Accelerated expansion and lightcurves

AI Thread Summary
The discussion centers on the relationship between time dilation associated with cosmological redshift and the accelerated expansion of the universe as observed in Type Ia supernovae since 1998. Participants question whether the photometric slowing of these supernova lightcurves is directly linked to this accelerated expansion. There is mention of the Pound-Rebka experiment, which verified gravitational time dilation, but the relevance to the current topic is unclear. The conversation highlights a potential gap in understanding how time dilation impacts the interpretation of supernova data. Overall, the connection between time dilation and supernova lightcurves in the context of cosmic expansion remains a point of inquiry.

Is the time dilation associated to cosmological redshift that can be seen as a photometric slowing of the SNe Ia lightcurves directly related to the accelerated expansion seen on these same type of supernova from 1998? If not, what's the difference?

Thanks

nobody here heard of the time dilation test? or lightcurves?
 
What time dilation are you referring to , I know they tested the gravitational red-shift of light , with the pound-Rebka experiment and verified gravitational time dilation

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
