1.   But his fudge factor refused to die.

2.   Cosmic dust, a fudge factor as useful as the cosmological constant, might obscure a star or galaxy, making it appear farther away than it really was.

3.   It is a kind of antigravity force, a monumental fudge factor.

4.   Just a few years later, though, Einstein was rethinking his fudge factor.

5.   Of course, it was Einstein who originally ordered dark energy when he inserted a fudge factor called the cosmological constant into his gravitational equations describing the universe.

6.   Still, it makes them uneasy to be introducing such fudge factors.

7.   There can be no fudge factor in timing barbecue judging.

8.   Albert Einstein once referred to the cosmological constant as his biggest mistake, a fudge factor that he stuck into some equations just to make them work.
