My theory on the Kerbal universe.

[Souper]

My theory is that the Kerbal's universe has higher gravity then ours, different chemicals (Explodium in Eve's oceans) and Hydrogen is somehow easier to achieve fusion.

Or something like that.

For instance, if i were to place Earth in their universe, it would catastrophically collapse into a tiny fireball due to higher gravity.

If i place Kerbin in Our universe, it would explode like a mini supernova due to the lower gravity.

...Or maybe the Kerbal's kilometer is way larger then our own, and the Kerbol system is actualy a perfect 1:1 to our own. XD

The kerbalverse can't possibly have a higher G value. I ran the calculations a while back using the mass and size from the game. It works out.

Its probably scaled units or something.

Probably scaled units, yes.
