Goku cannot breathe in space, just like any other Saiyan. If Superman isn't anywhere near a yellow or blue sun, he'll die soon enough.

Saitama can pretty much hold his breath for indefinite periods of time. Dr. Manhattan might have the same thing too. Saitama easily tanked a planet busting attack with ease, so, no, destroying the Earth wouldn't completely destroy him. He can also go a long way without eating or drinking anything for more than a few billion years in my opinion, considering his durability to survive a lightning bolt unscathed.

Also, see the intro. Saitama can jump in the empty vacuum of space without any medium with all his strength at high speeds.
