In these models the cosmological constant (dark energy) was needed. Two years later in another paper they suggested that . Later observations confirmed this value.

Explanation of Dark Energy in terms of vacuum energy and the cosmological constant. by rclark7083 in School Work, dark, and quantum

This has been called the coincidence problem, and has motivated theories beyond the cosmological constant with more general forms of dark energy that may change with time.

New data from the South Pole telescope has constrained how much dark energy could have existed in the early universes, shedding light on the cosmological constant and ...
