we don’t need no “sticking” room 606

We are being evicted from Room 408. We were thinking of moving to Room 606 but have run up against a band of opportunistic cybersquatters. Ugh. The slow decline continues.

Picture frames and cosmic microwaves

I was thinking about that so called cosmic microwave background radiation stuff the other day…

I don’t really know a lot about it. My understanding is that this background radiation comes at us from all directions, more or less equally. But recently something occurred to me. When someone moves towards a light source, the light is blue-shifted. When someone moves away, the light is red-shifted. So can’t we then just look at the colour of the background radiation in different directions to define an absolute reference frame?

Please, enlighten me.
