts' stomachs don't seperate. This means the gas can't come back up to create a burp!  Or, at least, a burp like we would known on Earth. If the stomach contents move too close to the stomach valve, the astronauts will 'bomit'. I don't think you need the details about that!
