Well good bye Solar system in round 2 and 3 cause Gohan is gonna blow it up because he is bloodlusted..
so stalemate? last time i checked gohan would die in the vacuum
Saiyans can survive in space.Goku went to the moon remember and bardock was fighting in space.
Going non canon...Nappa and Vegeta were also laughing in space, Paragus was in an ateroid field with Broly which who was loling his butt off tho that feat is canon to him.
