| 41. | So Einstein added a fudge factor that he called the cosmological constant to his equations.
|
| 42. | So far, however, the best argument in favor of a cosmological constant borders on silliness.
|
| 43. | Einstein called the force the " cosmological constant ."
|
| 44. | A prominent example in this context is the observed accelerating universe and the cosmological constant issue.
|
| 45. | Okay, now add a cosmological constant to this.
|
| 46. | "It's the specter of the cosmological constant ."
|
| 47. | This duality involves a model of spacetime called de Sitter space with a positive cosmological constant.
|
| 48. | The case is getting stronger for a cosmological constant or a wide range of quintessence models.
|
| 49. | The simplest explanation, other astrophysicists agree, is that the force is something called the cosmological constant.
|
| 50. | Here was where the cosmological constant came in.
