The gravitational redshift formula is calculated using the equation: Δλ/λ = GM/Rc^2, where Δλ is the change in wavelength, λ is the original wavelength, G is the gravitational constant, M is the mass of the object causing the gravitational potential, R is the distance ...

Light rays received on earth from distant stars show redshift, being attributed conventionally to the well-known Doppler-effect of wave dynamics. The present study concludes that cosmic redshift rather is an effect of the quantum mechanical propagation of photons as explained by Nobel Laureate ...
The possibility to use both wavelength and frequency results from Planck's equation. You can see from the above redshift formula that the greater zz, the bigger the difference between emitted and observed light. Redshift and blueshift When the observed wavelength is smaller than emitted, the zz...

The Three Faces of Omega_m: Testing Gravity with Low and High Redshift SN Ia Surveys Peculiar velocities of galaxies hosting Type Ia supernovae (SNe Ia) generate a significant systematic effect in deriving the dark energy equation of state ... A Abate,O Lahav - 《Monthly Notices of the ...
Redshift distortion measurements from galaxy surveys include sensitivity to the gravitational growth index distinguishing other theories from Einstein gravity. This gravitational sensitivity is substantially free from uncertainty in the effective equation of state of the cosmic expansion history. We estimate th...
They measure this by calculating the doppler shift. The light from stars moving towards us is shifted towards the blue side of the spectrum, while stars moving away from us are red-shifted. Between the proper motion and redshift, you can get a precise calculation for the exact path a star...

Hello all, so I've always wondered about the expansion of the universe as indicated by the observed doppler (red) shift... i get the observed spectrum...
