Description: A common belief in Big Bang cosmology is that the cosmological redshift cannot be properly interpreted as a Doppler shift—that is, as evidence of galaxy velocities relative to a static background—but must instead be understood in terms of the stretching of space, or the change in time of distances between galaxies. However, this interpretation remains an open question and continues to be debated in the literature. In this project, we will analyze the relevant bibliography, assess whether the competing arguments are well-founded from the perspective of fundamental physics, and seek to arrive at a conclusion that clarifies this intriguing issue.
Building on this foundational analysis of redshift, the student will be guided through the calculation of its time-dependent evolution and encouraged to develop original predictions that could offer new insights into the universe’s accelerating expansion and large-scale structure. The ultimate goal is to determine whether these predictions can be tested with next-generation observational facilities.
