Frank, the "Observations" line never moves. Are you perhaps looking at one of Don Easterbrooks' predictions?
Oh, I see what you mean. This graph shows the pause. That's not very surprising Frank. Until Karl 2015, almost every graph did.
Check this out Frank. Before 1998, every astrophysicist on this planet assumed the expansion of the universe was slowing in response to the gravity field of the mass of the universe. Worst case was that it had reached a terminal velocity and would expand at its current velocity forever. But, in that year, " the
Supernova Cosmology Project and the
High-Z Supernova Search Team simultaneously obtained results suggesting a totally unexpected acceleration in the expansion of the universe by using distant
type Ia supernovae as standard candles."
The expansion of the universe was not decreasing. It was increasing. This was like finding that a ball rolling uphill accelerated. What this suggested caused a major revision in our fundamental understanding of cosmology and the nature of the universe. However, within two years it was the new dogma. So stand back and watch as the real experts demonstrate what its like to NOT have an agenda, to NOT have a theory you just won't give up, to NOT be wiling to go where the evidence leads, no matter the cost.
