https://goo.gl/images/ERMSEq actually he was still on named. Him being dead also does not take away his durability. His body still resisted being blown to bits from the planet explosion. This shows that even at his weakest, frieza can survive a planet explosion. You can't debunk this. It is literally shown.
You're showing me all of this science as if goku is a normal human... Goku may be similar to one, but he isn't... Superman is an example.
You've shown namek being earth size though so I concede there. Still doesnt take away the planet durability
@deathhero61: Setting an opinion on their durability without ki is really unfair. If frieza is weaker than ss1 goku then goku would survived it as well. And it doesn't matter if they can or can't breathe because they can easily travel to another planet in 5-10 minutes.
