Well, a bit less than half the time it's black, and a bit less than that 
it's mostly blue of some shade. The remaining time is mostly reds and 
oranges, but there are definite attested and documented times for all of 
the above.

Likewise, gravity has remained the phenomenon of most unsupported 
material objects accelerating toward the earth, but the existence of the 
force supposed to cause this has come into serious question during the 
past century. It's still treated as a force for simplicity since it 
involves acceleration of mass, but the most peculiar geometric 
abstraction behind Einsteinian gravity is unlike anything else my 
physics text calls a force.
