I've been looking around with google and I understand WHAT frequency is but I don't understand how it really works with light. For example, looking at a star if we are moving from it (or it's moving from us, or both) the light is red-shifted, but if we're moving towards it then it's blue-shifted. So, if I get in spaceship and fly towards this star at near the speed of light all I'll see is blue or something other than red right? But if I measure the speed of this light it'll still be c no matter if I'm moving from it, going towards it, or I'm standing still. How does that work? Are frequency and speed totally separate? Because it seems like they aren't when I look at all non-light examples on the net.
