Spitzer confirms cosmological inflation

[popeyespappy]

Perhaps you misspoke there; the geologic timescale is a heartbeat in comparison with cosmic time.

Not really much difference as both deal in billions of years. Only way I would see a real significant difference would be if I still believed in the collapsing universes theory.

It is not believed to be constant because of the believed exponential effects of dark energy.

I don’t know if it has been proven, but is believed that the rate of expansion is accelerating therefore not a constant. But, is it accelerating at a constant exponential rate?
