    At what redshift does the density of M > density of DM

    I worked out the answer for z to be around 0.33, does that sound about right?

    Here is the problem link picture http://i.imgur.com/0BtcXJk.png I know that omega=density/critical density so I know I can find the value of all of those. DE is dark energy and M is matter (I'm pretty sure). I assume I have to sub that formula into equation 1, and then rearrange it to create a...
