Sal Cordova and Aging Galaxies

[swamidass (S. Joshua Swamidass)]

If the universe is old, and evolved and distant starlight travelled at a constant rate, we should see (by way of metaphor) a progression from young to old like this (give or take few fractions of a billion years):

Which is exactly what we see!

@stcordova

instead, with some adjustment for the bluer stars far away, the relative ages of big galactic structures look (metaphorically) like this:

Not at all. That is not what we see.

@stcordova

This is a known problem in cosmology.

If it is a known problem it is known for being resolved.

@physicists?
