I thought I had read within the past year that Type Ia supernovae (SNe Ia) have some variability due to variations in the amount of heavy metals. Is that true?

V = dx/dt and a = dV/dt This is basic stuff. Where is the dt in the evidence. I only see dv/dx. dv/dx is not evidence of acceleration but rather evidence that higher velocity exists at higher x. What do you say?

What is the prrof that there is dark energy. Is it the fact that greater red shift occurs at greater distances from us?
