This is my first post :)

Einstein's special relativity finds that length is contracted if the observer is moving at high speeds. Now, assume there is a mass at rest in space that is below critical density of a black hole. If an observer were traveling at high speeds past this mass, the object will contract; therefore, placing the object above critical density. Are the existence of black holes relativistic?
